What does disseise mean?
Disseise is a legal verb meaning to wrongfully deprive someone of the possession of land, particularly freehold property. It belongs to the vocabulary of English property law and is closely tied to the medieval concept of seisin — the formal legal possession of an estate. A person so deprived was said to be 'disseised of' their land, and the wrongful act itself was called a disseisin. The word gained prominence through remedies such as the Assize of Novel Disseisin, established under Henry II in the twelfth century, which allowed a dispossessed tenant to sue swiftly for recovery of land in the royal courts. Today disseise appears almost entirely in historical, academic, and specialist legal contexts rather than everyday speech. Its enduring value lies in its precision: where 'dispossess' can apply to any kind of eviction or loss of belongings, disseise denotes specifically the unlawful ouster from real property, making it indispensable in discussions of feudal tenure and the origins of the common law.
verbTo wrongfully deprive a person of the legal possession of land or property, especially of freehold estate; to dispossess.
- (Law, transitive) To wrongfully deprive (a person) of the seisin — the legal possession — of freehold land or other real property; to dispossess by unlawful ouster.
"The baron disseised his widow of the estate within weeks of the funeral."
"Under the Assize of Novel Disseisin, a tenant who had been disseised could recover his land swiftly by royal writ."
"The heir claimed he had been disseised of his inheritance by a forged deed executed during his minority."
This medieval land-law verb survives today almost solely inside the phrase 'disseised of his freehold' — a fossil from an age when losing your land meant losing your standing at court.

Etymology of disseise
Disseise derives from Anglo-Norman and Old French 'desseis-', the stem of 'desseisir', formed from the prefix des- (expressing reversal) plus 'seisir', meaning to put in possession of. The French verb traces back through Vulgar Latin *sedacium to Latin sedere, meaning to sit, reflecting the ancient idea that lawful possession was symbolized by sitting upon or occupying land. The same root gave English related words including seize, assize, and siege. The term entered Middle English in the context of Norman land law and has remained fixed in legal usage ever since.
