Irrevocable will vs account Ownership
My uncle drew up an unrevocable will years ago and recently wanted to change it, however he could not. He wants to leave his only living sister his money, so he has put her on a joint account with him. If he should die, the money in the account would be in my mothers name. Could the people in the will (whom my uncle has not seen or heard from in 20 years) contest this, or does account ownership override a irrivocable will? The will was made in Arizona State, he is now a Washington State resident.
