Ah, but I didn't lose any of my land at all. I didn't move the boundary, did I? I just built a fence on my land.
The beauty of that was the owner of the house next door, when he refused to go halves with me on the new fence, said I owned the old fence, and put it in writing in an email.

Not necessarily.
When the landlord who owned next door, refused to go halves with me on a fence, I built the new fence on my side of the existing old, delapidated fence, so that the old concrete posts remained as the boundary.
