Disseisin Law and Legal Definition
Disseisin is the act of wrongfully or unlawfully depriving someone of the freehold possession of property. The term disseisin is derived from French word ‘dessaisine.’ It is the unlawful privation of seisin or estate. Disseisin may be effected either in corporeal inheritances such as house or a land, or incorporeal hereditaments. It may be by abatement, intrusion, discontinuance, or deforcement. Disseisin of incorporeal cannot be an actual dispossession, since it is neither capable of actual bodily possession nor dispossession.
Disseisor is one who puts another out of the possession of his lands wrongfully.
