Feudal Tenure Law and Legal Definition

Feudal tenure is a real property ownership system in which ownership rests with a sovereign who may grant lesser interests in return for service or loyalty. Every estate held by feudal tenure was subject to forfeiture for breach of the conditions on which it was granted. [United States v. Castillero, 67 U.S. 17, 228 (U.S. 1863)].

Feudal tenure had as its foundation, the principle or fiction that, the king is the universal lord and original proprietor of all the lands in his kingdom and that no man possesses or can possess any part of such lands which has not been derived as a gift from the king, to be held upon feudal services.
