Georgia Code Title 9. Civil Practice § 9-7-22

(a) The fees of an auditor to whom a case, whether legal or equitable, has been referred shall be determined and fixed by the trial judge making the referral or by any other judge having jurisdiction of the case and serving in the place and stead of the trial judge. The fees so determined and fixed may be apportioned between and among the parties at the discretion of the judge.

(b) The court with consent of the parties may fix the fees of the auditor in advance and incorporate the same in the order making the appointment.

(c) The fees of an auditor, as determined and fixed by the judge, shall be included in and made a part of the judgment of the court. The fees of the auditor shall be assessed as court costs and shall be paid prior to the filing of any appeal from the judgment of the court; provided, however, that if such fees have not been determined and assessed at the time of filing any such appeal, the same shall be paid within 30 days from the date of assessment.
