AP1 form: how to apply to HM Land Registry to change the register
Any time you need to change who owns a property — removing a deceased person from a joint title, transferring it to a beneficiary, or making a restriction — you file AP1 to make that application to HM Land Registry.
AP1 itself just identifies the application; the actual change is effected by the form lodged with it (DJP, AS1, TR1, or RX1).
This walkthrough explains how to complete AP1, what supporting documents must accompany it, how the fee is calculated, and how the OS1 official search protects your application.

This walkthrough takes AP1 field by field, in plain English. AP1 is just the envelope; the real change to the register is in the form lodged with it — DJP to remove a deceased joint owner, AS1 to assent property to a beneficiary, TR1 to sell. The hard part is knowing which of those applies, and protecting your place in the queue with an OS1 search before you send it.
The step people skip that loses their place in the queue
Lodging AP1 without a current OS1 official search.
The OS1 search provides a 'priority period' during which no other application against the same title can jump ahead of yours.
Without an OS1, you have no protection against a competing application — for example, if the deceased's estate had unknown creditors who might register a restriction.
The OS1 search costs £3–7 and takes a day; it should always be obtained immediately before submitting AP1.

AP1 is the Land Registry's standard application form for registering any dealing with a registered title — including transfers, assents, restriction entries, charges, and removing deceased proprietors.
AP1 is not a standalone transaction: it is submitted alongside the relevant substantive form (DJP for removing a deceased joint owner, AS1 for an assent to a beneficiary, TR1 for a transfer, RX1 for a restriction).
Without a valid AP1, HMLR will not process the supporting documents.
AP1 identifies the title, the applicant, the priority period from the OS1 search (which protects the application), and the fee payable.

Section 1
AP1 and the forms it accompanies — the gateway concept
AP1 is the envelope, not the letter.
The actual instruction to HMLR is in the substantive form — DJP, AS1, TR1, or RX1. AP1 identifies the title, the parties, and the fee. Understanding which substantive form applies to your situation is the first step.
01
DJP — removing a deceased joint proprietor
When a property was held by two or more joint tenants and one has died, the DJP is lodged with AP1.
The surviving joint owner remains as sole proprietor.
The fee is nil.
Required supporting documents: official copy death certificate or a certified copy.
02
AS1 — assenting property to a beneficiary
When the executor or administrator transfers the property to a named beneficiary under the will or intestacy, AS1 is lodged with AP1.
Required documents: grant of probate or letters of administration (certified copy); AS1 signed by the executor(s); identity verification for the executor under ID1 or ID2 form.
Fee: nil for nil-consideration assents.
03
TR1 — selling the property
When the property is sold (either by the estate to a buyer, or by a beneficiary who has received it), TR1 is lodged with AP1.
This is a standard conveyance.
The buyer's solicitor typically handles AP1 at the point of purchase.
04
RX1 — entering a restriction
When beneficiaries wish to protect a beneficial interest (for example, recording that two beneficiaries own the property as tenants in common in specific shares), RX1 and a Form A restriction are lodged with AP1.
This is standard when a property passes jointly to multiple beneficiaries.
AP1 is the envelope, not the letter.

§22
Section 2
Completing AP1
AP1 is straightforward once you have the title register and know the nature of your application.
The title register (available online for £3 at gov.uk/search-property-information-land-registry) contains most of the information you need.
01
Panel 1 — title number and property address
Enter the title number from the Land Registry title register (format: e.g. GL456789 for a Greater London title).
This is not the same as the property address, postcode, or mortgage account number.
It is a unique registration identifier found at the top of the title register document.
02
Panel 2 — application type
Tick the relevant application type(s).
For an estate application you will typically tick 'Transfer' (if using TR1 or AS1) or 'Remove deceased proprietor' (if using DJP).
If you are also entering a restriction, add 'Restriction' to the application.
03
Panel 3 — priority search reference
Enter the reference number from the OS1 official search obtained before submitting.
The priority period (30 working days) within which you must lodge AP1 is shown on the OS1 certificate.
If the priority period has expired, conduct a new OS1 search before lodging.
04
Panel 4 — fee
Use the HMLR fee calculator to determine the fee.
For nil-consideration transfers (DJP, assent of property to beneficiary at nil consideration), the fee is nil.
For sales, the fee is scaled to the consideration.
Payment by cheque (made payable to HM Land Registry) or by HMLR fee account if the application is made by a solicitor.
05
Panel 5 — applicants' details and identity
Name and address of the applicant (the executor, or their solicitor).
All executors must be identified.
For private individuals (not solicitors), the executor must verify their identity using form ID1 (verified by a professional — solicitor, accountant, bank) or ID2 (verified in person at a Post Office or conveyancer).
AP1 is straightforward once you have the title register and know the nature of your application.

Section03
§33
Section 3
The OS1 official search — protecting the application
Before lodging AP1, always obtain an OS1 official search against the title.
The OS1 search grants a priority period of 30 working days. During this window, HMLR will not process any application against the title that has a later search date than yours.
01
Why priority matters
If a creditor of the estate, a beneficiary's ex-spouse, or a fraudster registers something against the title between you and HMLR processing your application, it could jump ahead of your client's acquisition.
The OS1 search prevents this.
In practice, for straightforward estate administrations, competing applications are rare — but the £3–7 search fee is trivially cheap protection.
02
How to obtain OS1
Apply online at the Land Registry portal (portal.hmlr.gov.uk) or submit form OS1.
You need the title number and the search applicant's details.
The result is provided electronically within 24 hours.
Once you have the priority certificate, lodge AP1 within the 30 working day window.
03
OS2 for leasehold
If the property is leasehold, use OS2 (official search against the leasehold title) in addition to (or instead of) OS1 against the freehold title.
Check the title register — it will show whether the property is freehold (absolute freehold) or leasehold.
Before lodging AP1, always obtain an OS1 official search against the title.

FAQ
AP1 questions, answered.
AP1 is HM Land Registry's standard application form for changing a registered property title.
It is the gateway form for almost any dealing with registered land in an estate — removing a deceased joint owner, assenting a property to a beneficiary, transferring it on a sale, or entering a restriction.
AP1 itself does not make the change: it identifies the title, the applicant, and the fee, and travels alongside the substantive form that actually does the work.
The executor or administrator dealing with the estate, or a solicitor or conveyancer acting for them.
On a sale, the buyer's solicitor usually lodges AP1 at completion.
A lay executor can complete and submit it themselves, but where the application transfers the property (AS1 or TR1) they will also need to verify their identity using form ID1 or ID2.
There is no statutory deadline to register a death-of-proprietor change or an assent — the title can be updated whenever the estate is ready.
The window that matters is the 30-working-day priority period given by the OS1 official search: lodge AP1 within that window and no later application against the same title can jump ahead of yours.
If the window lapses, you simply obtain a fresh OS1 and lodge again.
It depends on the substantive form. Removing a deceased joint proprietor (DJP) is free, and a nil-consideration assent to a beneficiary (AS1) is also free.
A transfer on a sale (TR1) carries a scale fee that rises with the property value under HM Land Registry's Scale 1.
The OS1 official search costs only a few pounds.
Always check HMLR's current fee schedule on gov.uk, as the fee order changes from time to time.
The title number and property details from the Land Registry register (a copy of the register costs a few pounds online); the substantive form for your situation (DJP, AS1, TR1, or RX1); the supporting evidence that form needs — an official copy death certificate for a DJP, or a certified copy grant of probate or letters of administration for an assent; a current OS1 official search certificate; and, for individuals lodging a transfer, completed ID1 or ID2 identity verification.
Lodging AP1 without a current OS1 official search.
The OS1 gives you a 30-working-day priority period during which no competing application — such as a creditor's restriction — can register ahead of you.
Without it, you have no protection while HMLR processes the application.
The search costs only a few pounds and is returned within a day, so it should always be obtained immediately before you submit.

Where this fits
AP1 is one form. The file behind it is the rest.
Forms are easier when the records are ready.
For AP1, that means the title number from the Land Registry register, the substantive form that does the actual work (DJP, AS1, or TR1), the death certificate or grant of probate that supports it, and a current OS1 official search to protect your priority.
