Our next door neighbor is putting up a fence because their dog bit a woman who owns the vacant lot on the other side. Trust me, I am happy about the fence but I still have issues. In the process of getting started they had a survey company come out. The survey company is saying our property line is about 4-5 feet farther towards our house. They found a metal pole under our driveway (which we happened to put in when asphalting our original drive way) and are claiming that is the original corner marker. Not only did they dig under our driveway but this also puts our privacy fence in our back yard over the property line. The surveyors also claim there is no vacant lot but I saw the plot map when she brought it to me in an attempt to sell it to me a while back and I remember when she bought it. Do I hire my own company in the hopes they were wrong or will they just side with the first one. Are surveyors biased towards the one who hired them? Any one know an approximate cost?
