Florida Lien Waiver Form: Conditional and Unconditional Templates
Florida law governs lien waivers under Fla. Stat. § 713.20, which establishes four statutory forms — conditional partial, conditional final, unconditional partial, and unconditional final — that subcontractors, suppliers, and contractors use to waive mechanics lien rights in exchange for payment. A conditional waiver only takes effect when the payment clears; an unconditional waiver surrenders lien rights immediately upon signing, regardless of whether the check bounces. Florida does not require you to use the exact statutory language verbatim, but any waiver that substantially conforms to § 713.20 is enforceable and binding. Signing the wrong form at the wrong time — especially an unconditional waiver before funds are confirmed — can permanently strip your right to lien a property and leave you with no legal leverage to collect.
What Is a Florida Lien Waiver and What Does the Law Actually Require?
A Florida lien waiver is a written document in which a contractor, subcontractor, or supplier releases their right to file a mechanics lien in exchange for payment, governed by Fla. Stat. § 713.20. Florida is one of the few states that codifies specific lien waiver forms directly in the statute, which means there is a legally recognized template you can follow — not just informal language drafted by a GC's attorney.
Under § 713.20(2) through (5), Florida recognizes four distinct waiver types:
- Conditional Partial Waiver — Waives lien rights for labor and materials furnished through a specific date, but only becomes effective when the designated payment is actually received and clears.
- Conditional Final Waiver — Waives all lien rights for the entire project, effective only upon receipt and clearance of final payment.
- Unconditional Partial Waiver — Immediately and permanently waives lien rights for work through a specific date, without any condition tied to payment clearing.
- Unconditional Final Waiver — Immediately and permanently waives all lien rights on the project upon signing.
The statute also makes clear that a lien waiver signed by a subcontractor or supplier that deviates from these forms is not automatically void — courts look at whether the document "substantially" conforms to the statutory format. But substantially is a courtroom argument you do not want to be making after a GC has already cashed your labor out and moved on.
What Is the Difference Between Conditional and Unconditional Lien Waivers in Florida?
The difference is timing and risk — a conditional waiver protects you until payment clears, while an unconditional waiver gives up your rights the moment you sign. This is the most important practical distinction in Florida lien waiver law, and getting it wrong is one of the most common ways subcontractors lose their right to collect.
Conditional waivers function like a receipt with a contingency. You're saying: "If I actually receive the money, then my lien rights for this payment period are waived." If the check bounces, the ACH fails, or the GC stops payment, the waiver never becomes effective. Your lien rights remain intact.
Unconditional waivers function like a final sale — no returns. Once signed, the waiver is effective immediately, regardless of what happens to the payment. If a GC hands you an unconditional final waiver at the same time as a check, and that check bounces three days later, you may have already surrendered your right to lien the property.
The rule of thumb used by construction attorneys across Florida is straightforward: always sign conditional waivers until the money is confirmed in your account. Only sign an unconditional waiver after the check has cleared or the wire has settled — never in exchange for a promise of payment.
What Do the Four Florida Lien Waiver Forms Actually Look Like?
Each of the four forms under Fla. Stat. § 713.20 contains specific required elements. Here is what each form must identify:
Required fields on all four forms:
- Name of the claimant (your company)
- Name of the customer (who is paying you)
- Job description / property description
- Specific dollar amount being paid
- Through date (the date through which work is being waived)
- Signature and date
Conditional Partial Waiver — Core Language (§ 713.20(2)): The waiver becomes effective "upon receipt of the sum of $____ payable to ____." It waives lien rights "for labor, services, or materials furnished through [date]" but explicitly preserves rights for work outside that period.
Conditional Final Waiver — Core Language (§ 713.20(3)): Becomes effective upon receipt of final payment. Waives "all liens, lien rights, claims, or demands of any kind" once payment clears. This is a complete release of all rights on the project.
Unconditional Partial Waiver — Core Language (§ 713.20(4)): States the claimant "has been paid and has received" the specified amount. Rights are waived immediately for work through the stated date. No contingency language.
Unconditional Final Waiver — Core Language (§ 713.20(5)): States the claimant "has been paid in full" for all work. Waives all liens and claims on the project. Effective immediately upon signing.
One additional protection under Florida law: § 713.20(1) states that a waiver of lien is unenforceable if it is executed prior to the subcontractor or supplier actually furnishing any labor, services, or materials. GCs sometimes include prospective lien waivers in subcontract agreements — those clauses are void under Florida statute.
When Should You Sign Each Type of Lien Waiver?
Sign the form that matches the payment status — conditional for pending payments, unconditional only after funds have cleared. Here is the practical breakdown by scenario:
| Situation | Correct Form |
|---|---|
| GC is issuing a progress payment by check | Conditional Partial |
| Progress payment by wire, not yet confirmed | Conditional Partial |
| Progress payment confirmed cleared in bank | Unconditional Partial |
| Final payment by check at project closeout | Conditional Final |
| Final payment wire confirmed in account | Unconditional Final |
| GC asks for waiver before any work starts | Refuse — void under § 713.20(1) |
The timing risk is highest on final payment. GCs and owners routinely request an unconditional final waiver at the same time as the final check. Do not sign an unconditional final waiver at the table in exchange for a check you have not deposited and confirmed. Sign a conditional final waiver instead. Once the check clears — typically 2–5 business days — you can then provide the unconditional final if required.
Can a GC Force You to Sign a Non-Statutory Lien Waiver Form in Florida?
A GC can present any form they want, but Florida law limits how much your signature can legally surrender. Under Fla. Stat. § 713.20, a lien waiver that does not substantially conform to the statutory forms may not be enforceable as written — but "may not be enforceable" is a legal fight, not a guarantee.
Watch for these red flags in GC-drafted lien waiver language:
- Broad release language that purports to waive not just lien rights but also claims for breach of contract, change orders, or retainage not yet due
- Waivers tied to future work that attempt to release rights for work not yet performed (void under § 713.20(1))
- Joint check provisions that require you to waive your lien rights before the joint check is actually issued
- Indemnification clauses bundled into waiver forms that expose you to liability beyond the project
If a GC insists on a form that goes beyond § 713.20 language, have it reviewed by a Florida construction attorney before signing. A single phone call is cheaper than litigating a disputed waiver on a six-figure subcontract.
How Do Florida Lien Waivers Connect to the Preliminary Notice Process?
Lien waivers and preliminary notices are two separate tools — the notice protects your right to lien before payment disputes arise, and the waiver releases that right once payment is made. You cannot waive a lien right you never properly preserved.
In Florida, subcontractors and suppliers who do not have a direct contract with the property owner must serve a Notice to Owner (NTO) under Fla. Stat. § 713.06 within 45 days of first furnishing labor or materials. Without a timely NTO, your mechanics lien rights may be limited or eliminated entirely — which also means you have nothing meaningful to waive in exchange for payment leverage.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. Your NTO is the document that keeps you in the payment chain when disputes arise. Your lien waiver is what you exchange once you've actually been paid.

What Are the Most Common Mistakes Florida Subcontractors Make With Lien Waivers?
The three most costly mistakes are signing unconditional waivers before payment clears, signing waivers that release more than lien rights, and failing to track which payments have been waived.
Mistake 1: Signing unconditional waivers in exchange for uncashed checks. This is the most common and most damaging error. A $40,000 check that stops payment after you signed an unconditional final waiver leaves you with no lien rights and a civil lawsuit as your only remaining option.
Mistake 2: Accepting bundled releases in GC-drafted forms. A GC's in-house form might waive lien rights, contract claims, change order disputes, and retainage in a single signature block. You may be releasing claims worth more than the payment you received.
Mistake 3: Losing track of partial waiver through dates. If you sign a conditional partial waiver for work through March 31 and then later sign another for work through April 30 without confirming the March payment cleared, you may be stacking unresolved payment risk across multiple waivers. Maintain a written log of every waiver signed, the through date, the payment amount, and the confirmation date that payment cleared.
Mistake 4: Ignoring retainage. Florida retainage is typically 10% held back throughout the project under Fla. Stat. § 715.12. A partial waiver through a specific date should explicitly carve out retainage not yet due. If a GC's form does not contain that carve-out, add it before signing.
Frequently Asked Questions
Is Florida a statutory lien waiver state?
Yes. Florida is one of a limited number of states that codifies specific lien waiver forms in statute. Fla. Stat. § 713.20 establishes four recognized forms — conditional partial, conditional final, unconditional partial, and unconditional final. Waivers that substantially conform to these forms are enforceable. Florida does not require you to use the forms word-for-word, but deviating significantly creates legal uncertainty.
Can a lien waiver in Florida be signed before work begins?
No. Under Fla. Stat. § 713.20(1), a lien waiver executed before the claimant has furnished any labor, services, or materials is unenforceable. This means pre-construction lien waivers or prospective waivers buried in subcontract agreements cannot legally strip your right to lien before you have done any work.
What happens if I sign an unconditional lien waiver and the check bounces?
You have likely lost your mechanics lien rights for the work covered by that waiver. An unconditional waiver takes effect immediately upon signing — it is not conditioned on payment clearing. Your remaining options would be a breach of contract claim or a claim under Florida's Construction Lien Law for fraudulent inducement, but both require litigation. Always sign conditional waivers until payment is confirmed.
Does signing a lien waiver waive my right to sue for breach of contract?
Not automatically — but it can if the waiver language extends beyond lien rights. The Florida statutory forms under § 713.20 are limited to liens, lien rights, claims, and demands. GC-drafted forms sometimes include broader release language covering contract claims, change orders, or dispute rights. Read every waiver before signing and strike or negotiate any language that goes beyond lien rights if payment is still in dispute.
Do I need a lawyer to sign a Florida lien waiver?
The law does not require an attorney to sign a lien waiver. But for any project where the payment amount is significant, having a Florida construction attorney review the waiver form — especially if it deviates from the § 713.20 templates — is worth the cost. A one-time review of a GC's standard form can protect you on every project you do with that GC.
How does retainage affect lien waivers in Florida?
Florida retainage — typically 10% withheld under Fla. Stat. § 715.12 — should always be carved out of partial lien waivers. Your conditional partial waiver should cover only the payment amount being made, not retainage that has not yet been released. If the GC's form does not clearly exclude retained amounts, add explicit carve-out language before signing: "Excludes retainage of $____ not yet due."
Can a GC require me to use their own lien waiver form instead of the statutory form?
A GC can request that you use their preferred form, but Florida courts evaluate waivers based on whether they substantially conform to § 713.20. A GC cannot contractually force you to sign a waiver that waives rights before work is furnished (void under statute) or that strips you of rights beyond what the law permits. If their form deviates significantly, you have the right to negotiate.
Where do I get a Florida lien waiver form?
The four statutory forms are set out directly in Fla. Stat. § 713.20. You can draft waivers based on that language, use attorney-reviewed templates, or obtain compliant forms from your state contractor association. The most important thing is that the form identifies the correct parties, the correct payment amount, the correct through date, and uses the appropriate conditional or unconditional designation.
Protect Your Lien Rights Before You Waive Them
A lien waiver is only worth something if you had preserved the right to lien in the first place. Before you sign anything, make sure your Notice to Owner was served on time and your lien rights are intact.
LienFlash files Florida Notices to Owner in under 2 minutes — attorney-reviewed forms, sent via USPS Certified Mail, with a Certificate of Mailing PDF delivered to your inbox for $24.99 per notice. Preliminary notices filed on U.S. construction projects covered $22.7 billion in work in 2024 alone (Lienser via DocJoist, 2024). That protection costs less than a lunch.
