Most cases of adverse possession deal with boundary line disputes between two parties who hold clear title to their property. The term "squatter's rights" has no precise and fixed legal meaning. In some jurisdictions the term refers to temporary rights available to squatters that prevent them, in some circumstances, from being removed from property without due process. For example, in England and Wales reference is usually to section 6 of the Criminal Law Act 1977. In the United States, no ownership rights are created by mere possession, and a squatter may only take possession through adverse possession if the squatter can prove all elements of an adverse possession claim for the jurisdiction in which the property is located.
