Definition
A letter of advice is a written communication from one party to another informing the recipient of an action taken or about to be taken by the writer that will affect the recipient's interests or obligations. The writer discloses facts already unknown to the recipient — typically details of a commercial transaction — so that the recipient can act accordingly.
The term carries two related but distinct applications:
1. Commercial/banking usage: A notice sent by a drawer of a bill of exchange to the drawee, informing the drawee that a bill has been drawn on them, the amount, and the terms. This alerts the drawee to expect the bill and allows them to verify its authenticity before honoring it.
2. General commercial usage: Any formal written notice from a seller, shipper, or agent to a buyer, consignee, or counterparty advising that goods have been shipped, payment has been arranged, or some other transaction-related event has occurred.

Common Language
Modern common usage (Wiktionary): A formal letter informing someone of an event or action that has occurred; specifically, a letter notifying a purchaser that goods have been shipped.
Historical common usage (Webster's 1913): Not separately defined; "advice" in the commercial sense meant "intelligence" or "notice" — particularly news of a business transaction communicated between merchants at a distance.
The gap between common and legal meaning here is narrow but worth noting. In ordinary usage, a letter of advice is essentially any informational notice. In legal and commercial practice, the term carries a more specific transactional function: it is a deliberate act with legal consequences, particularly in negotiable instruments law, where the failure to send or receive a proper letter of advice can bear on questions of fraud, alteration, and the drawee's duty to honor or dishonor a bill.

Why It Matters in Research
Researchers encounter this term most often in two bodies of material: negotiable instruments cases and older merchant law treatises. Its significance has shifted considerably across time.
In historical sources — particularly 18th- and 19th-century commercial law — the letter of advice was a practical cornerstone of bill-of-exchange transactions. Merchants routinely sent letters of advice when drawing bills on distant correspondents, and courts recognized that the absence of such a letter could indicate fraud or forgery. Researchers consulting older case reporters or equity decisions should understand that the letter of advice was often legally operative: it could affect the drawee's liability and served as evidence of the parties' intent.
In modern commercial law, the function of the letter of advice has been largely absorbed into documentary and electronic transaction frameworks. The term appears infrequently in contemporary statutes and is essentially absent from the UCC by name, though its underlying purpose — giving prior notice of a transaction — survives in concepts like remittance advices, shipping notices, and SWIFT payment messages in international banking. Researchers searching modern databases for this term will find thin results and should use broader commercial notice terminology to locate relevant doctrine.
A trap in historical sources: some older dictionaries and treatises use "letter of advice" and "letter of credit" in close proximity, and the two are sometimes confused in historical judicial opinions. They are distinct instruments. A letter of credit is an undertaking to pay; a letter of advice is a notice of fact. When reading historical commercial cases, verify which instrument is actually at issue before relying on the court's characterization.
The term also appears occasionally in agency and factor law, where a principal advises a correspondent or factor of instructions or shipments. Context is essential — the same phrase can denote a notice of shipped goods, a notice of a drawn bill, or a general advisory letter from principal to agent, depending on the transaction.

Historical Dictionary Support
The three shelf sources agree on the core definition — a letter informing the recipient of facts or acts unknown to them, typically related to a commercial transaction — but differ in emphasis.
Bouvier's is the most substantive, explicitly situating the letter of advice in the bill-of-exchange context and noting its dual protective purpose: preventing fraud and alerting the drawee to what provision has been made for payment. This reflects the instrument's practical commercial importance in the era when Bouvier's was compiled.
Rapalje & Lawrence is the most spare, defining the letter by its informational function without anchoring it to any particular transaction type. Their cross-reference to "ADVICE" signals that the term draws meaning from the broader commercial law of merchant correspondence.
Black's adds the element of warning — "advising or warning the latter of something which he ought to know" — and emphasizes that the act disclosed is one that "will ultimately affect the recipient." This framing is slightly broader than the others and encompasses letters beyond the bill-of-exchange context.
None of the three historical sources addresses the term's decline in modern practice or its relationship to contemporary payment systems. Researchers should not assume that the commercial importance these sources attach to the term translates to modern legal significance without independent verification.

Jurisdictional Note
No significant modern jurisdictional variation exists for this term as a formal legal concept, because it has receded from active statutory use in most common law jurisdictions. Its historical significance was greatest in English and American merchant law; researchers working with civil law jurisdiction materials should note that functional equivalents exist under different nomenclature.
