Fee simple
Common law

However, the Crown can grant ownership in an abstract entity – called an estate in land – which is what is owned rather than the land it represents. The fee simple estate is also called "estate in fee simple" or "fee-simple title", or sometimes simply "freehold" in England and Wales. From the start of the Norman period, when feudalism was introduced to England, the tenant or "holder" of a fief could not alienate (sell) it from the possession of his overlord. However, a tenant could separate a parcel of the land and grant it as a subordinate fief to his own sub-tenant, a process known as sub-enfeoffing or " subinfeudation ". The 1290 Statute of Quia Emptores abolished subinfeudation and instead allowed the sale of fee simple estates.
