At most colleges you would have had to provide both parent’s income information for the awards you already received. If you had previously provided both parent’s info, then there shouldn’t be a problem - though your school may recalculate current or future awards based on 1 parent rather than 2. If your school requires both parent’s info and you had previously applied with only your mother’s info there may be a problem.
Either way, the only way to get a definitive answer if from you school’s fin aid office.
