My husband and I are building a home with a custom builder. Can we require that the custom builder provide us with a lien waiver from the various contractors as the project moves forward. We have a draw schedule for specific phases of completion. Unfortunately, we did not put anything in the contract and cannot hold any portion of the draw. Is it too late to require the waviers? Our builder hasn’t been on the up and up with different phases of the process and we are getting concerned that we have anything to stand on. Thanks
