Said appointed special master shall keep a record of the case, which shall be kept with and constitute a part of the records of said court, all of which shall be approved by the judge of said court before the order is issued.II.Compensation. Such master or special master when sitting as master shall be allowed per diem compensation determined by the supreme court upon recommendation by the judicial branch administrative council, established pursuant to supreme court rule, plus reasonable expenses. If the parties are indigent, the probate court, in its discretion, may assess such charges against the state; provided, however, that all bills submitted by the master for compensation shall first be submitted to the probate judge for approval.
