English land law is the law of real property in England and Wales. Because of its heavy historical and social significance, land is a major part of the wider English property law. Ownership of land has its roots in the feudal system established by William the Conqueror after 1066, and with a gradually diminishing aristocratic presence, now sees a large number of owners playing in an active market for real estate. The modern law's sources derive from the old courts of common law and equity which includes legislation such as the Law of Property Act 1925, the Settled Land Act 1925, the Land Charges Act 1972, the Trusts of Land and Appointment of Trustees Act 1996 and the Land Registration Act 2002, and the European Convention on Human Rights. At its core, English land law involves the acquisition, content and priority of rights and obligations among people with interests in land. Having a property right in land, as opposed to a contractual or some other personal right, matters because it creates privileges over other people's claims, particularly if the land is sold on, the possessor goes insolvent, or when claiming various remedies, like specific performance, in court.
