How do I force the bank to release funds that was left to me by my mother?

When my mother died I was young and left the money to me but because of my age the attorneys put it in a bank, and put a court order on it to be released to me upon the age of 18, literally what the judged ordered and the bank is telling me the court in another state that I live in has to order it open, so now I have to pay out of pocket for what I work to get money.
