When we closed on our house last week we got a copy of the survey for our property that the appraiser uses. However, our lawyer told us NOT to user that plot plan if we were putting in a fence. She said we need to go to the town hall for that. I think she said that they will have plot plans on file there, but that your should always get a survey guy in before placing a fence. (I'm sure your town/city hall can point you in the right direction). We're not replacing and extending the fence til next year, but I can't wait for a new fence-GL.
