N.C. Gen. Stat. § 50-9

In all cases upon an action for a divorce absolute, where judgment of divorce has heretofore been granted and where the plaintiff has caused to be served upon the defendant in person a legal summons, whether by verified complaint or unverified complaint, and such defendant answered such summons, and where the trial of said action was duly and legally had in all other respects and judgments rendered by a judge of the superior court upon issues answered by a judge and jury, in accordance with law, such judgments are hereby declared to have the same force and effect as any judgment upon an action for divorce otherwise had legally and regularly.
