I am having difficulty obtaining my settlement from a case when I was a minor. The attorney won't help me and the bank has no record of me.

Do you have any paperwork related to your settlement?  If you were a minor the court would have likely entered an order and the order would have included instructions for your share to be placed in trust for you.   The attorney who handled the case should certainly help  you and you should go back to that attorney. Tell them if they do not help you, your next phone call will be to the local bar association to report him or her and make a claim as to a fee dispute.  If you have a basis, the employees of the bar association will help you from here.   Best of luck to you.
