Our company is a labor only company. We started a job that required a 3 draw payment. While doing work at the home the clients request for additional work to be completed which turned our now 3 draws to 4 draws. The client has paid 2 of the 4 draws, we have requested for the 3rd draw to get us through the remainder of the job until completion where the 4th & final draw will be processed. Clients are refusing to pay that 3rd draw which forced us to stop working. Are we able to file a mechanics lien on the clients property?
