The board may adopt forms for the submission and payment of claims and may prescribe and adopt warrant forms separate from claim forms, to the end that the approved claims may be retained in the auditor’s office as vouchers supporting the warrants issued. The forms so adopted may not be inconsistent with the provisions of this article or of any other statutes or regulations expressly governing any such claims or the presentation thereof, and shall provide:
(a)
For the approval of the officer directing the expenditure. In counties having a system under which expenditures may be initiated by requisition, the approval may be omitted from claims initiated by requisition.
(b)
For the approval of the purchasing agent or other officers issuing the purchase order under which the charge was incurred, or having charge of contracts or schedules of salaries under which the claim arose.
(c)
For the approval of at least one member of the board. In lieu of the supervisor’s approval on each claim there may be substituted duplicate lists of claims allowed, showing, as to each claim, the name of the claimant, the amount allowed, and the date of allowance. The lists shall be certified to the board by the clerk of the board or other competent officer or employee designated by it for the purpose, as being a true list of claims properly and regularly coming before the board. Upon allowance of claims each of the lists, after amendment if necessary, shall be certified to as having been allowed by the board, the date allowed, and that such lists are correct by one member of the board or by the clerk of the board and filed, one in the office of the clerk of the board and one in the office of the auditor. When filed the lists constitute respectively the “allowance book” and the “warrant book.” If the allowance book is dispensed with by the board of supervisors under the authority of Section 25102, a single list of claims may be substituted in lieu of a supervisor’s approval on each claim, which list shall be processed and certified as required for duplicate lists and shall be filed in the office of the county auditor as the warrant book.
(d)
For the certificate of the clerk of the board as to the date and amount of allowance of the claim by the board. If the duplicate lists of claims allowed are filed, the certificate may be omitted, but in its stead there shall appear on each claim a reference by date, number, or otherwise to the list on which the claim appears listed as allowed.
(e)
For the certificate of the clerk of the board or of the auditor as to the correctness of the computations.
(f)
For the auditor’s approval.
