A probate referee who appraises property in the estate shall, upon demand by the personal representative or by a beneficiary:
(a)
Provide any appraisal report or backup data in the possession of the probate referee used by the referee to appraise an item of property. The probate referee shall not disclose any information that is required by law to be confidential. The probate referee shall provide the appraisal report or backup data without charge. The cost of providing the appraisal report or backup data shall not be allowed as an expense of appraisal but is included in the commission for services of the probate referee.
(b)
Justify the appraisal of an item of property if the appraisal is contested, whether by objection pursuant to Section 8906, by tax audit, or otherwise. The probate referee may be entitled to an additional fee for services provided to justify the appraisal, to be agreed upon by the personal representative or beneficiary and referee. If the personal representative or beneficiary and the probate referee are unable to agree, the court shall determine what fee, if any, is appropriate.
