Wyoming Lien Waiver Requirements: What General Contractors Need to Know

Is Wyoming a Statutory Lien Waiver State?

Yes. Wyoming is a statutory lien waiver state under Wyoming Statutes Section 29-10-101. Wyoming provides a single statutory lien waiver form that functions as an unconditional waiver for the amounts noted in the document. Wyoming is one of only three states that requires lien waivers to be notarized in order to be legally valid. For context on how Wyoming compares to other statutory states, see our guides for Texas, California, and Arizona.

Wyoming's Single Statutory Form

Unlike most statutory states that provide four waiver forms, Wyoming provides only one. The statutory form functions as an unconditional waiver — it states that the signing party acknowledges receipt of payment for work performed or materials provided. Because the form is unconditional in nature it should only be signed after confirming that payment has actually been received and cleared.

Wyoming's Notarization Requirement

A lien waiver that is not notarized is not legally valid in Wyoming regardless of whether the correct statutory form was used. Every lien waiver signed on a Wyoming project must be notarized by a licensed notary public at the time of signing. Failure to notarize a lien waiver in Wyoming means the waiver is unenforceable and lien rights are not released. Electronic signatures without notarization do not satisfy Wyoming's requirements.

Wyoming's Preliminary Notice Requirement

Subcontractors and suppliers who do not have a direct contract with the property owner must serve a preliminary notice on the owner to preserve their lien rights. Track which parties have served preliminary notices on each Wyoming project. Parties who have properly served notice have preserved their lien rights and you need their signed, notarized waiver before your project is fully protected.

Wyoming Lien Filing Deadlines

A subcontractor or supplier must file a lien within 120 days of the last day they furnished labor or materials to the project. Missing this deadline means losing lien rights permanently. Collecting notarized waivers at every payment creates a documented record that directly contradicts any subsequent lien claim.

Common Wyoming Lien Waiver Mistakes

Failing to notarize waivers is the most critical and most common mistake on Wyoming projects. Without notarization the waiver is void regardless of the form used. Using the wrong form is another serious error. Collecting waivers before payment clears is risky given the unconditional nature of Wyoming's statutory form — always confirm receipt of funds before requesting the signature.

How to Stay Compliant on Wyoming Projects

Use only Wyoming's statutory waiver form. Ensure every waiver is notarized at the time of signing — build notarization into your standard process, not as an afterthought. Track preliminary notices from day one. Release payment only after confirming receipt and ensure the waiver is properly notarized before relying on it as protection. A documented closeout process that accounts for Wyoming's notarization requirement is the difference between a protected project and an exposed one.
