A benefice or living is a reward received in exchange for services rendered and as a retainer for future services. The Roman Empire used the Latin term beneficium as a benefit to an individual from the Empire for services rendered. Its use was adopted by the Western Church in the Carolingian Era as a benefit bestowed by the crown or church officials. A benefice specifically from a church is called a precaria, such as a stipend, and one from a monarch or nobleman is usually called a fief. A benefice is distinct from an allod, in that an allod is property owned outright, not bestowed by a higher authority.

A fief was a central element in medieval contracts based on feudal law. It consisted of a form of property holding or other rights granted by an overlord to a vassal, who held it in fealty or "in fee" in return for a form of feudal allegiance, services or payments. The fees were often lands, land revenue or revenue-producing real property like a watermill, held in feudal land tenure: these are typically known as fiefs or fiefdoms. However, not only land but anything of value could be held in fee, including governmental office, rights of exploitation such as hunting, fishing or felling trees, monopolies in trade, money rents and tax farms. There never existed a standard feudal system, nor did there exist only one type of fief. Over the ages, depending on the region, there was a broad variety of customs using the same basic legal principles in many variations.
