In 1925, England enacted substantial legislation that recast the existing Land Law, and which provided the framework on which modern Land Law was developed for more than seventy-five years. The essential framework remained intact until the enactment of the Land Registration Act 2002, which replaced, and substantially modified, the Land Registration Act 1925. But while the Land Registration Act 2002 is expected to be an important piece of legislation relating to land ownership in England, the 1925 legislation will still provide a good deal of the theoretical underpinning of the subject. This chapter discusses the main strategies of the Land Registration Act 1925, focusing on its effect on unregistered land. It first describes Land Law after 1925 before turning to legal estates, legal interests in land, equitable rights, land charges registration under the Land Charges Act 1925, unregistrable interests, and classification of interests.
