Okla. Stat. tit. 58 § 282
To make the appraisement, the judge must appoint three disinterested persons, any two of whom may act, who are entitled to receive a reasonable compensation for their services, not to exceed Seventy-five Dollars ($75.00) per day, except upon order of the court. The appraisers must, with the inventory, file a verified account of their services and disbursements. If any part of the estate is in any other county, the same appraisers may proceed to view and appraise the same, or other appraisers in that county may be appointed to perform that duty, by the judge of the district court of the county in which the letters were issued, as he may deem best; and the like report must be made in each case direct to the district court of the county which issued the letters.
