Quoting snglemama:" unless it's recently changed... GA you can move out at 17. Anything before your 17th birthday they can put you in youth detention center for running away. "
DH is a cop. A few weeks ago (can't remember the date to be specific, between Thanksgiving Day & Christmas Day) had a call dealing with this. A 17 year old male left on his truck, that was in his name, and he paid for. His dad said he couldn't go, and he just walked on out. So his dad called the cops, they dispatched DH, and that's what would've happened. I don't know if it's changed recently, but he's pretty straight up on what is/isn't legal...Constantly keeping up with it.
