Under the feudal system in England, a feoffee (/fɛˈf, fˈf/) is a trustee who holds a fief (or "fee"), that is to say an estate in land, for the use of a beneficial owner. The term is more fully stated as a feoffee to uses of the beneficial owner. The use of such trustees developed towards the end of the era of feudalism in the Middle Ages and declined with the formal ending of that social and economic system in 1660. Indeed the development of feoffees to uses may have hastened the end of the feudal system, since their operation circumvented vital feudal fiscal mechanisms.
