Definition
Forisfactura (also spelled forisfaoctura in some manuscript traditions) is a Latin term from medieval law denoting: (1) a crime or offense by which a person's property is forfeited to the crown or lord; (2) the forfeiture itself — the loss of property, and in some contexts life, as a consequence of that crime; (3) a monetary fine or pecuniary punishment imposed as a legal penalty. The term thus operates simultaneously as a description of the wrongful act, the legal consequence flowing from it, and the thing forfeited.
Sub-definition — Forisfactura plena: The complete or full forfeiture of all a person's property, as distinguished from partial forfeitures attached to lesser offenses.

Common Confusion
Forisfactura is easily conflated with the related terms forfeiture and attainder, but each has a distinct scope. Forfeiture (modern usage) is the general loss of property as a legal penalty and survives robustly in contemporary law. Attainder specifically concerned the civil and legal death of a person convicted of treason or felony, with corruption of blood as a consequence — a concept abolished in English and American law. Forisfactura, by contrast, was the medieval Latin vehicle for the entire spectrum of property loss tied to criminal offense, encompassing what modern law would separate into criminal forfeiture, civil forfeiture, and fine. Researchers encountering forisfactura in historical sources should resist mapping it directly onto any single modern concept.

Why It Matters in Research
Forisfaoctura is a term encountered almost exclusively in medieval Latin legal records, Anglo-Norman charters, Domesday-era texts, and early common law treatises. Researchers working in the Law Mind corpus should be alert to several navigational issues:
Spelling instability. The variant forisfaoctura appearing in some manuscript traditions (and reflected in this entry's headword) is a scribal or typographical corruption of the classical form forisfactura. Both spellings will appear in historical sources; search queries in digitized records should account for both, as well as the abbreviated forms forf. and forisfact.
Dual register of the term. In medieval usage, forisfactura could refer to the act (the offense giving rise to forfeiture) or the consequence (the forfeited property itself). A document recording that a lord received a man's forisfactura might be recording either the jurisdictional right to punish or the actual goods received. Context — and the accompanying Latin case endings — governs which meaning applies.
Connection to feudal and criminal law overlap. The term bridges what modern law treats as separate domains. In the feudal context, forisfactura could arise from breach of fealty or other tenurial obligations, not only from what we would now call criminal acts. Researchers tracing the history of criminal forfeiture back through English law will find forisfactura doing work that modern doctrine distributes across several distinct legal categories.
Forisfactura plena as an extreme sanction. The sub-form forisfactura plena signals total dispossession and appears in texts discussing the gravest offenses. It is an antecedent concept to the later doctrines of attainder and corruption of blood and connects historically to debates about whether and how the state may strip a person of all legal and property rights. Researchers tracing constitutional limits on forfeiture in American law may find it useful to trace this lineage, even though forisfactura itself has no direct doctrinal force in modern courts.
Corpus connections. This term is most productively read alongside Law Mind materials on forfeiture, attainder, escheat, and feudal tenure. It will appear in the background of entries on those subjects and in primary source supplements to historical common law texts.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) is the primary shelf source covering this term, and its treatment is admirably compact: it defines forisfactura as a crime or offense through which property is forfeited, a fine or monetary punishment, forfeiture, and the loss of property or life in consequence of crime, before separately defining forisfactura plena as total forfeiture of all property. Black's correctly cites Du Cange (the standard medieval Latin lexicon, Glossarium Mediae et Infimae Latinitatis) and Spelman (Sir Henry Spelman's Glossarium Archaiologicum) as underlying authorities — the two indispensable reference works for terms of this kind.
What Black's does not do is distinguish between the use of forisfactura as an offense-description versus a consequence-description, a distinction that matters considerably when reading primary sources. It also does not address the feudal dimension — the use of the term in tenurial rather than criminal contexts. Researchers relying solely on Black's will have a serviceable starting definition but should consult Du Cange directly for the full range of medieval usage, which is considerably richer and more varied than any common law dictionary entry can capture.
No other Law Mind shelf dictionaries include this term, which reflects its status as a historical Latin term without surviving doctrinal life in modern Anglo-American law.

Jurisdictional Note
Forisfactura has no operative legal force in any modern jurisdiction. Its relevance is purely historical, arising in the context of English medieval law and the feudal systems it regulated. Researchers working with Scottish historical records should note that Scots law preserved distinct Latin terminology drawn from the same roots, and variant forms may appear in Scottish legal manuscripts with meanings that diverge from English usage.
