Definition
A writing, document, or signature made by a person other than any of the parties to the instrument. The term stands in direct opposition to autograph, which denotes a document written or signed by the party themselves. In legal usage, an allograph is most commonly encountered in the law of documents and authentication: a secretary who signs a contract on behalf of a principal, or a notary who writes out a will dictated by the testator, produces an allograph.
The concept carries practical weight in questions of execution and authentication. Whether a document is an allograph or autograph can bear on its validity, the standard of proof required to authenticate it, and the formalities the law demands before it will be given legal effect.

Common Language
Modern common usage (Wiktionary): In general linguistics, "allograph" most commonly means a variant form of a letter or other grapheme — the different shapes that a single letter can take (print versus cursive "a," for instance). A secondary, less-common meaning captures the legal sense: a signature made by one person for another.
Historical common usage (Webster's 1913): "A writing or signature made by some person other than any of the parties thereto; — opposed to autograph."
The linguistic meaning (a grapheme variant) is the dominant sense in modern general usage and is entirely unrelated to the legal sense. A researcher encountering "allograph" in a general reference work or linguistics text is reading about letterforms, not document execution. The legal sense — third-party authorship of a legal instrument — is the exclusive meaning in the law dictionary tradition.

Why It Matters in Research
This term is a minor but precise term of art in the law of documents, wills, and authentication. Researchers will encounter it most often in:
**Wills and testamentary formalities.** Many jurisdictions historically required wills to be in the testator's own hand (holographic wills) or, if allographic, to meet specific attestation requirements. Understanding the allograph/autograph distinction is essential when working with historical probate records and treatises on testamentary execution. A will described as allographic in older sources signals a document written by a scribe or attorney, not the testator, and triggers a different set of formal requirements.
**Document authentication disputes.** In evidence and authentication questions, whether a signature is allographic — made by an authorized agent rather than the principal — determines which authentication rules apply and what agency authority must be proved. Historical cases involving commercial instruments and agency frequently turn on this distinction without using the word "allograph" explicitly, so researchers should recognize the concept even when the term is absent.
**Thin coverage in later sources.** The term largely disappeared from routine legal vocabulary after the mid-twentieth century. Researchers working in modern secondary sources may find it absent or only briefly noted, even in comprehensive dictionaries. Its absence from later editions of standard references does not mean the underlying concept is obsolete — it has simply been absorbed into broader discussions of authentication, agency, and testamentary formality.
**Corpus navigation.** In the Law Mind corpus, allograph appears in document-execution and evidence contexts. Follow connections to autograph, holograph, and attestation to locate the full doctrinal neighborhood.

Historical Dictionary Support
Black's Law Dictionary (both the standard edition and the second edition) give identical, terse definitions: "A document not written by any of the parties thereto; opposed to autograph." Webster's 1913 tracks the same meaning almost word for word. There is complete agreement across sources — no divergence, no evolution visible between the two Black's editions. The definition is stable precisely because the term is narrow and technical.
What the historical sources do not supply: any analysis of how the allographic character of a document affects its legal consequences. The dictionaries define the term but leave the legal work — the rules of authentication, the testamentary formalities that distinguish allographic from holographic wills, the agency principles governing allographic signatures — to treatises and case law. Researchers should treat the dictionary entry as a threshold identification, not a doctrinal guide.
The Wiktionary addition of the linguistics sense (grapheme variant) post-dates the legal dictionary tradition and reflects a shift in the term's primary home from law to linguistics. Historical legal sources uniformly use the term in the document-execution sense only.
