Do You Need to Have an Unconditional Lien Release Signed?

An unconditional lien release is not binding unless the claimant signs and delivers it, according the California Department of Consumers Affairs' Contractors State License Board. An unconditional lien or waiver is a legal document that helps a claimant receive money owed for products sold or services performed.

Liens are most effective when issued after the filing of either a conditional waiver and release upon progress payment or an unconditional waiver and release upon progress payment form, explains the California State License Board. The releases are only effective if the customer makes or arranges some form of payment to the claimant.
