# Lien Waiver

In the mechanics lien process, a lien waiver is a document from a contractor, subcontractor, materials supplier, equipment lessor or other party to the construction project (the claimant) stating they have received payment and waive any future lien rights to the property (of the owner) for the amount paid. There are typically four types of lien waivers: Conditional waiver on progress payment – The safest waiver for claimants, this waiver generally specifies that if they have indeed been paid to date (and that includes no return or stopped payment checks) the waiver is an effective proof against any lien claim on the property. Unconditional waiver on progress payment – This waiver releases all claimant rights through a specific date unconditionally (and that includes no return or stopped payment checks).
