Definition
In Roman and civil law, adire means to go to, approach, or apply to — and more specifically, to enter upon or accept an inheritance. The term describes the act by which an heir formally accepts a succession, thereby becoming liable for the estate's obligations and entitled to its assets. The phrase adire hereditatem (to enter upon the inheritance) was the standard formulation in classical Roman law for this acceptance.
The concept is functionally equivalent to what common law systems would call acceptance of an inheritance or assent by an executor, though the civil law framework attached distinct procedural and legal consequences to the moment of adition.
Common Language
Modern common usage (Wiktionary): A type of traditional Yoruba tie-dyed cloth from West Africa.
Historical common usage (Webster's 1913): Not listed — the term had no English common meaning in the nineteenth century.
Editorial note: The English word "adire" in modern usage refers exclusively to a West African textile tradition and has no connection whatsoever to the Latin legal term. A researcher encountering "adire" in an English-language context must determine immediately whether the source is a civil law text (where the Latin legal meaning applies) or a contemporary reference (where the cloth meaning is almost certainly intended). The two meanings share nothing beyond spelling.
Common Confusion
Adire is sometimes loosely conflated with aditio hereditatis, which is the formal noun form denoting the act or institution of entering upon an inheritance, as distinct from adire as a verb describing the action itself. In Burrill and similar digests, the two appear in close proximity, and researchers may treat them as interchangeable. They are not: adire describes the act of going to or approaching; aditio is the legal institution — the formal acceptance event — that the act constitutes. The distinction matters when tracing doctrinal development in civil law succession theory.
Why It Matters in Research
Researchers working in civil law succession, Roman law sources, or comparative inheritance law will encounter adire primarily in Latin quotations embedded in English-language digests and commentaries. Burrill's entry illustrates the pattern: the definition is brief, the supporting citations are to the Digest (Dig. 29.2), the Institutes (Inst. 2.19.4), and Bracton (fol. 227a), and the operative concept — the moment of hereditary acceptance — is left to the reader to develop from context.
The phrase hæreditas dum jacet non adita (an inheritance lying not yet entered upon) is the key correlate concept. "Hereditas jacens" — the estate in suspense before acceptance — was a significant Roman law doctrine, and adire is the act that terminates that suspended state. Researchers tracing the development of estate liability, creditor rights against a succession, or the timing of title transfer in civil law systems need to track this moment carefully. Sources that predate formal acceptance doctrine may treat title as passing automatically; later civil law refinements made adition the operative trigger.
In common law research, adire rarely appears except in scholarly treatments of Roman law influence or in comparative law materials. Do not expect to find it in English case law or statutes. If it appears in a common law source, it is almost certainly a Latin quotation from a civil law authority being cited for doctrinal support, not a term of art with independent common law force.
Bracton's use of the term (fol. 227a) is notable because it places adire in a medieval English treatise that drew heavily on Roman and canon law. Researchers using Bracton as a source should understand that his adire references reflect Roman inheritance doctrine being imported into a common law discussion, not native English succession vocabulary.
Historical Dictionary Support
Burrill's Law Dictionary provides a compact but well-sourced entry. He defines adire through three distinct senses — to go to, to approach or apply to, and to enter upon or accept — and grounds the succession meaning in the Digest and Institutes directly. His citation to Bracton connects the Roman term to its English-language reception. The entry is representative of mid-nineteenth-century legal dictionary practice: Latin terms are defined functionally, citations are to primary civil law sources, and no attempt is made to map the term onto common law equivalents.
What Burrill does not provide is any discussion of the procedural mechanics of adition — whether it required formal declaration, whether it could be tacit, or how civil law systems distinguished voluntary from necessary heirs. Researchers needing that doctrinal depth must move from Burrill to the primary sources he cites.
Jurisdictional Note
Adire is a term of Roman and civil law with no operative role in common law jurisdictions. It remains relevant in civilian systems (Louisiana, Quebec, Scotland, and civil law countries generally) where succession law retains formal acceptance doctrine. Common law researchers encounter it only in historical and comparative contexts.
