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:
In the United States, some states only use a conditional waiver on progress payment and an unconditional waiver on final payment.
The mechanics lien process can be of great value to claimants in enforcing their claims, if done according to the laws of the various states, or the federal government. These parties are entitled to be paid for their material or labor contributions to the improvement of real property. Most forms for the process can be obtained from local office supply stores, and a few computer programs exist to handle the process on a nationwide basis.
