Licenced Contractor provided an estimate of 475 after looking at my property. After they were done presented me with a 3800 bill. They performed work that was never approved by me. I had previous companies estimates that were lower and would not have retained the Contracter had i known. Long story short he has threatened to put a lien on my property. Invoice was provided 3 wekks later after several request because I was not able to validate the work under the house. Can a contractor file the lein when I never approved for the work or the amount? They have sent me a Notice to Intent to Lein. Is a consumer protected from a fraudulant lien?
