The neighbor is now in the nursing home and the son inherited the property. He had it surveyed because he wants to subdivide the house and land. The surveyor told him our fence is on his land by 0.2 something., but the surveyor put metal post in what was our yard that appear to be 10 to 15 inches off the fence. on our side Now the son wants us to sign a paper stating that we are leasing the land because he doesn't want us to have to tear our fence down.. Does this sound right?Should we sign?
