Definition
An archaic Scots law verb meaning to forfeit. Foirfault denotes the act of losing property, rights, or privileges as a legal penalty — typically through attainder, conviction, or breach of feudal obligation. The term is the Scottish equivalent of the English "forfeit" and appears in early Scottish legal proceedings and statutes in contexts where property or title escheated to the Crown or a superior lord as a consequence of crime or civil default.
Common Confusion
Foirfault is occasionally encountered alongside the related noun foirfaulture (the act or condition of forfeiture) and should not be conflated with the English legal term FORFEITURE, which, while functionally identical in meaning, carries a distinct doctrinal and procedural lineage through English common law. A researcher finding foirfault in a Scottish source should resist mapping English forfeiture doctrine onto it without first confirming the applicable Scots law framework in force at the time.
Why It Matters in Research
This term appears almost exclusively in pre-union Scots law materials. Researchers are most likely to encounter it when working with Scottish state trial records, particularly the Howell's State Trials compilation (cited in all three source dictionaries as 1 How. State Tr. 927), and in early Scottish parliamentary or feudal records. Several navigational notes apply:
First, foirfault is a verb form. Scottish legal instruments of the period often use it as a term of operative effect — "he shall foirfault his lands" — rather than as a descriptive noun. Researchers reading primary documents should recognize the word as effecting forfeiture rather than merely describing it.
Second, the term belongs to a pre-codification Scots law environment. After the Acts of Union (1707), Scots law underwent significant integration and modernization, and archaic terms like foirfault were replaced by modern equivalents in legal drafting. Finding this term is therefore a reliable signal that the document dates from or concerns legal proceedings from the pre-union period, or that the source itself (such as Howell's) is reporting on older proceedings.
Third, Law Mind corpus researchers working on forfeiture topics across jurisdictions should be careful not to treat Scottish and English authorities as interchangeable. The substantive law of foirfaulture in Scotland — including the grounds, procedures, and consequences — developed with reference to Scots feudal law and Roman law influences, not exclusively from English common law.
Fourth, because the word's phonetic similarity to its English cognate "forfault" (itself an archaic English variant) may cause the term to surface in full-text searches designed to retrieve English materials, researchers should verify the jurisdiction of any document in which the term appears before drawing doctrinal conclusions.
Historical Dictionary Support
All three source dictionaries — Black's (1st ed.), Black's (2nd ed.), and Burrill's — are in complete agreement: foirfault means, in old Scots law, to forfeit. All three cite the same source, 1 How. State Tr. 927 (Howell's State Trials, Volume 1), indicating the historical dictionaries drew from a common root and that the evidentiary basis for the entry is narrow but consistent.
What the historical dictionaries do not provide is any doctrinal elaboration: there is no discussion of the legal contexts in which foirfaulture operated, no reference to the feudal or criminal law mechanisms that triggered it, and no treatment of the noun form. The entries function purely as translation glosses for a reader who has encountered the term in a primary source. This is appropriate given the term's status as a functional equivalent of an English concept, but it leaves the researcher without guidance on the substantive Scots law underlying the word's use. Burrill adds the Scottish jurisdiction marker "Sc." explicitly; the Black's editions accomplish the same by the phrase "old Scotch law."
Jurisdictional Note
Foirfault is exclusively a term of Scots law and has no recognized usage in English, Irish, or colonial American legal materials. Researchers working in any jurisdiction other than Scotland, or in Scottish law post-1707, are unlikely to encounter the term in operative legal documents.
