When parents are divorced...the only parent information on the FAFSA is for the custodial parent (the parent you reside with) and their spouse (if there is one).
If the student lives with both parents an EQUAL amount of the time, the parent (and spouse) reported on the FAFSA is the one with the HIGHER income.
Now...for the Profile, if needed...EVERYONE's income is reported (both parents and spouses if any).
