Liens in a Time Charterparty

Liens in a Time Charterparty

A lien clause in a time charterparty is a security mechanism, not a routine administrative provision. It can decide whether unpaid hire, charterers’ disbursements, general average contributions, sub-freights, bill of lading freight, overpaid hire, bunker claims, arrest expenses, and supplier claims remain ordinary unsecured claims or become claims supported by control over cargo, freight, or the commercial use of the ship.

The classic discussion begins with Clause 18 of the New York Produce Exchange (NYPE) Charterparty Form. In substance, the clause gives shipowners a lien upon cargoes and sub-freights for amounts due under the charter, including general average contributions. It also gives charterers a reciprocal lien on the ship for advance monies paid but not earned, and requires charterers not to allow liens or encumbrances incurred by themselves or their agents to prejudice the shipowners’ title and interest in the ship.

The clause looks short, but its operation is technically demanding. It raises questions about cargo ownership, bill of lading contracts, sub-charter chains, the timing of notice, freight already paid, the distinction between freight and hire, the difference between English and U.S. maritime law, company-charge registration, priority between competing assignees, and the consequences of arrest by cargo interests or suppliers.

The commercial reason for the clause is straightforward. A time charterer may control the ship commercially, issue employment orders, arrange cargoes, collect freight, buy bunkers, appoint agents, and sub-charter the ship. If that charterer defaults, the shipowner needs practical security. Clause 18 gives the shipowner tools to protect outstanding sums, while also giving charterers some protection for advance hire and unearned payments.

The legal effect, however, is not uniform. English law generally treats the cargo lien as possessory and contractual, while U.S. law may recognise maritime liens enforceable in rem. The same clause can therefore have different practical force depending on governing law, where enforcement is attempted, the identity of the cargo owner, and the terms of the bills of lading and sub-charters.

Commercial Function of Time Charterparty Clause 18

Clause 18 protects the shipowner against the risk that the time charterer may use the ship, earn freight from others, or load cargo, yet fail to pay hire or other amounts due under the head charter. The clause therefore gives the owner access to two principal forms of security: a lien over cargo and a lien over sub-freights.

The cargo lien operates by allowing the shipowner, in proper circumstances, to retain control of cargo rather than deliver it without payment or security. The sub-freight lien operates differently. It allows the shipowner to intercept money owed to the charterer or, in some cases, to parties lower in a charter chain, before that money is paid away.

In addition to these contractual rights, shipowners may have an independent right to intercept bill of lading freight where the bills of lading are shipowners’ bills and the freight is legally owed to the shipowner as carrier. That right is not the same as a Clause 18 lien on sub-freights, because the freight under a shipowner’s bill is not freight owed to the charterer. It is freight owed to the carrier.

The clause must be read with the commercial structure of a time charter. Time charterers are normally entitled to exploit the ship commercially, issue bills of lading in the ordinary course, collect freight, and manage the revenue stream while the charter is being performed. The lien is a protection against default, not a general right for shipowners to interfere with the charterer’s ordinary trading while hire and other sums are being paid.

What Sums Are Secured by the Lien in Time Charterparty

The NYPE wording secures “any amounts due under this Charter.” This expression includes hire that has accrued due and remains unpaid. It also includes sums that the charterers are required to bear under the charter but which have been paid or incurred by the shipowners on the charterers’ behalf, such as fuel costs, disbursements, port expenses, or other reimbursable expenditure, provided the charter makes those sums the charterers’ responsibility.

The important limitation is timing. The lien secures amounts that have accrued due when the lien is exercised. It does not secure hire that will only become due later, unless and until that later hire has actually accrued. This point was central in Samuel v. West Hartlepool, where the shipowner could rely on the lien for fuel, disbursements, and advance hire already due, but not for hire that became due only after the relevant freight had been collected.

Where the shipowner collects more than the amount properly secured, the surplus must be accounted for. The owner cannot treat a lien as a windfall. It is security for what is owed, not a right to keep all freight or cargo value regardless of the outstanding balance.

There remains some uncertainty under English law about whether the expression “amounts due under this Charter” includes unliquidated damages as well as debts. The Western Moscow discussed the point without finally resolving it. A claim for liquidated damages is more readily treated as falling within the expression. Demurrage in a voyage charter, as considered in Lyle Shipping v. Corporation of Cardiff, has been treated as a sum due under the relevant charter wording.

Payments earned outside the head charter are different. If, after withdrawal, the owner receives quantum meruit payments from a sub-time charterer for continued use of the ship, those payments are not “amounts due under” the head charter. The Lakatoi Express illustrates the distinction between sums arising under the charter and sums arising from a separate post-withdrawal arrangement.

General Average Contributions in Time Charterparty

Clause 18 also refers to general average contributions. At common law, a shipowner has a possessory lien over cargo preserved by general average sacrifice or expenditure. The lien arises when the sacrifice is made or the expenditure incurred, and it may be exercised for the benefit of all interests entitled to general average contribution, not only for the shipowner’s own benefit.

The decision in Castle Insurance v. Hong Kong Islands Shipping confirms the broad nature of the common law general average lien. Clause 18 gives an additional contractual security right. The practical effect is that, where general average contribution is due, the shipowner may have both general maritime security and a contractual basis for refusing release of cargo without security.

English Law and U.S. Law Treat Liens Differently

A central distinction must be kept in view. Under English law, the Clause 18 cargo lien is generally contractual and possessory. Under U.S. law, comparable wording may create maritime liens capable of enforcement by in rem proceedings. This difference affects both strategy and risk.

Under English law, the cargo lien allows the shipowner to retain possession of cargo as security. It does not normally create an independent proprietary maritime lien against cargo owned by strangers to the charter. Under U.S. law, maritime lien concepts are wider and may allow a claimant to proceed against maritime property itself, subject to notice, ownership, priority, and statutory rules.

This means that parties cannot safely assume that a lien clause has the same effect in every jurisdiction. A lien asserted at an English-law level may not defeat a third-party cargo owner. A U.S. arrest or in rem claim may involve different priorities. The governing law, the law of the place of enforcement, the wording of the charter, and the bill of lading structure all matter.

Shipowners’ Lien on Cargo Under English Law

Under English law, the cargo lien given by Clause 18 is a right to retain possession of cargo until the secured sums are paid. It is therefore a possessory lien. The right qualifies the owner’s ordinary obligation to deliver or discharge cargo because the owner may refuse delivery while the lien is being lawfully exercised.

The point was explained in The Boral Gas, where a voyage charter cargo lien was treated as a qualification of the undertaking to discharge. In a time charter context, the same commercial idea applies: if the shipowner validly exercises the lien, the refusal to release cargo is not merely a failure to perform the charter service. It is an exercise of contractual security.

A possessory lien is normally lost when possession is surrendered. If the cargo is released unconditionally, the security is usually gone. For that reason, the timing and manner of delivery, storage, landing, escrow arrangements, and any substitute security require careful handling.

The Cargo Lien Is Contractual Only

The NYPE cargo lien is also contractual. It exists because the charterparty says so. It does not automatically bind every cargo owner in the world. In general, contractual rights bind the parties to the contract and those who have otherwise consented to the relevant terms.

This is why the ownership of the cargo is crucial. If the cargo belongs to the charterers, the lien is easier to apply. If the cargo belongs to third parties, the charter clause alone may not give the shipowner a direct right against those third-party cargo owners. The owner may still have rights against the charterer, but it may lack a direct right to detain the third party’s goods unless the third party has agreed to the lien through a bill of lading, sub-bailment, or other effective contractual route.

The classic authority is Turner v. Haji Goolam, involving the ship Bombay. The Privy Council held that a time-charter lien clause could not give shipowners a right to seize a sub-charterer’s sugar for time-charter hire where the cargo owner had not contracted on terms giving such a lien. The court emphasised that a right to take one person’s goods for another person’s debt must be clearly conferred before it will be recognised.

Third-Party Cargo and Consent

Third-party cargo owners may still become bound by a cargo lien if they have consented to it. The most common method is incorporation of the lien clause into the bill of lading contract. If the bill of lading is a contract between the shipowner as carrier and the cargo interest, and it effectively incorporates the relevant time-charter lien clause, the cargo holder may be contractually bound.

Another route is sub-bailment. If the shipowner has possession of the cargo as sub-bailee on the terms of the time charter, and the cargo owner has consented to the sub-bailment on those terms, the lien may bind the cargo owner. The Pioneer Container explains the broader principle, and Jarl Trä v. Convoys gives an example where a cargo owner was bound by terms in the sub-bailment.

Where neither incorporation nor consent exists, the owner must proceed with great caution. Wrongful detention of third-party cargo can produce claims in conversion, damages, or other relief, even if the charterer has defaulted under the head charter.

Clause 18 as a Qualification of the Charter Service

Even where the shipowner lacks a direct right against the third-party cargo owner, Clause 18 may still operate as between owner and charterer. This means the owner may be entitled, as against the charterer, to refuse to perform the charter service of discharging the cargo until the secured sums are dealt with. The law on this point has been shaped by conflicting first-instance decisions.

In The Agios Giorgis, Mocatta J. held that shipowners were not justified, even as against the charterers, in detaining cargo belonging to third parties for unpaid hire where the third-party cargo owners were not bound by the lien. Shortly afterwards, Donaldson J. reached the opposite conclusion in The Aegnoussiotis.

Donaldson J. treated Clause 18 as meaning what it says between the parties: the charterers agreed that the shipowners should have a lien on all cargoes. If the cargo belonged to third parties, the charterers had undertaken to procure that a contractual lien would be created in favour of the shipowners. If the charterers failed to do so, they could not rely on their own breach to complain that the shipowner’s exercise of the lien was invalid against them.

The latter approach is commercially persuasive because it prevents charterers from promising security and then avoiding the consequence by failing to secure it in the documents used with cargo interests. Nevertheless, the law is not fully developed, and owners should not treat this reasoning as a licence to detain third-party cargo knowingly without any direct right against the cargo owner.

Charterers’ Promise to Procure a Lien

The better view is that Clause 18 includes an undertaking by charterers to procure a lien over cargo, whether or not the cargo is owned by the charterers. That undertaking is especially important where bills of lading are issued to third parties.

If the bills of lading fail to give the owner an effective lien, and the owner detains cargo in the honest belief that it has the promised right, the charterer may be liable in damages or under an indemnity for the owner’s exposure to the cargo interests. The answer may be different where the owner knows that no such right exists and nevertheless detains the cargo. A manifestly wrongful detention should not be converted into an indemnified act simply because Clause 18 exists.

The owner’s position also interacts with the rules on signing bills of lading. Clause 18 does not generally entitle the owner or master to refuse to sign bills merely because the bills do not reproduce the lien clause. That question belongs to the broader law on employment orders, bill of lading signing, and conformity with the charter.

Baltime Charterparty Form

The Baltime Charterparty Form is narrower. Its lien wording refers to cargoes and sub-freights belonging to the time charterers. That wording makes it clear that the cargo lien is not intended to cover cargoes owned by strangers to the charter. The Mihalios Xilas is important in this context.

This difference illustrates why parties should not speak of “the lien clause” as though all standard forms produce the same result. The exact form, edition, line wording, amendments, and rider clauses may materially alter the security available.

Incorporating the Cargo Lien into Bills of Lading (B/L)

Where shipowners’ bills of lading incorporate the time-charter lien clause, the owner may obtain a direct contractual right against bill of lading holders to lien the cargo for sums owed under the time charter. The Chrysovalandou Dyo supports this proposition.

General words of incorporation can sometimes be enough. In voyage charter cases such as Fidelitas v. V/O Exportchleb and The Miramar, broad incorporation wording was sufficient to bring a lien clause into the bills of lading. In the time charter context, however, caution is needed because a time charter is not always a natural set of carriage terms for incorporation into a bill of lading. The Nanfri contains important comments on this difficulty.

Incorporation also requires identification. The bill of lading must sufficiently identify the charter whose terms are being incorporated. Where the bill simply refers to “the charterparty,” courts often presume that the reference is to the head charter where that charter is a voyage charter and the shipowners are party to it, as shown by The San Nicholas, The Sevonia Team, and The Nai Matteini. Whether the same presumption applies where the head charter is a time charter is more uncertain.

Where and How the Cargo Lien May Be Exercised

A cargo lien is normally exercised at, off, or reasonably close to the discharge port. The shipowner exercises it by telling the charterers that delivery will be withheld under the lien. It is not usually exercised by stopping the laden ship somewhere on the voyage before the discharge port.

In The Mihalios Xilas, the shipowners halted the ship at a bunkering port on the voyage. Donaldson J. stated that a shipowner is not usually exercising a cargo lien merely by refusing to carry the cargo further. Refusal to complete the voyage might count only in special circumstances, such as where exercise of the lien at the destination would be impossible and further carriage would inevitably cause loss of possession.

It may, however, be proper to exercise the lien by anchoring off the declared discharge port rather than proceeding to the berth. In The Chrysovalandou Dyo, Mocatta J. rejected the argument that the owner had to go all the way to the exact discharging place. Requiring that step could impose unnecessary expense or cause congestion.

While a lien is being lawfully exercised, hire may continue to run under a time charter. The Chrysovalandou Dyo supports that result. Similarly, The Boral Gas indicates that demurrage under a voyage charter does not stop merely because the owner is reasonably and lawfully exercising a lien over cargo.

Landing Cargo and Maintaining Constructive Possession

The owner does not necessarily have to keep the cargo on board indefinitely. Once the lien has been exercised by refusing delivery at or off the intended discharge port, the owner may land the cargo to its own order, or in suitable circumstances move the ship to another port to do so. Mors-Le-Blanch v. Wilson and Cargo ex Argos illustrate the principle.

The key requirement is that the owner must retain actual or constructive possession to the exclusion of those who would otherwise be entitled to receive the cargo. If possession is surrendered unconditionally, the lien is normally lost.

While retaining the cargo, the owner remains a bailee. It owes a duty to take reasonable care of the goods. At the same time, the owner may recover reasonable storage and safeguarding costs from the charterers. The Lehmann Timber explains that the basis of recovery may depend on whether the charter has ended, but the practical point is that a lien does not release the owner from cargo-care responsibilities.

Loss or Waiver of the Cargo Lien

A cargo lien may be lost if the owner acts in a manner inconsistent with its continued existence. Popplewell J. summarised the principle in The Lehmann Timber. The issue is whether the owner’s conduct shows an intention to waive the lien.

Taking security may sometimes be inconsistent with preserving the lien, but not always. In The Lehmann Timber, the owners demanded both a general average bond and a guarantee. A guarantee was supplied but the bond was not. The owners had not waived their lien by accepting the guarantee because they maintained their demand for the bond. The Court of Appeal agreed.

The practical lesson is that any security arrangement should state expressly whether the cargo lien is preserved or released. Silence may create expensive argument.

Shipowners’ Lien on Sub-Freights

The lien on sub-freights is the owner’s main alternative security where cargo cannot be detained or where freight money is more accessible. It allows the shipowner, when the time charterer defaults, to step into the charterer’s place and claim freight owed to the charterer or, in some cases, to a sub-charterer lower down the chain.

In The Spiros C, Rix L.J. expressed the accepted principle: a lien over sub-freights gives the shipowner, where the time charterer has defaulted, the right to step in and claim payment of sub-freights for itself, provided those sub-freights have not already been paid.

The lien may apply to freight owed under charters or bills of lading, but only where that freight is owed to the charterer or sub-charterer. Where the bill of lading is a shipowner’s bill and freight is owed directly to the shipowner as carrier, the owner relies on its own freight right, not a lien over sub-freights.

Do Sub-Freights Include Sub-Hire

A difficult question under the 1946 NYPE wording is whether “sub-freights” include sub-time charter hire. The Commercial Court has produced conflicting views.

In The Cebu, Lloyd J. gave a wide interpretation. He held that “sub-freights” in the NYPE context included not only voyage-charter freight and bill of lading freight, but also sub-time charter hire and even sub-sub-time charter hire. He relied in part on older terminology reflected in Inman Steamship v. Bischoff, where “freight” in a marine insurance context was treated as the benefit derived from employment of the ship, including time-charter hire.

In The Cebu (No. 2), Steyn J. reconsidered the point and reached the opposite conclusion. He held that by the time of the relevant charters, the market had clearly distinguished freight from hire: freight meant bill of lading or voyage-charter freight, while hire meant remuneration under a time charter. He also considered the consistent use of “hire” elsewhere in the NYPE form. The issue has not been finally resolved at appellate level, but Steyn J.’s view is generally the more persuasive commercial interpretation of the 1946 wording.

The uncertainty was addressed in the 1993 revision of the NYPE form. NYPE 93 expressly adds “and/or sub-hire.” Where that wording applies, the clause is no longer limited to the older debate about whether sub-freights can include sub-time charter hire.

Legal Nature of the Sub-Freight Lien

Although called a lien, the sub-freight right is not a classic possessory lien. It concerns debts, not physical goods. The better English-law analysis is that it operates as an equitable assignment by way of charge over freight debts owed to the charterer, and over relevant security rights the charterer has in debts owed lower down a charter chain.

In The Ugland Trailer, Nourse J. reasoned that the lien must operate as an assignment, because it allows the shipowner to claim payment directly from the sub-charterer or shipper. Since the assignment is only security for the charterer’s obligations to the owner, it is properly characterised as a charge. This analysis was also adopted or supported in The Nanfri, The Annangel Glory, and The Attika Hope.

Lord Millett expressed a different obiter view in Agnew v. Commissioners of Inland Revenue, suggesting that the right might be a personal right to intercept a debt rather than a proprietary assignment. However, in The Western Moscow, Christopher Clarke J. preferred the earlier assignment-by-way-of-charge analysis. That remains the more practical basis for understanding the lien under English law.

Floating Charge Rather Than Fixed Charge

The sub-freight lien is best treated as a floating charge until it is exercised. Before default and notice, the charterer is free to collect sub-freights in the ordinary course and use the proceeds. The charge is dormant. It attaches to a changing class of freight debts, including future debts when they come into existence.

The charge crystallises when the owner serves notice of the lien on the freight debtor. That notice perfects the equitable assignment and prevents the debtor from validly paying the charterer instead. The Annangel Glory, The Western Moscow, and Cosco Bulk v. Armada Shipping explain this floating-charge character.

The rule in Tagart, Beaton v. James Fisher is central. Freight paid to the charterers’ collecting agent before the shipowner exercised the lien was treated as paid to the charterers. Once payment had occurred, the freight debt no longer existed as freight to be liened. The lien was lost.

The same logic does not protect a debtor who pays the charterer after receiving notice of the owner’s lien. After notice, payment to the charterer will not normally discharge the freight debt. The debtor remains exposed because it has dealt inconsistently with the equitable assignment.

The Perfected Assignment

Notice of lien perfects an equitable assignment of the freight debt as security for the charterer’s debt to the owner. It is not a legal assignment under Section 136 of the Law of Property Act 1925 because it does not satisfy the requirements for an absolute legal assignment. The relevant debts may be future debts and the transfer is conditional on amounts being due under the charter.

The result is an equitable security interest. The owner can sue the freight debtor as equitable assignee, usually joining the original creditor unless the court dispenses with that requirement. The owner also takes the assigned debt subject to equities, so the freight debtor may rely on defences, set-offs, arbitration clauses, and jurisdiction clauses that would have been available against the original creditor. The Jay Bola is important on this point.

Freights Owed to Sub-Charterers

The owner’s lien can sometimes reach freight owed not directly to the head charterer but to a sub-charterer lower down the chain. This depends on each relevant charter containing a lien clause that gives the intermediate charterer equivalent rights.

In The Cebu, a chain of NYPE time charters allowed the head owner to reach sub-sub-time charter hire because each link contained a lien clause. Lloyd J. treated the rights as successive equitable assignments. The Western Moscow later followed the logic for the wording before the court, explaining that equity treats as done what ought to be done where the successive assignments are contractually agreed.

The practical conclusion is that the owner may be able to reach the bottom of a charter chain only if the contractual rights exist at each link. If a sub-charter lacks a lien clause, or if there is no debt outstanding at a necessary point in the chain, the attempt may fail.

The result would likely be different under the Baltime wording because the Baltime lien is restricted to cargoes and sub-freights belonging to the time charterers.

Exercising the Sub-Freight Lien

The sub-freight lien is exercised by giving notice to the party who owes the freight: a sub-charterer, shipper, consignee, or other freight debtor. No special form is required, provided the notice clearly communicates that the owner is exercising its lien and that payment is to be made to the owner.

In The Attika Hope, Steyn J. stated that notice need not follow any particular form as long as the debtor is made aware that the assignment has taken place. In The Spiros C, Rix L.J. described notice as the act that perfects the right.

Timing is decisive. The lien bites only while the freight remains unpaid. If the freight has already been paid to the charterer or to the charterer’s authorised collecting agent, the lien is too late. This was the result in Samsun Logix v. Oceantrade, where freight had been paid into solicitors’ hands under freezing orders before the shipowner’s notice was served. The funds were treated as the charterer’s funds, not unpaid sub-freight still available to be liened.

Outstanding Debt Under the Head Charter

The owner cannot exercise the lien merely because it wants security. There must be an amount due and unpaid under the charter. The Annangel Glory makes clear that charterers are free to deal with sub-freights as their own unless and until amounts are outstanding and the owner gives notice.

Where a chain of charters is involved, the logic is more demanding. The head owner claims through the rights of the intermediate parties. It cannot be in a better position than its assignor. Therefore, there may need to be an outstanding debt at each relevant link before the right can pass all the way up the chain.

Effect of Notice on the Freight Debtor

Once the freight debtor receives notice of the equitable assignment, it must pay the owner rather than the charterer or sub-charterer. If it pays the assignor after notice, the payment will not usually discharge the debt. The debtor may then be required to pay again.

The principle is the same as the general rule for equitable assignments: after notice, the debtor cannot deal inconsistently with the assigned interest. The commercial risk for sub-charterers and shippers is therefore serious. They should stop, verify, and seek proper instructions if they receive a lien notice before payment has been made.

Anti-Assignment Clauses

A sub-charter may contain a clause prohibiting assignment of the right to receive freight. Under the general rule in Linden Gardens Trust v. Lenesta Sludge, such a prohibition can be effective. The Western Moscow indicates that an anti-assignment clause in a sub-charter may therefore prevent the head owner’s lien from operating on that freight debt.

This is a significant practical limitation. Owners relying on sub-freight security should not assume that the head charter clause alone is enough. The terms of the sub-charter and any anti-assignment wording may be decisive.

How Much of the Sub-Freight Is Assigned

There is a technical question whether the lien assigns the whole freight debt subject to the owner’s duty to account for any surplus, or only so much of the freight debt as is necessary to satisfy the owner’s claim. The Cebu appears to assume assignment of the whole freight debt, but the point did not have to be finally decided there.

In a charter chain, this question matters. If the whole debt is assigned at each stage, the head owner may claim the full debt subject to accounting. If only the necessary amount is assigned, the claim passed up the chain may be limited by the smallest outstanding debt at any link. Because the authorities have not fully resolved the issue, commercial drafting should avoid leaving it to implication where large sums are involved.

Accounting for Surplus

If the owner recovers more through a sub-freight lien than is owed under the head charter, it must account for the surplus. If the debt belonged to the charterer, the owner accounts to the charterer. If the debt originally belonged lower down the chain, the correct accounting route may be more complex because each party may have a separate interest in the balance.

The security nature of the lien is the controlling point. It secures what is owed; it does not transfer beneficial ownership of every recovered dollar beyond the secured debt.

Priority Between Competing Assignments

Where the charterer has assigned sub-freights to another party, priority may depend on the order in which notices are given under the rule in Dearle v. Hall. The Attika Hope illustrates the danger. A third-party assignee gave notice before the shipowners served their lien notice. The assignee had priority, and the sub-charterers, having later been persuaded to pay the freight to the shipowners, remained liable to pay again to the first assignee.

The practical lesson is simple: lien notices should be served promptly, and freight debtors should not pay without checking whether an earlier assignment notice has priority.

Registration as a Company Charge

If the time charterer is incorporated in England and Wales or Scotland, the owner’s lien on sub-freights may be treated as an equitable assignment by way of security and may need registration as a charge under Section 860 of the Companies Act 2006. If required registration is not made within the statutory period, the security may be void against a liquidator, administrator, or creditor of the charterer.

The Ugland Trailer and The Annangel Glory held that the instrument creating the charge was the time charter itself and that registration was required. The requirement is commercially awkward because time charters are not ordinarily handled like financing documents, but the statutory wording drove the result.

The practical impact is limited because the requirement does not apply to overseas companies merely because they have a place of business in the United Kingdom. Nevertheless, where an English or Scottish corporate charterer is involved, this issue should not be overlooked.

Shipowners’ Right to Intercept Bill of Lading Freight

Separate from the lien on sub-freights, a shipowner may have an independent right to intercept freight payable under a shipowner’s bill of lading. The distinction is essential. If the bill is a shipowner’s bill, the freight is owed to the shipowner as carrier. The owner does not need a lien over someone else’s freight debt; it is claiming its own freight.

In ordinary time-charter practice, the owner may be impliedly obliged to allow the charterer to collect bill of lading freight while the charterer is not in default. This is tied to the charterer’s Clause 8 employment right and the normal commercial use of the ship. The Bulk Chile recognises that unjustified interference with freight collection before default could be a serious breach by the owner.

Once the charterer defaults in paying hire or other amounts due, the owner’s implied obligation to let the charterer collect the freight no longer applies. The owner can then direct the shipper or bill of lading holder to pay freight to the owner instead, provided the freight has not already been paid.

Interception Through Collection Agents

Where the charterer has appointed an agent to collect freight, that authority exists only because the owner has allowed the charterer to exploit the ship commercially. The owner may revoke that authority when the charterer defaults and require the agent to collect for the owner instead.

In Molthes Rederi v. Ellerman’s Wilson Line, the owner successfully directed agents at the discharge port to collect freight for the owner’s account after the time charterer had fallen into arrears. The agents could not deduct disbursements incurred as agents for the time charterers from freight they had agreed to collect for the shipowners.

There is also older authority, including Wehner v. Dene, suggesting that an owner may sometimes intercept freight after the agent has collected it but before the agent has paid or credited it to the charterer. Later authority leaves aspects of this point open, so it should not be relied on without caution.

Where Bills Direct Payment to the Charterers

Modern bills often state that freight is payable to the charterer, or that freight is payable as per charterparty. The owner may still countermand the payment direction before payment is made if the bill is a shipowner’s bill and the charterer has defaulted. The Spiros C and The Bulk Chile confirm that the nominated recipient is treated as the owner’s agent for collection; that authority can be revoked before payment.

The phrase “freight payable as per charterparty” must be read in context. It can incorporate not only the freight rate but also the payment machinery in the sub-charter, including when and where freight is payable. In The Indian Reliance, sub-charterers who paid freight into the time charterers’ nominated account in accordance with the incorporated sub-charter payment terms were not required to pay again to the shipowners.

Similarly, in The Spiros C, the Court of Appeal held that shipowners asserting a bill of lading freight right were bound by certain deduction arrangements and payment arrangements made between the time charterers and sub-charterers before the owners intervened. The reason is that the owner had delegated collection to the time charterer in the ordinary course, and legitimate arrangements made before intervention could bind the owner’s later claim.

Freight Prepaid Bills of Lading (B/L)

A time charterer may be entitled to require the master to sign bills marked freight prepaid, even though Clause 18 gives owners a lien on sub-freights. The Nanfri is the leading authority. The lien clause must be read in the context of the time charterers’ primary right to use the ship commercially and direct the master in relation to that use.

If a bill of lading is marked freight prepaid, but freight has not in fact been paid when the owner intervenes, the owner’s rights may not be lost merely because of the label. The Nanfri and The Indian Reliance show that the actual legal and payment position must be examined.

The position is different where payment has actually been made in accordance with the bill or incorporated charter terms before the owner intervenes. Once the freight is validly paid, there may be nothing left to intercept.

Accounting After Intercepting Bill of Lading Freight

Where the owner intercepts bill of lading freight, it must account for any surplus after deducting the amounts due under the time charter. The unresolved question is whether that duty is owed to the time charterer or to the sub-charterer or other party lower in the chain.

In Wehner v. Dene, the owner accepted that it had to account to the sub-charterer, and the court dealt with the case on that basis. However, a strong argument remains that the duty to account arises from the time charter and is therefore owed to the time charterer. The answer can matter because it may affect whether sums falling due after freight collection can be set off against the surplus.

In practice, the safest approach is to calculate what had accrued due at the time of interception, preserve a clear account, and avoid distributing surplus without considering all contractual links and insolvency risks.

Charterers’ Lien on the Ship

Clause 18 also gives charterers a reciprocal lien on the ship for monies paid in advance and not earned. Similar wording appears in the Baltime form. This is not a true possessory lien because a time charterer does not possess the ship in the way a demise charterer does.

The better analysis is that the charterer’s “lien” gives a right to restrain the owner, at the end of the charter, from resuming commercial control of the ship for its own purposes until unearned advance payments are returned. Tonnelier v. Smith supports the idea that the provision makes advance payments provisional, not final. The Lancaster developed the point by treating the charterer’s remedy as one that could be enforced by injunction after redelivery subject to the lien.

The charterer’s lien does not give a proprietary interest in the ship. It does not attach to hull insurance proceeds after loss. The Lancaster rejected attempts to treat the lien as an equitable property right ranking ahead of mortgagee interests.

Charterers’ Obligation Not to Create Priority Liens or Encumbrances

Lines 112 and 113 of the NYPE wording require charterers not to suffer or permit any lien or encumbrance incurred by themselves or their agents that might have priority over the shipowners’ title and interest in the ship. This is a practical protection against arrests, supplier claims, cargo claims, and other maritime claims caused by charterers’ operations.

If the charterers or their agents cause the ship to be arrested by a claim that may rank against the ship, the charterers may be required to provide security to release the ship. The Vestland is a leading English authority. Cargo claims arose from charterers’ orders and their agents’ conduct. The ship was arrested in Canada. The court held that the shipowners were entitled to insist that charterers provide the necessary security because the statutory action in rem encumbered the ship and arose from the charterers’ side.

The expression “agents” does not necessarily include every person lower down a charter chain. It may include independent contractors or sub-contractors when they are performing tasks that charterers undertook to perform under the charter, such as cargo handling. This is a fact-sensitive question, and the reasoning in cases such as The Global Santosh shows that the word may have different scope depending on the clause under consideration.

The 1993 NYPE form added wording by which charterers undertake not to procure supplies, necessaries, services, port expenses, or bunkers on the credit of the shipowners or in the shipowners’ time. This addition addresses the practical danger of suppliers asserting liens against the ship for debts generated by charterers’ operations.

U.S. Law: Maritime Liens in Time Charterparties

U.S. law approaches liens through the concept of the maritime lien. A maritime lien is a right in maritime property itself, enforceable by an in rem proceeding against the ship, cargo, or freight. It travels with the property and can give the lienholder priority against other claimants, subject to established ranking rules.

The description in The Young Mechanic captures the classic character of a maritime lien: it is a real right enforceable against the thing itself, not merely a personal claim against one debtor. This is why maritime liens are powerful in U.S. chartering disputes.

Maritime liens may arise by general maritime law or by contract. Clause 18 liens are contractual in origin, but U.S. courts may enforce them as maritime liens if the legal requirements are satisfied. U.S. courts have also upheld choice-of-law arrangements linked to maritime liens where there is a sufficient connection with the United States, as shown by Liverpool & London S.S. Protection & Indemnity Association v. Queen of Leman and Trans-Tec Asia v. M/V Harmony Container.

Executory Contracts Under U.S. Law

A maritime lien for breach of charter does not arise while the charter is merely executory. In the case of a time charter, the charter ceases to be executory when the ship is delivered to the charterer or placed at the charterer’s disposal.

Rainbow Line v. The Tequila stated that delivery commences performance of a time charter and removes it from executory status. The Oceano similarly recognised that once charter-party performance begins, a lien may exist in favour of the shipper or charterer for liabilities arising from the shipowner’s breach.

Bank One Louisiana v. M/V Mr. Dean provides a detailed modern analysis. The court held that a maritime lien for breach of a time charter attaches when the shipowner places the ship at the charterer’s disposal. It remains inchoate until perfected by breach or discharged by completion of the charter without disturbance.

If the ship is never delivered, the charter remains executory and no charterer’s maritime lien arises. Boston Bermuda Cruising v. M/V Royal Majesty illustrates that result.

Union of Ship and Cargo Under U.S. Law

For liens relating to cargo, U.S. law requires a union between ship and cargo. A shipowner’s lien on cargo owned by the charterer cannot be enforced until the cargo is on board or otherwise within the ship’s control. Conversely, a cargo claimant’s lien on the ship for cargo loss or damage does not arise unless there has been a union of ship and cargo.

Authorities such as The Keokuk, Osaka Shosen Kaisha v. Pacific Export Lumber, Krauss Brothers Lumber v. Dimon Steamship, and related decisions show the importance of the physical and contractual connection between the ship and the cargo.

Shipowner’s Lien on Cargo and Sub-Freights Under U.S. Law

U.S. courts recognise a shipowner’s right, under general maritime law, to lien the charterer’s own cargo for hire due under the charter unless the charter provides otherwise. The Bird of Paradise and Jebsen v. A Cargo of Hemp are important examples. Clause 18 reinforces this right by contract.

The lien on the charterer’s cargo may arise inchoately on execution of the charter but cannot be enforced until cargo is loaded. American Steel Barge v. Chesapeake & Ohio Coal Agency and Luckenbach Overseas v. Subfreights of the Audrey J. Luckenbach treat the right as relating back to the charter date in important priority contexts.

The scope of “amounts due” was explained in The Freights of The Kate. The lien covers sums due and payable at the relevant time, including hire, advances, coal, provisions, port dues, and other sums that the charter required the charterer to pay. It does not automatically cover future or contingent liabilities that are not yet payable.

Where the cargo belongs to a third party rather than the charterer, the shipowner does not have a lien on the cargo for the charterer’s hire debt merely because Clause 18 exists. Goodpasture v. The Pollux is the key warning. The shipowner arrested cargo that still belonged to Goodpasture, not the charterer, and the arrest failed. The court also treated the wrongful arrest as conversion of the goods.

Even where no lien exists on third-party cargo, the owner may have a lien on sub-freights owed by that third party to the charterer. Chembulk Trading v. Chemex held that a clause granting a lien on “all cargoes and all freights” gave the owner a lien on sub-freights owed to the charterer.

When the U.S. Shipowner’s Lien May Be Exercised

Under U.S. law, the shipowner’s lien on cargo or sub-freights generally becomes exercisable only when the charterer is in default in payment of hire or another amount due under the charter. Authorities including Union Industrielle et Maritime v. Nimpex International and Marine Traders v. Seasons Navigation support that requirement.

The lien also depends on the cargo or freight not having been unconditionally released or paid. United States v. Freights of the Mt. Shasta, The Searaven, and N.H. Shipping v. Freights of the Jackie Hause illustrate the significance of release and payment.

In Arochem v. Wilomi, crude oil discharged to a lightering ship was not treated as unconditionally released. The court reasoned that a charter clause creating a lien for freight and demurrage would be futile if the lien necessarily disappeared before the relevant sums became due after delivery. The intended commercial security therefore survived the particular delivery arrangement.

The U.S. lien on sub-freights may be asserted directly against the party owing the sub-freight and does not require a claim against the cargo. Tarstar Shipping v. Century Shipline confirms that the lien is non-possessory in this respect.

Notice and Double Payment Risk Under U.S. Law

A sub-charterer or shipper who pays sub-freight before notice of the owner’s lien will usually discharge the obligation. Payment after notice is different. A debtor who pays the charterer after actual notice of the owner’s lien may be required to pay again.

Tarstar Shipping v. Century Shipline is a strong example. The sub-charterer had received oral and written notice of the owner’s lien before its agent actually paid the charterer. The sub-charterer failed to make a prompt good-faith effort to stop the payment. It was held liable to the owner for the full sum.

U.S. courts differ on whether constructive notice is sufficient. Recent decisions such as Lykes Lines v. M/V BBC Sealand and Finora v. Amitie Shipping emphasise actual notice. Older decisions such as The Solhaug and East Asiatic Trading v. Navibec Shipping were more willing to rely on constructive notice. Because the authorities are not fully uniform, a shipowner should give clear actual notice wherever possible.

Cornish Shipping v. Ferromet also shows that once the shipper has paid the sub-freight to the charterer’s agent, the funds may no longer be sub-freights. The lien may then remain effective against the shipper if payment was made after notice, but not against the charterer’s own money as if the money still retained its character as sub-freight.

Freight Prepaid Bills Under U.S. Law

If freight prepaid bills of lading are issued by or with the authority of the shipowner and negotiated to third parties, the owner may be unable to assert a lien on sub-freights or cargo. The Searaven illustrates the risk. Once prepaid bills have passed to purchasers for value without notice, the lien may be discharged and cannot necessarily be restored by later security.

Other cases in liner contexts, such as National Shipping Company of Saudi Arabia v. Omni Lines and Strachan Shipping v. Dresser Industries, show that the words freight prepaid do not always release a shipper where freight was not actually paid to the carrier. The outcome depends on the contractual and documentary context.

Self-Help Under U.S. Law

U.S. law may allow some self-help by refusing delivery or stopping discharge where the lien is valid, but self-help has limits. The lienholder cannot convert the cargo to its own use. If retention of the cargo does not resolve the debt, in rem proceedings and judicial sale may be necessary.

In The Lenoudis Kiki, arbitrators accepted that owners were justified in stopping discharge to force payment of overdue hire. In The Sally Stove, a similar result was reached where discharge of steel pipes was suspended because hire was overdue.

By contrast, in The Mistral, arbitrators ordered discharge without assertion of a lien where most freight had been paid, the remaining sums were not due until after discharge, and the bills were marked freight prepaid. The difference shows that self-help depends heavily on the timing of payment obligations and the status of the underlying lien.

Charterer’s Liens Under U.S. Law

U.S. general maritime law recognises that a charterer may have a maritime lien on the ship for breach of charter by the shipowner after performance has begun. The Oceano stated that damages sustained by a charterer through breach of a charter contract constitute a lien on the ship.

In Rainbow Line v. The Tequila, the shipowner prematurely withdrew the ship from service. The charterer obtained an arbitration award and then brought an in rem action. The court held that the charterer had a maritime lien because the damages flowed directly from breach of a maritime charter.

E.A.S.T. v. The Alaia and Bank One Louisiana v. M/V Mr. Dean follow the principle that the lien attaches once the ship is delivered and the time charter is no longer executory. If the owner later breaches, the inchoate lien may be perfected by that breach.

Not every charterer loss creates a lien. European-American Banking v. The Rosaria and Interocean Shipping v. The Lygaria rejected liens for prospective lost profits. In The T.T. Tula, the charterer had no lien for overpaid charter hire on the facts before the court.

Priority of Charterer’s Liens in U.S. Law

Maritime lien priority can be decisive where the ship is sold in foreclosure. A charterer’s lien for breach of charter is generally a contract lien of lower priority than crew wages, salvage, and tort liens. However, it may have preferred status if it arises before a preferred ship mortgage is recorded.

In Rainbow Line v. The Tequila, a maritime lien arising from a charter entered before the mortgage had priority over the later mortgage. Bank One Louisiana v. M/V Mr. Dean confirmed the same logic even though the breach occurred after the mortgage was recorded, because the lien had attached inchoately when the ship was delivered under the charter.

If the charter is entered after the mortgage is recorded, the mortgage will usually have priority, as shown by Kopac International v. The Bold Venture.

Liens for Supplies Ordered by Charterers

Clause 18 also seeks to prevent suppliers, repair yards, bunker sellers, stevedores, and other providers from obtaining liens on the ship for goods or services ordered by charterers. The clause requires charterers not to allow liens or encumbrances that may prejudice the owner’s interest.

Older U.S. cases, including Schilling v. A/S D/S Dannebrog, United States v. The Lucie Schulte, United States v. Carver, and Dampskibsselskabet Dannebrog v. Signal Oil, recognised that a prohibition of lien clause could defeat a supplier’s lien where the supplier knew or should have known of the restriction.

Later statutory developments under the Federal Maritime Lien Act and its successors gave suppliers of “necessaries” a strong position. Necessaries include repairs, supplies, towage, drydock use, fuel, lubricants, stevedoring, pilotage, food, equipment, and many other items needed for the ship’s business or operation. Cases such as Bermuda Express v. The Litsa, TTT Stevedores v. The Jagat Vijeta, Galehead v. M/V Anglia, and Equilease v. The Sampson show the breadth of the concept.

The U.S. Supreme Court’s decision in Exxon Corporation v. Central Gulf Lines removed the old categorical distinction between general and special agency contracts. The focus is now on the maritime nature of the services and whether they supply necessaries to the ship.

Actual Notice of No-Lien Clauses

Under modern U.S. law, a supplier may often rely on a statutory presumption that the person ordering necessaries had authority to bind the ship. The shipowner may defeat the lien by showing that the supplier had actual knowledge of a prohibition of lien clause or facts sufficient under the relevant law to remove that authority.

Cases such as Marine Fuel Supply v. The Ken Lucky, Gulf Oil Trading v. The Caribe Mar, and Lake Union Drydock v. The Polar Viking demonstrate that actual knowledge of the no-lien clause is usually required. Knowledge that the ship is under charter is not always enough. Ramsay Scarlett v. The Koh Eun stated clearly that a supplier of necessaries has no duty of inquiry merely because a charter may exist.

This is why owners frequently instruct masters or agents to stamp invoices, delivery receipts, and order forms with a notice that the ship is operating under a charter containing a prohibition of lien clause. To be effective, the supplier must receive the notice before or at the time the goods or services are provided. Stamping after bunkers have already been supplied is too late, as Gulf Oil Trading v. The Freedom illustrates.

As between owner and charterer, the charterer has the duty to prevent such liens and to give appropriate notice. If the charterer fails to do so and the ship is arrested or security is required, the owner may have an indemnity claim against the charterer, including bond costs and related expenses. Awards such as The Irene’s Grace, The George Vergottis, and The Scotiacliffe Hall illustrate this practical consequence.

Waiver and Assignment of Supplier Liens

A supplier can waive a maritime lien, but waiver requires a clear intention to rely solely on other security. Nacirema Operating v. The Al Kulsum and related cases show that courts do not lightly infer waiver. In Gulf Trading v. The Hoegh Shield, the bunker supplier retained a lien even though it relied partly on the time charterer’s credit because it had not clearly given up the lien against the ship.

Maritime liens may also be assigned or acquired by subrogation. Medina v. Marvirazon recognised subrogation to seamen’s wage liens where funds were advanced to discharge them, subject to equity. Other cases involving bunker intermediaries, including Tramp Oil v. The Mermaid I, Galehead v. M/V Anglia, and A/S Dan-Bunkering v. M/V Zamet, show that the contractual chain by which necessaries are ordered and paid can determine whether an intermediary obtains a lien.

Sub-Charterer’s Lien Against the Ship

In theory, a sub-charterer may have a maritime lien on the ship for breach by a disponent owner. But if the head charter contains a prohibition of liens clause and the sub-charterer has sufficient notice of it, the sub-charterer’s ability to assert such a lien may be restricted.

In MMI International v. Skyros, the prohibition of liens clause in the head charter precluded the sub-charterer from exercising a lien for breach by the charterer. Cardinal Shipping v. The Seisho Maru and United States v. The Lucie Schulte support the importance of no-lien restrictions where the relevant party has adequate notice.

Obligation to Free the Ship From Arrest

When a ship is arrested, the allocation of responsibility between owner and charterer depends on why the arrest occurred and which party’s breach or operational responsibility caused it. The general commercial principle is that the party whose breach caused the arrest should bear the cost of obtaining release, but each case turns on the charter and the facts.

In The Pandora, the charterer’s failure to pay hire caused the owner to exercise a cargo lien. Arbitrators held that the charterer was liable for expenses incurred by the owner in preserving and exercising the lien because the need for the action arose from the charterer’s default.

In The Wismar, the ship was arrested by a sub-charterer in Canada for claims against the registered owner. The arbitrators held that the registered owner had the duty to secure release because the arrest concerned claims against the owner, not actions of the time charterer or its agents.

In The Scotiacliffe Hall, by contrast, receivers arrested the ship at the discharge port in connection with claims against the charterer. Although the receivers were not the charterer’s agents, the detention was attributable to the charterer’s side, and the charterer was held responsible under Clause 18.

The Ming Belle shows that not every cargo-related security delay is for charterers’ account. After a grounding, salvors sought security. Cargo security was delayed, but the panel found no charter provision obliging the charterer or sub-charterer to post salvage security on behalf of the cargo owner.

The Gabrielle Wesch illustrates a more severe result. A Guatemalan arrest based on a cargo claim against the charterer from an unrelated voyage detained the ship for more than a year. The panel treated the arrest as attributable to the charterer under Clause 18, even if the arrest might later be challenged locally. The charterer was held liable for hire and expenses resulting from the arrest.

In Seguros Banavenez v. The Oliver Drescher, the Second Circuit warned against compelling a charterer to provide security to the owner without a proper adjudication of rights and without protection of the charterer’s position. The decision shows that even where one party may ultimately owe an indemnity, courts are cautious about forcing security without procedural fairness.

Charterer’s Property On Board

Equipment owned by charterers but placed on board may be subject to maritime liens against the ship if it becomes an integral part of the ship and essential to its operation. The Tropic Breeze treated charterer-owned cement equipment as subject to maritime liens because it was essential to the ship’s function as a bulk cement carrier. Other cases have applied similar reasoning to refrigeration equipment, diving bells, pumps, oil tanks, nets, and fishing gear.

Attachment depends on title. In Wave Maker Shipping v. Hawkspere Shipping, creditors sought to attach bunkers supplied by a sub-charterer. The bunker contract was governed by English law and retained title in the seller until full payment. Because the sub-charterer had not paid, title remained with the supplier and the bunkers were not property of the sub-charterer available for attachment by its creditors.

Filing Notices of Lien

The Marine Transportation Security Act of 2002 amended 46 U.S.C. § 31343 to permit filing notices of liens against United States documented ships even where no mortgage is of record. This is part of the wider U.S. statutory system governing maritime lien visibility and ship title records.

Practical Drafting Lessons

The lien clause should not be copied mechanically. Parties should decide exactly what security is intended, which debts are covered, whether damages and indemnity claims are included, whether sub-hire is covered, whether the lien extends down a charter chain, and how surplus will be accounted for.

If owners want the right to intercept sub-hire, the clause should say so expressly. Reliance on the word “sub-freights” in older wording creates uncertainty. NYPE 93 solved this by adding sub-hire. A rider clause can achieve the same result where older forms are used.

Bills of lading should be aligned with the charter. If owners expect a cargo lien to bind bill of lading holders, incorporation must be effective and the relevant charter must be sufficiently identified. If charterers expect to issue freight prepaid bills in the ordinary course, the charter should not leave the master uncertain about signing authority.

Where the charterer is an English or Scottish company, the possible registration of a sub-freight lien as a charge should be considered at the time the charter is concluded. The issue cannot be repaired easily after insolvency has occurred.

Where charterers buy bunkers or order necessaries, the charter should state clearly that such supplies are on charterers’ credit and not on the credit of the shipowners or the ship. Owners should use practical notice procedures, including timely invoice stamps, supplier notices, and master instructions, especially where U.S. law or U.S. ports may be involved.

Where a lien notice is served, it should be immediate, clear, correctly addressed, and supported by a calculation of the sums due. The notice should identify the ship, charter, unpaid amount, freight debt, debtor, payment direction, and reservation of rights. Ambiguity increases the risk that the debtor will pay the wrong party or interplead the funds.

Operational Lessons for Shipowners

A shipowner considering a lien should first verify the debt. Hire, reimbursable expenses, fuel costs, port disbursements, demurrage-like sums, or general average contributions should be identified and supported by documents. A lien exercised without an amount due may expose the owner to serious claims.

The owner should then identify the property or debt to be secured. Is the cargo owned by the charterer or a third party? Are the bills of lading shipowners’ bills or charterers’ bills? Has freight already been paid? Has a collection agent received the funds? Does an anti-assignment clause exist? Are there competing assignments? Has any security been accepted that may waive the lien?

The owner should also consider whether the place of enforcement is suitable. A cargo lien at the discharge port, a sub-freight lien by notice, an intervention in bill of lading freight, an arrest under U.S. law, and a claim against charterers for indemnity are different tools with different risks.

Finally, the owner must preserve cargo and evidence. Even when exercising a valid lien, the owner remains responsible as bailee for reasonable care of the cargo. Notices, photographs, storage arrangements, agent instructions, statements of facts, and cost records should be maintained carefully.

Operational Lessons for Charterers

Charterers should treat Clause 18 as an active operational duty. They must avoid allowing suppliers, agents, stevedores, bunker sellers, sub-charterers, shippers, receivers, or other parties to create liens or encumbrances that may prejudice the ship.

When ordering bunkers, port services, or cargo operations, charterers should ensure that suppliers know they contract on charterers’ credit unless the owner expressly agrees otherwise. The charterer should also check whether local law gives suppliers powerful maritime liens despite contractual no-lien wording.

Where the charterer sublets the ship, it should align the head charter and sub-charter. If the head owner has a lien on sub-freights or sub-hire, the charterer should understand whether its own sub-charter gives corresponding rights. Mismatch can leave the charterer paying the head owner without being able to recover from the sub-charterer.

Charterers should also monitor freight collection. If a lien notice is received, payment should not be made casually. The debtor should check whether the notice is valid, whether freight remains unpaid, whether competing notices exist, and whether court or arbitral directions are necessary.

Commercial Importance of Lien Rights

Lien rights are commercially important because time chartering creates separated control and separated revenue. The owner supplies the ship, but the charterer often earns freight from third parties. If the charterer becomes insolvent, the owner’s ordinary personal claim may be worth little unless security can be found in cargo, sub-freights, bill of lading freight, or claims against the charterer for failing to prevent liens against the ship.

At the same time, lien rights are dangerous if used aggressively without legal foundation. Wrongful detention of cargo, misdirected freight notices, interference with the charterer’s trading before default, or failure to account for surplus may expose owners to damages, conversion claims, injunctions, or reputational harm.

The strongest position is created before any default occurs. Clear charter wording, effective bill of lading incorporation, express treatment of sub-hire, supplier no-lien notices, aligned sub-charters, proper charge registration where needed, and disciplined payment monitoring make later enforcement more reliable.

Conclusion

Liens in a time charterparty are part of the financial safety system of the charter. They protect shipowners against unpaid hire and other amounts due, but they also protect charterers by recognising their interest in advance payments and by defining responsibility for liens or encumbrances created through charterers’ operations.

Under English law, the cargo lien is generally possessory and contractual, the sub-freight lien is best understood as an equitable assignment by way of floating charge, and the right to intercept bill of lading freight depends on whether the freight is owed to the shipowner as carrier. Under U.S. law, maritime lien principles, in rem enforcement, supplier rights, actual notice, priority, and statutory rules may produce a different result.

The practical lesson is that a lien clause should be managed from fixture to final account, not opened for the first time after default. Owners, charterers, brokers, masters, agents, and claims teams must know what the clause secures, how notice is given, when freight has already escaped the lien, how cargo possession is preserved, and who must provide security if the ship is arrested.

A well-drafted and properly operated lien clause can convert an unsecured charter debt into effective commercial protection. A poorly understood lien clause can create new liabilities as quickly as it protects old claims. That is why liens in a time charterparty require careful drafting, prompt action, accurate records, and a clear understanding of the law governing the charter and the place where enforcement may occur.
