<p>For FAFSA purposes, your custodial parent is the parent you've lived with most during the past 12 months. If your parents are separated on the day you file the FAFSA, check the bos for Divorced/Separated regarding parent's marital status. Doesn't have to be a court sanctioned separation or a separation with a legal agreement.</p>
<p>The non-custodial parent's income won't be included in the FAFSA. Profile is another matter.</p>
