Unconditional Waiver and Release on Final Payment (California)

What this form does in one paragraph

California sets out four statutory lien waiver forms, and this is the strongest of them. The Contractors State License Board (CSLB) explains that no lien release is binding unless the claimant signs and delivers a waiver and release, and that a signed form is effective to release the owner, the construction lender and, where there is a payment bond, the surety (CSLB: Conditional and Unconditional Waiver and Release Forms). The unconditional final version releases everything the claimant could still assert on the job, with one narrow exception for disputed extras.

The form's heading notice says it plainly. In capital letters it tells the claimant that the document waives and releases lien, stop payment notice and payment bond rights unconditionally, that it states the claimant has been paid for giving up those rights, and that it is enforceable against the claimant if signed, even if the claimant has not been paid (CSLB form PDF).

For an accounts payable team, that is the reason the form exists: it is the final document that closes out a subcontractor or supplier on a project. For the contractor or supplier signing it, it is the point of no return. Our broader comparison of the two waiver types is in conditional vs unconditional lien waiver.

The four California forms and where this one fits

The CSLB says that, to be effective, waiver and release forms must substantially follow one of the forms in Civil Code sections 8132, 8134, 8136 and 8138 (CSLB). The final unconditional form is the one in section 8138 (California Civil Code 8138). The four forms differ on two questions: is the payment a progress payment or the final payment, and has the claimant actually been paid yet?

The final unconditional form is the only one of the four that releases rights for the whole job with no "through date" and no payment amount on its face. That is what makes it final.

Walking through the 8138 form line by line

The CSLB publishes the form as a one-page PDF, dated 7/1/12 in its footer (CSLB form PDF). It has four blocks.

Notice to claimant. The capitalized warning at the top. It is part of the statutory wording, so a version that drops or softens it no longer follows the form.

Identifying information. Four fields: Name of Claimant, Name of Customer, Job Location and Owner. The claimant is the party giving up rights, usually a subcontractor, supplier or equipment rental company. The customer is the party the claimant contracted with, which is often a general contractor rather than the owner. Use the same names and job address as the contract and invoices so nobody can argue later that the waiver covers a different job.

Unconditional waiver and release. The operative paragraph waives and releases lien, stop payment notice and payment bond rights the claimant has for all labor and service provided, and equipment and material delivered, to the customer on this job. It adds that rights based on work under a written change order fully executed by the parties before the date the claimant signs are also waived and released, unless listed as an exception. It closes with the sentence "The claimant has been paid in full."

Exceptions. The final form lists a single exception: disputed claims for extras, with a blank for the dollar amount. This is the only place on the page where the claimant can preserve anything.

Signature. Claimant's signature, title and date of signature. The date matters, because the change order language turns on which change orders were fully executed before that date.

How the final form differs from the progress version

Comparing the two unconditional forms shows what "final" gives up. The progress version, under section 8134, covers work only through a stated Through Date and records the amount of the progress payment received (CSLB: Unconditional Waiver and Release on Progress Payment, PDF). Its exceptions list three items: retentions; extras for which the claimant has not received payment; and contract rights, including a right based on rescission, abandonment or breach of contract, and the right to recover compensation for work not compensated by the payment.

The final version drops all three of those exceptions. There is no through date, so it covers all work on the job. Retention is not carved out. Unpaid extras survive only if they are disputed claims written into the exceptions line with an amount. If a claimant still expects retention or an approved but unpaid change order, signing the final unconditional form in its standard wording works against that expectation.

For AP teams this suggests a simple sequencing rule. Collect 8134 progress waivers through the life of the job, release retention as part of the final payment, and request the 8138 form only after that final amount has been paid.

Conditional first, unconditional after the money clears

The CSLB's guidance is built around timing. It says to use the conditional final form when the claimant is required to sign a waiver in exchange for, or to induce, a final payment and has not yet been paid. That conditional release is only binding if there is evidence of payment, which the CSLB says may be shown by the claimant's endorsement on a single check or a joint check that has been paid by the bank on which it was drawn, or by the claimant's written acknowledgment of payment (CSLB).

The unconditional final form is for the moment the claimant asserts in the waiver that the final payment was received. The form's own notice tells claimants who have not been paid to use a conditional form instead (CSLB form PDF).

A common sequence on a California job therefore looks like this. The paying party asks for an 8136 conditional final waiver with the final check. The claimant deposits the check and waits until it is paid by the bank. Once the funds are available, the claimant signs the 8138 unconditional final waiver and sends it back. The paying party now holds a release that does not depend on proof of payment.

Paying parties sometimes ask for the unconditional form up front, before releasing the check. The form's warning exists for that situation: if a claimant signs it and the payment never arrives or later fails, the document can still be enforced against the claimant.

What owners and AP teams should check before accepting one

From the payer's side, the CSLB adds a warning worth repeating: paying your contractor, or getting a release from your contractor, does not guarantee that other claimants such as subcontractors and suppliers are paid (CSLB). An 8138 waiver from the general contractor releases only that claimant's rights. Each subcontractor and supplier who could record a lien gives up its own rights only with its own signed waiver.

Practical checks when an unconditional final waiver arrives:

1. The claimant, customer, job location and owner match the contract and the project record.

2. The wording follows the statutory form, notice included, rather than a custom release written by one side.

3. The exceptions line is either blank or shows a specific disputed amount you can track.

4. The signature date falls after the final payment cleared, which you can match against your payment record.

5. You have the corresponding waivers from lower-tier claimants who could still claim rights on the job.

Software that ties each lien waiver to the payment it releases makes the fourth check much faster, because the cleared date of the payment sits next to the signature date of the waiver.

Mistakes that cost claimants money

Most problems with this form come from signing it at the wrong moment or with the wrong blanks left empty. Each of the following follows directly from the form's wording.

Signing when the check arrives instead of when it clears. The form states that the claimant has been paid in full, and its notice says it is enforceable even if the claimant has not been paid. Under that wording, a check that later bounces does not undo the signature. The conditional final form exists for exactly that gap.

Leaving the exceptions line blank while a dispute is open. If you and the customer still disagree about extra work, the only way to keep that claim on this form is to write the disputed amount on the exceptions line. A blank line excepts nothing.

Forgetting about signed change orders. Work under a written change order that was fully executed before you sign is released along with everything else unless you list it as an exception. If a signed change order has not been paid, it should be paid before you sign the final form.

Using the final form for a progress draw. Because it has no through date, signing it for an interim payment releases rights for the whole job, including work you have not yet billed. Progress payments belong on the 8132 or 8134 forms.

Accepting a custom release in place of the statutory one. The CSLB says waiver forms must substantially follow the statutory forms to be effective, so a heavily rewritten document creates uncertainty for both sides.

FAQ

What does this final release form do?
It is California's mandatory final release wording under Civil Code 8138. Signing it gives up your lien, bond and stop-notice claims on the whole project and confirms full payment.

When should I sign it?
Wait until your bank confirms the last check is good. Until then, the notice printed on the form says anyone still waiting on money needs the conditional version of the form.

Is it still enforceable if I was not paid?
Yes. The warning printed at the top says a signed copy binds you whether or not the money arrived.

Does it release retention?
No retention carve-out appears on the final form. The only exception it offers is a line for contested extra-work claims and their dollar amount.

Where do I get the official form?
California's CSLB posts free PDF copies of all four statutory release forms on its website.
