A conditional lien waiver only takes effect once you are paid. Learn conditional vs unconditional, partial vs final waivers, and state rules before you sign.

A conditional lien waiver says: "I give up my lien rights for this amount, but only once the money actually lands." An unconditional lien waiver says: "I give up my lien rights for this amount, period." That one word is the whole difference, and signing the wrong one at the wrong time can cost a contractor the strongest collection tool they have.
I ran three restoration companies for more than 14 years, and I signed a lot of lien waivers. The bad ones all had the same story: someone signed an unconditional waiver because the GC asked for it "to release the check," and then the check showed up short, late or not at all. By then the waiver was already working for the other side.
This guide covers what a lien waiver is, the four types you will see (conditional and unconditional, partial and final), how the rules work in five states that have their own statutory forms, and a simple process for swapping waivers for payments without giving away leverage.
KEY TAKEAWAYS
A lien waiver (also called a lien release or a waiver and release) is a document in which a contractor, subcontractor or supplier gives up some or all of its right to file a mechanics lien against a property, usually in exchange for a payment. Owners, lenders and GCs collect them so nobody files a lien later for a bill that was already paid.
That is a fair ask. On a typical commercial or larger residential job, waivers move with every pay application: the sub sends a waiver with its pay application, the GC sends waivers from its subs along with its own to the owner, and the lender or title company checks the stack before it funds the draw. If you want the bigger picture of how waivers fit into billing, our guide to construction accounts receivable walks through the whole cycle.
The problem is timing. The payer wants the waiver before it pays. You want the money before you waive. Conditional waivers exist to solve exactly that standoff.
Here is the difference in plain terms.
A conditional lien waiver releases your lien rights for a stated amount, on the condition that you actually receive that payment. If the check never arrives, bounces, or comes in short, the waiver does not take effect for the unpaid part and your lien rights stay intact. This is the form you send with a pay app or invoice to get the check cut.
An unconditional lien waiver releases your lien rights for a stated amount, with no condition at all. It is effective the moment you sign and deliver it, whether or not you have been paid. California, Texas and Arizona all put a printed warning on their unconditional forms telling the claimant not to sign unless they have been paid. Take that warning literally.
| Conditional lien waiver | Unconditional lien waiver | |
|---|---|---|
| When it takes effect | Only when payment is received (in most statutory forms, when the check actually clears) | Immediately on signing and delivery |
| If the check bounces | Your lien rights for that amount survive | Your lien rights for that amount are likely gone |
| When to sign it | Before payment, to get paid | After the funds are in your account |
| Who usually asks for it | GCs, owners and lenders with each pay app or draw | GCs, owners and title companies as proof that the last payment was received |
| Risk to you | Low, if the amount and through date are correct | High, if you sign before you are paid |
Tip: A common, sensible pattern on progress billing is: send a conditional waiver for this month's payment, and an unconditional waiver for last month's payment that has already cleared. The payer gets proof that money is flowing, and you never waive money you have not received.
The second half of the picture is how much of the job the waiver covers. Combine the two and you get the four standard types used in most statutory states.
A partial lien waiver, usually called a progress payment waiver, covers one payment for work through a specific date. It leaves your rights intact for work after that date, retainage that has not been released, and any amounts you list as exceptions.
A final lien waiver covers all work on the job. Once a final unconditional waiver is signed, you generally have no lien rights left on that project at all. That includes retainage and disputed change orders. Final waivers should be the last document you sign on a project, after the last dollar clears.
| Type | What it releases | When to sign | Watch out for |
|---|---|---|---|
| Conditional partial (progress) | Rights for a specific payment, through a specific date, once paid | With each pay app or progress invoice | Wrong through date, missing exceptions for disputed or unbilled work |
| Unconditional partial (progress) | Rights for a specific payment through a date, immediately | After that payment clears | Signing it in advance "to release the check" |
| Conditional final | All rights on the job, once the final payment is received | With your final invoice or retainage billing | Open change orders and claims you have not listed |
| Unconditional final | All rights on the job, immediately | Only after the final payment, including retainage, has cleared | This ends your lien rights on the project. There is no taking it back. |
Statutory form or GC form, these fields decide whether it protects you.
CHECKLIST BEFORE YOU SIGN
Watch for language that waives more than lien rights. Some non-statutory forms slip in a release of "all claims" or a statement that you have paid all of your own subs and suppliers. That can turn a simple payment receipt into a broad release of contract claims. If a form says more than "I waive my lien and bond rights for this amount through this date," read it twice and ask your attorney.

Lien waiver law is state law, and it follows the location of the project, not where your office is. Roughly a dozen states publish statutory waiver forms or rules: Arizona, California, Florida, Georgia, Massachusetts, Michigan, Mississippi, Missouri (residential), Nevada, Texas, Utah and Wyoming, according to Levelset's state survey. Rules vary by state. Here is how five of the statutory states handle conditional and unconditional waivers. Always check the current statute, because these laws get amended.
| State | Statute | Forms | What to know |
|---|---|---|---|
| California | Civil Code §§ 8132, 8134, 8136, 8138 | Four forms: conditional progress, unconditional progress, conditional final, unconditional final | A waiver must substantially follow the statutory form. The California Contractors State License Board says a conditional release is binding only with evidence of payment, such as your endorsement on a check the bank has paid. Unconditional forms carry a printed notice warning you not to sign until paid. |
| Texas | Property Code §§ 53.281 to 53.287 (§ 53.284) | Four forms in § 53.284, progress and final, conditional and unconditional | A waiver that does not substantially comply with the statutory form is unenforceable. Under HB 2237, for original contracts signed on or after January 1, 2022, the statutory waivers no longer need to be notarized (Peck Law summary). Older contracts may still follow the earlier rules. |
| Arizona | A.R.S. § 33-1008 | Four forms in subsection D | Waivers must follow substantially the statutory forms. A conditional waiver becomes effective on evidence of payment. Unconditional forms warn that they are enforceable on signing even if you have not been paid. |
| Georgia | O.C.G.A. § 44-14-366 (Morris Manning summary) | Interim and final waiver forms, plus an affidavit of nonpayment | Georgia's forms work differently. Since amendments effective January 1, 2021 (SB 315), a claimant who signs a statutory waiver but is not paid can preserve its rights by filing an affidavit of nonpayment within 90 days after signing the waiver, and waivers are limited to lien and bond rights. Miss that window and the waiver can stand even though you were not paid. |
| Florida | Fla. Stat. § 713.20 | Progress payment and final payment forms | Florida publishes statutory forms, and no one may require you to sign a waiver that is different from them (§ 713.20(6)). The statute also lets you condition a waiver on payment of the check you receive (§ 713.20(7)), which many Florida contractors add to protect against bounced checks. |
This is not legal advice. Lien waiver rules vary by state, depend on project type (public, private, residential, commercial) and change through legislation. The summaries above are general and may not reflect the latest amendments. Read the current statute on your state legislature's site and talk to a construction attorney before you sign a waiver you are unsure about or rely on a deadline.
In most states there is no required lien release form. The payer supplies one, and a court will generally enforce it as written, so an "unconditional" waiver signed before you were paid can hold up. Same habit everywhere: sign conditional until the money clears, list exceptions, keep copies.
This is the routine I would set up in any contractor's office.
| 1 | Know your state's forms before the job starts. Read the waiver section of the subcontract and the project location's statute. Agree on which forms will be used at the kickoff, not when the first check is on the line. |
| 2 | Send a conditional progress waiver with every pay app. Fill in this payment amount, the through date, and exceptions for retainage and any disputed or pending change orders. |
| 3 | Track every payment against its waiver. When a check arrives, compare it to the conditional waiver amount. If it is short, the unpaid part was not waived. Write that down. |
| 4 | Send the unconditional progress waiver only after funds clear. Not when the check is in hand, not when it is deposited. When your bank shows it as cleared. |
| 5 | Bill retainage and open change orders before the final. Get every remaining dollar on a final invoice with a conditional final waiver that lists any exceptions you still have. |
| 6 | Sign the unconditional final last. After the final payment, including retainage, has cleared. Then close the job in your books. |
Two things make this routine fall apart in practice. The first is pressure: the GC says the lender will not fund the draw without unconditional waivers from everyone. The fix is a joint check, a title company that swaps the waiver for the check at the same moment, or a conditional form. It is not signing an unconditional waiver on faith.
The second is follow-up. A conditional waiver protects your lien rights, but it does not collect the money. If the payment is late, you still have to chase it, and you still have to watch your state's lien deadlines while you do. Our guide to the notice of intent to lien and how to file a mechanics lien covers those deadlines. The post on how to collect unpaid construction invoices covers the escalation steps, and the construction invoice collection email templates include wording for pay apps, retainage release and lien notices.
| 1 | Signing an unconditional lien waiver before the money clears. This is the big one. If the check bounces or never comes, you may have waived the right to lien for that money. |
| 2 | Leaving the through date blank or wrong. A blank or late through date can waive work you have not been paid for yet. |
| 3 | Forgetting exceptions. Retainage, disputed change orders and extra work need to be listed, or they may be treated as released. |
| 4 | Accepting a non-statutory form in a statutory state. In states like California, Texas and Arizona, a waiver that does not follow the statutory form may be unenforceable. |
| 5 | Losing the paper trail. If you cannot show which waivers you signed, when, for how much, and which payments arrived, you will have a hard time proving what was and was not released. See our guide to bulletproof documentation. |
Lien waivers are the paperwork side of getting paid. The other side is making sure the payment that waiver was waiting for actually shows up. Most contractors lose time here: the conditional waiver goes out with the pay app and nobody notices the check is late until payroll is short.
AR Workflow's construction accounts receivable software syncs with QuickBooks Online, puts each open invoice on a follow-up schedule, and sends automated payment reminders by email, text and ringless voicemail from a dedicated number. It stops when the invoice is paid and logs every touch. The aging report shows which jobs are slipping past 30, 60 and 90 days, which is often the first sign you need to look at your lien deadlines. For homeowner jobs, reminders can include a payment link so the customer can pay by card or bank transfer from their phone.
None of that replaces the waiver or your attorney. To tighten the front end too, see how to reduce late payments in construction.
A conditional lien waiver gives up your lien rights for a payment only once you actually receive that payment. An unconditional lien waiver gives up those rights as soon as you sign it, whether or not you have been paid. Use conditional waivers to get paid and unconditional waivers to confirm a payment that has already cleared.
In states with statutory conditional forms, such as California, Texas and Arizona, a conditional waiver generally does not take effect until there is evidence of payment, so your lien rights for the unpaid amount remain. Georgia is different: if you are not paid, you may need to file an affidavit of nonpayment within 90 days after signing the waiver to preserve your rights. In states without statutory forms, it depends on the wording. Check your state's statute.
As a rule, no. If a payer insists, ask for a joint check, a simultaneous exchange through a title or escrow company, or a conditional form instead. Once an unconditional waiver is signed and delivered, you may not get those lien rights back.
A partial or progress lien waiver covers one payment for work through a specific date and leaves the rest of your rights in place. A final lien waiver covers the entire job, including retainage. Sign a final unconditional waiver only after the last payment has cleared.
People often use the terms interchangeably, and many statutory forms are titled "waiver and release." Strictly, a waiver gives up the right to file a lien, while a lien release usually refers to removing a lien that has already been recorded. If you have already filed a lien and are being paid, ask your attorney which document your state requires to clear it from the record.
It depends on the state. California's statutory forms do not call for notarization. Texas dropped its notary requirement for statutory waivers on original contracts signed on or after January 1, 2022. Some other states, and some payers' own forms, do require a notary. Rules vary by state, so check your state's statute or ask a construction attorney before you sign.
