Definition
Belonging to; appurtenant to. A participial form of the verb "appertain," used in conveyancing and property instruments to describe a relationship of connection, use, or occupancy between one thing and another — most commonly between land or a right and a primary property holding. When land, an easement, or other interest is described as "appertaining" to a messuage or estate, it signals that the subordinate thing goes with the principal holding as a matter of legal attachment, not merely physical proximity.
The term appears most frequently in the formulaic language of deeds — phrases such as "together with all rights and privileges appertaining thereto" — where it signals that ancillary rights, easements, or parcels pass with the main conveyance.
Common Language
Modern common usage (Wiktionary): Present participle and gerund of "appertain" — a formal or literary word meaning to belong or relate to something.
Historical common usage (Webster's 1913): To belong or pertain; to relate; to be the property, right, or duty of.
The common meaning is close to the legal meaning in feel, but imprecise in application. In ordinary use, "appertaining" can describe any loose relationship of relevance. In property law, it carries a specific legal consequence: what appertains to an estate travels with it on conveyance. The difference between a casual connection and a legally attached interest is exactly what courts have been asked to resolve.
Common Confusion
"Appertaining" and "adjoining" are not synonymous, though the two words appear together in deed language and are sometimes treated as interchangeable. "Adjoining" ordinarily imports physical contiguity — the land touches. "Appertaining" imports use, occupancy, or legal connection — the interest belongs. One parcel or right may appertain to another without being contiguous to it; conversely, two parcels may be physically adjoining without either appertaining to the other in the legal sense. This distinction has been litigated in deed construction cases, and researchers consulting older instruments should not assume the words were used with technical precision.
Why It Matters in Research
"Appertaining" is a term of conveyancing art, and its significance in any document lies in context. In modern instruments, it often appears in boilerplate and is treated as surplusage. In historical deeds, it may be the operative word determining which rights pass with a grant and which do not.
Several research traps exist. First, the term is frequently paired with "appurtenant" and "appertaining thereto" as near-synonyms in the same instrument; researchers should not assume the drafter intended a distinction. Second, older cases applying this word often involve construction of specific deed language in a particular jurisdiction, and the outcome turns heavily on surrounding text — general rules extracted from those cases travel poorly. Third, the gap between "appertaining" (legal connection) and "adjoining" (physical contact) is a live issue in title disputes and easement cases; searching for one without the other in historical court records may miss relevant authority.
For corpus researchers, this term is most useful as a navigational marker: when it appears in a deed or grant, look for accompanying language defining what is being treated as appurtenant and trace whether any separate instrument created that attachment.
Historical Dictionary Support
The historical dictionaries converge on a core definition — belonging to; appurtenant — and uniformly treat "appertaining" as a cross-reference to the fuller entry at "Appurtenant." Burrill and Black both cite this redirect explicitly. Rapalje & Lawrence adds the functional Latin derivation (ad + pertinere, to reach to) without further elaboration.
Bouvier's is the most substantive, and stands apart from the others on one practical point: it preserves the distinction between "appertaining" and "adjoining" as a matter of deed construction, citing authority for the proposition that use and occupancy, not physical contact, is the operative test. Bouvier also notes that "appertaining" typically describes land lying with or usually occupied with a messuage — a usage that situates the term firmly in the older English property vocabulary of principal tenement and associated holdings.
None of the historical dictionaries address the risk of treating "appertaining" as mere boilerplate, which is the more common research problem in modern document review.
