What Is a Lien Waiver?
By BRIX Editorial Team · Updated
A lien waiver is a signed document in which a contractor, subcontractor or supplier gives up some or all of its mechanic's lien rights, usually in exchange for a payment. Conditional waivers take effect only once the payment actually clears; unconditional waivers take effect when signed. Several states require their own statutory waiver forms.
Key takeaways
- There are four common types: conditional progress, unconditional progress, conditional final and unconditional final.
- Sign a conditional waiver to get paid. Sign an unconditional waiver only after the money is in your account.
- California, Texas, Arizona, Nevada and Utah make non-statutory waivers largely unenforceable; Florida sets forms that others can't make you deviate from.
- Progress waivers usually cover work through a date and exclude retainage, extras and later work.
- Most states don't let an owner or GC make you waive lien rights in advance through the contract.
How does a lien waiver work?
A lien waiver works as a receipt with legal teeth. When an owner or general contractor pays, they want proof that the person they paid, and everyone below them, can't later file a mechanic's lien for that same money. The waiver trades your lien rights for a specific amount through a specific date.
On a typical job with progress billing, waivers move up the chain with every pay application: suppliers and subs sign waivers to the GC, the GC collects them and hands them to the owner or lender along with its own, and the lender releases the draw. Missing waivers are one of the most common reasons a draw gets held up.
What are the four types of lien waivers?
| Waiver | When you sign it | What it gives up | Risk to you |
|---|---|---|---|
| Conditional progress | With a progress invoice, before you're paid | Lien rights for work through a stated date, but only once the stated payment clears | Low, if the amount and date are right |
| Unconditional progress | After a progress payment has cleared | Lien rights for work through the stated date, whether or not you were actually paid | High if signed before the money arrives |
| Conditional final | With your final invoice, before final payment | All remaining lien rights, once final payment clears | Low, if extras and retainage are included in the amount |
| Unconditional final | After final payment, including retainage, has cleared | All lien rights on the job | Highest; there's nothing left to claim |
California's licensing board puts the sequence plainly for homeowners: before paying, get a signed conditional release; after paying, get an unconditional release signed by the actual claimant; and the owner may withhold the next payment until it has the unconditional releases for the previous one.
Conditional vs. unconditional lien waiver: what's the difference?
A conditional waiver only becomes effective when the payment it describes is actually received; an unconditional waiver is effective the moment you sign it. That single difference decides whether a bounced check leaves you with lien rights or without them.
Which states require statutory lien waiver forms?
A handful of states dictate the exact wording of lien waivers. In those states, a waiver that doesn't follow the statutory form generally won't release lien rights, no matter what it says. The table below covers six states with form statutes, checked against the official code on October 12, 2026.
| State | Statute | What the statute requires |
|---|---|---|
| California | Civil Code §§ 8132–8138 | Waivers must follow, substantially, one of four statutory forms: conditional and unconditional, on progress and final payment. A conditional waiver is effective only if the claimant is actually paid. |
| Texas | Property Code §§ 53.281–53.284 | A waiver is unenforceable unless it substantially complies with the statutory form, is signed by the claimant and, for a conditional release, there's evidence of payment. Forms were revised effective January 1, 2022. |
| Arizona | A.R.S. § 33-1008 | A waiver releases lien rights only if it follows substantially one of the statutory forms and is signed by the claimant; conditional releases also need evidence of payment. |
| Nevada | NRS 108.2457 | Contract terms that waive or impair lien rights are void. A waiver is enforceable only in the statutory form and, if conditional, once payment is received. |
| Utah | Utah Code § 38-1a-802 | A written waiver is enforceable only if signed by the claimant and the claimant receives the payment identified in it; the statute supplies the forms. |
| Florida | Fla. Stat. § 713.20 | Lien rights can't be waived in advance. Progress and final waiver forms are set out in the statute, and no one may require a lienor to sign a waiver different from them. A lienor paid by check may condition the waiver on the check clearing. |
What should a lien waiver include?
- Project and owner. The property address and owner name, matching your mechanic's lien paperwork.
- Your customer. The GC or sub who is paying you, if not the owner.
- Amount. The exact payment it covers. For a conditional waiver, the check amount and maker.
- Through date. The last day of work covered. Work after that date isn't waived.
- Exceptions. Unpaid retainage, disputed claims and unbilled change orders should be listed, if the form allows.
- Signature. By you or your authorized agent. Some states and lenders also want it notarized.
Lien waivers by trade
| Trade | Typical setup | Waiver habit to build |
|---|---|---|
| General contractor | Collects waivers from every sub and supplier with each pay app | Don't release payment downstream without a conditional waiver in hand |
| HVAC and plumbing subs | Monthly progress draws on new construction | Conditional with each invoice, unconditional after each payment clears |
| Electrical subs | Progress draws plus change-order work | List unbilled extras as exceptions on progress waivers |
| Roofing | Often one or two payments, sometimes from insurance proceeds | Use a conditional final waiver until the final check clears |
| Suppliers | Sell on open account to contractors | Match each waiver to specific invoices and delivery dates |
Common lien waiver mistakes
- Signing unconditional before you're paid. The single most expensive mistake on this page.
- Signing a final waiver while retainage is still held. Retainage often gets paid months later. Keep a conditional final until it arrives.
- Wrong through date. A through date after your last billed day can waive unbilled work.
- Using a GC's custom form in a statutory-form state. It may be unenforceable, or it may waive more than the statute would.
- Not tracking what you signed. Keep a log of every waiver against the payment it covers.
Lien waivers sit right next to your invoices and payments, so the cleanest setup ties each waiver to the invoice it covers. Our state guides cover licensing and tax rules by state; for waiver forms, go to the statutes cited here.
Frequently asked questions
Is it safe to sign a conditional lien waiver before payment?
Generally yes, as long as the amount and through date are correct. A conditional waiver is designed to take effect only when the stated payment is received, so if the check never clears, your lien rights for that work stay intact. Read the form to confirm it really is conditional.
When should I sign an unconditional lien waiver?
Only after the payment it describes has cleared your bank account. An unconditional waiver is effective when signed, even if the payment later fails. If a GC insists on an unconditional waiver before paying, offer a conditional waiver instead.
Does a lien waiver need to be notarized?
It depends on the state and on who's asking. Some statutory forms don't require notarization, but lenders and title companies often require notarized waivers as a condition of releasing a draw. Check your state's form and the contract.
What is the difference between a lien waiver and a lien release?
A lien waiver gives up the right to file a lien, usually as payments are made. A lien release removes a lien that has already been recorded with the county. If you've recorded a lien and get paid, you'll typically need to record a release.
Does a progress lien waiver cover retainage?
Usually not. Progress waivers typically cover work through a stated date and exclude retainage and work after that date. Make sure your waiver lists retainage as an exception if the form allows it, and don't sign a final waiver until retainage is paid.
Can a contract make me waive my lien rights in advance?
In many states, no. Florida, Arizona and Nevada, for example, make advance waivers in contracts unenforceable or void. Texas allows narrow exceptions for some single-family residential contracts. Check your state's statute before signing a subcontract with a waiver clause.
