well it seems she must already have the permission to go ahead and is now going to something that is more close to the value of hers . But I wonder if the la can do anything after she has bought a new place even if there are no funds left over, and also what happens when he dies? Will they try and make her sell her new place to get the money off her for his care which is being partly funded?
As long as she puts both their names on the deeds and if there is any money left over she divides that and puts half into his account she will have nothing to worry about. The house is disregarded because she is his wife so needs the house to live in. That in itself is a bonus.
