If the piece of property in dispute has been used by someone other than the owner for a number of years, the doctrine of adverse possession may apply. State laws vary with respect to time requirements; however, typically, the possession by the non-owner needs to be open, notorious, and under a claim of right. In some states, the non-owner must also pay the property taxes on the occupied land. A permissive use of property eliminates the ability to claim adverse possession.
