Yes, I have done my initial research.
The state is Maine.
Ed owns a piece of land, on which he lives. George owns the land beyond Ed's. George's land is completely undeveloped. George's land can only be reached by crossing Ed's. Repeat, George's land is completely undeveloped. He does not live on the land in question. Ed does live on his land.
Prior to George taking ownership, Ed had always permitted people to cross his land to reach the undeveloped area. (It's a favorite make-out spot overlooking the water.)
Let us suppose that Ed has permitted this for the 20 years required for an easement to be established. Ed dies and in his will, leaves his land to Jesse. Can Jesse put up No Trespassing signs and block any further access?
Now, same question, but with Ed only having permitted the access for 15 years.
I just want to be sure I'm clear on what easements do and do not permit when property changes hands.
