In old times, there were laws on the books that defined a cause of action called "Alienation of Affections" which, among other things, allowed an aggrieved spouse to sue their spouse's illicit lover. One US state (North Carolina) still has AOA laws on the books and there are still cases brought on these grounds
Is there a similar concept in Judaism? Obviously in Judaism, adultery is a criminal matter, but suppose someone outside the marriage committed an emotional adultery or otherwise turned spouses against one another, destroying their marriage but without any physical transgression. Are there legal remedies in Halacha?
