Definition
Forisfactura is a Latin term from medieval and early English law denoting both the act of committing a crime or offense that results in forfeiture and the forfeiture itself. The term carries two interlocking senses:
1. The wrongful act or crime by which a person loses property, rights, or in the most severe cases, life itself. The commission of such an act was understood to work an automatic legal consequence — the forfeiture — as a direct punishment.
2. The forfeiture that results from that act: the loss of goods, lands, or other property to the Crown or to a lord as a consequence of the wrongdoing. In this sense, forisfactura is synonymous with the penalty, not merely the wrong that triggered it.
A related form, forisfactura plena, signified a total forfeiture of all a person's property — the most complete form of the penalty, reserved for the gravest offenses.
Common Confusion
Forisfactura is closely related to, but distinct from, forfeiture in its modern English sense. Modern forfeiture is a procedural and remedial mechanism — civil or criminal — by which the state or a party acquires property connected to wrongdoing. Forisfactura, by contrast, was simultaneously the crime and its consequence: a unified concept in which the offense and the penalty were legally inseparable. Researchers should not read forisfactura as a simple synonym for modern forfeiture without accounting for this historical fusion of act and consequence.
Why It Matters in Research
Forisfactura appears almost exclusively in medieval legal texts, Anglo-Norman records, early English common law treatises, and feudal land records. Researchers encountering the term in primary sources should be alert to several navigational issues.
First, the term shifts in meaning depending on whether it is being used to describe the wrongful act or the resulting penalty. Context is essential — a passage that reads forisfactura as a crime may be using it in the first sense; a passage that speaks of receiving or escheating a forisfactura is using it in the second.
Second, forisfactura plena is a distinct intensified form that appears in records involving attainder, high treason, or feudal forfeiture of an entire fee. When this phrase appears, the researcher is dealing with total dispossession, not a partial penalty.
Third, the term is embedded in feudal tenure doctrine. Forisfactura in manorial and feudal contexts often describes the mechanism by which a tenant's land reverted to the lord upon commission of a felony — a concept later absorbed into the doctrine of escheat and, separately, into the common law rules on attainder and corruption of blood. Researchers working on the history of forfeiture law, attainder, or feudal landholding will find forisfactura a gateway term into those bodies of doctrine.
Fourth, the term does not appear in modern legal usage. Its presence in a source is a reliable indicator of medieval or early modern vintage. If encountered in a 19th-century treatise, it will almost always appear in a historical discussion of feudal law rather than as a live legal concept.
Historical Dictionary Support
Black's Law Dictionary provides the most complete treatment, identifying both the act/crime dimension and the penalty dimension, and separately flagging forisfactura plena as a distinct aggravated form. Black's cites Du Cange and Spelman — the standard glossarists of medieval Latin and Anglo-Norman legal vocabulary — as authorities, which correctly situates the term in the documentary tradition of feudal and ecclesiastical records rather than in common law pleading.
Rapalje & Lawrence treats the term more briefly, rendering it as "forfeit; a crime which works a forfeiture; a fine," which captures the core meaning but loses the plena distinction and the life-or-property severity of the worst-case application. The entry's cross-reference structure also conflates forisfactura with the broader forfeiture category, which may mislead researchers who encounter the term in a feudal rather than purely criminal context.
Neither dictionary adequately explains the feudal-tenure mechanism by which forisfactura operated — namely, that the commission of the disqualifying act was itself the operative legal event, making judicial process in some historical contexts a confirmation rather than a cause of the loss. Researchers relying solely on dictionary definitions should consult the relevant glossary entries in Spelman's Glossarium and Du Cange's Glossarium Mediae et Infimae Latinitatis for the fuller documentary context.
Jurisdictional Note
Forisfactura is specific to English and Anglo-Norman legal history and to jurisdictions whose early law derived from that tradition. It has no independent doctrinal life in American law, though the underlying concepts — particularly total forfeiture of estate upon felony conviction — influenced early American debates over attainder and were addressed in the U.S. Constitution's prohibition on corruption of blood and forfeiture beyond the life of the attainted person.
