Definition
Possessio bonorum is a Latin term from Roman civil law meaning "possession of goods" or "possession of an estate." It refers to the praetorian institution by which a Roman magistrate (the praetor) granted a claimant possession of a decedent's property — functioning as an equitable alternative or supplement to the strict civil law rules governing succession. The term is the inverted form of the more commonly encountered phrase bonorum possessio, which designates the same institution and is the preferred usage in both historical legal literature and modern scholarship.
Common Confusion
Possessio bonorum and bonorum possessio refer to the same Roman law concept. The word order is simply reversed. Historical dictionaries uniformly flag possessio bonorum as the less standard form and redirect the reader to bonorum possessio. Researchers should not treat these as separate institutions. Confusion also occasionally arises with possessio simpliciter — bare physical possession of a thing — which is a distinct concept without the succession-law context that defines bonorum possessio.
Why It Matters in Research
The primary research value of this entry is navigational: encountering possessio bonorum in a historical source is a signal to redirect research toward bonorum possessio, where the substantive doctrine is treated. Sources from the civil law tradition — Scottish, Louisiana, South African, and mixed-jurisdiction materials in particular — may use either word order without explanation, and a researcher unfamiliar with the inversion may fail to locate the relevant commentary.
Two traps are worth noting. First, possessio bonorum appears in older English legal writing that engaged seriously with Roman law sources, including equity treatises concerned with the praetor's jurisdiction as an analogue to Chancery. A researcher tracing the intellectual history of equitable succession doctrines may encounter the term in this context and need to follow it into the Roman law literature. Second, possessio in Roman law carries a specific technical meaning — a legally cognizable holding protected by interdicts — that differs from mere physical detention. Reading possessio bonorum as simply "having goods" misses this protected-possession dimension entirely.
For Law Mind corpus researchers: entries on bonorum possessio, praetorian law, and Roman succession should be consulted together. The term also connects to corpus materials on the historical development of equity jurisdiction, where the praetor's role in Roman law was frequently cited by English Chancery writers to legitimize equitable intervention.
Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in complete agreement: both define possessio bonorum as the possession of goods under civil law and both redirect the reader to bonorum possessio as the more common and authoritative form. Neither entry develops the substantive doctrine here — that work is reserved for the bonorum possessio entry.
What both historical dictionaries omit, and what a researcher should supply from civilian sources, is the institutional texture: bonorum possessio was not mere factual possession but a praetorian grant, temporary in character and subject to confirmation or displacement, which allowed the praetor to correct outcomes under the strict civil law of succession that he found inequitable. The term thus sits at the intersection of Roman property law and Roman family and succession law.
Jurisdictional Note
Possessio bonorum as a live legal term is confined to jurisdictions with a civilian heritage. It appears in historical Scottish and South African legal writing and in Louisiana succession law scholarship. Common law jurisdictions encounter it, if at all, only in academic or comparative contexts.
