You need to be 18 or otherwise emancipated to petition for a name change. You can file a name change on your own and only pay the court costs of maybe $160 or so. It's easier to hire an attorney to do it for you and, depending on what you want to change your name to and why you want to change it, an attorney might tell you that you're wasting your time OR help you get it done right the first time.
Here is a helpful guide if you want to do it yourself.
