You would need to appear before a court judge (a local courthouse would work) and explain that you have been living on your own for 2+ years with no support from family. They should grant you a legal family emancipation so you can file independently.
I recommend staying as professional as possible and including things such as a copy of your pay stubs will likely help out a lot.
Just explain that you go out of the way to care for your son and that you request that you be given the maximum amount of financial aid to ensure that you can continue to focus your financial energy on him and be able to study and get good grades with less stress.
Well, he's an ***hole isn't he?
In order to maximize how much aid she can receive, I recommend having her look into getting a legal family emancipation. It basically just declares her legally independent so she can file as such on her taxes and on the FAFSA.
You still are required to list their information until you are 24 or meet one of the above criteria.
If your father makes too much money and will not help you with school costs, then yes, I recommend looking into the emancipation process.
What do you think of this post guys?
Can you file just with your mother's information? It sounds like she files as Single anyway, so you shouldn't have an issue if you only list her information and pretend your Dad doesn't exist as far as taxes go.
If your parents are resident aliens or citizens as well, then you still are considered dependent until you are 24. If they are not, you can file safely as independent.
