Alienation of affection(s) is a legal action, a tort based on willful and malicious interference with marriage relations by a third party. The elements constituting the cause of action are wrongful conduct of the defendant, plaintiff’s loss of affection or consortium of spouse, and a causal connection between the two. Not all states recognize the right to bring an alienation of affections action. It is usually viewed as not being relevant or easily applied in modern society.
