Conditional vs unconditional lien waivers: what GCs need to know

Two paragraphs in your construction lawyer's voice:

A conditional lien waiver releases the sub's lien rights only after the payment clears. An unconditional lien waiver releases them the moment the sub signs.

If you mix them up, one of two things happens. Either you pay a sub who's already lost their lien rights for an upstream check that bounced. Or your sub signs unconditional, doesn't get paid, and lawyers up.

This post covers the four types, when each one fits, and the one mistake that costs GCs money every quarter.

The four types in one table

Type	When to use	What it releases
Conditional progress	You're sending payment for work through a specific date	Lien rights through that date, only after the payment clears
Unconditional progress	The payment for that period already cleared	Lien rights through that date, immediately
Conditional final	You're sending the last payment of the job	Lien rights for the entire job, only after the final payment clears
Unconditional final	The final payment cleared	Lien rights for the entire job, immediately

The pattern: conditional is for "we're about to pay", unconditional is for "we already paid".

Conditional progress: the default for every pay period

Use this when you're cutting a check today for work invoiced through a date.

The waiver text says, in effect: "I, the sub, give up my lien rights for this work and this period, but only if the payment actually arrives." If the payment fails, so does the waiver. The sub keeps their lien rights.

This is the form you send first, on every single pay period. It's the one that protects both sides.

When LienDone sends one, the form pulls the state-specific language automatically. California uses one set of words, Texas another, Florida another. The amount, the through-date, the project, and the parties are all pre-filled.

Unconditional progress: only after the check clears

Use this only when the money has moved.

The unconditional version drops the safety net. The sub gives up lien rights immediately, regardless of what happens upstream.

This is where GCs get tripped up. A common pattern: sub signs unconditional, check bounces three days later, sub has no recourse on a lien. The lien rights are gone the moment they signed.

Most U.S. lien statutes write specific protective language into the unconditional form precisely because of this trap. California Civil Code §8134 (unconditional progress) opens with a warning to the claimant in bold: do not sign this until you've been paid. Texas's equivalent says the same.

If your workflow asks subs to sign unconditional in advance, you're working against your own subs and the statute is going to side with them.

Conditional final: the closeout

Last payment of the job. The conditional version releases all lien rights for the entire project, on the condition the payment clears.

Send this with the final pay app. Once the sub signs and the check clears, you're done with that sub on that project.

Most state statutes treat the conditional final as the safer of the two final forms. Use it.

Unconditional final: the kiss of death (if used wrong)

The unconditional final releases all lien rights for the entire job the moment the sub signs.

There's only one time to use it: after the final payment has cleared the sub's account. Confirm the funds, then send the form, then file the signed PDF as the closeout document.

If you're using unconditional final as a precondition for cutting the final check, stop. You're asking the sub to give up their last legal lever before they've been paid. Most subs who've been burned before will refuse. The ones who don't refuse are the ones you're going to burn.

Twelve states have statutory forms you have to use

For most U.S. states, a clean lien waiver in plain English with the right elements (claimant, project, amount, through-date, signature) is legally sufficient.

But in twelve states, the statute prescribes the exact form. California, Texas, Florida, Nevada, Arizona, Georgia, Mississippi, Missouri, Wyoming, Utah, Massachusetts, and Michigan. In those states, a generic waiver form is not enforceable. The sub can sign it, take the check, and still file a lien.

The fix: pick the state in the form picker. The right statutory language fills in. For California specifically, California lien waiver requirements covers the four Civil Code sections and what each one needs. For Texas, Texas lien waiver requirements walks through the Property Code Chapter 53 forms.

The decision in one sentence

If the money hasn't cleared, send conditional. If it has, send unconditional.

That's it. The four-way matrix above is just progress vs final on top of that simple rule.

Common GC mistakes

• Sending unconditional with the check. The sub doesn't have the money yet. They sign, then waitlist your check behind their other receivables. By the time the check clears, you've already given up the only lever they had.
• Using a single PDF template for every state. Works in 38 states. Fails in the other 12, and those 12 include the largest construction markets in the U.S.
• Skipping the through-date. A progress waiver without a through-date releases lien rights for an indefinite period of work. Some courts will narrow that. Many won't.
• Letting subs sign on stale links. A waiver signed six weeks after the pay period ends doesn't reference the right scope. Generate a fresh request, not a re-sent old one.

If you want to skip the entire decision tree, send a waiver in two minutes walks through the four-step flow.

FAQ

Which waiver should I send first?

Conditional. The lien rights only release when the payment clears. If your check bounces or the sub never gets paid, the conditional has no effect and your sub keeps their lien rights.

When do I send unconditional?

After the payment has cleared. Confirm the funds are in the sub's account, then send the matching unconditional waiver to close out that pay period or the job.

Can I use a generic form across all 50 states?

Sometimes. Twelve states require specific statutory language. Use the right form for the state.

What's the difference between progress and final?

Progress waivers release lien rights through a specific through-date for work already invoiced. Final waivers release lien rights for the entire job.

Can a sub refuse to sign unconditional before payment?

Yes, and they should. Signing unconditional before payment is the single biggest legal exposure on the sub side.
