Socage was one of the feudal duties and hence
land tenure forms in the
feudal system. A farmer, for example, held the land in exchange for a clearly defined, fixed payment to be made at specified intervals to his feudal lord, who in turn had his own feudal obligations, to the farmer and to the Crown. In theory this might involve supplying the lord with produce but most usually it meant a straightforward payment of cash, i.e.,
rent.
