N.C. Gen. Stat. § 65-95
In lieu of the provisions of this section, the clerk may appoint any bank or trust company authorized to do business in this State as trustee for the funds authorized to be paid into his office by virtue of this Part; provided, that no bank or trust company shall be appointed as such trustee unless such bank or trust company is authorized and licensed to act as fiduciary under the laws of this State.
Before any clerk shall turn over such funds to the trustee so appointed, the clerk shall require that the trustee so named qualify before the clerk as such trustee in the same way and manner and to the same extent as guardians are by law required to so qualify. After such trustee has qualified as herein provided, all such funds coming into the clerk's hands may be invested by the trustee only in the securities set out in G.S. 7A-112 and the income therefrom invested for the purposes and in the manner heretofore set out in this Part. All trustees appointed under the provisions of this Part shall render and file in the office of the clerk of the superior court all reports that are now required by law of guardians.
