Time Bar for Outstanding Ship Hire Claims: Unpaid Hire, Off-Hire Deductions and English Law

What is the Time Bar for Outstanding Ship Hire Claims?

When does a shipowner’s claim for unpaid hire become barred by time under English law?

In time chartering, hire is the financial foundation of the contract. The charterer obtains the commercial use of the ship for an agreed period, and the shipowner expects hire to be paid punctually in accordance with the charterparty. However, disputes often arise when the charterer deducts from hire, withholds part of a hire instalment, or stops paying hire altogether because the charterer alleges off-hire, underperformance, overpaid bunkers, speed and consumption issues, or another claim against the shipowner.

The important legal question is not only whether the charterer was entitled to make the deduction. A second and sometimes more dangerous question is when the shipowner must bring the claim for the unpaid hire. If the shipowner waits too long, the claim may become time-barred even though the shipowner believes that the deduction was unjustified.

Under English law, unless the charterparty contains a different contractual time limit or special wording, a claim for unpaid hire under a simple contract is normally subject to a six-year limitation period. The key point is that this period usually starts when the relevant hire instalment originally fell due, not when the charter is finally reconciled after redelivery.

Why Hire Deductions Create Time-Bar Problems

Hire is not treated in exactly the same way as freight under a voyage charter. In a time charter, the charterer may in certain circumstances be entitled to deduct from hire if the charterparty clearly allows the ship to be treated as off-hire, or if the charterer has a genuine and legally recognised set-off against the shipowner.

For example, a charterer may allege that the ship was off-hire because of a machinery breakdown, crane failure, deficiency of crew, detention connected with the ship, or another event covered by the off-hire clause. The charterer may also allege underperformance if the ship failed to meet the warranted speed and consumption performance under the charterparty. If the charterer makes a deduction in good faith and on a reasonably calculated basis, the deduction may be commercially understandable, but that does not automatically protect the shipowner from limitation problems.

The shipowner may later say that the deduction was wrong. The shipowner may argue that the ship was not off-hire, that the alleged underperformance calculation was incorrect, or that the charterer’s claim was not a valid set-off. If the dispute is not resolved quickly, limitation time continues to run. A shipowner who waits until the final account is prepared after redelivery may lose the right to claim some earlier unpaid hire instalments.

When Does the Cause of Action for Unpaid Hire Accrue?

The central legal concept is the accrual of the cause of action. In simple terms, a cause of action accrues when the claimant first has the right to sue for the unpaid amount. In the case of time charter hire, each hire instalment normally becomes payable on its own contractual due date. If the charterer fails to pay that instalment in full, the shipowner’s right to claim the shortfall normally arises at that time.

This means that unpaid hire is not usually treated as one single final balance that becomes due only at the end of the charter. Instead, each unpaid or underpaid instalment may create a separate claim. The limitation period may therefore run separately for each instalment from the date on which that instalment should have been paid.

This distinction is commercially important. A shipowner may assume that all hire disputes can be collected and presented after redelivery, but under English limitation principles that assumption can be risky. The final hire statement may be useful as an accounting document, but it does not necessarily postpone the date when the legal claim first arose.

London Arbitration 10/16 and the Outstanding Hire Claim

The issue was considered in London Arbitration 10/16, which concerned a dispute under an amended NYPE 1946 time charter governed by English law and subject to London arbitration. The charterparty required hire to be paid in advance, with payments falling due before the relevant hire period.

The charterer stopped paying hire from 7 January 2006. The charterer relied on alleged off-hire periods and other claims, including underperformance. Several hire instalments were not paid before the ship was redelivered on 22 March 2006. The shipowner commenced arbitration on 21 March 2012, shortly before the sixth anniversary of redelivery.

The shipowner argued that the claim was effectively a claim for the final balance of hire due on or after redelivery. On that view, the arbitration had been commenced in time. The charterer argued that the claims were already time-barred because each hire instalment created a separate cause of action when that instalment originally became due. The tribunal accepted the charterer’s argument.

The practical result was serious for the shipowner. The shipowner could not avoid limitation by characterising the dispute as a final hire balance claim. The unpaid hire instalments had fallen due earlier, and the six-year period had started to run from those earlier due dates.

Why the Final Balance Argument Failed

The shipowner’s first argument was that the dispute should be treated as a final accounting exercise after redelivery. The shipowner said that the amount claimed was the balance of hire finally due under the charter, rather than separate claims for separate hire instalments.

The tribunal rejected that approach. The claim was not created by redelivery. The claim arose because hire had not been paid on the dates required by the charterparty. Redelivery may have marked the end of the commercial relationship, but it did not create a fresh limitation date for hire instalments that had already become due.

This is an important lesson in time charter accounting. The final account may gather together hire, bunkers, expenses, off-hire adjustments, underperformance calculations, and other items, but the legal nature of each claim must still be identified. A hire instalment that was due in January is not necessarily transformed into a March claim simply because the final account was prepared in March.

Why Off-Hire and Set-Off Did Not Delay the Time Bar

The shipowner’s second argument was that the charterer had withheld hire on the basis of off-hire and equitable set-off, and that time should not start running until the legitimacy of those deductions had been finally decided. This argument was also rejected.

A charterer’s deduction, even if made in good faith, does not suspend the shipowner’s cause of action. If the hire was contractually due and the shipowner disputes the deduction, the shipowner has a claim from the due date of that hire instalment. A later tribunal decision about whether the deduction was correct does not normally restart or postpone the limitation period.

This point is commercially significant. A disputed off-hire deduction may remain unresolved for years, particularly where the parties continue trading, maintain negotiations, or wait for a final account after redelivery. Nevertheless, the shipowner should not assume that limitation is frozen while the parties argue over the validity of the deduction.

Six Years From the Due Date of Each Hire Instalment

The general conclusion is that, under English law and in the absence of special contractual wording, the time bar for an unpaid hire claim under a simple contract is normally six years from the date when the relevant hire instalment fell due. This is the date when the shipowner first had the right to claim the unpaid amount.

For example, if hire was due on 1 February 2026 and the charterer paid only part of it, the shipowner should treat the shortfall claim as arising on or about that due date. If hire was again underpaid on 16 February 2026, that second shortfall may have its own separate limitation period. The shipowner should therefore track each instalment separately rather than relying only on the final balance at the end of the charter.

The position may be different if the charterparty contains an express clause that changes when a claim becomes due, creates a special final account mechanism, imposes a shorter contractual claim-presentation period, or is executed as a deed. The governing law and arbitration clause must also be checked carefully. However, the safe working assumption in ordinary English law time charter disputes is that time starts when each unpaid hire amount first became payable.

Difference Between Limitation and Contractual Remedies

The time bar issue should not be confused with the shipowner’s other remedies for non-payment of hire. Many time charters contain withdrawal clauses, anti-technicality clauses, lien clauses, interest provisions, or rights connected with sub-freights and sub-hires. These remedies may be available much earlier than the expiry of the six-year limitation period.

A withdrawal clause may allow the shipowner to withdraw the ship from the charterer’s service if hire is not paid in accordance with the charterparty, provided the clause is strictly followed. If the charterparty requires an anti-technicality notice, the shipowner must give the notice correctly and allow the contractual cure period to expire before withdrawing. A defective notice or premature withdrawal may expose the shipowner to a claim from the charterer.

Limitation is different. It concerns the last date by which a claim must be commenced before it becomes barred by time. A shipowner may still have contractual remedies immediately after non-payment, but if the shipowner does not start arbitration or court proceedings within the relevant limitation period, the money claim itself may become unenforceable.

Practical Steps for Shipowners

Shipowners should keep a clear hire-payment chronology from the beginning of the charter. Each due date, payment received, deduction made, shortfall, protest, invoice, notice, and reservation of rights should be recorded. This is especially important where the charterer makes repeated deductions for off-hire, underperformance, weather routing, bunkers, cargo claims, or expenses.

When a deduction is disputed, the shipowner should not leave the matter unresolved indefinitely. The shipowner should identify the relevant hire instalment, calculate the shortfall, reserve rights in writing, and monitor the limitation date. If the amount remains unpaid, the shipowner should consider commencing arbitration in good time, especially where several instalments are close to the six-year deadline.

Shipowners should also avoid assuming that commercial negotiations will protect limitation. Discussions, promises to review accounts, without-prejudice exchanges, and ongoing reconciliation of the final hire statement may not stop time from running unless there is a legally effective standstill agreement or other binding arrangement. If the parties genuinely want to pause limitation, this should be documented clearly and professionally.

Practical Steps for Charterers

Charterers should also treat hire deductions carefully. If the charterer deducts for off-hire or set-off, the deduction should be made in good faith, supported by a reasonable calculation, and linked to the relevant charterparty wording or legal basis. Unsupported or excessive deductions may expose the charterer to a withdrawal risk, interest, legal costs, or a damages claim.

A charterer should also understand that a deduction does not necessarily eliminate the shipowner’s claim. If the shipowner disputes the deduction, the issue may remain alive until it is settled or determined. Where the shipowner delays too long, the charterer may have a limitation defence, but the charterer should not rely on limitation as a substitute for proper charterparty performance and accurate accounting.

Checklist for Outstanding Ship Hire Claims

Identify the exact hire instalment and contractual due date.
Check whether the hire clause requires payment in advance.
Calculate the amount paid, deducted, and outstanding.
Review the off-hire clause and any underperformance or set-off basis relied upon by the charterer.
Separate each hire instalment from the final balance account.
Check whether the charterparty contains any special claim-presentation or time-bar wording.
Confirm the governing law and arbitration or jurisdiction clause.
Record protests, reservations of rights, and payment correspondence.
Monitor the six-year limitation period for each unpaid instalment.
Consider arbitration or a standstill agreement before limitation expires.

Commercial Importance of the Time Bar

Outstanding hire claims can be large, especially in a long time charter or during a strong freight market. A series of disputed deductions may look manageable while the charter continues, but the total exposure can become significant by redelivery. If the shipowner does not control limitation dates, an otherwise valid claim may be lost.

The issue is also important for settlement strategy. Both parties need to know which claims remain legally alive. A charterer may be more willing to settle if the shipowner has protected the claim in time. A shipowner may have less bargaining strength if some instalments have already become time-barred. Accurate limitation analysis therefore affects both legal rights and commercial negotiation.

Conclusion

For outstanding ship hire claims under English law, the safest rule is simple: treat each unpaid or underpaid hire instalment as a separate claim that may become time-barred six years from the date that instalment originally fell due. Do not assume that time starts only from redelivery, final account preparation, or the later resolution of off-hire and set-off disputes.

London Arbitration 10/16 shows that a shipowner may lose the right to recover unpaid hire if arbitration is commenced too late. A disputed deduction does not normally postpone the accrual of the shipowner’s claim. Shipowners should therefore monitor hire due dates carefully, act promptly when deductions are disputed, and commence proceedings before the relevant limitation period expires.
