Definition
A Latin term from Roman and civil law denoting a legacy — a gift of property left by a deceased person through a will or testament, to be carried out by the heir. In its classical civil law sense, *legatum* describes any testamentary gift distinct from an inheritance (*hereditas*): where the heir receives the estate as a universal successor, a *legatum* carves out a specific benefit to be delivered by the heir to a named recipient (the legatee).
In old English ecclesiastical usage, the term carried a narrower sense: a legacy given to the church, or a customary mortuary payment — a gift made at death to the parish as a customary obligation rather than a purely voluntary bequest.
Two senses therefore coexist in the historical record:
1. *Civil law sense*: Any testamentary legacy; a gift by will to be satisfied by the heir out of the estate.
2. *English ecclesiastical sense*: A mortuary or church legacy; a prescribed or customary gift to the church at the time of death.

Recognized Forms
/SUBTYPES
Roman law developed a detailed taxonomy of *legata*, which appears in the Digest and Institutes and surfaces in civil law scholarship cited in historical English and American dictionaries:
- *Legatum per vindicationem*: A legacy that vested title directly in the legatee, who could assert a real action to recover it.
- *Legatum per damnationem*: A legacy imposing an obligation on the heir to convey the thing; the legatee held only a personal action.
- *Legatum sinendi modo*: A legacy requiring the heir to permit the legatee to take the thing.
- *Legatum per praeceptionem*: A legacy in advance, usually to one of several co-heirs.
These subtypes matter primarily for researchers working in Roman law texts, civil law jurisdictions, or early modern English equity sources that borrowed Roman concepts.

Why It Matters in Research
Researchers encounter *legatum* primarily in three contexts: (1) Roman law sources and civilian commentaries, (2) English ecclesiastical and canon law records, and (3) early American legal dictionaries and equity treatises that carried forward civilian vocabulary.
The key navigational challenge is distinguishing which sense applies. In a Roman law or civil law context, *legatum* is a broad technical term for any testamentary gift to a non-heir. In English ecclesiastical records — parish registers, probate inventories, visitation records — *legatum* often refers narrowly to customary church dues paid at death, distinct from a voluntarily bequeathed legacy. Conflating the two produces misreadings.
*Legatum* does not appear in modern American or English statutory law as an operative term; it has been wholly displaced by "legacy" and "bequest." Researchers tracing the doctrinal ancestry of legacy law, however, will find that American equity courts and early treatise writers (Story, Kent) drew on civilian *legatum* concepts when working out rules for specific versus general legacies, abatement, and ademption — areas where Roman law supplied the conceptual vocabulary that common law lacked.
The maxim quoted in Black's — *Legatum morte testatoris tantum confirmatur, sicut donatio inter vivos traditione sola* (Dyer, 143: "A legacy is confirmed by the death of the testator, in the same manner as a gift from a living person is confirmed by delivery alone") — is useful for understanding the civilian theory of when a testamentary gift becomes effective. It also illustrates that early English common law reporters were citing civilian doctrine directly, making Roman law sources relevant to reading pre-modern English cases.

Historical Dictionary Support
The historical dictionaries are largely consistent. Black's (both editions) and Burrill give the fullest treatment, correctly distinguishing the civil law sense (legacy generally, citing Inst. 2, 20, 1 and Dig. 31, 36) from the English ecclesiastical sense (church legacy or mortuary, citing Cowell). Bouvier and Rapalje & Lawrence give only the English ecclesiastical sense, which understates the term's significance in civilian jurisprudence.
Burrill is the most precise, defining *legatum* as a *donatio testamento relicta* (gift left by will) and attributing to the heir the obligation of performance — a point that tracks the civilian structure accurately and distinguishes *legatum* from *hereditas*.
None of the historical dictionaries survey the Roman law subtypes (*per vindicationem*, *per damnationem*, etc.), meaning researchers who need that level of taxonomy must go directly to the Institutes and Digest, or to civilians such as Gaius, Pothier, or Domat.

Jurisdictional Note
*Legatum* as an operative legal term survives in jurisdictions with civilian inheritance law, including Louisiana, Quebec, and Scottish law, where the vocabulary of legacy retains closer ties to Roman antecedents. In common law jurisdictions, the term is historical and doctrinal only; modern statutes use "legacy," "bequest," or "devise."
