So me and my parent are living with my grandparent, but due to extreme circumstances, my grandparent pays for the bills. All of the bills, including rent, are under my grandparent’s name, so do I have to put in my grandparent’s information whatsoever into the Fafsa?
You use your parent information only on the financial aid forms. Not your grandparents.
BUT if your parents really have $0 income and don’t pay any bills…be prepared to explain how your family pays day to day living expenses…because likely, you will be asked.
