There is a statute of limitations on collecting debts. Remember, that statute lasts either four years or six years depending on the state you're in. Once that statute is over, you can no longer be forced legally to pay the debt. Take care. If you make any kind of payment or promise to make a payment, the statute starts again and now you're on the hook for another four or six years. So, once that statute is over, you can not be sued to pay the debt.
