Probate Code § 8964
ARTICLE 4. Commission and Expenses of Probate Referee
If more than one probate referee appraises or participates in the appraisal of property in the estate, each is entitled to the share of the commission agreed upon by the referees or, absent an agreement, that the court allows. In no case shall the total commission for all referees exceed the maximum commission that would be allowable for a single referee.
