Can a subcontractor (Asphalt Company) file a mechanics lien against a commercial property for resurfacing a business driveway that PG&E dug holes in to replace gas lines. PG&E (Calif.) gave them instructions to resurface the whole driveway and not just the small areas where they dug the holes. Do I have any recourse to block or remove their lien if they file one. Nothing has happened yet. Larry G
