Adverse possession: sometimes called "squatter's rights": is the legal principle that allows a person who has occupied someone else's land openly, continuously, and without the owner's permission for a sufficient period of time to apply to be registered as the legal owner. It is a source of significant disputes between neighbours, particularly over garden boundaries, and understanding how it works is important for any property owner.
Adverse possession is a doctrine that recognises that long, uninterrupted occupation of land can eventually give rise to a legal claim to ownership, even if the occupier has no formal legal title. The doctrine exists to prevent land being left in legal limbo and to reflect the practical reality of long-established occupation.
The time period depends on when the land was registered:
For unregistered land, the old limitation period applies: an adverse possessor can extinguish the paper owner's title after 12 years of adverse possession. This is governed by the Limitation Act 1980.
For registered land (the vast majority of land in England and Wales today), the Land Registration Act 2002 introduced a significantly different regime. After 10 years of adverse possession, the squatter can apply to be registered as owner. However, the Land Registry will notify the registered owner, who then has two years to object. If the owner objects and takes steps to recover the land, the squatter's application fails. Only if the owner takes no action within two years will the squatter's application be allowed.
To establish adverse possession, the claimant must show:
If you receive notification from the Land Registry that someone has applied to register adverse possession over land you own, you must act promptly. You have two years to take action, but the sooner you respond the better. You should:
Adverse possession allows someone who has occupied land continuously and openly for 10 years (registered land) or 12 years (unregistered land) to apply for legal ownership. For registered land, the owner is notified and has two years to object. To succeed in a claim, the occupier must show factual possession, intention to possess, absence of permission, and continuity. If you receive a Land Registry notification, take legal advice and act immediately.
