What Is a Lien Waiver? The Four Types, Explained
A lien waiver is a signed document in which a contractor, subcontractor or supplier gives up its right to file a mechanics lien on a property, in whole or in part, usually in exchange for a payment. It works as a receipt the owner, the general contractor and the lender can rely on: this money was paid, so this much lien risk is gone. There are four types, made from two choices: conditional or unconditional, and progress payment or final payment.
What a lien waiver does on a job
A mechanics lien is the trade’s safety net. If you put labor or materials into a property and are not paid, state law lets you claim a lien against that property, and the owner cannot sell or refinance it cleanly until the lien is resolved. Our explainer on how a mechanics lien works covers the notices and deadlines.
The owner’s problem is that the lien can attach even when the owner already paid the general contractor and the GC never paid you. So owners and their lenders ask the GC for waivers from every sub and supplier with each draw, and the GC asks you. Your waiver is how the owner proves the money reached the people who did the work.
A waiver can reach further than the lien itself. The Texas statutory form, for example, releases “any mechanic’s lien right, any right arising from a payment bond,” common law bond rights and “any claim for payment” to the extent the form describes. On a bonded public job, that means the same paper can give up your bond claim too.
The four types, side by side
| Type | When you sign it | What you give up | When it takes effect |
|---|---|---|---|
| Conditional, progress payment | With a pay application, before the check arrives | Lien rights for the work covered by that payment, up to a stated date | Only when the stated payment is actually received and clears |
| Unconditional, progress payment | After the progress payment has cleared your bank | The same rights, with no condition | The moment you sign |
| Conditional, final payment | With your final invoice, including retainage | All lien rights on the job | Only when the final payment is received and clears |
| Unconditional, final payment | After the final payment has cleared | All lien rights on the job, with no condition | The moment you sign |
The rule of thumb that keeps a sub safe: sign conditional forms to get paid, and sign unconditional forms only to prove you already were. Arizona prints that warning on the form itself. Its unconditional waivers must carry the notice that the document “is enforceable against you if you sign it, even if you have not been paid,” under A.R.S. § 33-1008.
Who signs what, and when: one subcontract worked through
Take a plumbing sub on a $48,000 rough-in and trim subcontract under a GC. The contract holds 10% retainage until the end of the job, and the sub bills monthly.
- March 31. The sub bills $14,000 for underground and rough-in. With 10% held, $12,600 is due. The sub sends a conditional progress waiver for $12,600, covering work through March 31, with retainage listed as an exception.
- April 23. The check arrives on the 20th and clears on the 23rd. Only now does the conditional waiver take effect.
- April 30. The sub bills $20,000 for top-out; $18,000 is due after retainage. The GC’s package asks for two forms: an unconditional progress waiver for the March payment of $12,600 that already cleared, and a conditional progress waiver for the new $18,000.
- May 31. Trim-out is billed at $14,000, so $12,600 is due. Same pattern: unconditional for April’s $18,000 once it clears, conditional for May’s $12,600.
- Final invoice. Retainage released: $1,400 + $2,000 + $1,400 = $4,800. The sub signs an unconditional progress waiver for May’s payment and a conditional final waiver for $4,800.
- Final check clears. Now, and not before, the sub signs the unconditional final waiver. Payments add up to $12,600 + $18,000 + $12,600 + $4,800 = $48,000.
At every step the sub has only waived money it already holds, plus money it is about to receive under a waiver that does nothing until the bank pays. If the GC needs these forms collected from your own crew of subs, the companion guide on collecting waivers from subcontractors covers the other side of this exchange.
Mistakes that cost subs real money
- Signing unconditional before the check clears. If the check bounces, you have given up your lien for nothing. Texas makes it illegal to demand this: under Property Code § 53.283 nobody may require an unconditional waiver for a payment unless you actually received it in good funds.
- A through-date past what the payment covers. A waiver “through May 31” attached to a payment for April’s work waives May’s work too. Match the date to the pay application.
- A blank or open amount. “All sums due” or a blank amount line can waive more than the check. Write the exact figure.
- No exceptions listed. Retainage, pending change orders and disputed extras should be written in as exceptions. The Texas progress form does this with the words “except for unpaid retention, pending modifications and changes, or other items furnished.” If the GC’s form has no such line, add one.
- Trusting a custom form. In Texas and Arizona, a waiver that does not substantially follow the statutory form is unenforceable. Florida works differently: § 713.20(8) says a waiver that is not similar to the statutory forms “is enforceable in accordance with the terms” written in it, so read every word of a GC’s homemade form there.
- Forgetting the payment warranty. The Texas forms include a promise that you have paid, or will use the money to pay, your own laborers and suppliers. Sign it only if your supply house bill for that job is current or will be.
States that dictate the wording
Some states write the waiver text into the statute and make other wording useless or risky. Three examples, each worth reading in full before you sign a form there:
| State | Statute | What it says |
|---|---|---|
| Texas | Property Code §§ 53.281 to 53.287 | Four forms. A waiver is unenforceable unless it substantially complies with one of them and is signed; a conditional one also needs evidence of payment. A waiver of lien rights in advance is void, except one written into a contract for a single-family house, townhouse or duplex before work starts (not for material-only suppliers). |
| Arizona | A.R.S. § 33-1008 | Four forms. Conditional forms take effect only when the check “has been properly endorsed and has been paid by the bank on which it is drawn.” |
| Florida | Fla. Stat. § 713.20 | Two forms, progress and final. Lien rights “may not be waived in advance,” nobody may require a different form, and you may condition a waiver on payment of the check. |
Elsewhere, the wording is whatever the contract and the form say, which makes the habits above even more important. For blank versions of all four types, see the lien waiver form templates. This is general information, not legal advice. For a specific job or a form that worries you, ask a construction lawyer licensed in the state where the property is.
FAQ
Does a waiver need to be notarized?
It depends on the state and on who is asking. The Texas statutory forms end with a date, company name, signature and title, with no notary block. Some lenders, title companies and GCs still ask for notarized copies, so check the contract and your state’s statute.
What is the difference between a lien waiver and a lien release?
A waiver gives up the right to file a lien, usually before any lien exists. A release removes a lien that has already been recorded against the property. Texas even treats them separately: its waiver forms do not govern an agreement signed after the lien affidavit has been filed.
Can a GC make me sign an unconditional waiver before paying me?
In Texas, no: Property Code § 53.283 bars requiring an unconditional waiver for money you have not received in good funds. Elsewhere the GC can ask, but you can offer a conditional waiver instead, which protects the GC just as well once the payment clears.
What happens if the check bounces after I sign a conditional waiver?
The waiver never takes effect, so your lien rights for that payment stay intact. Arizona and Texas tie conditional forms to the check being paid by the bank. Keep the returned-check notice, and watch your state’s lien deadlines, which keep running.
Does signing a waiver give up my right to be paid?
It can, for the amount and period the form covers. The Texas forms release “any claim for payment,” not only lien rights, to the extent stated. That is why the amount, the through-date and the exceptions line matter more than anything else on the page.
