am i legally entitled to money.given to me.when.i was 13

It depends on how your father held the account.  If the money was held ina formal trust, then you have to look at the terms of the trust.  If however, he just took the money from you, invested the money in an account without your name on it, but supposedly doing it for you, then you might have difficulty proving the money was yours.  There is a law - Uniform Gifts to Minors Act, UGMA that governs how accounts can be held for minors.  If your dad deposited the funds in your name when you were 13 you are now entitled to that money.  But if he did not, I don't think you will ever be able to get paid.
