Definition
A purpart is a share or allotted portion of an estate formerly held in common, assigned to one of the parties upon partition. The term applies most specifically to the individual shares falling to coparceners — that is, co-heirs — when a jointly inherited estate is divided among them. Upon partition, each coparcener's distinct portion became her purpart: the specific tract or interest carved out and allocated to her alone, in severalty, in place of her undivided share in the whole.
The term is essentially a synonym of purparty, and the two spellings appear interchangeably in older English and American legal sources. Some authorities treat purpart as the older or variant form and purparty as the preferred spelling; in practice, the two are functionally identical.
Common Confusion
PURPART and PURPARTY are the same concept; neither has a distinct legal meaning separate from the other. Researchers encountering one form in a historical document should search for both spellings, as usage was inconsistent even within the same era and jurisdiction. Neither term should be confused with the broader concept of partition generally — purpart refers specifically to the resulting share allocated to an individual party after partition is complete, not to the process itself.
Why It Matters in Research
This term appears almost exclusively in historical sources dealing with English common law inheritance and partition of real property. By the late nineteenth century in American practice, the term had fallen largely out of use in statutory and judicial drafting, replaced by plain language such as "share," "portion," or simply "lot" in partition proceedings. Researchers working with colonial-era deeds, early American conveyancing records, chancery partition decrees, or English equity materials will encounter purpart and purparty with some regularity.
The inconsistent spelling is the principal research trap. Black's 2nd Edition begins its definition and then appears to continue with alternate spellings, suggesting the term was already regarded as archaic and variable at the time of that edition's publication. Anderson's entry is unhelpfully truncated in available sources and redirects to PART. Bouvier redirects to PURPARTY. A researcher who indexes only one spelling may miss relevant materials.
The term's connection to coparcenary is significant for jurisdictional and historical research: coparcenary as a distinct mode of co-ownership was a feature of English common law inheritance tied to real property descending to daughters in the absence of male heirs. American jurisdictions progressively abolished or absorbed coparcenary into tenancy in common, which is part of why purpart/purparty receded from active legal vocabulary in the United States. In jurisdictions that retained closer adherence to English common law forms longer — particularly in property records from the original colonies — the term persists further into the nineteenth century.
Researchers tracing title chains in early American conveyancing should recognize purpart as a technical term of art indicating that a parcel was separated from a larger estate by a partition proceeding among co-heirs, and that the instrument in question may be traceable back to a prior undivided inheritance.
Historical Dictionary Support
All three source dictionaries agree on the core meaning: a share of a formerly common estate allotted to a coparcener upon partition. There is no substantive disagreement among the sources on substance.
Black's 2nd Edition provides the most useful description, noting that the word was "anciently applied to the shares falling separately to coparceners upon a division or partition of the estate" and that variant spellings existed — the entry appears to trail off into the variant form "purparty." This confirms that Black's treated the term as a historical curiosity even in 1910, not a term of active modern practice.
Bouvier's directs the reader to purparty without independent elaboration, treating the two as equivalent. Anderson's entry is too fragmentary in the available text to add independent value, with the truncated content appearing to mix this entry with an adjacent one.
What the historical dictionaries collectively miss is any treatment of how the term functioned in actual partition proceedings — whether in chancery or at law — or how the allocation of purparts was recorded in deeds and court decrees. For that procedural context, researchers should consult treatises on real property and equity practice from the period rather than relying on dictionary definitions alone.
Jurisdictional Note
Purpart is a term of English common law origin and is most relevant to research in jurisdictions that followed English real property rules closely, including early American states. Because coparcenary was progressively replaced by tenancy in common in most U.S. jurisdictions, the term has minimal significance in modern American practice and virtually none in civil law jurisdictions.
