I'd be inclined to encourage the non farming brother to find a place of his own. Just because he doesn't want to move out of his parents house, doesn't mean he shouldn't - unless he has extra needs in which case provision should be made for him. Surely he sees friends moving on, gaining independence and possibly settling down with their own family. Does he plan to stay at home forever? What happens if the farming brother gets married? He'd surely need to move on then. He's not likely to win in this scenario. Your parents are entitled to leave their farm/house to whoever they want. Harsh as it may sound, assuming he is a heathly, able bodied, working adult then he really needs to take responsibility for his own future and stop relying on his parents to provide for him.
