England and Wales: the core application
HM Land Registry asks for AP1 and original or certified linking evidence, such as a marriage certificate, deed poll, statement of truth or statutory declaration. For an unrepresented application it also asks for identity confirmation in the new name, using ID1 or the appropriate remote ID3 route, plus an official document in the former name. Follow the live requirements and verifier eligibility. HM Land Registry: update or correct the register
