In order for you to operate as an adult, you may file a Petition for Removal of Disability of Minority in the county where you live. In order to file, you must be living apart from your parents, guardians or managing conservators and you must be self-supporting and managing yoru own financial affairs. If you do not meet these requirements, my advice, though not legal advice, is the same as what I did at 17 and most other 17-year-olds who wanted their independence. Buckle down in school and the best grades possible. Find a good job as close to home as possible to earn money and gain valuable employment skills. Stay out of trouble and don't get a criminal record of any kind.
