Old fences will absolutely stand up in court as the line , especially if they've been there many years and it can be proved previous owners were in agreement . New owners getting a survey after they purchase is like closing the barn door after the horse is out. Lawyers love surveyors , they're good for business .
Also surveyors can enter property to do survey work without permission, it's the law.
Old fences i can say by the hard way. That is not always true . It all come down to what the judge says .
