My landlord had a plumber doing some work in the front yard of my house. There was a very large hole in the front yard that the plumber had dug to work on the broken pipe. Though the plumber covered the hole with very thin plywood he did not mark the area with cones or tape it off. I came home late at night in the dark, didn't know the hole was there and fell in. I had a previous back injury that has been reinjured. I went to the doctor after the accident and am going to need further medical attention. I am going to make a claim but am not sure how to go about it. Do I start with my insurance, my landlords or the plumbers? Or all 3?
Thanks!
