Can I legally move out of my mothers house to my fathers? I'm 14, and my older sister already moved out of my moms several years ago to live with my dad. My mom is bipolar and we think she has other mental problems as well, but she won't get tested. She is always screaming about something and telling me how worthless I am and cussing at me all of the time. She used to hit my sister when I was little but we don't have any proof. Where should I get started to move out? She is doing the same thing to me that she did to my older sister that caused her to move out.
