Definition
An indorsement in blank is an indorsement on a negotiable instrument — a check, promissory note, bill of exchange, or similar document — that consists of the indorser's signature alone, without naming any specific person as the transferee. Because no payee is designated, an instrument bearing a blank indorsement becomes payable to bearer: whoever physically holds it may enforce it or transfer it further by delivery alone, without any additional indorsement.
This stands in contrast to a special indorsement (also called an indorsement in full), which names a specific person to whom the instrument is payable, requiring that person's signature before the instrument can be further negotiated.

Common Language
Modern common usage (Wiktionary): "Indorsement" and "endorsement" are treated as variant spellings. In ordinary use, to endorse means to sign the back of a check before depositing or cashing it, or to publicly express support for a person or product.
Historical common usage (Webster's 1913): "Indorsement" — the act of writing on the back of a note, bill, or other written instrument; a writing on the back of a note or bill of exchange.
The everyday act of signing the back of a check before depositing it is, technically, an indorsement in blank — most people do not realize they are converting a negotiable instrument to bearer paper, with all the transfer and enforcement consequences that follow. The legal significance goes well beyond the mechanical act of signing.

Common Confusion
INDORSEMENT IN BLANK vs. SPECIAL INDORSEMENT: These are the two primary categories of indorsement under negotiable instruments law, and conflating them produces real legal consequences. A blank indorsement creates bearer paper; a special indorsement preserves order-paper status and restricts negotiation to the named transferee. A holder can convert a blank indorsement to a special one by writing in a payee's name above the signature, but the reverse is not possible without the indorser's cooperation.
INDORSEMENT IN BLANK vs. RESTRICTIVE INDORSEMENT: A restrictive indorsement (e.g., "For deposit only") limits how the instrument may be used. An indorsement in blank imposes no restrictions. The two concepts are orthogonal: an indorsement may be blank as to payee while still carrying a restrictive legend, though in practice a pure blank indorsement carries neither a named payee nor a limiting condition.

Why It Matters in Research
The legal effect of a blank indorsement — transforming order paper into bearer paper — is the central research issue. Under UCC Article 3 (§ 3-205), this transformation is explicit and its consequences for holder-in-due-course status, theft exposure, and enforcement rights are well-developed in modern case law. Researchers working in pre-UCC materials will find the same operative distinction, but the vocabulary is less standardized: sources may speak of "general indorsement," "blank indorsement," or "indorsement in blank" interchangeably, while "special indorsement" may be rendered as "full indorsement" or "indorsement in full."
Historical treatise sources and the older English cases that informed American commercial law often framed the blank/special distinction in terms of the Law Merchant rather than any codifying statute. Researchers should be alert to this when tracing doctrinal lineage through nineteenth-century American authorities, where the NIL (Negotiable Instruments Law, the pre-UCC uniform act) provides an intermediate reference point.
A practical trap in historical sources: older materials sometimes use "blank indorsement" loosely to mean any indorsement made without condition, not strictly one without a named payee. Context — and whether the source predates the NIL — governs which sense is meant.
Corpus connections are significant. Questions about holder-in-due-course status almost always turn on whether the instrument was bearer paper or order paper at the moment of transfer, making indorsement in blank a gateway concept for a wide range of commercial law disputes. Researchers in negotiable instruments cases should confirm, as a threshold matter, the form of any indorsement in the chain of title.

Historical Dictionary Support
Rapalje & Lawrence define indorsement in blank as an indorsement "consisting merely of the indorser's name written on the back of the instrument, without any direction as to the person to whom it is to be paid." They distinguish it from a special indorsement, which names the transferee, and note the bearer-paper consequence directly: a blank indorsement makes the instrument "payable to bearer, and transferable by delivery." This core formulation has remained stable across more than a century of American law and carries through intact into UCC Article 3.
Rapalje & Lawrence treat the blank/special distinction as fundamental and well-settled, reflecting its deep roots in the Law Merchant. What the historical dictionaries do not address is the interplay between indorsement form and holder-in-due-course doctrine as that doctrine was elaborated under the NIL and later the UCC — a doctrinal development that significantly expanded the practical stakes of the distinction for modern researchers.

Jurisdictional Note
All U.S. jurisdictions have adopted UCC Article 3, which governs indorsement in blank under § 3-205. The operative rule — blank indorsement creates bearer paper, transferable by delivery — is uniform. Minor variations may exist in state-specific amendments to Article 3, but they do not disturb the core blank/special distinction.
