Wyoming Mechanics Lien Statutes: Deadlines, Venues & Citations
Where Wyoming liens are filed and enforced
A Wyoming mechanics lien is filed with the County Clerk in the county where the project sits — 120 days from last date of furnishing. Filing in the wrong county does not perfect the claim, which matters on projects that straddle county lines. Those are two different clocks against two different offices, and Wyoming claimants lose rights far more often by missing the second one than the first.
Wyoming deadlines by claimant role
For general contractors: Record the lien — 150 days from last furnishing (Wyo. Stat. Ann. § 29-2-109). For subcontractors and suppliers: Record the lien — 150 days from last furnishing (Wyo. Stat.
