Generally held to be remnants of an earlier time, tort actions based on the idea of "home wrecking," as it is nostalgically called, require that the plaintiff prove the co-respondent’s wrongful conduct; that the plaintiff lost the affection of his or her spouse as a result; and that a causal connection exists between the defendant’s conduct and the plaintiff’s loss. This must be done to the standard of preponderance of evidence.
