Top Law Schools

If I used FAFSA for undergrad, do I need to start a new FAFSA for law school or can I just renew my FAFSA?

Thanks for the replies, I am recently just trying to scrounge up money and figure out my finances before March 1st. Thanks alot everyone.

You can use your old account number but you need to refill and resubmit your personal information every year.
