A judge shall by order of record reject or confirm all orders, judgments and decrees of the commissioner within the time the judge could set aside such orders, judgments or decrees had the same been made by him. If so confirmed, the orders, judgments and decrees shall have the same effect as if made by the judge on the date of their confirmation.

The deputy commissioner shall be appointed for a term of four years. The compensation of the deputy commissioner shall be the same as that of an associate circuit judge, payable in the same manner and from the same source as the compensation of an associate circuit judge. Subject to approval or rejection by the judge of the probate division, the commissioner shall have all the powers and duties of the clerk of the probate division and the judge; but a judge shall by order of record reject or confirm all orders, judgments, and decrees of the deputy commissioner within the time such judge could set aside such orders, judgments, or decrees, had the same been made by him; and if so confirmed such orders, judgments, and decrees shall have the same effect as if made by the judge on the date of such confirmation. In any city not within a county, any deputy commissioner of the probate court may be temporarily assigned by the presiding judge of the circuit court to serve as a family court commissioner.
