Definition
Divided into many or several parts. In legal usage, the term describes a document, agreement, or instrument that is executed in multiple corresponding parts or that involves more than two parties. A bipartite instrument has two parts; a multipartite instrument has three or more.
The term appears most frequently in the context of deeds and contracts. A multipartite indenture, for example, is one drawn up in as many duplicate originals as there are parties to the agreement, each party retaining one part. The number of parts was historically significant: the physical correspondence of the cut or indented edges confirmed authenticity and completeness.

Common Language
Modern common usage (Wiktionary): Divided into multiple parts; involving multiple nations or political parties; in physics, describing a system of three or more quantum states.
Historical common usage (Webster's 1913): Divided into many parts; having several parts.
The common meaning is descriptively accurate but misses the legal function. In law, "multipartite" does not merely describe the internal structure of a single document — it describes the formal arrangement by which multiple counterparts are produced, one for each party. The distinction between "having several parts" (common) and "executed in several corresponding parts, each constituting an original" (legal) is consequential when authenticating historical instruments.

Why It Matters in Research
Researchers encountering "multipartite" in historical deed books, conveyancing manuals, or chancery records should understand that the term signals something about documentary form, not just content. In pre-modern practice, the number of parts in a deed was often recited in the opening language ("This indenture, made in three parts..."), and "multipartite" is the generic descriptor for any such instrument with more than two parts.
Two traps appear in historical sources. First, the term is relatively rare in case law and statutory text; researchers may find it more frequently in treatise literature and form books than in judicial opinions. Its absence from the headnotes of a case does not mean the concept is absent — look instead for "indenture," "tripartite deed," or recital language counting the parts.
Second, the Rapalje & Lawrence entry places "multipartite" adjacent to "multiplepoinding," the Scottish interpleader procedure. These are unrelated terms and the proximity is purely alphabetical, but researchers scanning the page should not conflate them. Multiplepoinding is a distinct procedural device; multipartite is purely a descriptor of documentary form.
For corpus researchers working in real property, conveyancing history, or treaty law, multipartite instruments require attention to which physical part is being examined. In historical collections, only one part of a multipartite deed may survive, and that surviving part may or may not bear all parties' signatures or seals.
In international law, "multipartite" functions as a near-synonym for "multilateral" when describing treaties involving three or more sovereign parties, though modern practice strongly favors "multilateral" in that context.

Historical Dictionary Support
The three historical sources are in complete agreement: multipartite means divided into many or several parts. There is no divergence, no evolution, and no controversy in the historical record on this point. Black's 1st and 2nd editions give identical one-line entries. Rapalje & Lawrence is equally terse.
What the historical dictionaries collectively fail to address is the practical significance of the term in conveyancing — the reason it existed as a legal term of art rather than a purely descriptive adjective. That context must be supplied from conveyancing treatises (Sheppard's Touchstone, Blackstone's Commentaries on the indenture form) rather than from the dictionary shelf. The historical dictionaries treat the term as self-evident, which it largely is — but the researcher benefits from understanding why a deed was drawn in multiple parts at all.

Jurisdictional Note
In American practice, the formal multipartite indenture as a distinct documentary category largely disappeared as conveyancing practice simplified after the nineteenth century. The concept survives most visibly in international treaty practice and in complex commercial transactions involving three or more distinct parties, where "multipartite agreement" appears in transactional drafting as descriptive shorthand rather than as a term of art with independent legal consequences.
