I realized that I have been making the same mistake on my FAFSA applications for the past 3 years.

Nope. I stopped depositing my money to that account after I opened up my own account with a different bank. However, I still continued to use money on that account whenever my mom wanted me to buy groceries for her or something. That account is under my mom’s name and mine. So how is the department of education supposed to tell if that is my money or my moms? What if they think it was my money and go after me for failing to declare it on my FAFSA application.
