Documentary credit in international sales: a key tool for securing your payments

In international trade, payment is often the greatest challenge. Geographic distance, unfamiliarity between business partners, currency fluctuations, political risks, and the diversity of legal systems all increase uncertainty, particularly when payment is involved. Whether you are exporter or importer, one essential question remains: how can payments be secured without blocking the transaction? It is precisely in this context that the Documentary Credit (or Letter of Credit) emerges as a particularly effective solution.

Why and how?

The documentary credit is one of the most reliable payment instruments (1) in international trade. It establishes a secure mechanism in which the seller (exporter) is assured of payment once the goods have been shipped, while the buyer (importer) only pays after receiving documentary evidence confirming that the shipment has been properly executed. Simply, a bank undertakes to pay the seller provided that the documents presented strictly comply with the terms and conditions of the credit. This mechanism significantly reduces uncertainty, strengthens trust between trading partners, and reconciles the sometimes divergent interests of the parties.

A documentary credit may therefore be defined as the irrevocable undertaking by a bank, acting on behalf of its client-buyer to pay the seller against presentation of documents strictly complying with the terms and conditions of the credit, independently of the underlying contract of sale.

The effectiveness of this mechanism is primarily based on two fundamental principles: the autonomy principle of the documentary credit and the principle of strict documentary compliance.

But how are these two fundamental principles applied in practice?

I. The Principle of Autonomy of the Documentary Credit

A. Independence from the Contract of Sale: “Banks Deal with Documents and Not with Goods”

The autonomy principle is based on the idea that documentary credit constitutes a legally distinct and independent undertaking from the underlying international sales contract. It is a commitment undertaken by the banks themselves, separate from the contractual relationship between buyer and seller. In practice, the buyer’s bank merely verifies whether the documents required under the credit comply with its terms, without assessing the actual performance of the commercial contract. In other words, the bank’s examination concerns only the documents and not the underlying economic transaction.

This principle is expressly enshrined in the Uniform Customs and Practice for Documentary Credits (UCP 600) published by the International Chamber of Commerce, notably in Articles 3 and 5, which provide that “Credits, by their nature, are separate transactions from the sales or other contracts on which they may be based…”3 and that “Banks deal with documents and not with goods, services or performance to which the documents may relate.”5

French case law consistently confirms this principle of autonomy by stating that “the bank’s obligation must be assessed solely in light of documentary compliance, independently of disputes relating to the contract of sale.” — French Court of Cassation, Commercial Chamber, 17 December 2013, No. 12-25.151. In this case, the Court upheld payment made by the buyer’s bank on the grounds that documents presented were compliant, despite buyer’s allegations concerning non-delivery, suspicions of fraud, and alleged documentary inconsistencies.

In another judgment , French Court of Cassation confirmed an appellate ruling by holding that “the issuing bank, having undertaken a direct and irrevocable obligation toward the seller, was required to honor its commitments regardless of the relationships existing between the applicant and the beneficiary…” — French Court of Cassation, Commercial Chamber, 14 March 1984, No. 82-10.522 (Bull. civ. IV, No. 101).

The autonomy principle therefore deprives the applicant of any right of interference: the applicant may neither compel the bank to pay when the documents are irregular, nor prevent payment when the documents comply with the terms of the credit. Accordingly, the Paris Court of Appeal, overturning a judgment of the Commercial Court, rightly held that “a bank was entitled to reject irregular documents and refuse payment independently of the applicant’s position,” even though the latter requested payment despite the irregularities — Paris Court of Appeal, 14th Chamber A, 6 February 2002, Banque Hervé v Société Gyl Bagages, Juris-Data No. 221336.

This principle clearly demonstrates that a bank does not pay for goods, but for documents complying with the terms of the credit.

B. Consequence of the Autonomy Principle: The unforceability of Defenses, or Why the Buyer Cannot Block Payment

One of the main consequences of the autonomy principle is the unforceability of defenses. Under this rule, the buyer (applicant) cannot prevent payment under documentary credit by alleging defective performance of the sales contract or non-conformity of the goods. Disputes relating to commercial contract have no impact on the bank’s payment obligation, provided that the documents presented strictly comply with the conditions of the credit. This principle was reaffirmed in the above-mentioned decision of 17 December 2013.

Ultimately, while the autonomy principle guarantees essential security for the exporter-seller by ensuring payment, it may conversely weaken the buyer’s position, insofar as the buyer cannot raise defenses arising from the sales contract against the bank.

II. The Principle of Strict Documentary Compliance

A. Precision Is Essential

The documentary credit system operates under a zero-tolerance approach. Every detail matters: dates must match, quantities must match, the description of the goods must match, Incoterms and carriage conditions must match, the onboard loading date must match, and so forth. In practice, issuing banks exercise extreme vigilance in examining documents against the requirements of the credit, as their liability may be engaged. The slightest discrepancy may result in refusal of payment.

The decision to honor or refuse payment therefore places the issuing bank in a delicate position regarding liability. When the documents strictly comply with the terms of the credit, the bank is obliged to honor payment, and any unjustified refusal may engage its liability. Conversely, when the documents contain irregularities, even minor ones, the bank must reject them, regardless of whether the goods conform to the underlying sales contract. In both situations, the bank is deemed to have properly performed its role and should not incur liability.

However, the bank may incur liability if it fails to fulfill its duty of vigilance in examining the documents. The French Court of Cassation held that “a bank incurs liability when it makes payment despite apparent irregularities without the applicant’s consent.” — French Court of Cassation, Commercial Chamber, 7 January 2004, No. 01-02.572 (Bull. civ. IV, No. 1). When the documents presented do not strictly comply with the terms of the irrevocable credit, the bank is obliged to refuse payment, unless the applicant expressly authorizes the bank to waive the discrepancies.

B. The Exception of Proven Fraud: A Strictly Limited Exception to the Autonomy Principle

Documentary fraud constitutes the principal exception to the autonomy principle of documentary credit. Banks may refuse payment, but only where the fraud is manifest and clearly established. Mere suspicion is insufficient.

In the aforementioned decision of 17 December 2013, No. 12-25.151, the French Court of Cassation upheld payment under the documentary credit despite suspicions surrounding the transaction, on the grounds that proof of manifest fraud had not been established. This decision illustrates the Court’s intention to preserve the security and effectiveness of the documentary credit mechanism by reaffirming the primacy of documentary examination and the autonomy of the credit from the underlying commercial contract.

In another case, however, the Court upheld refusal of payment because of proven fraud in the transaction. The documents presented falsely indicated a quantity of goods greater than that actually shipped. Since the fraud originated from the beneficiary of the documentary credit, the Court held that such fraud barred execution of the documentary credit. — French Court of Cassation, Commercial Chamber, 7 April 1987, No. 85-17.399 (Bull. civ. IV).

English law adopts a similar approach by requiring that the fraud be attributable to the beneficiary. The House of Lords thus held that “the bank may refuse payment only if the fraud is attributable to the beneficiary himself.” — House of Lords, United City Merchants v Royal Bank of Canada, [1983] 1 AC 168. Accordingly, the presentation of forged documents by a third party does not justify refusal of payment where the beneficiary acted in good faith. In that case, the bill of lading had been falsified by a freight forwarder without the beneficiary’s involvement, which led the English court to order payment.

This position therefore reinforces the protection afforded to beneficiaries acting in good faith. Nevertheless, fraud attributable to the beneficiary must be proven before payment may be refused.

What This Means for Your Business ?

The documentary credit is an extremely powerful tool, but also a highly technical and legal mechanism. When properly used, it allows businesses to :

Secure international payments,
Reduce commercial and financial risks,
Strengthen trust with new business partners,
Structure safer export-import operations.

Conversely, improper use may lead to :

Payment delays,
Refusal of payment,
Costly disputes.

Key Takeaways
