Lien waivers: what you are signing, and when to sign it

A lien waiver is a document in which you give up your right to file a mechanics lien, or a claim on a payment bond, in exchange for payment. They are exchanged on nearly every commercial job, usually as a condition of each progress payment, and they are routinely signed by people who have not read them. That is a problem, because the difference between two waiver forms that look nearly identical can be the difference between keeping a claim on the property and giving it away for a check that has not cleared.

This guide explains the four basic types, when each is appropriate, and the habits that keep your rights intact while the money moves.

Why the waiver exists

Owners and lenders need to know that the people who worked on the property have been paid, so that no one files a lien later. General contractors need the same assurance from their subs and suppliers before paying them. The waiver is how that assurance is documented, and it is almost always required before a payment is released.

That creates the timing problem. You are asked to waive rights in exchange for payment, but the waiver is usually requested before the payment arrives. The type of waiver you sign decides who carries the risk in between.

The four types

Waivers are described along two axes: whether they are conditional or unconditional, and whether they cover a progress payment or final payment.

Conditional progress waiver. Waives your rights for work through a stated date, but only once the stated payment is actually received. Until the check clears, your rights are intact. This is the form to use when you are asked for a waiver before payment.

Unconditional progress waiver. Waives your rights for work through a stated date, effective on signing, whether or not you are paid. Sign this only after the payment has cleared your account. Signing it before payment means that if the check bounces or never comes, you have already given up your lien rights for that period.

Conditional final waiver. Waives all remaining rights on the project, including retainage, once final payment is received. Appropriate at closeout, before the final check.

Unconditional final waiver. Waives all remaining rights effective immediately. Appropriate only after final payment, including retainage, has cleared.

Some states have statutory waiver forms, meaning a waiver is only enforceable if it follows the form in the statute. Others allow any form the parties agree on. Where statutory forms exist, a non-conforming waiver may be ineffective or may be read more broadly than you intended. Know which situation your state is in.

What to read before signing

Beyond the type, the words on the page decide what you are giving up.

• The through date. A progress waiver covers work through a specific date. Make sure it matches the period you are being paid for, not a later date that would sweep in unpaid work.
• The amount. Conditional waivers should state the payment they are conditioned on. If the stated amount does not match the check, the waiver may be read as covering more than you were paid for.
• Exceptions. Good waiver forms allow you to list exceptions: disputed amounts, pending change orders, retainage, and claims for extras. If the form has no space for exceptions, ask for one or attach a list. Without it, an unconditional waiver can be argued to release claims you never intended to give up.
• Retainage. A progress waiver should not waive your right to retainage. Check that it says so, or that retainage is listed as an exception.
• Scope of the release. Some forms, especially owner-drafted ones, release not just lien and bond rights but all claims of any kind against the owner and contractor, including contract claims for delay or extra work. That is a general release dressed as a lien waiver. Strike the extra language or refuse the form.
• Who signs. Waivers generally need to be signed by someone with authority to bind the company. Many forms require notarization. A waiver signed by the wrong person may be challenged, which cuts both ways.

Collecting waivers from your own subs and suppliers

Whatever waiver you provide upward, you need the same from everyone below you, because their liens attach to the property regardless of whether you have paid them. Standard practice:

• Require a conditional waiver from each sub and supplier with their pay application, covering the period billed.
• Pay them, then require an unconditional waiver for that period before processing the next one.
• Track waivers by sub, by period, in one place. A missing waiver from a second-tier supplier can hold your own payment.
• Make sure suppliers to your subs are covered too. Many owners require waivers from anyone who has sent a preliminary notice on the job.

Common mistakes

1. Signing an unconditional waiver to get paid faster. The GC's accounts payable asks for it "so we can release the check". The check may still be two weeks away. Sign the conditional form instead; the unconditional one can follow once the money lands.
2. Signing a waiver dated the end of the month for a payment that covers through the fifteenth. The two weeks between are now unpaid and unprotected.
3. Waiving while a change order is pending. List it as an exception every time, or the waiver can be argued to have released it.
4. Missing the preliminary notice deadline earlier in the job. In many states, lien rights depend on a notice served early in the project. If that was never sent, there may be nothing left to waive, and the waiver conversation is moot.
5. Treating the final waiver as paperwork. The unconditional final waiver ends every claim on the job. Reconcile the account, confirm retainage and all change orders are paid, and only then sign.

A simple policy

Write it down and give it to whoever handles billing: conditional waivers go out with pay applications; unconditional waivers go out only after funds have cleared; every waiver states the through date and the amount; exceptions are listed every time; nothing with general release language is signed without a second set of eyes. It is a small routine, and it protects the single strongest collection right a contractor has.

The Float is general information, not legal advice. Lien and bond rights, notice deadlines and waiver forms vary by state and by project type; confirm the rules for each job with your attorney.
