I'm 17 and I only live with my mother but i want to move to another state. I have less than six months before my 18th birthday but I feel like I can't live a day longer in the same house as my mom. We argue about every thing. I am not abused. I stay home all day every day and I would like to move back in with my sibling. She's willing to take care of me and pay for whatever is needed. If I move out in a couple of days to my sister's in a different state can police officers force me to return to my mother's. I am not looking for a lawyer just need to know the law.
Talk to your mom. Ask her to let you move. If she says "no", you've got to wait until you're 18. You're still a minor. Don't put your sister in the middle.
I am not intending this to be legal advice, because I don't know the particulars of your situation. Call me if you would like to discuss this or other isues.
