These rules amend the Land Charges Rules 1974 (S.I. 1974/1286) (the principal rules), which make detailed provision for the keeping of the registers relating to unregistered land in England and Wales, and the procedures and forms for registration and searches in the Land Charges Department. The registers are those required by the Land Charges Act 1972 (c. 61) to be kept by the registrar of HM Land Registry.
