What is Full Unconditional Waiver?
Unconditional Waiver Form (Unconditional Waiver and Release Upon Final Payment) is a statutory legal document used in California to confirm that a lien claimant has received full payment for their contributions to a construction project. This form serves as a formal declaration that the contractor, subcontractor, or material supplier has been compensated in full for all labor, services, equipment, or materials provided to the job site. By signing this document, the claimant unconditionally waives and releases all mechanic's lien, stop payment notice, and bond rights against the property and its owners.
The document captures essential identifying information, including the names of the claimant and customer, the specific job location, and the property owner. It includes a prominent notice warning the signer that the waiver is legally enforceable even if they have not actually received the payment, which distinguishes it from conditional versions. This construction lien waiver is signed by the claimant and serves as final proof that no further claims will be made against the project’s financial security once the final payment is successfully processed.
