Definition
Animal skin — typically sheep, goat, or calf — prepared and dressed for use as a writing surface. In legal contexts, parchment was the standard material for formal legal instruments across centuries of common law practice. Deeds, charters, royal writs, judicial records, and government commissions were routinely engrossed on parchment because of its durability and resistance to alteration relative to paper. In England, writs of summons were issued on parchment until the Judicature Act 1875 formally ended the requirement. Though now largely ceremonial or archaic, parchment retains symbolic presence in formal legal instruments and some official government documents.
Common Language
Modern common usage (Wiktionary): Animal skin prepared as a writing surface; a document written on such material; a diploma; stiff paper imitating that material; a creamy tan color.
Historical common usage (Webster's 1913): The skin of a lamb, sheep, goat, young calf, or other animal, prepared for writing on.
The common and legal meanings here are close, but the legal significance is narrower: in legal sources, parchment is not merely a material but a marker of documentary formality and evidentiary weight. A researcher encountering "parchment" in a legal instrument or court record should read it as a signal of legal solemnity — the choice of material was a deliberate act carrying implications for authenticity and permanence, not merely a practical writing decision.
Why It Matters in Research
Researchers working in pre-modern or early modern legal materials will encounter parchment not as incidental background but as a functional legal fact. The material on which an instrument was written could bear on its authenticity, formality, and enforceability. When reviewing transcriptions of early deeds, writs, or royal grants, understanding that the original was on parchment helps explain why copying practices, endorsements, and preservation notes appear as they do in the record.
The Judicature Act 1875 is a hard dividing line for English legal history: writs of summons before that date were parchment instruments; afterward, paper became standard. If a researcher is dating an undated English writ or tracing procedural history, this shift is a useful terminus post quem / ante quem marker.
In American legal history, parchment persisted longer in ceremonial and official instruments — land patents, enrolled acts of Congress, and state charters — than in ordinary conveyancing, where paper displaced it earlier. Researchers consulting colonial-era land records should not assume that "parchment" and "deed" are interchangeable terms in indexes: some archives catalog by material type, and a document cataloged as a "parchment" may be a grant, charter, or patent rather than an ordinary conveyance.
Researchers should also be alert to the term "vellum," which appears alongside parchment in many sources and is sometimes treated as synonymous. In strict usage, vellum is made from calf skin prepared differently and is of finer quality than ordinary parchment, but the terms were used interchangeably in many legal and archival contexts.
Historical Dictionary Support
The historical dictionaries are notably brief and in substantial agreement on the core definition. Black's (both editions), Rapalje & Lawrence, and Bouvier all converge on the sheep-skin / Pergamus origin account and the English writ practice abolished by the Judicature Act 1875 — suggesting these sources are drawing from the same stream (Wharton's Law Lexicon is explicitly cited in Black's and Bouvier).
Rapalje & Lawrence adds a historical detail the others omit: the origin story attributing parchment's invention to King Eumenes of Pergamus, who developed the material after Ptolemy of Egypt prohibited the export of papyrus into Asia. While this is an ancient account of disputed historical accuracy, its presence in a legal dictionary reflects how 19th-century legal lexicographers understood the term's provenance and considered it worth transmitting to practitioners.
Anderson's is the most practically oriented of the group, framing parchment in terms of its evidentiary and governmental functions — preserving evidence of grants, commissions, judicial records, and private conveyances — rather than its material origin. This is the entry that comes closest to capturing why the word appears in legal dictionaries at all.
What all five sources miss: any treatment of parchment's role in American legal practice, the transition from parchment to paper in colonial and early federal records, or the archival and authentication issues that arise when assessing parchment originals versus paper copies. The entries are essentially historical footnotes rather than working research tools.
Jurisdictional Note
English law provides the clearest doctrinal history, with the Judicature Act 1875 marking the formal end of compulsory parchment for writs. American jurisdictions never uniformly mandated parchment for private instruments, though official government documents — particularly federal and state land patents — continued parchment use well into the 19th century. Researchers working with civil law jurisdictions will find parchment less significant as a legal category, as the documentary traditions differ.
