Wyoming Mechanic Lien Law Overview
Last updated June 2026 · Reviewed by Thomas Emalfarb, Esq.
Wyoming construction mechanic lien rights are governed by Wyo. Stat. §29-2-101 et seq. This statutory framework provides mechanic's lien rights to contractors, subcontractors, and material suppliers who furnish labor or materials for the improvement of real property in the State of Wyoming. The statute establishes the procedures for perfecting a mechanic lien, including specific notice obligations and filing deadlines.
Wyoming does not require general contractors to serve a preliminary notice before filing a mechanic lien. However, subcontractors and suppliers on commercial projects must provide written notice to the property owner within 30 days of first furnishing labor or materials. This notice requirement helps ensure that property owners are aware of all parties furnishing labor or materials to the project.
All claimants must perfect their mechanic lien by filing a mechanic lien statement within 150 days of the date of last furnishing labor or materials. Enforcement suits must be commenced within 180 days of the date the mechanic lien was filed. Wyoming's relatively generous filing window provides claimants with meaningful time to resolve payment disputes before resorting to mechanic lien filings.
For public works projects, Wyo. Stat. §16-6-112 et seq. governs the payment bond and Wyo. Stat. §16-6-121 governs the bond-protection notice. Subcontractors and suppliers not in privity with the general contractor must give written notice to the general contractor within 60 days of first furnishing. Suit on the bond must be commenced within 1 year after first publication of the notice of final payment on state Department of Administration and Information projects; on other public projects, the language of the bond controls. National Lien & Bond provides attorney-network compliance and recovery services to help Wyoming construction professionals protect their payment rights.
