Definition
In law, FOOT carries two distinct meanings:
1. A unit of linear measurement equal to twelve inches, or one-third of a yard. Used in property descriptions, surveys, easements, building codes, and any legal instrument requiring precise measurement of distance or length.
2. Figuratively, the base, bottom, end, or conclusion of a legal instrument or proceeding. Most commonly encountered in the phrases "foot of the fine" and "foot of the account," where it denotes the terminal or concluding portion of a document or reckoning.
Common Language
Modern common usage (Wiktionary): The biological structure at the terminal end of the leg used for standing and walking; also, the base or bottom of anything; a unit of length equal to twelve inches.
Historical common usage (Webster's 1913): The terminal part of the leg below the ankle; that part of an animal upon which it rests when standing or moves; also the base or bottom of a thing.
The common meaning and the legal meaning largely overlap for both senses — the measurement sense is identical, and the figurative "base or bottom" sense tracks ordinary usage. The one gap worth noting is the technical legal application to instruments of record: phrases like "foot of the fine" are terms of art in conveyancing and have no equivalent in everyday speech, though they derive naturally from the ordinary "bottom of the page" sense.
Recognized Forms
/SUBTYPES
Foot of the fine: The concluding clause of a fine — a now-obsolete form of conveyance — which contained the names of the parties, the property description, and the consideration. The "foot" was the third and lowest part of the indenture, the portion retained by the court of record.
Foot of the account: The final balance or sum at the end of an accounting, as distinguished from individual line items. References in equity proceedings and estate accountings.
Foot-way: A right of way restricted to passage on foot. Distinguished from a cartway or road. See related entries for EASEMENT and BRIDGE.
Why It Matters in Research
Researchers encounter FOOT most often in two contexts that require different handling.
In property and survey documents, foot as a unit of measurement is stable and unambiguous. The main research trap is period-specific variation in what counts as a "foot" — historical surveys, particularly colonial-era American and English land records, sometimes used local or customary measures that did not correspond exactly to the modern standard foot. A "foot" in an eighteenth-century deed may warrant verification against contemporary surveying practice for that jurisdiction.
The figurative legal use — foot of the fine, foot of the account — is historically significant and nearly obsolete in modern practice. Fines as a mode of conveyance were abolished in England in the early nineteenth century and were never widely used in the same form in American jurisdictions. Researchers working in pre-nineteenth-century English or colonial American property records will encounter this usage; those working in modern materials almost certainly will not. The phrase "foot of the fine" appears in older treatises and digests as a technical term of conveyancing art. Misreading it as a reference to measurement rather than document structure would be a serious interpretive error.
Anderson's Dictionary of Law redirects to POSSESSIO PEDIS (possession by the foot, i.e., actual physical possession of land), a conceptually adjacent but distinct term. Researchers who encounter "pedis" in Latin legal texts should not conflate it with the measurement or document-structure senses of FOOT.
Historical Dictionary Support
The historical dictionaries are in close agreement. Black's (both editions) and Bouvier's each recognize the same two meanings — the linear measure and the figurative "base or end" sense — with nearly identical language. Bouvier adds a useful clarification that the figurative sense specifically covers the "conclusion" and "end" of an instrument, and cites cases in point. Anderson's is notably brief, cross-referencing rather than defining, which reflects the term's status as a functional word with specialized applications rather than an independent term of art.
What the historical dictionaries do not address: the possibility of variation in the customary foot across time and jurisdiction, the foot-way as a species of easement (Anderson gestures at this but does not develop it), and any metric conversion context — unsurprisingly, given their dates of publication.
Jurisdictional Note
As a unit of measurement, the foot is uniform across U.S. jurisdictions and codified in federal and state weights-and-measures statutes. In property survey contexts, the U.S. survey foot and the international foot differ by a small but legally significant margin in high-precision work; this distinction matters in boundary litigation involving modern survey instruments.
