If this means that they are committing adultery, then yes. Alienation of Affection is still a viable civil cause of action in NC. You can also be granted a divorce on the grounds of adultery. Adultery is an absolute bar to alimony in NC. However, if you stay together with your wife and continue to cohabitate after gaining knowledge of the adulterous activity, your wife can claim the defense of condonation (forgiveness). You must separate in order to file for divorce and adultery.
