n. In law: In the most general sense, the wrongful privation of seizin; ouster.n. In old English law, the violent termination of seizin by the actual ouster of the feudal tenant, and the usurpation of his place and relation. It was a notorious and tortious act on the part of the disseizor, by which he put himself in the place of the disseizee, and, in the character of tenant of the freehold, made his appearance at the lord's court. (Kent.) In more modern use it includes silent entry and usurpation of enjoyment, under pretense of right, with or without title.
