In Ohio ex husband recently deceased and ex wife still listed as beneficiary on payable on death savings account so can she collect?

The ex-wife should consult with the attorney who represented her in the divorce proceeding. Generally, a divorce decree includes an agreement that all matters have been settled between the parties and neither party will make any future claims against the estate of the other. The ex-wife should determine if that would include the POD bank account. If not, then she should collect the savings account balance without delay.
