How to Stop an Adverse Possession Claim in the UK (Landowner Defences)

Statutory Source: Land Registration Act 2002 (Schedule 6 Paragraph 3) & Land Registration Rules 2003

Quick Answer: How to Stop an Adverse Possession Claim in the UK (Landowner Defences)

Landowners can stop an adverse possession claim using three primary legal defences: (1) File a formal Counter-Notice (Form NAP) with HM Land Registry within 65 business days of receiving notice under Schedule 6, which automatically defeats standard registered land claims, (2) Grant a written, revocable licence or formal tenancy—under English law, possession with permission or consent is never 'adverse' and immediately stops the clock, or (3) Issue formal court possession proceedings (Part 55 CPR) before the 10-year or 12-year limitation period expires.

The 3 Primary Landowner Defences Under Schedule 6

If you are a registered landowner faced with a squatter or neighbouring homeowner attempting to claim your land:

Defence 1: The Form NAP Counter-Notice (The Ultimate Registered Shield). When HM Land Registry notifies you of Form ADV1, you have 65 business days to reply using Form NAP. Under Paragraph 3 of Schedule 6, filing a counter-notice forces Land Registry to immediately reject the application unless the applicant can prove one of the three narrow exceptions.

Defence 2: Express Written Licence or Tenancy. Under the nec precario doctrine, adverse possession cannot exist if the occupier holds permission. Sending a registered letter formally granting a free, revocable licence to maintain the land destroys their adverse claim immediately.

Defence 3: Court Possession Action. Under Section 15 Limitation Act 1980, issuing a claim for possession in the County Court stops time running from the date proceedings are issued.

Critical Warning: Keeping Your Land Registry Address Updated

Under Section 79 of the Land Registration Act 2002, HM Land Registry is only required to serve notice to the address recorded on your Title Register.

If you moved home or left an outdated correspondence address on title, Land Registry notices will be delivered to the old address. If the 65 business days expire without a Form NAP response, Land Registry will register the squatter as owner, and you will lose your land permanently.
