I need help please. A subcontractor filed a lien on my property. The general contractor (who was sent by my homeowner insurance) didn’t pay and went out of business. I never got a pre notice about this lien. He’s filing for labor only but he brought material to do the project at my house. The initial invoice to the general contractor was $1900 and now he’s claiming $2900 because 4 months has passed. Is this legal? Can this lien be invalid?
