Adverse Possession，法律术语，指时效占有；逆权侵占；无合法所有权之占有时效占有。

Adverse Possession：the acquisition of property by a trespasser whose occupation of the property is exclusive,open,and continuous for a statutory period.

A means to acquire title to land through obvious occupancy of the land, while claiming ownership for the period of years set by the law of the state where the property exists. This can arise when a rancher fences in a parcel contending he was to get title from some prior owner, and then grazes cattle on the property for many years without objection by the title holder. Payment of real property taxes and making improvements (such as paving or fencing) for the statutory period (varies by state) are evidence of adverse possession but cannot be used by a land grabber with no claim to title other than possession.

Laws of Adverse Possession，时效占有法，又称“占屋者权利”（squatters right），是指有人非法占有一处房产10年以上，法律就承认此人对此间房屋的所有权。（主要是美国这类发达国家才有类似法律）。
