N.C. Gen. Stat. § 7A-293
A magistrate assigned to an incorporated municipality, the boundaries of which lie in more than one county of a district court district, may, in criminal matters, exercise the powers granted by G.S. 7A-273 as if the corporate limits plus the territory embraced within a distance of one mile in all directions therefrom were located wholly within the magistrate's county of appointment. Appeals from a magistrate exercising the authority granted by this section shall be taken in the district court in the county in which the offense was committed. A magistrate exercising the special authority granted by this section shall transmit all records, reports, and monies collected to the clerk of the superior court of the county in which the offense was committed. In addition, if a magistrate is assigned to an incorporated municipality, the boundaries of which lie in two or more district court districts, the magistrate may exercise the powers described in this section as if the counties were in the same district court district, if the clerks of superior court and the chief district court judges serving the districts in which the municipality is located agree in writing that the exercise of this special authority would promote the administration of justice in the municipality and in the districts. However, if a magistrate is assigned to an incorporated municipality, the boundaries of which lie in four or more counties, each of which is in a separate district court district, the magistrate may exercise the powers described in this section as if all the counties were in the same district court district, without the necessity of such an agreement between the clerks and judges of the affected counties, and the records, reports, and monies collected in connection with the exercise of that authority shall be transmitted to the clerk of the superior court district for the county in which the offense was committed.
