Definition
"In blank" describes an indorsement on a negotiable instrument — typically a promissory note, bill of exchange, or check — where the indorser signs only their name without designating a specific person to whom the instrument is transferred. An indorsement in blank converts the instrument into bearer paper: whoever holds it may negotiate it further, simply by delivery, without any additional indorsement.
The phrase can also apply more broadly to any legal instrument or document left partially incomplete — with spaces unfilled — at the time of signing, with the expectation or authority (express or implied) that blanks will be completed later. In negotiable instruments law, however, "in blank" has the specific, technical meaning described above.
Common Language
Modern common usage (Wiktionary): "In blank" is not a standard entry in contemporary general dictionaries. In ordinary English, "blank" refers to an empty or unfilled space, and "in blank" would naturally be read as meaning "left empty" or "without content."
Historical common usage (Webster's 1913): Webster's 1913 defines "blank" as "an empty space, or a space left empty; a void; a vacancy" and also as "a paper unwritten; a paper without marks or characters."
The gap between common and legal meaning is subtle but consequential. In ordinary usage, "in blank" suggests incompleteness — something missing or overlooked. In law, an indorsement in blank is not incomplete at all; it is a fully operative legal act with deliberate and significant consequences, transforming a named-party instrument into freely transferable bearer paper. A researcher reading "indorsed in blank" should not interpret it as a defect or an error of omission.
Common Confusion
"In blank" is easily confused with "blank instrument" (a document signed before all material terms are filled in) and with "restrictive indorsement" (which names a specific indorsee or limits the instrument's use). These are distinct concepts. A blank instrument concerns the completeness of the document's terms at execution; an indorsement in blank concerns only the absence of a named transferee on an otherwise complete instrument. Conflating them produces errors in analyzing both the validity and the negotiability of instruments in historical records.
Why It Matters in Research
The practical stakes of "in blank" shift considerably across time. In nineteenth-century commercial law sources, the term is almost exclusively tied to the law of bills and notes, and researchers should treat it as a term of art within that narrow domain. By the twentieth century, the Uniform Negotiable Instruments Law and later the Uniform Commercial Code (Article 3) codified blank indorsement doctrine, and the phrase "indorsement in blank" appears in statutory and case law with a more precise, stable meaning than it carried in common law sources.
Several research traps apply. First, older sources — including all four historical dictionaries here — cite Stephens's Commentaries (2 Steph. Comm. 164) as the authority. Researchers relying solely on these definitions are working from a secondary English treatise, not from American statutory or case authority. Second, "in blank" occasionally appears in historical deed and conveyancing records to describe instruments signed with spaces left for grantee names or consideration amounts, a usage analytically distinct from negotiable instruments law. Context is essential. Third, the legal consequence of a blank indorsement — that delivery alone suffices to negotiate the instrument — carries implications for chain-of-title and fraud analysis that researchers examining commercial disputes, bank records, or estate inventories should track carefully.
Historical Dictionary Support
All four historical sources agree on the core definition: "in blank" means an indorsement consisting solely of the indorser's name, without restriction to a named indorsee. Black's (both editions) and Burrill's track each other closely, each citing 2 Steph. Comm. 164. Bouvier's is the most succinct, glossing the term as "without restriction" and noting the absence of a named indorsee.
Burrill adds one useful observation the others omit: the term derives from the blank space physically left above the indorser's signature — the space that would have been filled by a specific indorsee's name in a special indorsement. This physical description is genuinely helpful for researchers reading manuscript commercial records, where the visual layout of an instrument may itself signal its legal character.
None of the historical sources address the downstream negotiation mechanics in detail — they do not explain that a blank indorsement makes the instrument payable to bearer or that a holder may convert it to a special indorsement by writing above the signature. Researchers need to supplement these dictionary entries with treatise or statutory sources for a full functional picture.
Jurisdictional Note
The mechanics of blank indorsement are substantially uniform across American jurisdictions through the influence of the Uniform Negotiable Instruments Law (adopted widely by the early twentieth century) and later UCC Article 3. Variations in historical common law treatment existed before uniform acts, and researchers working with pre-codification sources should account for state-specific case law.
