Definition
Acceptance au besoin (from French, "in case of need") is a form of contingent acceptance of a bill of exchange, made by a designated third party who steps in to accept the instrument only if the original drawee refuses or fails to accept it. The party named au besoin functions as a fallback acceptor, preserving the bill's negotiability and protecting the holder from immediate dishonor. The arrangement is typically noted on the face of the bill itself at the time of drafting, identifying the recourse party in advance.
Common Language
This term has no meaningful common-language counterpart. "Au besoin" is standard French for "if needed" or "in case of need," and the phrase appears in English primarily as legal or commercial jargon inherited from French mercantile law. Researchers encountering the term in historical commercial documents should treat it as a term of art, not translate it literally and move on.
Core Elements
For a valid acceptance au besoin, three components are typically present:
1. A bill of exchange drawn on a primary drawee in the ordinary manner.
2. A designated recourse party (the besoin acceptor) named on the bill, to whom the holder may resort if the drawee declines acceptance.
3. Contingency — the besoin acceptor's obligation is triggered only by the refusal or failure of the original drawee, not by mere holder preference.
The contingent nature is the defining feature. A besoin acceptor has no obligation until the primary drawee's default is established.
Why It Matters in Research
Researchers working in commercial law history, bills of exchange, or negotiable instruments will encounter this term most frequently in treatises and cases from the eighteenth and nineteenth centuries, when French commercial law concepts were actively absorbed into Anglo-American mercantile practice. The term appears almost exclusively in that historical register; modern American UCC-based commercial law does not use this terminology, having rationalized the law of negotiable instruments without reference to French-derived nomenclature.
The key research trap: this term looks like an acceptance (the standard act of a drawee agreeing to pay a bill) but it is not an unconditional acceptance. It is a conditional, secondary acceptance. Conflating it with a standard acceptance will misread the liability structure of the instrument entirely. In historical cases involving bills with multiple parties, identifying which acceptances are au besoin and which are primary is essential to tracing the order of liability.
Story's work on bills (referenced uniformly across all three source dictionaries) is the authoritative treatise link for this concept in the American historical corpus. Researchers should consult Joseph Story, Commentaries on the Law of Bills of Exchange (various editions, 1843 onward) at the sections cited to understand the full doctrinal context, including how American courts treated the rights of holders against besoin acceptors and the procedural requirements for triggering that contingent liability.
Jurisdictional note: this concept originates in French commercial law and was most fully developed in the civil law tradition. Its appearance in common law sources reflects the transnational character of mercantile law in the eighteenth and nineteenth centuries. It is not a recognized category under the Uniform Commercial Code and will not appear in modern American statutory treatment of negotiable instruments.
Historical Dictionary Support
All three source dictionaries — Black's (1st and 2nd editions) and Burrill's — provide virtually identical entries, each tracing directly to Story on Bills. The unanimity signals that compilers were drawing from the same treatise tradition rather than from independent judicial or statutory development. None of the entries elaborates on the procedural mechanics of triggering the besoin acceptor's liability, the notice requirements, or the holder's rights on dishonor — gaps that researchers must fill from Story directly or from contemporaneous French commercial codes. The 2nd edition of Black's contains a minor typographical artifact ("Dill" for "bill" and "$§" for "§§") reflecting reproduction error, not substantive change. No meaningful doctrinal evolution appears across the three entries.
