The short answer
Adverse possession is the principle that long, uninterrupted occupation of land that legally belongs to someone else — without their permission — can, in time, give the occupier the right to be registered as the owner. In boundary cases it often arises where a fence has sat in the “wrong” place, or a strip has been used as if it were one owner’s, for many years. The rules are strict and very fact-specific, and there are far more myths about “squatter’s rights” than there are easy successes. Whether a claim works depends entirely on the detailed evidence.
Why it matters
A claim generally requires factual possession (exclusive physical control of the land), an intention to possess it, and that this continued without the owner’s permission for the relevant period. The periods differ:
- Unregistered land — broadly twelve years’ adverse possession under the Limitation Act 1980.
- Registered land — under the Land Registration Act 2002 you can apply after ten years, but the registered owner is notified and can object; you usually succeed only in limited circumstances, notably the boundary condition where you reasonably believed, for at least ten years, that the land was yours.
The 2002 Act deliberately made adverse possession much harder against registered land. And several common beliefs are simply wrong: permission defeats a claim; asking to buy the land can undermine it; and it is rarely quick, easy or automatic. Like every boundary question, it is an evidence dispute — the outcome turns on detailed proof of how the land was used and for how long, not on anecdotes.
What to do now
- If you occupy the land: gather evidence of the nature and length of your use, and take advice before assuming you have a claim.
- If it is your land: act before time runs — object, grant permission in writing, or take steps to recover possession.
- Either way, have the evidence assessed objectively rather than relying on what you have heard.
Common mistakes
- Believing the “squatter’s rights” myths.
- Assuming any long-standing use automatically succeeds.
- As an owner, ignoring an encroachment until the time period has run.
- As an occupier, assuming a claim is straightforward.
