DISSEISIARE

Definition

To disseise. A Latin verbal form drawn from medieval common law pleading and land law, meaning the act of wrongfully dispossessing a person of their freehold estate — that is, forcibly or unlawfully putting out one who is lawfully seised of land. The term appears principally in Magna Carta (c. 27) and in the Latin pleading records of English courts. It is the verbal root from which the noun DISSEISIN derives. DISSEISIN (the closely related substantive term) means the wrongful dispossession of a freeholder from their seisin — their actual, lawful possession of a freehold estate in land. It is classified in the old common law as a species of ouster, one of the major categories of real injury to possession of land. The disseisor steps into the place of the rightful possessor, holding the land adversely and without right.

Common Confusion

DISSEISIARE and DISSEISIN are root and noun of the same concept and are often encountered together in historical sources, but researchers should not conflate them with simple trespass or with the modern concept of adverse possession. Disseisin is not mere trespass — it involves an actual assumption of the freehold by the wrongdoer, displacing the rightful possessor's seisin entirely. Nor is it identical to adverse possession, which is a modern doctrine through which title may eventually be acquired; disseisin describes the wrongful act of dispossession itself, without implying any ultimate legal right in the disseisor.

Core Elements

Disseisin at common law required: 1. An actual seising party — the plaintiff must have been seised of the freehold at the time of dispossession. 2. Wrongful dispossession — the ouster must have been without right or lawful authority. 3. Assumption of the freehold by the disseisor — not merely interference with use or enjoyment, but an actual taking of the freehold possession itself. 4. A freehold estate — disseisin applied to freehold tenures; dispossession of a leaseholder raised different actions and did not technically constitute disseisin.

Why It Matters in Research

DISSEISIARE appears almost exclusively in Latin legal records, Magna Carta scholarship, and early common law pleading materials. Researchers working in these areas should be aware of several navigational points. First, the term surfaces in Chapter 29 (sometimes cited as Chapter 27 in earlier numbering systems) of Magna Carta, where the Crown pledged not to disseise any free man of his freehold without lawful judgment — one of the foundational constitutional guarantees of the charter. Any research into the constitutional history of due process or property rights will encounter this term at the root of the argument. Second, disseisiare and its noun form disseisin are organizing concepts for the old real actions — particularly the assize of novel disseisin, which was one of Henry II's great procedural reforms providing a swift remedy for recent dispossession. Without understanding disseisin, the mechanics of the real actions become opaque. Third, when reading Coke, Blackstone, Littleton, or the Year Books, the distinction between seisin, disseisin, and possession carries enormous doctrinal weight. Modern property law has collapsed many of these distinctions, and researchers importing modern assumptions into historical sources will misread them. The concept of seisin is not the same as modern legal title or even modern possession. Fourth, the corpus of Latin legal records using disseisiare and its variants (disseisire, dissaisire, dissasina) is not uniform in spelling. Researchers in manuscript sources or plea rolls should expect wide orthographic variation.

Historical Dictionary Support

Burrill's Law Dictionary defines disseisiare as simply "to disseise," anchored by the citation to Magna Carta, c. 27, and develops the substantive concept fully under DISSEISIN. Burrill draws on Coke upon Littleton (277a), Blackstone's Commentaries (3 Bl. Com. 169), Stephen's Commentaries (3 Steph. Com. 483), and Littleton's Tenures (sect. 279) — the canonical authorities on real property and seisin in English common law. This citation cluster signals that by the nineteenth century, disseisin was understood as a settled, mature concept whose primary importance was historical and doctrinal rather than actively litigated. Burrill's characterization — "a wrongful putting out of him that is actually seised of the freehold" and "a species of injury by ouster or dispossession" — reflects standard common law doctrine faithfully. What Burrill does not address is the constitutional dimension of the term as it appears in Magna Carta, which became the more significant thread in later legal history. Researchers looking to Burrill for the constitutional importance of disseisiare in the development of due process will need to supplement with Magna Carta scholarship directly.

Jurisdictional Note

Disseisin as a formal cause of action is obsolete in modern American and English law, displaced by simplified real property actions and the recording system. However, the concept survives in American constitutional scholarship as part of the interpretive history of due process clauses, and some jurisdictions' adverse possession statutes retain language traceable to the disseisin framework.
