In most states, the circumstances in which a minor becomes emancipated are enlisting in the military and marrying, both of which require parent or guardian consent, or obtaining a court order from a judge.
The exact laws and protocols for obtaining emancipation vary from state to state. In most states, the minor must file a petition with the family court in the applicable jurisdiction, formally requesting emancipation and citing reasons why it is in their best interest to be emancipated. The minor must prove financial self-sufficiency. Many states require that the minor has been living separate from their parents or guardians for a period of time; however, consent of the parents or guardians is necessary in order to avoid being classified simply as "running away."
Colleges are quite aware that students try to get "emancipated" in order to get more grants, loans and scholarships. Most colleges will not recognize emancipation for financial aid purposes unless there is a court order for abuse. FAFSA also does not recognize emancipation. Your parents still must file their financial disclosure form in order for you to be considered for government aid.
They've seen that before.
