My mom says i cant move out until i graduate. And i am 18. She says she has papers saying i cant until graduation. But my dad''s papers don''t say that.

It is impossible for a lawyer to advise you without reviewing all of the documents involved.  Based on your note, it would appear that you would like to move out of your mother's home, but it is not clear if you intend to continue in high school until graduation.  If you don't graduate from high school, you will have a harder time of making a decent life for yourself than if you stay i school.  But once you move out, how will you support yourself.  Perhaps you should talk to your father and mother about your concerns.  In any event, there are not that many months left in this school year.  (It may seem a long way off, but it isn't.)
