Even if you could get an emancipation order at 18 (or older), it still wouldn't make any difference to FAFSA. The law is specific in FAFSA, you must be an emancipated MINOR. The fact that your parents won't contribute to your education (or other living expense) is NOT eligibility for financial aid by itself unfortunately. In fact, lots of kids graduate high school and end up paying their own way through school. I didn't live at home at all once I graduated HS. The word is "get a job" and "study hard." Financial aid isn't a right (at least under the current scheme, but I did read a recent study that said if we just abolished the current federal fin/aid system and gave the money directly to the universities, there'd be enough money in the budget to cover everybody's tuition).
As stated, emancipation (in the legal, not FAFSA sense) has nothing to do with proving you're financially independent. It's recognition that an independent living minor needs relief from the "disability" of entering into contracts that is necessary for his continued independence. It's perhaps one of the most misunderstood concepts of young people The only definition of the word emancipation is from their 8th grade US history study of the civil war.
