An unconditional lien waiver says the signer has been paid and gives up lien rights for that amount, effective immediately, whether or not the money actually cleared. It comes as unconditional progress (for a payment through a date) or unconditional final (the job is paid in full and all lien rights are released). Because it offers no protection if payment fails, it should only be signed after funds are in hand. Lien law varies by state; this is not legal advice.
Why it matters
Owners, lenders and title companies treat unconditional waivers as proof that the money reached the people who did the work. The final unconditional waiver from every sub and supplier is usually a closeout requirement before retainage is released.
Worked example
Illustrative: after the GC on Riverside Medical Center pays Pay App #8, the lender asks for unconditional progress waivers from each sub for the amounts paid. Apex Steel and CoreDry haven’t sent theirs (sample data). The lender may hold part of the Pay App #9 draw until they do, which is why the GC’s AP team chases them now, not at closeout.
Common mistakes
- Signing an unconditional waiver before payment clears.
- Collecting unconditional waivers that cover more than was actually paid.
- Missing sub-tier suppliers, whose lien rights are separate from the sub’s.
How os.construction handles it
We’re building waiver tracking linked to each AP payment, so a payment that has cleared without a matching unconditional waiver stays visible until it’s collected.
