This probably won't be possible, no matter what state you are in. For more state-by-state information, or perhaps even some legal help, you could try the Juvenile Law Center. The child emancipation page is linked to the right.
That is not possible.
In the few US states that allow the emancipation of minors a petition must be filed in the state court of the county where the minor resides.
A court date is set for a judge to hear and rule on the emancipation petition and for all involved parties (parents, authorities, counselors, etc.) to be allowed to agree or contest the action.
