Wyoming lien waiver requirements

Wyoming is a statutory-form state

Wyoming prescribes a mandatory statutory lien waiver form by statute (Wyo. Stat. § 29-10-101(b)), which must be completed in "substantially the following form." There is only one statutory waiver form (no separate conditional vs. unconditional or progress vs. final versions), and it functions effectively as an unconditional release in consideration of payment received to date, while preserving rights to withheld retainage and unpaid amounts. The form includes a notary acknowledgment block, and Wyoming is one of only a few states that requires lien waivers to be notarized to be valid.

Statute: Wyo. Stat. § 29-10-101 (lien waiver form); lien deadlines under Wyo. Stat. §§ 29-2-106, 29-2-107, 29-2-112 (Revised Wyoming Statutory Lien Act)

Requirements at a glance

Notarization: The statutory waiver form in Wyo. Stat. § 29-10-101(b) ends with a notary acknowledgment block ("This instrument was acknowledged before me..."), and Wyoming is widely cited (along with Mississippi, and formerly Texas) as one of the few states requiring lien waivers to be notarized; an un-notarized waiver is generally treated as ineffective.
Mandatory statutory language: Wyo. Stat. § 29-10-101(b) requires the lien waiver to be completed "in substantially the following form" and sets out the specific statutory language (including the "In consideration of the PAYMENT received to date... waive, release, and relinquish" wording and the dishonored-funds acknowledgment). Use the statutory form with substantial compliance; do not materially alter the prescribed language.

Key Wyoming deadlines

Preliminary / pre-lien notice: Yes — preliminary notice of right to lien is required to preserve lien rights (Wyo. Stat. § 29-2-112). The general/prime contractor must send it before receiving any payment from the owner (including advances); subcontractors and materialmen must send it within 30 days after first furnishing labor or materials. Failure to send it bars lien rights.
Notice of intent to lien: Yes — a notice of intention to file lien must be sent to the record owner (or agent) no later than 20 days prior to filing the lien statement (Wyo. Stat. § 29-2-107).
Mechanics lien filing deadline: General/prime contractors: within 150 days; all other claimants (subcontractors, materialmen): within 120 days — measured from the earlier of the last day work/materials were furnished under contract or the date of substantial completion (Wyo. Stat. § 29-2-106). (An owner-recorded notice of substantial completion can fix the start date.)

Wyoming lien waiver FAQ

Does Wyoming require a specific lien waiver form?

Yes. Wyoming prescribes a statutory lien waiver form in Wyo. Stat. § 29-10-101(b), which must be completed in "substantially the following form." There is a single statutory form (no separate conditional/unconditional or progress/final versions), so the prescribed statutory language should be used.

Do lien waivers need to be notarized in Wyoming?

Yes. The statutory waiver form includes a notary acknowledgment block, and Wyoming is one of the few states that requires lien waivers to be notarized to be valid; an un-notarized waiver is generally ineffective.

Can lien waivers be signed electronically in Wyoming?

Yes. Electronic signatures are valid under the federal E-SIGN Act and Wyoming's UETA, but because the waiver must be notarized, the signing must be paired with notarization — Wyoming permits remote online notarization (Wyo. Stat. § 32-3-111), so e-signed waivers can be notarized electronically/online.

What is the deadline to file a mechanics lien in Wyoming?

General (prime) contractors must file within 150 days, and all other claimants (subcontractors and materialmen) within 120 days, measured from the earlier of the last day labor/materials were furnished under contract or the date of substantial completion (Wyo. Stat. § 29-2-106). A separate notice of intent must be sent at least 20 days before filing.
