We started a solar commercial project 5 weeks ago. Our scope of work as grown as the General on site needs more work done that we can perform. The payments are starting to slow down and I’m worried that we will not get all of the monies due to us at the end of the project. Is it too late to file a lien? With every different task we have been asked to do I do stop work until we get a contract from the general, but I am being told that you have to file one before you even show up on site.
