ejectment
n. a lawsuit brought to remove a party who is occupying real property. This is not the same as an unlawful detainer (eviction) suit against a non-paying or unsatisfactory tenant. It is against someone who has tried to claim title to the property. Example: George Grabby lives on a ranch which he claims he has inherited from his great uncle, but Betty Benefield sues for ejectment on the basis that, in fact, she was entitled to the property through her parents.
