Can I file a lean on a job if a customer stemer says they wanna fire me and it and has somebody else finished it after he tried to finish a sidewalk and in both the driveway inside won't look like crap so now he owes me $6000 don't want to pay? And I have a written contract he says I broke contract because I waited a week to pour because of the rain but in my contract it stipulates about the rain if it's raining he has a sign of waiver saying I'm not liable for damages calls by the rain
