Can a Subcontractor Still File a Lien After Signing an Unconditional Waiver?

A sub signs an unconditional waiver, gets paid, and moves on. Two months later a dispute starts over a change order. Can they still lien the job?

Short answer: not for what that waiver covers. Yes for what it leaves out. Most of the fights happen in the gap between those two sentences, so this post is about where that gap is.

Short version. An unconditional waiver releases the sub's lien rights for the work, period and amount on the form, the moment it is signed. It does not release work after the through date, items listed as exceptions, or anything on a form that does not meet your state's rules. Not legal advice.

What an unconditional waiver releases

The unconditional waiver is the receipt. The standard wording says the sub has been paid and releases any mechanic's lien, stop payment notice or bond right on the job, to the extent described on the form. There is no condition attached. The release takes effect when the sub signs.

That is why the form exists in two versions. The conditional waiver waits for the payment to clear. The unconditional version does not wait for anything. If the check bounces after the sub signed it, the release still stands. Our guide on signing before payment covers how to avoid that.

Two forms matter here:

• Unconditional progress waiver. Releases the sub's rights for the work covered by one payment, through the date on the form.
• Unconditional final waiver. Releases the sub's rights for the whole job. This is the closeout document.

What it does not release

This is the part that surprises people on both sides of the table.

1. Work after the through date. A progress waiver is scoped by a through date and an amount. Work done after that date is not released. If a sub signs a progress waiver through June 30 and keeps working in July, July is still open.

2. Listed exceptions. The standard forms have an exceptions section. The usual items are contract retentions, disputed claims and extras not yet billed. Whatever is listed there stays open. If the form has no exceptions section and says "all rights through this date", it can sweep in retainage too. We cover that trap in the retainage carveout post.

3. Anything the form does not describe. The release covers the project, the customer and the period named on the form. A waiver for one project does not release rights on a different one.

4. The debt itself. The wording in the standard forms releases lien, stop payment notice and bond rights. It does not say the money is no longer owed. Whether and how a sub can collect without a lien is a question for an attorney in your state, and we are not going to guess at it here.

5. The sub's own suppliers and lower-tier subs. A waiver releases the signer's rights, not anyone else's. A supplier or lower-tier sub that your sub hired generally has rights of its own, and in many states it may be able to lien to the extent it has not been paid, even after your sub signed. This is the surprise for a GC who thinks one signed waiver closes out a whole chain. Ask your subs who they paid, and collect waivers from lower tiers where you can.

Three examples

The names and numbers below are invented to show the mechanics. Your facts, your form and your state decide the real answer.

The July work. A sub signs an unconditional progress waiver through June 30 for $24,000, after the check has cleared. In July the sub does $9,000 more work and is not paid. The waiver does not reach July, because the through date limits it. The June payment is released. The July work is not.

The retainage. A sub signs an unconditional final waiver on the GC's own template, which says "all rights" and has no exceptions section. $6,000 of retainage is still unpaid. A final waiver releases lien rights for the entire job, including retention, unless the sub carves it out in writing. This sub has probably released the retainage along with everything else. A sub who listed it as an exception, or used a state form with a printed retention exception, would not have.

The tile supplier. A sub signs an unconditional final waiver and gets paid, but never pays its tile supplier. The sub's waiver releases the sub's rights. The supplier has rights of its own and, in many states, may be able to lien if it gave any required notice on time. The GC who holds only the sub's waiver is exposed to the supplier's claim.

Conditional versus unconditional: what changes the answer

	Conditional waiver	Unconditional waiver
Takes effect	When the payment clears	When the sub signs
If the payment fails	No effect. The sub keeps lien rights	Still released
When it is signed	With the pay app, before payment	After the funds are available
What it limits	Through date and amount on the form	Through date and amount on the form
Can a lien follow?	For anything not covered, and for everything if the payment never clears	For anything not covered

If you only remember one row: a failed payment cancels a conditional waiver and does nothing to an unconditional one.

When the waiver does not hold up

Signing is not always enough.

The state prescribes the form and the form was not followed. Twelve states publish a form: California, Texas, Florida, Georgia, Arizona, Massachusetts, Michigan, Mississippi, Missouri, Nevada, Utah and Wyoming. In most of them a departure from the form can cost you. In California, a waiver that is not substantially in the statutory form is null, void, and unenforceable, and the notice on the unconditional form has to stay in type at least as large as the largest type on it. In Texas, a waiver that does not substantially follow the four statutory forms is unenforceable unless the sub was paid in full. Utah and Wyoming print forms, but we found no section that says what happens to a waiver in another form. A sub who signed a home-made form in one of these states may not have released anything. Florida is softer. Its statute says the two forms are what a lienor may be asked to sign, and that a different waiver is enforceable in accordance with its own terms, so a home-made Florida waiver can still release what it says it releases.

The waiver was an advance waiver. Several states refuse to enforce a waiver signed in advance of payment. Indiana voids contract clauses that make a sub waive lien rights before payment. Michigan voids advance contractual waivers and treats a waiver as effective only to the extent of payment actually received.

The wording reaches further than the signer expected. Wisconsin goes the other way. Section 779.05 makes a signed waiver binding whether or not any money was paid. It also presumes a waiver covers all of the signer's lien rights on the improvement unless the document expressly limits it. In Wisconsin, a vague unconditional waiver can release far more than one pay period.

If you build in more than one state, the state-by-state requirements page shows which rule applies where.

How the answer changes by state

The core rule is the same everywhere. The details are not. This is what our state guides say for a few states:

State	What changes the answer
California	The notice on the unconditional forms (§8134, §8138) is part of the required text, in type at least as large as the largest type on the form. Remove or shrink it and the waiver breaks substantial conformance
Texas	§53.281 and §53.282 make a waiver that deviates materially from the four §53.284 forms unenforceable unless the claimant was actually paid in full, and until then the sub can take the check and still file a lien. §53.286 voids contract terms that waive future lien rights, except for single-family, townhouse and duplex contracts
Georgia	The interim waiver releases lien rights only for the specific amount listed. A form that omits the required notice is void, and the claimant keeps lien rights as if no waiver had been signed
Michigan	Four statutory forms under MCL §570.1115. A waiver is effective only to the extent of payment actually received, and advance contractual waivers are void
Wisconsin	§779.05(1) makes a waiver binding whether or not it was paid, and presumes it covers all of the signer's lien rights on the improvement unless it says otherwise
Indiana	IC §32-28-3-16 voids contract provisions that make a sub waive lien rights before payment
Illinois	No statutory form. 770 ILCS 60/21.02 treats money collected for a waiver as held in trust for the sub, and waiver scope is read strictly

For the rest, use the state-by-state requirements page.

If you already signed one you should not have

This happens. A sub signs an unconditional waiver on the GC's say-so, and the check never arrives. Or a GC finds a form in the file that looks wrong. In either case:

1. Read it again, slowly. Which form is it, what is the through date, what amount, and are there any exceptions?
2. Check whether the money cleared. Not whether it was promised or deposited, but whether the funds were available.
3. Gather the paper. The contract, the pay apps, the emails about payment, and the signed waiver.
4. Write down the deadline. Lien clocks run from the last day of work. In our state guides: Illinois 4 months to record, Ohio 75 days on commercial work, Indiana 90 days on commercial, Wisconsin 6 months, Minnesota 120 days. The lien deadline calculator works out a date.
5. Talk to a construction attorney before you sign anything else. Do not sign a second waiver to "fix" the first one, and do not tell the other side what you think the first one means, until someone who knows your state has read it.

None of this is a guarantee of any outcome. It is a way to avoid making the situation worse while you find out where you stand.

What a GC should check before relying on one

An unconditional waiver in your file is only as good as what is written on it. Before you count a sub as closed out:

1. The through date matches the last day of work the payment covers.
2. The amount matches the payment that actually cleared, not the contract total.
3. The exceptions are filled in on purpose. If the sub left retainage or a disputed item open, you know about it.
4. The form is the state's own wording if your project is in a statutory state.
5. The chain below the sub. If the sub used suppliers or its own subs, ask whether they are paid and whether you hold their waivers too.
6. The date signed is after the funds cleared. A sub who signs the unconditional version before payment is signing away rights early. That is not a good place to be, and in some states it exposes you too.

A waiver that fails any of these is a reason to ask for a corrected one, not a reason to assume the lien right is gone.

What a sub should check before signing

• Is this the unconditional version? Only sign it after the funds are in your account.
• Do the through date and amount match what you were paid?
• Are retainage, change orders and disputed items listed as exceptions if they are still open?
• Is it your state's form, with the required warning notice, if your state publishes one?
• Do you have a copy? Keep every waiver you sign, in order, so you can prove what you released and when.

Make this easy to get right

A waiver that goes out with the right form, the right amount and the right through date is the whole job. LienDone picks the statutory form for the project's state, fills in the amount and through date, and sends the sub a link they sign on their phone with no account. Subs see the GC's company name first. The signed PDF lands in your dashboard, filed by project and pay period.

Try it on a real job. Start a 14-day free trial. No card. Add one project and one sub, send a waiver, and see what your sub sees.

Not ready? Check a form you already use with the free lien waiver audit, or make a single waiver with the free lien waiver generator. For the form itself, see the unconditional final waiver.
