Statutory declaration, statement of truth or affidavit, which do I need?
All three are formal statements of fact, and the wrong one is rejected. The declaration is the traditional instrument for property matters and is still asked for by many buyers' representatives, lenders and insurers. HM Land Registry, however, will accept a statement of truth under rule 215A of the Land Registration Rules 2003 in place of a statutory declaration, and publishes forms for the common cases: ST1 for adverse possession, with form ADV1 for registered land or form FR1 for unregistered land, ST2 for adverse possession of a rentcharge, ST3 for lost or destroyed deeds, ST4 for prescriptive easements and ST5 for cancelling a joint proprietor restriction (Practice Guide 73, updated 9 December 2024, checked 20 September 2026). A statement of truth is signed by the maker, with their name printed underneath, and needs no witness at all; it does not need to be administered by an authorised person, which removes an appointment and a fee.
An affidavit is sworn evidence for court proceedings. If your matter is heading to court, a boundary dispute, a claim under the Trusts of Land and Appointment of Trustees Act 1996, the court's rules decide the form, and a declaration prepared for HM Land Registry will not do. Boundary disputes explains where that line falls.

Who can administer a statutory declaration?
The declaration must be made before a person authorised to administer oaths. Under section 18 of the Statutory Declarations Act 1835 that is a justice of the peace, a notary public or another officer authorised by law to administer an oath, and today it means anyone authorised for that reserved legal activity under the Legal Services Act 2007. Administering oaths is a reserved legal activity in its own right, defined in Schedule 2 paragraph 8 of that Act as the exercise of the powers of a commissioner for oaths, so a commissioner for oaths and an authorised person are not two different things. Licensed conveyancers are among those who can hold that authorisation, because the Council for Licensed Conveyancers is one of the approved regulators for it under Schedule 4 Part 1 (checked 19 September 2026). The person administering it does not check that the contents are true; they confirm that you declared it before them, on the date shown, and they mark the exhibits. That is why the drafting matters more than the appointment.
We do not administer our own clients' declarations. That is a choice we make rather than a rule imposed on us. We draft, assemble the exhibits, and book the appointment with an authorised person near you who is independent of the matter, because an independent appointment is one less thing for anyone to argue about later. Where a statement of truth will serve, we tell you, because it saves both the appointment and the fee.
