How much are you making at your full-time job, and how are your grades impacted by your full-time work?
How long have you been living completely apart from your parents and how long have you been supporting yourself 100%? Oh, oops, you still live with them and are still being supported.
The law is
here, and you'll note that it discusses NEED for emancipation. You - like every other teenager in existence - think your parents are unreasonable. They've probably said "My house, my rules. If you don't like it, get out.", and you want to say "They're kicking me out!", when what they're really saying is "Get it together, kid."
You don't NEED emancipation. You WANT it, and that's not going to hold any water with the courts.
