Can a parent withdraw money from a child's savings account without consent?

My parents opened a savings account for me when I was little so that I would have money for college. Recently, my dad has been reluctant to use that account and I've been wondering whether or not I still have money in it. I also have money that I received from my mom's social security that was supposed to strictly be for me and my college tuition (she had made it so that all of the checks that we received would be for me). Is it still possible for my dad to have taken money from my account, even though the money that was put there was supposed to be for me?
