A GC I've been working with on a house renovation made up lots of charges at the end of a job- first it was 12k, then 15,500k then he made up 20,5k. I've asked him over half a dozen times to show me any signed change orders, and upfront change orders, any receipts any proof of expenses and he has failed to provide any. In addition the contracted he work he did many issues required redoing, hiring new people to tear up what they had done improperly and redo it all at my expense. I detailed all of these expenses- he refuses to accept any of them. Further, he failed to do things I had contractually paid for- like hooking up the washer and dryer-(which mean plumbing it and running electrical to it) I never signed a single change order for any of the work, but have paid him 10k- all of the parts of the final overages that I was actually responsible for. He used your site yesterday- well past 90 days from the end of the job - to file a lien against me. The lien is out of State. I've tried calling to find out if his contractor license is even valid- as there isn't one listed. His address appears fake as no record of his business exists online. I'm very confused as to how to proceed. Your help would be appreciated. Many thanks, Clay
