UCC / CommercialLegal glossary term
Quick answer
Letter of credit usually means a bank’s promise to pay a seller upon presentation of agreed documents. In contracts, it matters because it shields the seller from buyer default. Before signing, check the documentary requirements and irrevocability clause.
Definitions
What is letter of credit?
Legal Definition
A letter of credit is a bank’s written promise to pay a seller once the buyer satisfies specified documentary conditions. It creates a primary, independent obligation for the bank, allowing the seller to collect funds without relying on the buyer’s credit. The most critical qualifier is whether the credit is revocable or irrevocable under UCC § 5-108.
Plain-English Translation
Think of a letter of credit like a hall pass that lets a kid leave class only after showing a teacher a signed note; the school guarantees the kid can go, not the kid’s parents.
Contract relevance
Why letter of credit matters in contracts

| Related term | Plain meaning | Main difference from letter of credit |
|---|---|---|
| Bank guarantee | A promise to pay if the obligor defaults | Unlike a letter of credit, it is secondary to the underlying contract |
| Standby letter of credit | Functions as a backup payment tool | Used for performance security rather than routine trade payment |
| Cash on delivery | Immediate payment upon receipt | Provides no independent bank commitment |
Missing or vague
If letter of credit is missing or vague
If the letter of credit clause is vague, parties may argue over which documents satisfy the bank. Disputes arise when the seller submits paperwork they believe is correct, but the bank rejects it. The buyer might claim the credit was never intended to be irrevocable. Such uncertainty can delay payment for weeks, harming cash flow. Courts often interpret ambiguous clauses against the drafter, typically the buyer.
