Lien Waiver Guide, Forms & Resources
What lien waivers are, the four types — conditional, unconditional, progress, final — and the state-specific waiver rules that decide which form fits.
A lien waiver is the document a contractor, subcontractor, or supplier signs to give up mechanics lien rights in exchange for payment. Waivers move in the opposite direction from liens: a lien claims money owed, a waiver releases the claim after payment.
The form matters as much as the payment. Each waiver type matches a payment state — whether the money is in hand or on the way, and whether the payment is a progress payment or the last one. Several states prescribe the exact form, and using the wrong one can release more rights than the payment covers.
Waivers are exchanged against payment rather than filed with a court or a county office, so the paperwork stays with the two parties. The claimant signs and sends the waiver with the pay application or the invoice; the payer releases the money; both keep a copy for the payment file. What the document does is narrow and specific: it releases lien rights for the work and the amount it names, which is why the payment period and the amount are filled in before anyone signs.
The four waiver types
Conditional vs. unconditional
A conditional waiver is tied to the payment actually clearing — in Florida a lienor may make a waiver conditional on the check clearing (§713.20(7)). An unconditional waiver is effective on signature, regardless of whether the payment has arrived. In Florida, a waiver signed before the work is furnished is unenforceable (§713.20(2)).
Progress vs. final
A progress waiver covers a payment drawn against the contract to date and leaves the remaining balance under lien. A final waiver covers the last payment and closes the lien on the job. California prescribes a separate statutory form for each of the four combinations — conditional progress, unconditional progress, conditional final, unconditional final (§§8132–8138).
Choosing among the four
The choice runs on two questions, in this order. First, has the money arrived? A payment still in transit points to the conditional form; funds that have cleared point to the unconditional one. Second, is this the last payment on the job? A payment against the contract to date is a progress release; the payment that closes the job is a final release. Getting the order wrong is what produces an over-release: an unconditional form signed while the money is still moving gives up rights the payment may never cover, and a final form signed against a progress payment closes a lien the job still needs.
The exchange, step by step
The waiver travels with the payment request, not after it. The claimant fills in the amount, the period, and the property, signs, and sends the document with the application or invoice; the payer releases the money; both sides keep a copy for the payment file. Signing a waiver that names a different amount from the payment being released is the most common mismatch — the document should cover the payment it is exchanged for, no more. On conditional forms nothing is released until the payment clears; on unconditional forms the release is effective at signature, so the payment state has to be settled first.
Retainage and the final waiver
The retained percentage comes back in one or two releases, and each release carries its own waiver — a progress waiver while retainage is still being withheld on later work, a final waiver on the payment that closes the job. The final waiver is the one that ends the lien relationship: once it is signed unconditionally, no lien can be recorded for the work it covers. That is why the amount and the period on the final form have to match the last payment exactly.
Waiver rules by state
Waiver forms live inside each state’s mechanics lien statute. The state pages carry the lien deadlines the waiver exchange runs alongside; the notes below flag the waiver-specific rule we verified for each state.
California
Statutory waiver forms: four prescribed formats, one per payment state (§§8132–8138). A contract term by which another party waives or impairs a claimant’s lien rights is void unless and until the claimant executes a statutory waiver (§8122).

A waiver signed before the work is furnished is unenforceable (§713.20(2)); a lienor may make a waiver conditional on the check clearing (§713.20(7)).

Lien waivers questions, answered straight.
What is a lien waiver?
A signed document in which a contractor, subcontractor, or supplier gives up mechanics lien rights in exchange for payment. Waivers are exchanged at each payment: progress payments with progress waivers, the last payment with a final waiver.
What is the difference between a conditional and an unconditional lien waiver?
A conditional waiver is tied to the payment clearing; an unconditional waiver is effective on signature. In Florida, a waiver signed before the work is furnished is unenforceable (§713.20(2)), and a lienor may make a waiver conditional on the check clearing (§713.20(7)). California prescribes a separate statutory form for each payment state (§§8132–8138).
When is a final waiver used?
With the last payment on the job. California pairs final waivers with statutory forms (§§8132–8138), and Texas has statutory waiver forms (§53.284(b)–(e)). The state page for the job’s state carries the lien deadlines the waiver exchange runs alongside.
Can a waiver be signed before the payment arrives?
Yes, if it is conditional. A conditional waiver releases lien rights only when the payment it names actually clears, and Florida lets a lienor make a waiver conditional on the check clearing (§713.20(7)). An unconditional waiver signed before the money arrives releases the rights at signature, with no condition to fall back on. Florida also makes a waiver signed before the work is furnished unenforceable (§713.20(2)) — a different point in the job from an invoice that is merely unpaid.
What should a progress waiver cover?
The payment it is exchanged for and the period that payment covers — nothing beyond that. A progress waiver leaves the remaining contract balance, retainage included, under lien, so the document is written against a specific application rather than against the job as a whole. If the payer asks for a waiver that names a larger amount or a later period than the payment covers, the mismatch is the thing to fix before signing: the waiver and the check should describe the same payment.
