Adverse possession
Description

In general, a property owner has the right to recover possession of their property from unauthorised possessors through legal action such as ejectment. However, many legal systems courts recognize that once someone has occupied property without permission for a significant period of time without the property owner exercising their right to recover their property, not only is the original owner prevented from exercising their right to eject, but a new title to the property "springs up" in the adverse possessor. In effect, the adverse possessor becomes the property's new owner. Over time, legislatures created statutes of limitations setting a time limit for how long owners have to recover possession of their property from adverse possessors. In the United States, for example, these limitation periods vary widely between individual states, ranging from five years to 40 years for real property, or three to five years for personal property.
