 then your wife wouldn't be able to sell the house without going to court and having a special hearing to get her permission to sell it, which nobody wants to have to go to court more than they need to. So there's lots of reasons why you still need a will when you are married without children. A question here off the text line. So if a trust is set up, is there still a person in charge and can they change or control it? Example, a mother with a big estate where kids don't get along or trust one another.
