Good to know

A claimant must prove enclosure or cultivation by clear and convincing evidence.

What this means in practice

Courts usually require possession that is actual, open, continuous, exclusive and hostile (without the owner's permission) for the full statutory period. The person claiming the land generally has to prove each element, and courts read these requirements strictly.

Owners can protect themselves by inspecting vacant or rural land regularly, keeping boundary lines marked, and responding quickly to fences, buildings or other uses that cross the line. Written permission, such as a simple license or lease, can make a neighbor's use permissive instead of hostile.

Adverse possession does not usually transfer title automatically. The occupant often needs a court judgment, such as in a quiet title action, before the new ownership can be recorded. Boundary disputes between neighbors are often settled with a survey and a recorded deed instead of a lawsuit.

General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
