I am sorry you are in this situation.
I think that it will be difficult to get an non-custodial parent waiver (NCP) waiver since your father is partially supporting you.
Are there any legal proceedings that document abuse? Can your GC write about this in their rec letter?
You can certainly try and submit an NCP waiver, but the odds are stacked against you because your dad is in your life and contributing money.
As thumper said, there are two highly selective schools that do not require NCP financials…U Chicago and Vandy. (Vandy does reserve the right to ask for NCP financials though) Are those schools on your list? If not, it might make sense to take a look at them.
You are going to need to have an affordable school, or two or three on your list…FAFSA only schools. And even then, your mom will need to report the support she received from your dad. What is your state flagship school? What can you and your mom pay for school each year?
