Wyo. Stat. § 16-6-117
In all contracts entered into by any person with a public entity for a public work, no payments under W.S. 16-6-116(a) shall be made until the person files with the public entity with which the contract has been made, a sworn statement setting forth that all claims for material, supplies and labor performed under the contract have been and are paid for the entire period of time for which the payment is to be made. If any claim for material, supplies or labor is disputed the sworn statement shall so state, and the amount claimed to be due the subcontractor or materialmen may be filed by the claimant as a claim against the general contractor's surety bond. Payment to the general contractor under W.S. 16-6-116(a) shall be paid without regard to any pending claims against the general contractor's surety bond unless the public entity has actual knowledge that the surety bond is deficient to settle known present claims, in which case an amount equal to the disputed claims may be withheld.
