All liability claims against the fund must be audited by the commissioner, and such audit must be approved by the attorney general. The commissioner has the authority to prescribe the forms upon which claims must be presented and may administer oaths and examine witnesses in connection with claims presented to the commissioner. If the commissioner, with the approval of the attorney general, finds a claim or any part thereof to be a valid, just, and proper charge against the fund, the commissioner shall make and file an order to that effect and state therein the amount allowed upon the claim. A brief description of every claim filed against the fund must be entered by the commissioner in a register provided for that purpose showing the name of the claimant, the amount and character of the claim, the action taken upon the claim, and the date when such action was taken.
