Legal Question in Family Law in Illinois

The "formal" process is to seek emancipation through a court proceeding, but that will depend on whether you will be able to support yourself or have people who are willing to take you in and support you. Another issue is whether you have finished high school yet because parents are on the hook too if you're still 17. So if you want to consider moving out and it is NOT an emergency situation, you'd best be advised to talk to a lawyer and figure out how to accomplish your goal. I applaud you for at least asking.
