ClaryS, if they are all pensioners, as I am assuming they are, then Anne wouldn't have to sell their house as she would still be living in it. And this country cannot afford free nursing home care, we're broke.
Nevertheless I take your point, it isn't fair that those who make no provision for themselves get theirs paid for by the rest of us. When my mother died we eventually had to sell her house to pay her NH fees after her savings ran out. Yet a friend of mine who had got her mother to sign her house over to her about three years before she died, never paid a penny. Unlike when my mother died, the council went into every detail of my mother's finances, where my friend's local council merely asked does your mother own a property to which of course the answer was No so her fees were paid in full. No further questions asked, she didn't even have to lie! This was years ago and I'm still annoyed about it. No wonder her family are now millionaires.
