Bills of Lading and Documentary Credits: Payment Structures, Credit Types, and Legal Principles

Bills of Lading and Documentary Credits: Payment Structures, Credit Types, and Legal Principles

Documentary credits are designed to reconcile the competing interests of sellers, buyers, and banks in international trade. The seller seeks reliable payment, the buyer wants assurance that the contractual shipping documents have been produced, and the financing bank requires a workable right of reimbursement and, where possible, security over the goods.

The system operates through a set of autonomous but commercially connected contracts. Payment is not made because a bank has inspected the goods or resolved disputes under the sale contract. It is made because the beneficiary has presented documents that comply with the credit. This documentary principle explains both the strength of the system and many of the disputes that arise under it.

Documentary credits can provide immediate payment, deferred payment, acceptance of a Bill of Exchange, or negotiation of drafts and documents. They may be confirmed or unconfirmed, transferable or non-transferable, revolving, back-to-back, or used in standby form. Each structure allocates payment, insolvency, documentary, and enforcement risks differently.

Payment Under Documentary Credits

Why Payment May Be Deferred

An irrevocable credit gives the seller the benefit of an undertaking from a financially reliable bank. Because payment no longer depends solely on the buyer’s solvency or willingness to perform, the seller may accept payment at a later date rather than insist on immediate cash against documents.

Modern credits often provide directly for deferred cash payment. In Anglo-American practice, however, deferred payment has traditionally been structured through an acceptance credit under which the bank agrees to accept a Bill of Exchange drawn by the beneficiary. The Bill of Exchange commonly matures at a fixed period, such as 90 days after sight.

The deferred structure does not necessarily leave the seller without immediate liquidity. The accepted Bill of Exchange can normally be discounted with a bank, allowing the seller to receive cash before maturity, subject to deduction of interest and commission.

Bills of Exchange

Definition and Essential Form

The legal obligations arising under Bills of Exchange are principally governed by the Bills of Exchange Act 1882. A Bill of Exchange is an unconditional written order, signed by the person giving it, directing another person to pay a fixed or determinable sum of money on demand or at a stated future time to a specified person, that person’s order, or the bearer.

The instrument must be in writing and must be signed. These formal requirements help explain why Bills of Exchange have adapted less easily to electronic commerce than some other trade documents. Although electronic systems continue to develop, traditional paper Bills of Exchange remain in use in the United Kingdom and in many international transactions.

The Parties to a Bill of Exchange

The principal parties are the drawer, drawee, and payee. The drawer creates and signs the order. The drawee is the person directed to pay. The payee is the person entitled to enforce payment. Depending on the structure, the drawer or drawee may also be the payee.

In an acceptance credit, the seller as beneficiary commonly acts as drawer and payee, while the issuing or confirming bank is the drawee. The bank becomes primarily liable only after accepting the bill. A drawer cannot impose liability unilaterally on a drawee, but the credit contains the bank’s contractual undertaking to accept the bill when conforming documents are presented.

Negotiability

A Bill of Exchange is a negotiable instrument. Negotiation transfers the right to enforce it. A bearer bill may be negotiated by delivery, while an order bill is negotiated by indorsement and delivery.

This characteristic distinguishes a Bill of Exchange from a Bill of Lading (B/L). A Bill of Lading (B/L) is a document of title, but it does not give a transferee better title to the goods than the transferor possessed. The principle that no one can transfer better title than they have therefore applies to a Bill of Lading (B/L).

A holder in due course of a Bill of Exchange may obtain stronger protection. A person taking a complete and regular bill in good faith, for value, and without notice of dishonour or a defect in title can avoid certain defects affecting earlier holders. Subsequent holders claiming through a holder in due course may receive the same benefit.

Negotiation With or Without Recourse

Where a Bill of Exchange is negotiated with recourse, the indorser may be required to reimburse a later holder if the drawee dishonours the bill and proper notice is given. Negotiation without recourse excludes that liability and leaves the subsequent holder bearing the risk of non-payment.

This distinction is fundamental in documentary credits. A confirming bank that negotiates a draft should do so without recourse to the beneficiary. Once it has paid, the confirming bank bears the risk that the issuing bank later refuses or becomes unable to honour the draft.

An unconfirmed negotiating bank may reserve a right of recourse. If the issuing bank fails to pay, the unconfirmed bank can then recover the advance from the beneficiary under the agreed terms.

Negotiation Under UCP 600

Under UCP 600, negotiation is not limited to the purchase of a Bill of Exchange. Article 2 defines negotiation as the purchase by the nominated bank of drafts and/or documents under a complying presentation by advancing or agreeing to advance funds to the beneficiary.

Merely examining documents does not amount to negotiation. The concept requires the giving of value or a binding commitment to give value in exchange for the drafts or documents.

The UCP 600 definition revived the express idea of purchase used in earlier revisions and clarified the less precise language of UCP 500. The commercial essence remains that the bank advances funds and acquires rights connected with the drafts or documents.

Sight and Time Drafts

A sight bill is payable on presentation. A time bill becomes payable at a fixed future time, commonly calculated from sight, acceptance, shipment, or another agreed event.

Time bills are commonly used in acceptance credits. The drawee bank accepts the bill after presentation, and payment falls due at maturity. The beneficiary can retain the accepted bill or discount it for immediate cash.

The discounted amount will be less than the face value because the bank deducts interest for the period until maturity and may charge a commission. Economically, the distinction between sight payment and a time draft often concerns which party bears the financing cost.

Under a sight structure, the issuing bank may finance the buyer and charge interest until reimbursement. Under a time-draft structure, the seller may discount the instrument and absorb the financing cost through the discount.

Deferred Payment, Acceptance, and Negotiation Credits

Acceptance Credits

Under an acceptance credit, the beneficiary draws a time draft on the bank identified in the credit. When the beneficiary presents conforming documents, the bank accepts the draft and becomes liable to pay it at maturity.

A confirming or nominated bank may discount the accepted draft and provide immediate cash. Because the Bill of Exchange is negotiable, the discounting bank can acquire rights independent of disputes under the sale contract and may also avoid certain defences that could have been raised against the original beneficiary.

Deferred Payment Without a Bill of Exchange

A Bill of Exchange is not essential. A deferred payment credit can provide that the bank incurs a direct obligation to pay on a future date after a complying presentation.

This approach has become increasingly common, particularly in jurisdictions without an active market for discounting trade bills. It can also avoid stamp duty and the formal requirements associated with paper Bills of Exchange.

A bank wishing to advance funds before maturity can purchase or take an assignment of the beneficiary’s rights under the deferred payment undertaking. UCP 600 also permits negotiation through the purchase of documents rather than a draft.

Negotiation Credits Drawn on the Applicant

Earlier credit structures sometimes required the beneficiary to draw on the applicant, with the issuing bank undertaking to negotiate the draft. Such arrangements created confusion because some parties assumed that the applicant, rather than the bank, bore the primary payment obligation.

UCP 500 discouraged drafts drawn on the applicant. UCP 600 goes further. Article 6(c) provides that a credit must not be issued available by a draft drawn on the applicant.

Article 6(b) requires the credit to state whether it is available by sight payment, deferred payment, acceptance, or negotiation. Article 2 defines honour according to the selected method: payment at sight, incurring and paying a deferred payment undertaking, or accepting and paying a Bill of Exchange at maturity.

Principal Types of Documentary Credit

The most important distinctions concern whether the credit is revocable or irrevocable and whether it is confirmed or unconfirmed. The first distinction concerns the issuing bank’s undertaking. The second concerns whether another bank adds its own independent obligation.

Other labels, including transferable, back-to-back, revolving, and standby, describe particular commercial structures. Their meaning must be determined from the credit wording and applicable rules rather than from the label alone.

Irrevocable and Revocable Credits

Irrevocable Credits Under UCP 600

UCP 600 defines a credit as irrevocable. Article 3 confirms that a credit is irrevocable even if the document does not expressly use that word.

An irrevocable credit constitutes a definite undertaking by the issuing bank to honour a complying presentation. A complying presentation is one that satisfies the credit terms, UCP 600, and international standard banking practice.

Article 10(a) states that, except where Article 38 applies to transferable credits, a credit cannot be amended or cancelled without the agreement of the issuing bank, confirming bank if any, and beneficiary.

The beneficiary therefore receives a bank undertaking that cannot be withdrawn merely because the buyer changes its mind, raises a sale dispute, or encounters financial difficulty.

Revocable Credits

A revocable credit may still be created outside UCP 600, but it offers little practical security. The issuing bank can withdraw or alter it without the beneficiary’s agreement, and at common law the bank may not be required to notify the seller before revocation becomes effective.

Because such a structure does not provide the reliable payment commitment expected from a documentary credit, UCP 600 does not recognise revocable credits as credits within its definition.

Confirmed Credits

The Confirming Bank’s Independent Undertaking

A confirmed credit arises when a second bank adds its own definite undertaking to honour or negotiate a complying presentation. The confirming bank’s promise is additional to the issuing bank’s obligation.

The beneficiary can deal directly with the confirming bank and rely on its credit standing and jurisdiction. If the issuing bank later fails to reimburse the confirming bank, the confirming bank cannot normally recover from the beneficiary after honouring a complying presentation.

A bank that merely advises a credit does not become a confirming bank. In Panoustos v. Raymond Hadley Corporation of New York, wording stating that the advising bank acted only as agent for its foreign correspondent and accepted no responsibility for continuation of the credit did not amount to confirmation.

UCP 600 Article 8 codifies the confirming bank’s obligation. The confirming bank must honour or negotiate in accordance with the credit, and its confirmation becomes irrevocable from the time it is added.

Negotiation by a Confirming Bank

A confirming bank may negotiate drafts drawn by the beneficiary on the issuing bank. This differs from the prohibited practice of issuing a credit available by drafts drawn on the applicant.

The confirming bank must negotiate without recourse to the beneficiary. It therefore assumes the risk that the issuing bank will not honour the drafts or reimburse the confirming bank.

Forestal Mimosa Ltd v. Oriental Credit Ltd

In Forestal Mimosa Ltd v. Oriental Credit Ltd, the sellers drew 90-day drafts on the confirming bank under an acceptance credit. The issuing bank later rejected the shipping documents following instructions from the buyers, and the confirming bank refused payment at maturity.

The Court of Appeal held that the alleged documentary discrepancies were unsustainable and that the confirming bank was bound by its own undertaking. Its liability was independent of the buyer’s refusal and the issuing bank’s position.

The case illustrates the commercial value of confirmation. Once the confirming bank has undertaken to accept and pay complying drafts, it cannot avoid liability merely because another party later challenges the documents.

A Requested Bank May Decline to Confirm

An issuing bank cannot impose confirmation obligations on another bank without consent. UCP 600 Article 8(d) recognises that a bank asked to confirm may decline and may instead advise the credit without confirmation.

The requested bank should inform the issuing bank without delay so that the credit can be routed through another institution if confirmation is essential. Advising without confirmation does not create the additional independent payment undertaking.

Confirmation of Deferred Payment Credits

Discounting an Accepted Bill

Where a confirming bank discounts a Bill of Exchange accepted under the credit, it becomes holder of the instrument and can claim payment from the relevant drawee at maturity. The negotiable instrument may protect the bank from defences arising under the underlying sale.

The amount paid to the beneficiary is reduced to reflect interest and costs until maturity. The confirming bank later claims the full face value of the bill.

Discounting Without a Bill of Exchange

Under a deferred payment credit without a Bill of Exchange, a confirming bank can advance funds by taking an assignment of the beneficiary’s rights. At common law, an assignee ordinarily obtains no better right than the assignor.

This distinction became important in Banco Santander SA v. Bayfern Ltd.. Banco Santander discounted a deferred payment credit, but fraud by the beneficiary was discovered before maturity. The Court of Appeal held that the issuing bank could rely on the beneficiary’s fraud against Banco Santander because Banco Santander claimed as assignee.

The decision exposed a difference between discounting an accepted negotiable instrument and prepaying a deferred payment undertaking.

UCP 600 Reversal of the Santander Result

UCP 600 was drafted to protect nominated and confirming banks that prepay or purchase deferred payment undertakings. Article 12(b) authorises a nominated bank to prepay or purchase such an undertaking, while the reimbursement provisions protect a bank that has acted on a complying presentation.

Under UCP 600, the position of a bank discounting a deferred payment credit is therefore closer to that of a bank negotiating an accepted Bill of Exchange. The issuing bank’s reimbursement obligation is intended to remain independent of the later discovery of beneficiary fraud, subject to the precise application of the fraud exception and the credit terms.

Unconfirmed Credits

Advising Banks

An irrevocable credit may remain unconfirmed even where a correspondent bank advises it in the seller’s country. An advising bank authenticates and communicates the credit but does not, by advising alone, undertake to honour or negotiate.

UCP 600 Article 9 governs the advising function. The advising bank must satisfy itself as to the apparent authenticity of the credit or amendment and accurately transmit the terms received.

An advising or nominated bank may agree separately to discount or negotiate, but unless it confirms the credit, its payment may be made with recourse to the beneficiary.

Unconfirmed Negotiation Credits

Under an unconfirmed negotiation credit, a nominated bank may purchase drafts or documents without adding its own irrevocable payment undertaking. If the issuing bank fails to reimburse it, the negotiating bank can reserve a right of recourse against the beneficiary.

The commercial difference from confirmation is therefore substantial. A beneficiary paid by a confirming bank without recourse has final payment. A beneficiary paid by an unconfirmed negotiating bank may remain exposed to issuing-bank dishonour.

Maran Road Saw Mill v. Austin Taylor & Co. Ltd.

In Maran Road Saw Mill v. Austin Taylor & Co. Ltd., Malaysian sellers required payment under irrevocable credits because the arrangement enabled them to borrow from their own bank. The credits provided for payment after 90 days but allowed drafts to be negotiated at sight rate by Bangkok Bank.

Bangkok Bank did not confirm the credits. It paid the sellers at sight rate and sent the documents to the issuing bank, which released them under a trust receipt. Before the drafts matured, the issuing bank entered liquidation and the bills were dishonoured.

Bangkok Bank exercised recourse against the sellers, who reimbursed it. The sellers then recovered from the buyers because the purchase price had not ultimately been received.

The court explained that a confirming bank would have had no recourse against the beneficiary, while a non-confirming negotiating bank was entitled to impose recourse as a condition of negotiation. The bank acted as principal when purchasing the draft and could determine the terms on which it advanced funds.

Commercial Value of Confirmation

An unconfirmed negotiation credit does not protect the seller from issuing-bank insolvency or wrongful refusal. The seller may need to pursue the issuing bank in a foreign jurisdiction and may also have to reimburse the negotiating bank.

Confirmation removes much of this exposure but carries an additional fee. Where the issuing bank is reputable and located in an acceptable jurisdiction, the seller may decide that an unconfirmed irrevocable credit is commercially sufficient.

In Enrico Furst & Co. v. WE Fischer Ltd., sellers accepted a credit issued by a reputable Italian bank without London confirmation and were held to have waived the requirement for confirmation. The court observed that confirmation would have made little commercial difference in the circumstances.

Assignment of Proceeds

Assignment of proceeds must be distinguished from transfer of the credit. A named beneficiary ordinarily remains the only party entitled to present documents and perform under the credit.

UCP 600 Article 39 permits assignment of the proceeds according to applicable law. The assignee can receive money that becomes payable to the beneficiary, but the assignee does not acquire the right to present shipping documents or perform the beneficiary’s obligations.

The original beneficiary remains responsible for making a complying presentation. The assignee’s rights are no better than the beneficiary’s rights and depend on payment becoming due under the credit.

Transferable Credits

Commercial Purpose

A transferable credit is useful where the beneficiary is an intermediary purchasing goods from one or more suppliers. The intermediary is the first beneficiary, while the suppliers become second beneficiaries.

The first beneficiary can use the buyer’s credit to provide payment security to its suppliers without opening an entirely separate credit from its own resources.

The transferred credit generally follows the original terms, but the amount, unit price, expiry date, latest shipment date, and presentation period may be reduced to accommodate the intermediary’s mark-up and the time required to substitute documents.

Requirements Under UCP 600 Article 38

A credit is transferable only if it expressly states that it is transferable. The first beneficiary may then request the authorised bank to make all or part of the credit available to one or more second beneficiaries.

The bank is not obliged to transfer merely because the credit is designated transferable. UCP 600 protects the bank by allowing it to refuse the transfer request and by requiring transfer charges to be borne by the first beneficiary unless otherwise agreed.

The rules also address amendments. The first beneficiary must state whether it retains the right to accept or reject amendments on behalf of second beneficiaries, and the possibility that different second beneficiaries may respond differently must be managed.

Only One Transfer Is Permitted

Fractions of a transferable credit may be transferred separately where partial drawings or shipments are permitted. This enables the first beneficiary to pay several suppliers.

A second beneficiary cannot transfer the credit again. The one-transfer rule protects banks from an uncontrolled chain of unknown beneficiaries and repeated administrative complexity.

Protecting the Middleman

The first beneficiary may substitute its own name for the applicant’s name in specified documents, subject to the UCP rules. This can prevent the supplier from discovering the identity of the ultimate buyer.

The first beneficiary can also replace the second beneficiary’s invoice with its own invoice for a higher amount and thereby retain the commercial mark-up.

Confidentiality is therefore central. The transferable credit enables the intermediary to protect both supplier identity and profit margin.

Jackson v. Royal Bank of Scotland

In Jackson v. Royal Bank of Scotland, the bank mistakenly disclosed the intermediary’s mark-up to the applicant. The disclosure encouraged the applicant to deal directly with the supplier in later transactions.

The court recognised an implied duty of confidence. The first beneficiary was entitled to keep its profit margin secret, and the issuing bank was required to protect that confidential information.

The case confirms three practical functions of a transferable credit: providing secure payment to the supplier and intermediary, concealing the supplier’s identity where required, and protecting the intermediary’s profit margin.

Back-to-Back Credits

A transferable credit can be transferred only once, making it unsuitable for long chains of intermediate sales. Back-to-back credits provide a different solution.

Under a back-to-back structure, the beneficiary of the first credit uses that credit as security for a second credit opened in favour of its supplier. The beneficiary under the first credit becomes the applicant under the second.

The two credits are legally separate. Each has its own applicant, beneficiary, bank relationships, terms, and reimbursement arrangements. The second credit is not a transfer of the first.

The credits are normally aligned as closely as possible, with differences for price, timing, and documents required to preserve the intermediary’s margin and allow document substitution.

A supplier can use the second credit to support a third credit for its own supplier, so the structure can theoretically continue through a chain of sales.

The expression “back-to-back” has practical rather than independent legal significance. Each credit remains autonomous, but the same shipping documents may be needed throughout the chain. A discrepancy or rejection at one stage can therefore disrupt several connected credits.

Revolving Credits

A revolving credit is designed for a sale involving repeated shipments over an agreed period. The seller needs assurance that payment support will remain available for the full supply programme, while the bank may wish to limit its maximum outstanding exposure.

One approach is a credit covering the entire contract value, with each shipment drawing down the total amount. This gives the seller strong protection but exposes the bank up to the full contract price.

A revolving credit instead sets a maximum amount available at any one time. Each drawing reduces the available balance, and reimbursement by the buyer restores the credit to the agreed ceiling.

In Nordskog & Co v. National Bank, expert evidence described a revolving credit as one that automatically renews as earlier drafts mature and are paid. No separate renewal instruction is required.

The arrangement limits the bank’s maximum outstanding liability while allowing repeated use. The seller’s protection is weaker than under a credit covering the full contract value because continued availability depends on the buyer reimbursing the bank.

The credit should specify whether it revolves by time or value, whether unused amounts accumulate, the maximum total utilisation, expiry, documentary requirements for each shipment, and circumstances in which the bank may suspend further drawings.

Standby Letters of Credit

Legal and Commercial Character

A standby Letter of Credit (LC) resembles a documentary credit in form but operates more like a bank guarantee or performance bond. It is triggered by default or alleged default rather than by ordinary completion of the seller’s performance.

Under a commercial documentary credit, the bank has a primary obligation to pay against conforming documents. The seller ordinarily looks first to the bank.

Under a standby Letter of Credit (LC), the primary obligation remains with the buyer or other principal debtor. The bank pays only when the beneficiary presents the demand or documents required to establish that the principal has failed to perform.

The standby bank also lacks the traditional security obtained under a documentary credit. It may not receive an Original Bill of Lading (B/L) or any other document of title and may therefore have no pledge or constructive possession of the goods.

Why Standby Credits Are Used

Standby credits are useful where traditional documentary conditions are impractical. They may guarantee payment where the Original Bill of Lading (B/L) cannot move through the trading chain before discharge or where the underlying transaction has no carriage element.

They can also secure performance by a seller or contractor. The bank agrees to pay if the beneficiary presents a demand stating that the seller has failed to perform or presents other stipulated evidence of default.

Performance Security Provided by Sellers

A seller may provide a guarantee or bond protecting the buyer against late delivery, defective performance, or complete non-performance. The trigger may be an independent expert determination, a certificate, a judgment, an arbitration award, or a simple demand.

A sale contract may alternatively retain part of the price until the buyer accepts the goods. For example, 90% may be payable against shipping documents and 10% after inspection or final acceptance.

Such a retention can undermine the documentary credit principle if payment depends entirely on the buyer’s subjective satisfaction. The clause should therefore define an objective inspection standard, a time limit, and a dispute resolution procedure.

A direct obligation by the seller to pay an agreed amount for breach must be assessed under the law governing penalties and liquidated damages. A genuine and proportionate pre-estimate or protection of a legitimate interest may be enforceable, while an oppressive penalty may not be.

On-Demand Performance Bonds

A bank-issued performance bond gives the buyer a claim against a reputable financial institution rather than an unknown or foreign seller. The bank’s obligation is autonomous and is enforced according to the bond terms.

Some bonds are payable against simple demand. The bank does not investigate the underlying merits unless fraud or another recognised exception is established.

Because of the possibility of an abusive demand, sellers sometimes price the transaction on the assumption that part of the bond amount may be called or may never be recovered.

Standby Security Provided by Buyers

A buyer may provide a standby Letter of Credit (LC) to guarantee payment. This is particularly useful in bulk oil sales where the cargo is frequently resold during a short voyage and the Original Bill of Lading (B/L) cannot reach the final receiver before discharge.

Delivery commonly occurs against a Letter of Indemnity (LOI), while the original bills are negotiated later. A conventional documentary credit requiring timely presentation of the Original Bill of Lading (B/L) may therefore be commercially impractical.

The standby may require a copy of the commercial invoice, a copy of the Bill of Lading (B/L), and a seller’s statement that the buyer failed to pay by the due date. The bank pays against these documents even though it receives no document of title.

In The Delfini, the standby mechanism required copies of the invoice and Bill of Lading (B/L), together with a seller’s certificate of non-payment. In The Filiatra Legacy, the required package could include a Letter of Indemnity (LOI) warranting title where the full set of bills was unavailable.

The documents provide some evidence of performance, but they do not give the bank security over the cargo. Unless the buyer provides collateral or advance funds, the bank may remain an unsecured creditor for reimbursement.

Standby credits can also secure transactions without carriage documents. In Elder Dempster Lines Ltd v. Ionic Shipping Agency Inc., a standby Letter of Credit (LC) guaranteed payment in a ship transaction where a traditional cargo documentary credit would have been unsuitable.

Application of UCP 600 to Standby Credits

UCP 600 applies to standby Letters of Credit (LCs) only to the extent that its provisions are applicable and only where the standby incorporates the rules.

Many UCP provisions concerning commercial transport documents may be irrelevant because standby credits often require different evidence or only a simple demand.

The diversity of standby structures makes it difficult to identify a single list of applicable articles. This has encouraged the use of separate rules such as ISP98, which were developed specifically for standby practice.

Reimbursement Between Banks

UCP 600 Article 7(c) requires the issuing bank to reimburse a nominated bank that has honoured or negotiated a complying presentation and forwarded the documents. Article 8(c) contains the corresponding obligation for a confirming bank where another nominated bank is involved.

Article 13 addresses bank-to-bank reimbursement arrangements. The credit or reimbursement authorisation should identify the reimbursing bank, applicable rules, currency, timing, charges, and place of reimbursement.

The place of reimbursement can affect jurisdiction and governing law. UCP 600 does not resolve every question concerning where reimbursement must be made, so the parties should state the position expressly.

Reimbursement by the Buyer

The issuing bank’s right to reimbursement from the applicant ordinarily depends on the bank having honoured the credit according to its mandate. The bank also claims its agreed commission, interest, and expenses.

In Sale Continuation Ltd v. Austin Taylor & Co. Ltd., the bank unsuccessfully argued for reimbursement despite not having made the payment required under the credit.

A separate security arrangement may still be enforceable. If the bank releases documents to the buyer under a trust receipt, the bank may be able to enforce the trust obligations independently of whether it has completed payment under the credit.

Governing Law of Documentary Credits

Why Governing Law Matters

Documentary credits commonly involve parties and banks in several jurisdictions. The UCP does not provide a comprehensive governing-law rule, and many credits contain no express choice.

Governing law can determine the validity and interpretation of the credit, the effect of injunctions and attachments, documentary standards, defences, and the ability to serve proceedings outside the jurisdiction.

Each contract within the documentary credit structure is autonomous, so different laws could theoretically govern the sale, issuing-bank mandate, confirmation, reimbursement, and bank-beneficiary undertaking.

Express Choice of Law

English law generally respects an express choice of law made in good faith and not contrary to public policy or mandatory rules.

In Vita Food Products Inc. v. Unus Shipping Co. Ltd., the court upheld an English governing-law clause despite the transaction having only a limited connection with England. The principle supports commercial certainty in sale chains and transferable carriage documents.

An express clause can ensure that successive transactions are governed consistently even where the parties change. This is particularly valuable in sale strings, back-to-back credits, transferable credits, and Bills of Lading (B/L) passing through several holders.

Mandatory legal provisions of a country closely connected with the contract may nevertheless apply despite the chosen law. Parties cannot always avoid consumer protection, sanctions, insolvency, or other overriding legislation through contractual selection.

No Express Choice of Law

Where the contract contains no choice, English courts identify the law with which the contract has the closest and most real connection. Under modern conflict rules, attention is also given to the country of the party providing the characteristic performance, subject to displacement where the overall circumstances point more strongly elsewhere.

Documentary credit cases have often treated the place of payment and presentation as particularly important because that is where the bank’s obligation to the beneficiary is performed.

Offshore International SA v. Banco Central SA

In Offshore International SA v. Banco Central SA, a Spanish bank issued a credit through Chase Manhattan Bank in New York. Payment in USD and presentation of documents were to occur in New York.

The court held that New York law governed the bank-beneficiary relationship. The significant performance obligations were centred in New York, while Spain was primarily the source of the issuing bank’s undertaking.

Power Curber International Ltd. v. National Bank of Kuwait SAK

In Power Curber International Ltd. v. National Bank of Kuwait SAK, an unconfirmed credit financed a CIF sale between a seller in North Carolina and a buyer in Kuwait. Payment and document presentation were arranged through a North Carolina bank.

A Kuwaiti attachment order later prevented payment under Kuwaiti law following a sale dispute. The English Court of Appeal held that North Carolina law governed the credit because payment and presentation were to take place there.

The Kuwaiti order was not allowed to defeat the autonomous bank undertaking recognised under the governing law of the credit.

Marconi Communications International Ltd. v. PT Pan Indonesia Bank Ltd.

In Marconi Communications International Ltd. v. PT Pan Indonesia Bank Ltd., the confirming bank had its principal place of business in Indonesia, but drafts were negotiated and payment was made in London through Standard Chartered Bank.

The Court of Appeal held that English law governed because the transaction had an overriding connection with England. The place of payment and presentation displaced the presumption based on the confirming bank’s principal place of business.

Bank of Baroda v. Vysya Bank Ltd.

In Bank of Baroda v. Vysya Bank Ltd., the court also favoured English law where confirmation and performance occurred through an English branch, despite the international identity of the banks and parties.

The case reflects a judicial preference for applying one coherent law to closely connected bank contracts where possible.

The Relationship Between the Autonomous Contracts

The Doctrine of Infection

Although each documentary credit contract is autonomous, courts have recognised that applying different legal systems to every banking relationship may create serious commercial inconvenience.

The legal or commercial connection between contracts can support an implied intention that related contracts are governed by the same law. This approach is sometimes described as the doctrine of infection.

The starting point is often the contract between the beneficiary and the paying bank. Once its governing law is identified from the place of payment and presentation, the same law may be applied to the reimbursement relationship between banks.

In Bank of Baroda v. Vysya Bank Ltd., the court considered the confirming bank’s characteristic performance and aligned the governing law of the connected banking contracts. The court regarded fragmented governing laws as commercially undesirable.

A similar approach has been taken with performance bonds and counter-guarantees, including Turkiye Is Bankasi AS v. Bank of China and Wahda Bank v. Arab Bank plc.

The Underlying Transaction Remains Separate

Courts are more willing to separate the governing law of the credit or performance bond from the law governing the underlying sale, construction, or service contract.

This separation reflects autonomy. The beneficiary may deliberately require bank security payable in a jurisdiction and under a legal system different from the law governing the commercial contract.

Attock Cement Co. Ltd. v. Romanian Bank for Foreign Trade

In Attock Cement Co. Ltd. v. Romanian Bank for Foreign Trade, the underlying construction contract was governed by English law, while a Romanian bank issued an unconditional performance bond payable on demand.

When disputes arose, the beneficiary argued that English law should also govern the bond. The Court of Appeal rejected that conclusion. The underlying contract’s governing law did not determine the law of the separate bank undertaking.

The proper law of the bond depended on the place of payment and the connections of the bond itself, which pointed away from England.

Wahda Bank v. Arab Bank plc similarly recognised that a commercial party may seek payment security from a bank in a jurisdiction different from that governing the main contract. The bank undertaking must therefore be analysed independently.

Documentary Compliance and the Allocation of Risk

Payment under a documentary credit is triggered by documents, not by direct proof that the goods conform physically to the sale contract. This creates a disciplined and efficient payment system but also places substantial importance on precise drafting and presentation.

The seller must ensure that invoices, transport documents, insurance records, certificates, and drafts comply on their face. A documentary discrepancy can justify refusal even where the goods themselves are satisfactory.

The buyer receives protection because the bank will not honour an irregular presentation. The bank receives protection because it deals within an area of documentary expertise rather than investigating commercial performance.

The beneficiary receives protection because the bank cannot normally refuse payment by relying on disputes under the underlying sale. The autonomy principle prevents the applicant from using ordinary contractual allegations to stop a complying presentation.

Commercial Selection of the Appropriate Credit

The appropriate structure depends on the transaction rather than on a single preferred form. A seller requiring immediate final payment may seek a confirmed sight credit. A buyer needing financing may prefer deferred payment or acceptance.

An intermediary with one level of suppliers may use a transferable credit. A longer sale chain may require back-to-back credits. A regular supply agreement may justify a revolving credit.

A standby Letter of Credit (LC) may be more suitable where payment is normally made outside the credit and the bank is required only upon default, or where Original Bills of Lading (B/Ls) cannot be presented promptly.

The parties should consider issuing-bank quality, confirming-bank cost, recourse, governing law, place of payment, documentary availability, resale arrangements, shipment duration, electronic presentation, and the effect of insolvency.

Credit terminology should never replace clear drafting. The instrument must state exactly who undertakes to pay, when the obligation arises, whether payment is with or without recourse, what documents are required, and how reimbursement and disputes will be handled.

Core Principles of Documentary Credits

Several principles unite the different forms of credit. The bank’s undertaking is separate from the sale contract. Banks examine documents rather than goods. Payment depends on a complying presentation. Confirmation creates an additional independent obligation. Negotiation can transfer documentary or draft rights in exchange for value.

The Bill of Lading (B/L) remains especially important because it can provide evidence of shipment, rights under the carriage contract, and security through documentary control of the goods. Where a standby structure replaces the traditional Bill of Lading (B/L), the financing bank may lose that security and must rely more heavily on the buyer’s credit or collateral.

Documentary credits are therefore both payment mechanisms and risk-allocation systems. Their effectiveness depends on the alignment of the sale contract, credit terms, banking rules, shipping documents, and governing law.

A well-structured credit gives the seller dependable payment, the buyer documentary assurance, and the banks enforceable rights of reimbursement. Poorly coordinated terms can produce rejection, recourse, funding gaps, confidentiality breaches, or disputes across several jurisdictions.
