This chapter explains the main features of the registered land system. It aims to understand the need for reform of the land registration system that was introduced in 1925 and describe the main features of the reforms of the Land Registration Act 2002. The chapter describes the transfer of legal title in registered land. It explores how third-party rights are protected on the Register. The chapter also aims to understand the role of third-party rights that override the Register. It discusses the circumstances when the Register can be altered. The registration of a land charge in unregistered land will not trigger registration of title. When unregistered land triggers compulsory registration, the time starts to run in which registration must take place. The transfer of the legal estate in unregistered land takes place on completion of the sale. The law immediately regards the purchaser as the new owner.
