North Carolina is a no-fault state when it comes to ending a marriage, but alimony works differently. An affair before separation can bar you from receiving alimony entirely.If your spouse had the affair, the law can require that spouse to pay alimony regardless of the other factors a judge would normally weigh (N.C.G.S. § 50-16.3A).
Alimony does not simply run forever once it starts, either. It ends automatically if the receiving spouse remarries, or if that spouse begins living with a new partner in a relationship that resembles a marriage (N.C.G.S. § 50-16.9). That single rule catches a lot of people off guard, and proving or disproving cohabitation often turns into its own fight inside the larger case.
