How Long Does Adverse Possession Take to Process at HM Land Registry?

Statutory Source: Land Registration Act 2002 (Schedule 6) & Land Registration Rules 2003

Quick Answer: How Long Does Adverse Possession Take to Process at HM Land Registry?

HM Land Registry typically takes between 6 to 18 months to process an adverse possession application (Form ADV1 for registered land or Form FR1 for unregistered land). The procedure entails: (1) Preliminary document examination and title check (2–4 months), (2) Commissioning an Ordnance Survey site inspection survey (1–2 months), (3) Mandatory statutory notice service to the registered owner with a 65-business-day counter-notice window, and (4) If disputed, referral to the Land Registration Division of the First-tier Tribunal (Property Chamber), adding 9 to 15 months.

Step-by-Step HM Land Registry Processing Stages

Applying for adverse possession under Schedule 6 of the Land Registration Act 2002 involves four distinct statutory phases:

Stage 1: Initial Caseworker Examination. Land Registry examiners review Form ADV1, Form ST1 (Statement of Truth), and supporting historical evidence (photographs, contractor invoices, statutory declarations).

Stage 2: Ordnance Survey Boundary Survey. Land Registry usually instructs an Ordnance Survey surveyor to visit the land, verify physical fencing and lockable gating, and produce an official OS Boundary Report.

Stage 3: Service of Notice (The 65-Day Window). Under Rule 189 of the Land Registration Rules 2003, HM Land Registry serves formal notice on the registered proprietor, chargees (mortgage lenders), and interested parties. Recipients have 65 business days to serve a Counter-Notice (Form NAP).

Stage 4: Resolution or Registration. If no counter-notice is received, the applicant is registered with possessory title. If an objection is lodged, the case proceeds to negotiation or the Tribunal.

Expedition Requests for Conveyancing Deadlines

HM Land Registry offers an 'Expedite' service if a pending property sale or mortgage refinance is at risk of falling through.

To request expedition, your conveyancer must submit proof of the impending contract exchange or mortgage offer expiry date. While expedition accelerates internal caseworker processing, it cannot legally shorten the mandatory 65-business-day statutory notice period.
