In common law jurisdictions (e.g. England and Wales, United States, Australia,Canada and Ireland), a freehold is the common ownership of real property, or land, and all immovable structures attached to such land, as opposed to a leasehold, in which the property reverts to the owner of the land after the lease period has expired.
For an estate to be a freehold, it must possess two qualities: immobility (property must be land or some interest issuing out of or annexed to land) and ownership of it must be of an indeterminate duration. If the time of ownership can be fixed and determined, it cannot be a freehold.
In England and Wales, before the Law of Property Act 1925, a freehold estate transferable to the owner's "heirs and assigns" (that is, successors by inheritance, or purchase [including gift], respectively) was a fee simple estate. When transfer, by inheritance or otherwise, was limited to lineal descendants ("heirs of the body" or "heirs of the blood") of the first person to whom the estate was given, it was a fee tail estate. There were also freehold estates not of inheritance, such as an estate for life.
