I am a contractor who has not yet been paid in full for our work. The customer states he will not pay until he has lien waivers from all of my subcontractors (who I hired and paid myself) as well as my company. He insists that he has the right to receive this waiver before he will pay. In WI statutes 779.05 (2), it says "a lien claimant...is entitled to refuse to furnish a waiver unless paid in full for the labor...to which the waiver relates." Who's right? Payment first and then a signed lien waiver?
