Final lien waivers

Final lien waiver: what it covers and when to sign it

A final lien waiver releases all of a claimant's remaining lien rights on a project in exchange for the last payment, including retention and change orders unless they are listed as exceptions. Exchange a conditional final waiver for the final payment, then collect the unconditional final waiver once that payment clears.

What does a final lien waiver cover?

Everything the claimant furnished to the project, apart from the exceptions written on the form. Unlike a progress waiver, it is not limited to work through a date.

Progress lien waiver compared with final lien waiver
	Progress lien waiver	Final lien waiver
Covers	Work through a stated date, for a stated amount	All work on the project
Retention	Usually not covered	Usually covered unless listed as an exception
Pending change orders	Not covered	Covered unless listed as an exception
Exchanged for	Each progress payment	The final payment (often including retention)
After signing (unconditional)	Claimant keeps rights for later work	Claimant has no lien rights left on the job except listed exceptions

The exceptions line is what protects a claimant who still has a disputed claim at the end of a job. California's statutory final forms, for example, say the document “does not affect” disputed claims for extras in an amount the claimant fills in. Generic final waivers should have the same thing; see our conditional final and unconditional final templates.

Conditional vs unconditional final lien waiver

The conditional final waiver only takes effect when the final payment clears; the unconditional final waiver takes effect on signing. Exchange the first for the final check, and the second only after the money is in the account.

The order matters more on a final waiver than on any other. Signing an unconditional final waiver before being paid can leave a claimant with no lien rights at all on the job. The same logic as for progress payments applies; see conditional vs unconditional lien waivers.

Not every state splits final waivers this way. California, Texas and Arizona each have statutory conditional and unconditional final forms. Florida and Georgia each have a single statutory final-payment form, with their own rules on when it takes effect. Check lien waiver forms by state before using a generic form.

When should a general contractor collect final waivers?

Before releasing the final payment or retention to each subcontractor and supplier, and before the GC submits its own final payment application to the owner.

Confirm the subcontractor's scope is complete and the final amount, including retention and approved change orders, is agreed.
Collect a conditional final waiver for that amount, plus waivers from known lower-tier subcontractors and suppliers on exposed jobs.
Release the final payment against the conditional final waiver.
Collect the unconditional final waiver once the payment clears.
Assemble the closeout package for the owner. On AIA contracts this often includes the G706 affidavit of payment and the G706A affidavit of release of liens, with the waivers attached.

According to AIA, the G706 is “typically executed as a condition of final payment,” and the G706A is used when the owner wants a sworn statement that all releases or waivers of liens have been received.

Common final lien waiver mistakes

Releasing retention without the final waiver, accepting a progress form at closeout, and signing unconditional before the funds clear.

Releasing retention first, waiver later. Once retention is paid, the payer has little leverage to collect the final unconditional waiver.
Using a progress form for the last payment. A progress waiver only covers work through a date, so retention and late change orders stay open.
Leaving the exceptions blank by accident. A claimant with a legitimate disputed claim can lose it by not listing it.
Forgetting the lower tiers. Suppliers and sub-subcontractors may have their own lien rights; one final waiver from your direct sub does not cover them.
Confusing a final waiver with a lien release. If a lien was recorded, you also need a recorded lien release.

How to make final waivers part of closeout, not an afterthought

Treat the final waiver as a payment requirement on the final invoice and on the retention release, so the payment cannot go out without it.

The lien-waiver risk assessment includes a question on documentation before retention release, and the waiver collection workflow shows how general contractors tie waivers to each payment.

Frequently asked questions

What is a final lien waiver?

A final lien waiver is the waiver a subcontractor, supplier or contractor signs for the last payment on a job. It releases all remaining lien rights for the work on that project, not just the work through a billing date, except any disputed claims it lists as exceptions.

When should a final lien waiver be signed?

The conditional final waiver is exchanged for the final payment, which usually includes released retention. The unconditional final waiver should only be signed once that final payment has cleared.

Does a final lien waiver cover retainage?

Usually yes. Because a final waiver covers the whole job, it typically releases rights to retention and change orders too, unless they are listed as exceptions. That is why a claimant should list any amount still in dispute before signing.

What is the difference between a final waiver and a progress waiver?

A progress waiver covers work through a specific date and leaves later work, retention and pending change orders untouched. A final waiver covers everything on the job, apart from the exceptions written on the form.

Is a final lien waiver the same as a lien release?

No. A final lien waiver gives up the right to file a lien. A lien release cancels a mechanic’s lien that has already been recorded. If a lien was recorded during the job, you need a recorded release as well as the final waiver.

Aequo Build

Stop paying subs before the waiver is in.

With waiver enforcement on, Aequo Build creates a conditional waiver requirement for each subcontractor payment you make from Aequo, holds that payment until a reviewer verifies the waiver or an approver records a reasoned override, escalates overdue requests to the subcontractor and your team, and requests the unconditional waiver once the invoice is paid. It works with QuickBooks Online.
