We had a major argument with our neighbors about our property line. They think they own about 6-8 feet of our property. We asked our former neighbors just to be sure and we watched where the pin was to make sure we were not putting our fence on their property plus we put the fence 2 feet away from the pin in the road to make sure. He wants to have the land surveyed and that's fine because I would love to to show them. What I want to know is how long do you have to take care of and use the property before the "grandfather Claus" takes effect?
