California lien waiver requirements

California is one of the strictest states for lien waivers. A waiver must substantially conform to one of the four statutory forms in Civil Code §§8132, 8134, 8136, and 8138 — and a waiver that doesn’t conform is void and unenforceable. There’s no room to draft your own.

This guide explains the four California forms, the conditional-vs-unconditional rule, and what makes a waiver valid. It is general information, not legal advice — confirm specifics with a California construction attorney.

California lien waiver FAQs

Does California require a specific lien waiver form?

Yes. California prescribes four statutory waiver forms in Civil Code §§8132–8138, and a waiver that doesn’t substantially conform to the correct form is void and unenforceable. Both sides should stick to the statutory templates.

What are the four California lien waiver forms?

Conditional waiver and release on a progress payment (§8132), unconditional on a progress payment (§8134), conditional on final payment (§8136), and unconditional on final payment (§8138).

What’s the difference between conditional and unconditional in California?

A conditional waiver takes effect only once payment actually clears, so it’s safe to exchange before payment. An unconditional waiver takes effect on signing regardless of payment — sign it only after you’ve been paid.

Do California lien waivers need to be notarized?

No. None of the four statutory forms require notarization.
