Invoicing & Payment

Lien waivers, in plain English

By DoneQuote Editorial · August 24, 2026 · 6 min read

A lien waiver can release rights to secure payment against a property. The form, covered work, payment condition and exceptions determine what you give up under the project state’s law. Check those details against your billing and bank records before signing, especially an unconditional release.

What rights can a lien waiver release?

A mechanic's lien is the security behind your invoice. Filed correctly and on time, it attaches to the property itself, which turns you from someone who is owed money into someone with a claim on the building. That is why the owner and the construction lender care about it far more than they care about your invoice.

A lien waiver may release lien rights over a defined slice of the work. Its effect depends on its wording and state law, which is why a promise of payment is not the same thing as cleared funds.

An owner, lender or GC may require waivers as part of a draw package. Ask which forms are required and for which payment. A requirement to supply a waiver is not a reason to sign an inaccurate release.

Four common waiver forms and their payment conditions

FormReleases your rights whenNormally sent
Conditional waiver, progress paymentThe referenced payment is actually receivedWith each payment application
Unconditional waiver, progress paymentMay take effect when signed and deliveredAfter that draw's funds have cleared
Conditional waiver, final paymentFinal payment is actually receivedWith the final pay application or closeout package
Unconditional waiver, final paymentMay take effect when signed and deliveredAfter final payment, retainage included, has cleared

This table describes common forms; the project state’s law and the actual release control. California’s CSLB provides four statutory forms. A final release can cover more than a progress release, but exceptions differ. Do not sign a final unconditional release while money remains unpaid without legal review.

Conditional means the money has to land

A conditional waiver is generally drafted to take effect only when the named payment is received. If the check never arrives or clears, confirm the form and state rule before assuming your rights survive. An unconditional waiver can take effect on signature, which is why you should not sign it on a promise of payment.

So "actually received" deserves a stricter reading than it gets. A deposited check is not a cleared check. The sequence that protects you on a progress draw is short:

  1. Send the conditional waiver with the payment application, for the amount you are asking for.
  2. Wait for the funds to clear your account, not just appear in it.
  3. Then send the unconditional waiver for that same draw.

Well-run draw packages already work this way: unconditional waivers for the payment previously received, conditional waivers for the payment being requested now. If a GC insists on unconditional up front, offering that split is the reasonable counter — and a conversation to have before the subcontract is signed rather than at 4:40 on a Friday.

The amount field and the through date

Example: a drywall sub has an $86,000 subcontract and is preparing a third draw. The figures below are fictional:

LineAmount
Subcontract value$86,000
Billed through prior draws$41,000
This application, work through August 31$22,400
Retainage withheld on this draw (10%)$2,240
Net payment expected$20,160
Retainage withheld to date$6,340
Approved change order, not yet billed$3,850

If the form asks for the current net payment, the example figure is $20,160. Read each field’s instruction; a waiver may describe the released work by date as well as by payment amount.

For this example, the billed-through date is August 31. Do not substitute a September 9 signature date: depending on the form, that could release later work. Verify any prefilled date against the application.

Check how the form preserves the $6,340 retainage and $3,850 unbilled change. The California conditional progress form expressly excepts retention and unpaid extras. Other forms may need specific entries. Do not force an amount into an unrelated box; get advice if open items are not clearly preserved.

The waivers you collect from everyone below you

Payment to you does not itself prove that your subs and suppliers have been paid. Reconcile their payments and appropriate releases with each draw. Follow the project state’s waiver and prompt-payment rules when setting lower-tier requirements; do not demand an unconditional acknowledgment of money they have not received.

Where your state overrides the form in front of you

Some states prescribe statutory waiver forms. There, a waiver that does not follow the required form may be unenforceable. Never retype a form written for another state; obtain the current form and instructions for the project state.

Before signing, ask whether the project state permits that release before payment and whether it requires a later notice or other follow-up. Do not assume a no-lien clause or a form from another state settles those questions.

None of this touches your lien deadlines. Preliminary notice and filing deadlines run on their own clock, counted in days from a triggering event that differs by state and by tier. Signing or withholding a waiver does not pause them.

Reconcile the waiver with billing and payment records

Compare the waiver with your payment application, billed-through dates, retainage ledger and bank record. DoneQuote holds supporting quote scope and recorded approvals; it does not establish billed-through dates or cleared payments. Record proposed extras with their description, price and schedule impact, and obtain approval before doing them.

Before signing, check payment, dates and exceptions

Before any waiver leaves your office: has the money for this draw cleared, or is it still a promise? Use the project state’s permitted conditional process for an unpaid draw. And does the through date match the last day of work you billed, with retainage and open change orders written into the exceptions?

Then the phone call. Lien law is one of the few areas where the general shape of the rule is not enough — the required form, the notice steps and the deadlines are state-specific, and an error can forfeit lien rights. Read your state's mechanic's lien statute, or spend an hour with a construction attorney licensed where the project sits. Compare the cost of review with the rights and amount at stake.
