About California lien waivers
California requires strict, state-prescribed forms for conditional and unconditional waivers on both progress and final payments. Using a non-compliant form can render your waiver invalid. California is one of the most heavily regulated states for lien waivers in the country.
Key California lien waiver requirements
- Must use the exact statutory form language prescribed in Civil Code §§8132 through 8138
- Four waiver types: conditional/unconditional × progress/final (same structure as Texas)
- Waivers must be delivered in exchange for payment and are not effective until payment is received (for conditional waivers)
- Preliminary 20-day notice rules interact with waiver validity
- Cannot waive lien rights in advance of providing labor or materials
Reference: California Civil Code §§8132, 8134, 8136, 8138
