I have a small parcel (1 acre) that was surveyed 7 years ago (without my knowledge) by a neighbor who "thought" she had an egress easement (not on deeds, etc) going back almost 4 decades, unknown by anyone but "her".... and relatives long passed.
She learned....quickly.
Now I want to mebbe redraw the lines with another neighbor (adjacent to both)....
That was a $1600 (waste) for the egress neighbor....too bad. I won't pay that much to do what I'd like to do...should be easy-peasy....but I dunno?
I have a surveyor lined up for some other properties...ask him, or try to use the surveyor that did it 7 years back? I have no problem paying (neighbor/surveyor)....just see no need to do it ALL again. What say ye? Thanks!
