N.C. Gen. Stat. § 7B-1806
The summons and petition shall be personally served upon the parent, the guardian, or custodian and the juvenile not less than five days prior to the date of the scheduled hearing. The time for service may be waived in the discretion of the court. A law enforcement officer or juvenile court counselor may serve and complete juvenile process under this section and as provided in G.S. 143B-831. A defense of lack of personal jurisdiction or insufficiency of service of process is waived if a parent, guardian, or custodian and juvenile avail themselves to the court and an objection is not raised at the initial court appearance.
If the parent, guardian, or custodian entitled to receive a summons cannot be found by a diligent effort, the court may authorize service of the summons and petition by mail or by publication. The cost of the service by publication shall be advanced by the petitioner and may be charged as court costs as the court may direct.
The court may issue a show cause order for contempt against a parent, guardian, or custodian who is personally served and fails without reasonable cause to appear and to bring the juvenile before the court.
The provisions of G.S. 15A-301(a), (c), (d), and (e) relating to criminal process apply to juvenile process; provided the period of time for return of an unserved summons is 30 days.
