National Provincial Bank Ltd v Ainsworth
National Provincial Bank Ltd v Ainsworth  is an English land law and family law case, concerning the quality of a person's interest in a home when people live together, as well as licenses in land. The House of Lords, the court of final appeal, held that someone living in a home, who was deserted, did not by that fact alone have an interest in equity.
