Do both my dad an I need to fill out the Fafsa?

I started mine but never finished it. My dad is working on one now for my brother and I. Do I need to finish mine or is whatever’s my dad does sufficient?

You and your brother will each need your own FAFSA. You will need your own FSA ID to sign your FAFSA, and your dad will also sign your FAFSA with his FSA ID. Your dad will enter his info into your brother’s FAFSA and into your FAFSA, and you will complete your portion of your FAFSA. When it is complete, both you and your dad will sign it ith your FSA ID’s, and you will submit it.
