Title to land can be acquired by holding it adversely to the true owner for a certain period of time. In this case, the person in possession gains title by adverse possession. The person in possession automatically becomes the owner of the property even though the person had no lawful claim to the land. In order to acquire title in this manner, possession must be actual, visible, exclusive, and continuous for a period of time. In some states, the period of time is ten years. However, state statutes vary with regard to this period of time.
