In English common law, fee tail or entail is a form of trust, established by deed or settlement, that restricts the sale or inheritance of an estate in real property and prevents that property from being sold, devised by will, or otherwise alienated by the tenant-in-possession, and instead causes it to pass automatically, by operation of law, to an heir determined by the settlement deed. The term fee tail is from Medieval Latin feodum talliatum, which means "cut(-short) fee". Fee tail deeds are in contrast to "fee simple" deeds, possessors of which have an unrestricted title to the property, and are empowered to bequeath or dispose of it as they wish (although it may be subject to the allodial title of a monarch or of a governing body with the power of eminent domain). Equivalent legal concepts exist or formerly existed in many other European countries and elsewhere. Most common law jurisdictions have abolished fee tails or greatly restricted their use. They survive in limited form in England and Wales, but have been abolished in Scotland, Ireland, and all but four states of the United States. The fee tail allowed a patriarch to perpetuate his blood-line, family-name, honour and armorials in the persons of a series of powerful and wealthy male descendants. By keeping his estate intact in the hands of one heir alone, in an ideally indefinite and pre-ordained chain of succession, his own wealth, power and family honour would not be dissipated amongst several male lines, as became the case for example in Napoleonic France by operation of the Napoleonic Code which gave each child the legal right to inherit an equal share of the patrimony, where a formerly great landowning family could be reduced in a few generations to a series of small-holders or peasant farmers. It therefore approaches the true corporation which is a legal body or person which does not die and continues in existence and can hold wealth indefinitely. Indeed, as a form of trust, whilst the individual trustees may die, replacements are appointed and the trust itself continues, ideally indefinitely.
