Do credit card companies have a valid claim against estate

While as a courtesy credit card companies often waive interest after the date of death, like any other unsecured creditor, a credit card company has a claim against the estate which must be paid before the real estate or any other property can go to the benefciaries under the Will.  Some states have rules as to the order in which debts must be paid and rules about how and when claims should be submitted.  Please consult your probate attorney about the rules in Ohio.
