I'm a general contractor on a commercial project. The owner signed a contract/ proposal for the work I performed. I now need to file a lien and a notice of intent. Does the sign contract work for a preliminary notice? The owner is trying to sell the business quickly to avoid paying the contractors. I have finished the notice of intent but I'm wondering if I'm waisting my time? Why would you need a preliminary notice when you cant predict the future? Isnt a signed contract legally binding?
