We worked as a sub-contractor under a General Contractor on a project, and the General Contractor had us sign a unconditional waiver and release on final payment form even though we have not been paid anything on the entire project yet. I have the document we signed, does that waive our rights to file a mechanics lien. I have an email stating that from the GC, and we wrote on the unconditional waiver that they owe us the total dollar amount. Mechanics Lien Rights?
