Definition
A Latin term from the civil law meaning "deceased" or "dead." Used in legal instruments, pleadings, and records to denote a person who has died. The term functions both as an adjective (describing a deceased individual) and as a nominal form identifying a deceased person as a subject of legal interest — most commonly in matters of succession, probate, and status.
The phrase *defunctus sine prole* — dead without issue — appears frequently in instruments of conveyance, wills, and entail provisions, and carries specific operative significance: it typically triggers a remainder, reversion, or substitutionary gift that depends on the subject dying without surviving descendants.

Common Language
Modern common usage (Wiktionary): "Defunctus" has no standard entry in modern English dictionaries as a standalone word. Its anglicized form, "defunct," means no longer active, operative, or in existence — applied to organizations, laws, or things, not typically to persons.
Historical common usage (Webster's 1913): "Defunct" — dead; deceased; as, a defunct person. Also used colloquially for anything that has ceased to function.
The gap between the common and legal uses is subtle but consequential. Ordinary English uses "defunct" loosely and metaphorically — a defunct company, a defunct statute. The legal term *defunctus* is precise and personal: it refers exclusively to a deceased human being whose legal relationships, rights, and obligations are now subject to succession or administration. A researcher encountering *defunctus* in a historical instrument should not read it as general commentary on inoperability — it is a technical designation of death with substantive legal consequences.

Why It Matters in Research
*Defunctus* appears most often in three contexts within the Law Mind corpus: (1) civil law treatises and digests discussing the legal consequences of death, particularly the transmission of rights and obligations; (2) conveyancing instruments using *defunctus sine prole* or similar constructions to define contingent interests; and (3) probate and succession records in jurisdictions with civilian influence — Louisiana, Quebec, and early Spanish and French colonial territories — where Latin terminology from the Digest and Code survived longer in formal practice.
The primary research trap is treating *defunctus* as interchangeable with any synonym for "deceased." In civil law sources drawing on Justinian's Digest, *defunctus* carries the specific connotation of a person *quia vitâ defunctus est* — one who has "completed life" — which connects to the Roman concept of civil death and the precise moment at which succession rights vest. Burrill's citation to Dig. 40.15 and Cod. 7.21 points researchers toward Roman manumission and status law, where the timing of death relative to testamentary acts was legally critical.
For researchers working with entail instruments or fee tail constructions, *defunctus sine prole* is a term of art requiring careful attention to whether "issue" means issue living at the time of death or issue ever born. This distinction drove significant litigation in English and American property law. Historical sources will not always flag this ambiguity.
*Defunctus* also surfaces in ecclesiastical and canon law records, particularly in probate jurisdiction disputes between church and civil courts. Researchers in those collections should be alert to shifts in how the term is applied across jurisdictional boundaries.

Historical Dictionary Support
Burrill and Black are in agreement on the core definition but illuminate different aspects of the term's use. Burrill grounds *defunctus* in its civilian context with citations to the Digest and Code, and supplies the explanatory gloss *quia vitâ defunctus est* — "because he has completed life" — which reflects the Roman juristic understanding of death as a legal event rather than merely a biological one. This framing is useful for researchers working with civil law sources who need to understand why the term appears in texts dealing with manumission, testaments, and personal status.
Black's entry is spare by comparison, but the inclusion of *defunctus sine prole* as the primary illustrative phrase signals where the term does real work in common law practice. The phrase's importance in property instruments means Black's practical orientation captures the term's most frequent appearance in Anglo-American legal records.
Neither dictionary engages with the procedural dimension: in historical practice, establishing that a party was *defunctus* — proving death and its timing — was itself a legal act with evidentiary requirements. Researchers working with historical court records may find that *defunctus* in a pleading or record signals not merely a biographical fact but a contested legal determination.
