The dad's trying this 'freedom' but he knows that he can deliver an ultimatum to his son.
My one question would be whether or not he has someone to look after his home and matters pertaining to his son now, while he's alive, not just after he's gone. He could be sick at home, sick in a hospital, or just decrepit, unable to deal with his son, all sorts of situations. A lawyer or bank who can hire someone to have some power of attorney for some matters. I'm guessing he does, but you could ask.
