Lien waiver

How a lien waiver works

Lien rights come from state law. In general, anyone who improves a property and isn’t paid may be able to record a mechanic’s lien against it, including subs and suppliers who never dealt with the owner. That creates a risk for the owner: they can pay the general contractor in full and still face a lien from a supplier the general contractor didn’t pay.

A lien waiver is how each payment gets matched to a promise not to lien for it. The owner, the lender or the general contractor collects a waiver from whoever they pay, and often from the tiers below them, before or right after releasing money. Paperwork flows up the chain while money flows down it.

A typical waiver names the project and property, the party giving up rights (the claimant), the party that paid, the amount, and, for a progress waiver, the date the work is covered through. It may also list exceptions: amounts the claimant is not waiving, such as retainage, change orders still pending or disputed extra work.

A waiver only affects lien rights for what it describes. A progress waiver for $20,000 of work through March 31 leaves your rights intact for April’s work and for anything you listed as an exception. A final waiver usually ends your lien rights on the job entirely, which is why it should be the last thing you sign.

The four types of lien waivers

Waivers vary along two lines. A conditional waiver takes effect only when the payment it describes is actually received; an unconditional waiver takes effect when you sign it. A progress (or partial) waiver covers a payment for work through a date; a final waiver covers the whole job. Together that makes four types.

Some states, including California and Texas, set out statutory waiver forms, and a waiver that doesn’t follow the required form may not be enforceable. Other states let the parties use their own wording. Names vary too: “release” and “waiver” are often used interchangeably, and “partial” means the same as “progress.” Check your state’s lien statute for which forms apply.

Why lien waivers matter to each party

For contractors, subs and suppliers

Your lien rights are your strongest collection tool, because a lien clouds the title until it’s resolved. A waiver gives that tool away for a specific payment. Sign the right type at the right time and you lose nothing; sign the wrong one early and you may have waived rights for money you never received.

For owners and homeowners

Waivers are the owner’s proof that the people who worked on the property were paid. Without them, an owner who paid the general contractor can still face liens from subs and suppliers in many states. Asking for waivers from each tier with each payment, and especially before the final payment, is the simplest protection an owner has.

For lenders and general contractors

Construction lenders usually require waivers before releasing each draw, since a lien can threaten the priority of their loan. General contractors collect waivers from their subs and suppliers so they can hand clean paperwork to the owner and get paid themselves. Missing waivers are a common reason a draw or pay application gets held up.

How to handle lien waivers step by step

1. Before the job starts, read the contract for waiver requirements: which forms, from whom, with which payments, and whether they need to be notarized.
2. Check whether your state requires statutory forms, and keep blank copies of the right ones on hand.
3. Send a conditional progress waiver with each pay request. Fill in the exact amount, the through date and the paying party yourself.
4. List exceptions on every waiver: retainage still held, change orders not yet approved, and any extra work in dispute.
5. When the money arrives, confirm it has cleared your bank, not just that a check was deposited or a transfer started.
6. Then sign the matching unconditional progress waiver for the same amount and through date.
7. Collect waivers from your own subs and suppliers before you pay them or pass their paperwork up the chain.
8. At closeout, send a conditional final waiver with the final invoice, and sign the unconditional final only after the last payment, including retainage, has cleared.

Keep a log for each job with every waiver you give and receive, the payment it matches, and the date the money cleared. When a question comes up months later, that log answers it in minutes.

A lien waiver example with numbers

An electrical sub has a $60,000 subcontract with 10% retainage. Each month it bills the work done to date, less retainage, less what it has already been paid.

After the first month, 30% of the work is done: $18,000 earned, $1,800 held as retainage, $16,200 due. The sub sends a conditional progress waiver for $16,200 through March 31. Payment clears on April 22, and the sub signs an unconditional progress waiver for the same amount and date.

After the second month, the job is 70% done: $42,000 earned, $4,200 retainage, $16,200 already paid, so $21,600 is due. The same pair of waivers follows. An extra $1,200 for relocating panels is still in dispute, so the sub lists it as an exception on both.

At the end, the work is complete and a $2,500 change order has been approved, bringing earned value to $62,500. Retainage is released, so the final payment is $62,500 − $37,800 already paid = $24,700. The sub sends a conditional final waiver for $24,700, and signs the unconditional final only once that payment has cleared.

The three payments add up to $62,500, the full subcontract plus the change order. If the $1,200 dispute is still open at closeout, the sub should settle it or list it as an exception before signing any final waiver.

Common lien waiver mistakes

• Signing an unconditional waiver for a check that hasn’t cleared. If it bounces, the waiver still stands.
• Signing a final waiver while retainage or approved change orders are still unpaid.
• Leaving the amount or through date blank, or letting the paying party fill them in.
• Forgetting exceptions, so a progress waiver quietly gives up pending change orders or disputed extras.
• Using a homemade form in a state that requires a statutory one, or accepting one as the owner.
• Signing a waiver that releases “all claims,” not just lien rights, without having it reviewed.
• Paying your own subs and suppliers without collecting their waivers first.

Most of these come from treating waivers as routine paperwork signed in a hurry to get paid. Read each one, check it against the payment, and keep the copies together.
