Just bought a house in town last fall. I am installing an invisible fence to contain our Lab puppy. My neighbor is giving me all kinds of grief about the boundary lines stating the one corner post is inaccurate. I moved my IF in 2 yards to appease him. How close to the boundary line can I legally place the fence. The former owners had a survey done before selling the house and the surveyor placed all corner posts where they're at now- could my neighbor be right about inaccuracy?
