Unconditional Lien Waiver

A waiver effective immediately on signing — even if payment never clears.

What it means

An unconditional lien waiver releases lien rights immediately upon signing, with no condition attached — if the check later bounces or the payment never arrives, the waived rights are generally still gone. It is meant to be signed only after payment has actually been received and cleared. Some states require statutory forms with specific warnings on unconditional waivers; requirements vary by state.

Why it matters before you sign

Signing an unconditional waiver before the money clears trades your strongest collection tool for a promise — if the payment fails, you may have waived lien rights for money you never received.

In a contract, it looks like this

Only after the wire posted did the supplier sign the unconditional final waiver covering the whole account.
