Where the docket shall have been delivered as provided in § 5-2-110, it shall be the duty of the magistrate of the new county to issue executions, scire facias, and such other process as may be necessary for the enforcement of the judgments thereon, to the same extent and in as full a manner as the magistrate of the old county could have done, and it shall be the duty of the county clerk of the new county, upon presentation of any such process, to certify to the official character of the magistrate issuing the execution or other process, and any such process so certified shall have the same force and validity in any other county as is now by law given to such process when issued by a magistrate of an old county and certified by the clerk thereof.
