Legally you cannot move out until you are emancipated. A petition for Emancipation has to be filed in the Juvenile Court. You have to prove that you are able to support yourself. Your parents have the right to be noticed and to object. By the time a hearing is set, you might be 18. Alternatively, talk to your mom about your plans calmly and maybe she would appreciate the opportunity for the two of you to have a better relationship so long as you are moving to a safe environment.
