Ejectment is a common law term for civil action to recover the possession of or title to land.[1] It replaced the old real actions and the various possessory assizes (denoting county-based pleas to local sittings of the courts) where boundary disputes often featured. Though still used in some places, the term is now obsolete in many common law jurisdictions, in which possession and title are sued by the actions of eviction (also called possession proceedings) and quiet title (or injunctive and/or declaratory relief), respectively.
Originally, successful ejectment meant recovery of possession of land, for example against a defaulting tenant or a trespasser, who did not have (or once had no longer did) any right to remain there. It has continued to be used for this, though in some jurisdictions the terminology has changed.
