Free Lien Waiver Forms -- Conditional & Unconditional, Fill & Sign Online

What is a lien waiver?

A lien waiver is a legal document signed by a contractor, subcontractor, or material supplier that releases their right to file a mechanics lien against a property in exchange for payment. General contractors and property owners routinely require lien waivers before issuing progress and final payments to protect against double-payment liability.

In California, lien waivers are governed by Civil Code sections 8132 through 8138, which mandate four specific statutory forms. Using a non-statutory waiver -- or the wrong form for the situation -- can render the waiver unenforceable, exposing the paying party to a valid lien claim even after payment. Our templates match the California Civil Code requirements exactly.

Mechanics liens are the backstop that gives unpaid contractors, subcontractors, and suppliers leverage on a construction project. A lien clouds the property title and can force the owner to resolve the payment dispute before selling or refinancing. Lien waivers are how the chain of payment releases that risk at each pay event.

Conditional vs. unconditional lien waivers

The most important distinction in lien waiver law is conditional vs. unconditional -- it determines when the waiver becomes legally effective.

Conditional waiver -- becomes effective only when the specific check clears the bank. The claimant can still file a lien if the check bounces or is stopped. Use a conditional waiver at the time you receive a check, before you have confirmed the funds are in your account. Under California Civil Code §8132 (conditional progress) and §8136 (conditional final), the waiver is conditioned on receipt of the identified payment.

An unconditional waiver takes effect immediately upon signing, with no conditions attached. Because lien rights are surrendered instantly, use an unconditional waiver only after payment has cleared and you have confirmed the funds. Civil Code §8134 (unconditional progress) and §8138 (unconditional final) govern these forms.

Progress vs. final lien waivers

A progress waiver covers a portion of the work -- it releases lien rights for work completed and paid through a specific date, not the entire project. Use a progress waiver each time you receive a progress payment during a construction project.

A final waiver releases all lien rights for the entire project, including work not covered by prior waivers. Exchange the final waiver for final payment only after confirming you have been paid in full. Signing a final unconditional waiver before final payment clears is one of the most common costly mistakes in construction payment.

Frequently asked questions

Do California lien waivers need to be notarized?

No. California Civil Code does not require notarization for lien waivers. The statutory forms require only the claimant's signature and the relevant payment details.

Can I use a lien waiver form from another state in California?

No. California mandates its own statutory forms (CC §8132, §8134, §8136, §8138). A non-statutory or out-of-state waiver form is not enforceable as a lien waiver in California.

When should I use a conditional vs. unconditional waiver?

Use a conditional waiver when you receive the check but before it clears. Use an unconditional waiver only after the funds have cleared your bank account and you are certain payment is complete.

Is an electronic signature valid on a California lien waiver?

Yes. Electronic signatures are legally valid under California law and the federal ESIGN Act. The statutory forms require a signature but do not specify wet ink.
