Actually…most colleges use only the FAFSA and will use just your custodial parent info…but make sure you know which parent that is. @kelsmom can explain
Some schools that use the CSS Profile also require the non-custodial parent form. That means financials from both parents must be provided. And some colleges have their own forms which do ask for non-custodial parent financials.
Lastly…if your parents are divorced, the NPCs might not be accurate…so view with caution.
