On any construction project, lien waivers exchanged with payments are what keeps the title clear. Handled loosely, they are the reason a sale or refinance stalls.

Four standard forms in most systems: conditional and unconditional, each either partial or final. Conditional waivers take effect only on actual receipt of payment; unconditional ones take effect immediately and should never be given before funds have cleared.

The common error is providing an unconditional waiver against a check that has not cleared, or in exchange for a promise. The lien right is gone and the payment risk remains.

Statutory forms. Several states prescribe the form and provide that non-conforming waivers are unenforceable, or conversely that any deviation is strictly construed. Using a national form in such a state can invalidate the waiver.

Through-date discipline. Waivers should state the amount and the period covered. A final waiver given while retainage or change order claims remain outstanding waives them.

Lower tiers. An owner paying a general contractor is exposed to subcontractor and supplier liens. Collecting waivers down the chain, and using joint checks where credit is doubtful, is the control.

Records. A payment file with the application, the waivers for that draw, and the lien search updates is what supports a title company’s willingness to insure over.
