Definition
Habitation carries two distinct legal meanings depending on context.
1. Civil law right of habitation. A personal servitude entitling its holder to dwell in another person's house, or a portion of it, together with family and household. The right is strictly personal — it cannot be leased or assigned and does not extend to commercial exploitation of the premises. Unlike usufruct, it is limited to residential use and belongs to the individual recipient rather than to the estate in any transferable sense. Under Justinian's refinements, the right was held to accrue day by day rather than as a single aggregate entitlement, which had the practical consequence that it was not forfeited by non-use. Justinian also permitted it to be let, a point of controversy among earlier jurists.
2. Property law (common law). A dwelling-house; a place of habitual residence or settled abode. In this sense the term functions as a synonym for dwelling and is used in statutes governing burglary, trespass, zoning, landlord-tenant obligations, and constitutional protections for the home.
Common Language
Modern common usage (Wiktionary): The act of inhabiting; a place of abode, settled dwelling, or residence; also, a group or company (as of the Primrose League).
Historical common usage (Webster's 1913): The act of inhabiting; state of inhabiting or dwelling, or of being inhabited; occupancy. A place of abode; settled dwelling; residence; house.
The common meaning and the property-law meaning are nearly identical — both center on a dwelling place. The gap lies in the civil law usage, which treats habitation not as a description of a place but as a named personal right, a servitude with defined legal content distinct from ownership, usufruct, and simple use. A researcher encountering "habitation" in a civil-law or Louisiana source must recognize that the word is doing technical work, not merely describing a house.
Recognized Forms
/SUBTYPES
Right of habitation (droit d'habitation). The formal civil-law servitude described in Definition 1 above. Recognized in jurisdictions with civil law heritage, notably Louisiana, Quebec, and continental European systems. Distinguished from usufruct by its restriction to personal residential use and, historically, by its non-extinguishment through non-use.
Habitation as dwelling. The common law and statutory sense. Appears in burglary definitions (the inhabited structure requirement), landlord-tenant habitability standards, and constitutional home-protection doctrines.
Why It Matters in Research
The term is a quiet jurisdictional trap. In a Louisiana source, a nineteenth-century civil law treatise, or any document drawing on Roman or French law, "habitation" almost certainly refers to the personal servitude — a technical concept with specific rules about creation, duration, transmissibility, and extinction. In a common law source covering property, criminal law, or housing regulation, the same word is simply a synonym for dwelling. Conflating the two readings can produce fundamental misunderstandings about the nature of the right being discussed.
Researchers working in landlord-tenant law should be alert to the modern doctrinal neighbor: the implied warranty of habitability. That warranty is a creature of twentieth-century common law development and uses "habitability" (the adjective form) rather than "habitation," but the conceptual connection is direct — both concern the adequacy of a dwelling for residential use. Historical sources will not use "implied warranty of habitability" as a term of art; the doctrine postdates the classical dictionaries.
In criminal law sources, particularly burglary statutes and their annotations, habitation or "inhabited dwelling" defines the protected class of structure. The scope of that definition — whether a temporarily vacant house qualifies, whether a commercial space used partly for sleeping qualifies — has generated substantial case law that historical dictionaries do not address.
The Rapalje & Lawrence entry introduces a nuance worth noting for civil law research: the day-by-day accrual theory of habitation meant that bequest of the right was treated as a series of separate bequests for each day, not a single transfer. This structural peculiarity affected how courts and jurists reasoned about interruption, non-use, and extinction. It is a detail absent from Black's and Anderson's and will not surface without consulting the more analytically detailed sources.
Historical Dictionary Support
Black's (1st Ed.) gives the clearest structural account: habitation differs from usufruct because the usufructuary may use the premises for any purpose (commercial, productive), while the habitatio holder is confined to residential use for self and family. The authority cited — Browne's Civil Law — grounds the definition in the civil law tradition rather than English practice.
Black's (2nd Ed.) largely repeats this account but adds the Scottish "habit and repute" marriage doctrine as a neighboring entry, a reminder that "habit" and "habitation" share etymological territory without sharing legal content.
Rapalje & Lawrence goes further analytically, drawing on Justinian to distinguish habitation from both the jus utendi (right of use) and the jus fruendi (right of enjoyment). The day-by-day accrual point and the non-extinguishment by non-use are contributions not found in Black's. This makes Rapalje & Lawrence the more useful source for a researcher working in civil law contexts who needs to understand how the servitude actually functioned.
Anderson's Dictionary of Law redirects the reader to "Dwelling" and does not develop the civil law right independently, which limits its utility for this term specifically.
What the historical dictionaries collectively miss: the modern implied warranty of habitability, the constitutional dimensions of home protection under Fourth Amendment doctrine, and the specific statutory definitions of "habitation" embedded in criminal codes. For any research touching those areas, the dictionaries are starting points only.
Jurisdictional Note
Louisiana recognizes the right of habitation as a formal personal servitude under its Civil Code, directly descended from the Roman and French civil law tradition. Common law jurisdictions do not recognize the civil law servitude as such but use habitation as a descriptive term in statutes and case law. The implied warranty of habitability, while doctrinal rather than statutory in origin, is now recognized in most U.S. states, though its scope and remedies vary.
