How to Fill Out a Partial Lien Waiver: Fields, Retainage, and Delivery

To fill out a partial lien waiver, choose a conditional form if payment hasn’t cleared yet, enter the claimant, customer, and owner names exactly as they appear on the contract, identify the property, state the payment amount you’re being paid on this draw, set the through date to the end of that billing cycle, and list any retainage, disputed change orders, or unpaid extras as exceptions so they aren’t swept into the release. Every field on the form controls a specific piece of your lien rights, and small errors, especially in the waiver type, the dollar amount, and the through date, can surrender protection on work you haven’t been paid for.

Choose Conditional or Unconditional Before Anything Else

The single most important decision on the form is which version you’re signing. A conditional partial waiver only takes effect once you actually receive the payment described in it. If the check bounces or the wire never lands, the waiver is void and your lien rights stay intact. Texas puts this in the statutory language itself: the waiver becomes effective only “when the check has been properly endorsed and has been paid by the bank on which it is drawn.”¹ California’s conditional release binds you only when there’s evidence of payment, such as your endorsement on a cleared check.² Michigan’s statute uses the same rule: the partial conditional waiver becomes effective “upon payment of the amount indicated in the waiver.”³

An unconditional partial waiver is effective the moment you sign it, whether or not the money has landed. Once signed, your lien rights for the stated amount are gone. If the payment then falls through, you can’t file a mechanic’s lien; you’d have to pursue a breach-of-contract claim. The Texas statutory form for unconditional progress-payment waivers carries a built-in warning: “It is prohibited for a person to require you to sign this document if you have not been paid the payment amount set forth below.”¹

The practical rule: send a conditional waiver with your pay application, and only sign an unconditional waiver after the funds have cleared your account.

Filling In Each Field

Partial waivers vary by state and by template, but the core fields are the same. Complete them in order and check each one against the underlying invoice or pay application before you sign.

Parties

Enter the full legal names of the claimant (you or your company), the party you contracted with, and the property owner. Use entity names exactly as they appear on the contract. “Smith Brothers Construction LLC,” not “Smith Bros.” Michigan’s statutory form requires both the contracting party and a description of what was provided.³ Add the project name and contract or job number so the waiver ties cleanly to the correct pay application in the project records.

Property Description

Identify the property where the work was performed. A street address works on many forms, but the legal property description (lot, block, and subdivision reference from the county recorder) is safer. In roughly a dozen states, a mechanic’s lien can be thrown out if it lacks a full legal description. New developments often don’t have street addresses assigned yet, so the legal description from the deed or title commitment may be all you have. When in doubt, put both on the form.

Payment Amount

State the exact dollar amount you’re waiving lien rights against. This should match the invoice or pay application for the billing period, not a rounded number and not the total contract value. Double-check the figure against the draw request. A transposed digit can waive thousands of dollars more in rights than you were paid. Michigan’s form asks you to “waive my/our construction lien to the amount of $__” and to indicate whether that waiver, combined with all previous ones, covers everything owed through the stated date.³

The Through Date

This field causes the most expensive mistakes. The through date is the cutoff: you’re waiving lien rights for all labor and materials furnished up to and including that date. If you set the through date a week past your actual billing period, you’ve given away lien protection for a week of unpaid work. Match the through date to the end of the billing cycle the payment covers, not the day you sign and not the day you expect the check.

Exceptions and Exclusions

Most well-drafted waivers include a section, sometimes just a blank line, for work or amounts not covered by the release. California’s statutory forms state that the waiver “does not cover any retentions retained before or after the release date; extras furnished before the release date for which payment has not been received; extras or items furnished after the release date.”⁴ If your form has no preprinted exception language, write in disputed amounts, pending change orders, and unpaid extras. Silence on those items can be read as a release.

Handling Retainage

Most construction contracts hold back 5% to 10% of each progress payment as retainage until substantial completion. That withheld amount should not be included in the waiver amount. If you waive lien rights for the full invoice but only received 90% of it, you’ve surrendered protection on money the owner is still holding. To preserve lien rights on retainage, either use a form that expressly excludes it (California’s statutory templates do) or write a line excluding the retained portion from the waiver.

Check Whether Your State Requires a Specific Form

About a dozen states require the waiver to substantially conform to a statutory template, and a court can invalidate a nonconforming waiver. Those states are Arizona, California, Florida, Georgia, Massachusetts, Michigan, Mississippi, Missouri, Nevada, Texas, Utah, and Wyoming.

Several add specific requirements on top of the template rule:

Georgia requires waivers to be in at least 12-point font and to include a notice warning that the signer will be “conclusively deemed to have waived” lien rights 90 days after the date on the form, even without payment, unless an affidavit of nonpayment is filed inside that window. A form missing the notice language is unenforceable.⁵
California provides four separate statutory forms covering the four waiver types (conditional and unconditional, each for progress and final payment), at Civil Code sections 8132 through 8138.²
Texas has four templates under Property Code section 53.284; a waiver that doesn’t substantially comply is unenforceable.¹
Nevada does not allow lien rights to be waived by a blanket contract term. Only waivers executed in the statutory form and delivered with or after payment are enforceable.⁶
Florida statute 713.20 provides a recommended form and prohibits any party from forcing a claimant to use a different one.⁷
Michigan prescribes four templates. On residential projects, an owner who receives a waiver indirectly (not from the claimant personally) can’t rely on it without contacting the claimant to verify authenticity.³

In states without mandatory forms, any written waiver works as long as it clearly identifies the property, the amount waived, the through date, and the parties. The accuracy rules for each field are the same.

Signatures and Notarization

Most states do not require notarization for a partial lien waiver to be valid. The notable exceptions are Georgia, Mississippi, and Wyoming. Georgia technically requires a witness and seal, and notarization is the standard approach when no corporate seal is available. Mississippi requires notarization on final waivers. Even where the state doesn’t require it, some general contractors and lenders demand notarization by contract, so check your agreement before assuming you can skip it.

The waiver must be signed by the claimant or an authorized agent. If someone else in your company signs on your behalf, make sure they have documented authority. An unauthorized signature can make the waiver unenforceable.

Delivering the Signed Waiver

Delivery method depends on the contract and the project’s payment workflow. Many modern projects use construction management software that timestamps uploaded waivers and routes them to the paying party. Certified mail with return receipt gives you proof of delivery if a dispute later arises about whether the waiver was received. Some contracts accept scanned copies by email or hand-delivered originals at the project office. Whichever method you use, keep a copy for your records. On a conditional waiver, receipt of payment triggers effectiveness; on an unconditional waiver, the release took effect when you signed.

Mistakes That Cost Contractors Money

Signing unconditional before payment clears. If a check comes with an unconditional waiver and the check then bounces, your lien rights for that amount are already gone. Use a conditional waiver until the funds hit your account.
Setting the through date past the billing period. You’ve just waived rights on work you haven’t been paid for. Align the date with the end of the cycle the payment covers.
Including retainage in the waiver amount. Waiving $100,000 when the owner withheld $10,000 releases leverage on money you haven’t received. Make the amount match what you’re actually paid on this draw.
Using a generic form in a state that mandates a template. A court in any of the twelve mandatory-form states can throw out a nonconforming waiver.
Failing to note exceptions. Disputed change orders, unpaid extras, and pending back-charges belong on the exceptions line. Silence can be read as a release.
Signing an advance waiver where state law prohibits it. Michigan and Georgia, among others, void blanket lien-waiver clauses in the original contract.³⁵
