English land law is the law of real property in England and Wales. Because of its heavy historical and social significance, land is usually seen as the most important part of English property law. Ownership of land has its roots in the feudal system established by William the Conqueror after 1066, but is now mostly registered and sold on the real estate market. The modern law's sources derive from the old courts of common law and equity, and 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. 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 priority 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.
Land is usually acquired, first, by a contract of sale, and to complete a purchase, the buyer must register their interest with His Majesty's Land Registry. Similar systems run in Scotland and Northern Ireland. Around 15 per cent of land in England and Wales remains unregistered, so property disputes are still determined by principles developed by the courts. Human rights, like the right to a family life and home under ECHR article 8 and the right to peaceful enjoyment of possessions, under article 1 of the First Protocol, apply for everyone. Second, people may acquire rights in land by contributing to a home's purchase price, or to family life, if the courts can find evidence of a common intention that rights should be created. The law acknowledges a "resulting" or "constructive trust" over the property. These interests, and leases under 7 years length, do not need to be registered to be effective. Third, people can acquire land through proprietary estoppel. If someone is given an assurance that they will receive property, and they rely on this to their detriment, a court may acknowledge it. Fourth, adverse possession allows people who possess land, without formal objection by the owner, although this is now difficult to achieve in respect of a registered title.
