Hello, We completed a project more than 150 days ago. We were approved for a change order for additional work by the General Contractor in writing. The General Contractor is refusing to pay us because the project Owner is refusing to pay them for our and other subcontractor change orders. We were just informed of the project Owner refusing to pay. Up til this point we were told that all parties were working on it and that payment was expected to be made. I understand that the State of Wyoming requires that the mechanics lien be filed within 150 days from last working on the project. This date passed before we were notified about the Owner refusing to pay. I spoke with a different general contractor and they think that because we were told that we would be paid up until after the 150 days expired, that the 150 days to file a lien should start essentially now. What are your thoughts?
