Wyo. Stat. § 9-4-304 (2026)

No monies deposited in the state treasury for the purposes
specified in W.S. 9-4-303(b) and 9-4-306 shall be expended or
disbursed except upon itemized claims, and the itemized claims
shall be approved for payment by the respective boards of
trustees, or other boards or officers under whose authority the
monies are by law authorized to be disbursed. The itemized
claims shall then be audited by the state auditor, who, if
satisfied that the monies are being properly disbursed according
to law, shall issue his warrant for the amounts of the claims.
The warrants shall be paid by the state treasurer out of the
particular fund or account on which the warrants are drawn.
