When "an elderly person with a joint bank account dies, do the funds belong to the decedent's estate or do they belong to the additional signer as a co-owner of the account?" A recent California Court of Appeal case held that "[s]ums remaining on deposit at the death of a party to a joint account belong to the surviving party . . . as against the estate of the decedent unless there is clear and convincing evidence of a different intent." This is a basic or black-letter rule, a clear statement of the law. It is also a trap for those inclined to seize upon a seemingly clear explanation of the law that leaves no room for interpretation or nuance.
