Wyo. Stat. § 33-24-109
All monies shall be received and collected as provided by law. The state treasurer shall place the money in a separate account. The money shall only be paid out upon a lawful voucher properly accompanied by two (2) signatures authorized by the board showing that the expense has been actually and properly incurred in the performance of the duties devolved upon the board. Upon presentation of the voucher and certificate, the auditor shall draw his warrant upon the treasurer against the account in favor of the proper person. No warrant shall be drawn unless and until there are sufficient monies in the account to pay the same. The account shall only be drawn upon to pay the necessary compensation and expenses of the board, and such expenses as may be necessary to carry out and execute the provisions of this act.
