Can a subcontractor refuse to sign an unconditional waiver?

Yes, and if payment hasn't cleared yet, they should. Most state statutes are written specifically to protect subs from signing unconditional before they've been paid; several print a bold warning directly on the statutory form.

Can I use one generic lien waiver form in every state?

No, not in every state. Roughly a dozen states, including California, Texas, Florida, Nevada, Arizona, and Georgia, require the exact statutory wording for each of the four waiver types. A generic form can be unenforceable there even if it was signed willingly.

Does a final waiver cover retainage too?

Generally yes: a final waiver, conditional or unconditional, is meant to release lien rights on the full contract, retainage included, once that money is actually paid. Confirm retainage has been released before signing an unconditional final; otherwise you're waiving rights on funds you haven't received.

Who signs a lien waiver, the sub or the GC?

The subcontractor or supplier signs, because they're the one giving up lien rights. The GC (or, on a final payment to the GC, the owner) is the party collecting the signed waiver in exchange for releasing payment.

Conditional vs. unconditional lien waivers

A conditional lien waiver releases a subcontractor's lien rights only after the payment clears; an unconditional lien waiver releases them the instant the subcontractor signs. Each comes in two versions, progress and final, so there are four total waiver types used in U.S. construction payment. Send conditional when you're paying; send unconditional after the check has cleared.

What's the difference between a conditional and unconditional lien waiver?

A conditional waiver has a built-in safety net: the lien rights only go away once the payment actually lands. If the check bounces or the payment never arrives, the waiver has no effect and the subcontractor keeps their lien rights.

An unconditional waiver has no safety net. The lien rights are gone the moment the subcontractor signs, regardless of what happens to the payment afterward. That's the entire difference, and it's also where the risk sits: send the wrong one at the wrong time and someone gives up a legal right they haven't been paid for yet.

What are the four types of lien waivers?

Conditional and unconditional each split further into progress and final, which gives four total combinations: conditional progress, unconditional progress, conditional final, and unconditional final. Progress waivers cover work billed through a specific date. Final waivers close out the entire contract.

The table below is the reference chart: what each type is used for, exactly what it releases, and the risk if you reach for it at the wrong moment in the payment cycle.

When should you use a conditional waiver instead of an unconditional one?

As the default, every time. Conditional is the form you send with the payment, before it clears. It protects both sides: the GC gets a signed waiver to file, and the sub isn't giving up anything until the money is actually in their account.

Unconditional only belongs in the workflow after the fact, once you've confirmed the payment cleared. Using it as a condition of releasing payment, rather than a confirmation after payment, inverts the whole protection the form is built to provide.

Do all states require the same waiver form?

No. In most states, a lien waiver just needs the right elements (claimant, project, amount, through-date, signature) to hold up. But roughly a dozen states, including California, Texas, Florida, Nevada, Arizona, and Georgia, prescribe exact statutory language for each of the four types. A generic waiver signed in one of those states can be unenforceable even if the sub took the check and signed willingly.

What happens if you sign the wrong one?

If a sub signs unconditional before payment clears and the check bounces, they've lost their lien rights on money they never received. Their only path left is a breach-of-contract claim, which is slower and weaker than a lien. If a GC accepts a conditional waiver but treats it as final proof of release before the payment actually clears, they can end up exposed to a lien anyway once the sub confirms the check never landed.

The four waiver types, side by side

Same structure GCs use to train new AP staff: what to send, what it does, and what breaks if the timing is wrong.

Type	When it's used	What it releases	Risk if used at the wrong time
Conditional progress	Sent with payment for work through a specific date, before the check clears	Lien rights through that date, but only once the payment clears	Low. This is the safe default for every pay cycle.
Unconditional progress	Sent only after that period's payment has already cleared	Lien rights through that date, immediately on signing	High if sent early. Signed before the payment clears, the sub gives up lien rights on money that hasn't landed.
Conditional final	Sent with the last payment of the job	Lien rights for the entire project, once the final payment clears	Low. The standard closeout form once the last check is on its way.
Unconditional final	Sent only after the final payment has actually cleared	Lien rights for the entire project, immediately on signing	Highest. Used as a precondition for the final check, it strips the sub's last legal lever before they've been paid.

Conditional vs. unconditional FAQ

They're closely related and often used interchangeably. A waiver is typically signed before any lien is filed, to prevent one. A release more narrowly refers to the document that removes a lien that's already been recorded. In everyday GC and sub conversation, the two terms mostly overlap.
