Socage (/ˈsɒkɪdʒ/) was one of the feudal duties and land tenure forms in the English feudal system. It eventually evolved into the freehold tenure called "free and common socage", which did not involve feudal duties. Farmers held land in exchange for clearly defined, fixed payments made at specified intervals to feudal lords. In turn, the lord was obligated to provide certain services, such as protection, to the farmer and other duties to the Crown. Payments usually took the form of cash, but occasionally could be made with goods.
Socage contrasted with other forms of tenure, including serjeanty, frankalmoin and knight-service.
