Wyoming Lien-Waiver Rules
Statutory forms required. Wyoming Statutes § 29-1-311 mandates the waiver form. The statute provides explicit language for three waiver types.

- Partial (Interim) Unconditional Waiver and Release

Wyoming is one of the few states where a lien can attach to severed minerals and timber — and the waiver rules follow that. The scope is broader than most states.
Conditional vs unconditional waivers — the universal rule
When should you sign a waiver in Wyoming?
Only sign a conditional waiver until you have confirmed payment has cleared your bank account. The conditional waiver protects you: it says your lien rights are waived only if the attached payment actually funds. If the check bounces, you keep your lien.
Once payment has confirmed cleared funds, you can sign the unconditional waiver for that payment period. For final payment on a completed project, you'll sign the unconditional final waiver — but only after the full retainer is released and all change orders are paid.
Documenting every progress payment and waiver exchange with a timestamped record is critical — that chain of evidence protects your lien rights. VoiceLogPro's daily logging keeps a date-stamped, time-verifiable record of work performed and payments received.
