N.C. Gen. Stat. § 15A-1365

When a defendant has defaulted in payment of a fine or costs, the judge may order that the judgment be docketed. Upon being docketed, the judgment becomes a lien on the real estate of the defendant in the same manner as do judgments in civil actions. Executions on docketed judgments may be stayed only when an appeal is taken and security is given as required in civil cases. If the judgment is affirmed on appeal to the appellate division, the clerk of the superior court, on receipt of the certificate from the appellate division, must issue execution on the judgment. The clerk may not issue an execution, however, if the fine or costs were imposed for an offense other than trafficking in controlled substances or conspiring to traffic in controlled substances under G.S. 90-95(h) and (i), respectively, and the defendant elects to serve the suspended sentence, if any, or serve a term of 30 days, if no suspended sentence was imposed.
