DH thinks if they have put a brick fence in that they more than likely would have used a surveyor to find out where the line is. He strongly suggests you talk to the builder, or the owner of th property first as they are responsible and go from there because they will definitely know what has happened. (He said there may even be survey pegs around that you can see, metal pegs in the ground which can then measure the line. The title line is on your actual title - tricky to measure up yourself but the builder should have done it.) Good luck hun - Im off to bed but let me know how you go tomorrow. xoxoxo
