Yes. Arizona Revised Statutes §15-321 requires board members to review and authorize vouchers and the related expenditures before processing and payment.
The statute allows board members to sign expenditures between board meetings, provided that, prior to the signing, the board has passed a resolution to use that procedure. When board members approve expenditures between meetings, the board must ratify the expenditures in its next regular or special meeting. Ratification is not the first approval, but the formal action taken to document the board approval obtained between meetings.
District policy may allow an electronic approval process. Districts should consult their legal counsel and authorized county personnel for satisfactory methods to document board members’ signatures, such as faxed documents; electronic approval software; preauthorized, dedicated email addresses; or another agreed-upon method.
