I'm a commercial painting sub contractor working at a U of M building in Michigan. I'm completely done with the project since December 31, 2021 and have been paid for all except our 10% retention. The General Contractor is saying that the owner will not pay out retention until two change orders are dealt with for another sub contractor (not us). This project started back in early 2021 and I don't see that the Office Manager at that time sent a Notice of Furnishings. Do we have any lein rights to collect our balance?
