Why they exist
Contractors, subcontractors and suppliers may have a right to file a lien against a property when they are not paid. Owners and lenders want proof that bills were paid, so each payment is accompanied by a waiver. It reduces surprise claims at closing.
Lien law is state-specific, so details change by location. Treat this as general information.
Conditional waivers
A conditional waiver says the signer gives up lien rights only if they actually receive the payment described. It is usually signed before the check clears and is the safer form for the person waiting to be paid.
Read the amount and the date range. A waiver that covers more than the payment received may waive too much.
Unconditional waivers
An unconditional waiver takes effect when signed, whether or not the payment arrives. It should be signed only after the funds have cleared or been received. Signing early on a promise can leave a contractor with no remedy.
Final waivers release all rights through the end of the job, while progress waivers cover only a period.
Notarization and recording
Some owners, lenders or states ask that waivers be signed before a notary. The notary identifies the signer and completes the certificate, without judging the content. Certain releases of liens are recorded with the county so the public record shows the claim was cleared.
If you need a recorded release, check how the county accepts documents.
Mistakes to avoid
Do not sign a waiver listing a larger amount than you were paid. Do not leave the date or project blank. Do not sign on behalf of a company without the authority to do so. For subcontractors, make sure the name matches your invoice. Owners should keep the full set of waivers with the project file, since they may be needed at refinancing or sale. For any dispute, speak with a construction attorney.
A project example and layers of the chain
A homeowner pays a roofer a progress payment. The roofer signs a conditional waiver for that amount and date range, then an unconditional waiver once the check clears. At project end, a final waiver releases claims through completion. The homeowner keeps all three.
When the home is later refinanced, the lender asks for proof that contractors were paid. The file answers the question.
Waivers can come from subcontractors and suppliers too, not only the general contractor. An owner who pays the general in full but never collects waivers from the lower tiers may still face claims. Ask the contractor for waivers from each tier at every payment.
Owners should hold back final payment until the final waivers are in hand, and keep a simple log showing who was paid, how much, and which waiver covers it. Contractors, for their part, should keep copies of every waiver they sign. If a form looks different from a state-approved version, ask an attorney, because some states require specific wording for a waiver to be valid.
Common questions
Do I need a notary for a lien waiver?
Only if the form, the owner, the lender or state rules call for it. Many waivers are signed without notarization.
What is the difference between a lien waiver and a lien release?
A waiver gives up the right to file a lien in the future. A release clears a lien that has already been filed.
Can a notary draft a waiver?
No. Notaries do not prepare legal documents for others unless they are also licensed to do so.
