Definition
A Latin term appearing in old English legal texts, functioning in two grammatical modes. First, as a third-person singular verb: "he does," "he acts," or "he makes." Second, as an impersonal construction meaning "it makes" or "it goes to establish" — that is, a given authority, precedent, or argument contributes to proving a point. The term does not name a legal concept but performs a connective or attributive function in legal Latin prose, linking authority to proposition.
It appears most characteristically in two recurring phrases:
(1) Ad idem facit — "it makes to the same thing" or "it goes to establish the same point." Used by Bracton and other early common law writers to signal that a cited passage supports the conclusion already being drawn. Functionally equivalent to "to the same effect" or "see also" in modern legal writing.
(2) Ad hoc facit — "it makes to this" or "it is pertinent to this." A similar connective phrase signaling that a cited authority is relevant to the immediate proposition. Found in Fleta and other early treatises.
The term also appears in the maxim Qui facit per alium, facit per se — "he who acts through another acts through himself" — a foundational principle of agency and vicarious liability that persists in modern law.
Common Language
Modern common usage (Wiktionary): A suburb of Whitworth in Rossendale borough, Lancashire, England.
Historical common usage (Webster's 1913): Not recorded as a common English word.
Editorial note: The common-language and legal uses share no meaningful connection. The place name is a coincidence of spelling. Researchers encountering facit in legal texts should disregard the geographical sense entirely and read the term as Latin legal prose.
Common Confusion
Facit is sometimes loosely grouped with fecit ("he made it") or facere (the infinitive, "to do/make") in discussions of Latin legal vocabulary. These are grammatically related but contextually distinct. Fecit is past tense and appears in different legal contexts — most notably in property and deed language asserting what a grantor or party did. Facit, present tense, appears in argumentative and expository legal writing as a signal of logical or evidentiary support. The distinction matters when reading original Latin pleadings or treatises where tense carries procedural weight.
Why It Matters in Research
Facit is not a term of art naming a doctrine or right. It is a word of legal Latin syntax, and researchers are most likely to encounter it while reading Bracton, Fleta, Britton, or Year Book material in the original or in early translation. Its function is navigational within those texts: it tells the reader that what follows supports what came before.
The primary research trap is treating facit phrases as citations to discrete holdings rather than as connective tissue in a discursive argument. Bracton in particular uses ad idem facit to stitch together Roman law parallels and native common law practice, and the referenced passage may not stand as independent authority — it is being recruited into a larger argument.
For researchers using Law Mind's corpus of early common law materials, facit serves as a low-level indexing signal: its presence indicates a passage where Bracton or Fleta is drawing cross-support from another part of the treatise or from a Roman source. Tracking these internal cross-references can reveal how the author constructed doctrine, but the cross-referenced passages should be verified independently before being cited as authority.
The phrase Qui facit per alium, facit per se is the significant exception: this is a durable legal maxim with ongoing common law vitality, particularly in agency, tort, and employment law. Researchers who encounter facit in this phrase are dealing with substantive doctrine, not connective syntax.
Historical Dictionary Support
Burrill's Law Dictionary provides the most direct coverage available, correctly identifying facit as a term of old English law derived from facere and distinguishing its two principal grammatical meanings — "he does or acts" and "it makes or contributes to establish." Burrill flags the Bracton usage (fol. 27b, 29) and the Fleta usage (lib. 1, c. 38, § 15; lib. 3, c. 10, § 3), which are the primary source locations for the term in practice.
Historical legal dictionaries generally treat facit briefly, as Burrill does, because it is a particle of argument rather than a defined concept. No historical dictionary offers a substantive doctrinal entry for the term itself. What the historical sources correctly convey is the term's function as a signaling device in Bracton-era legal writing. What they do not supply — and what researchers should seek elsewhere — is a fuller account of how Bracton's use of Roman sources through phrases like ad idem facit shaped the early development of English common law doctrine.
