Definition
Departison is an archaic Anglo-French legal term meaning division or partition — the act of dividing property, typically land, among co-owners or co-heirs. The term appears in early English legal records and Year Book pleadings as a variant expression for what modern law calls partition: the formal separation of jointly or commonly held property into individually owned shares.
Why It Matters in Research
Researchers working in medieval English legal records, early plea rolls, or Year Book materials may encounter departison where a modern source would use partition or division. The term belongs to the Law French stratum of English legal vocabulary and was not carried forward into modern usage; it does not appear in standard modern legal dictionaries or statutory language. A researcher unfamiliar with the term could misread or overlook references to property division in early sources.
The primary research risk is failure to recognize departison as a functional synonym for partition when scanning pre-modern materials. Searches conducted only under modern terminology will miss references framed in Law French. Conversely, researchers who encounter the term in a Year Book citation — such as the reference in Yearb. P. 8 Edw. III. 17 noted by Burrill — should treat it as a direct pointer to partition doctrine and trace the concept forward through that line of authority.
Because the term belongs to Law French rather than Latin or Middle English, it also signals that the source material likely dates to the period when Law French was the operative language of English pleading, broadly the thirteenth through early seventeenth centuries. This has implications for source authentication and dating.
Historical Dictionary Support
Burrill's Law Dictionary offers the only dictionary treatment located in the Law Mind corpus. The entry is sparse — "L. Fr. Division; partition" — with a single Year Book citation as the sole authority. Burrill treats the term as straightforwardly synonymous with partition and makes no distinction between departison and related terms such as parcenary or allotment.
What Burrill does not address is any procedural or substantive nuance that might have attached to the term in its original context: whether departison described voluntary division among co-heirs, court-ordered partition, or both; whether it applied equally to real and personal property; or whether it carried technical requirements distinct from a simple agreement to divide. The Year Book citation itself — Yearb. P. 8 Edw. III. 17, placing the term in an Edward III pleading context from around 1334 — suggests it was live vocabulary in fourteenth-century practice, but the corpus of authority is too thin to reconstruct those distinctions from dictionary sources alone. Primary Year Book research would be required to recover any finer meaning.
No other historical dictionary in the Law Mind corpus appears to define departison independently. This is consistent with the term's narrow and archaic footprint; it was superseded by partition in both legal usage and common understanding well before the major English legal dictionaries of the early modern and modern periods were compiled.
Jurisdictional Note
Departison is specific to the English common law tradition and its Law French vocabulary. It has no recognized counterpart in civil law systems or in jurisdictions whose legal traditions did not descend from medieval English practice. Modern partition law in England, the United States, and related common law jurisdictions proceeds under the term partition.
