You are incorrect. Yes,students can file a FAFSA without oarent information IF the parents agree that they are providing NO support to the student, and won’t be claiming the student on their taxes. BUT all this will get the student is the Direct Loan. And really…the student would get that anyway!
If you are talking about possibly getting a dependency override, I seriously doubt this student would get this. “My parents won’t pay my college bills” is not a sufficient reason for being granted a dependency override.
