Dear Liz: My ex-wife and I are about to start the financial aid process for our eldest child, who goes to college in the fall. My ex happens to have a higher income than me, and has asked me if I’d be willing to have different aid scenarios calculated based on our different incomes and assets. From all the research I’ve done, though, it seems she is the one who needs to file the Free Application for Federal Student Aid, since she’s the custodial parent. It’s not possible to choose who the custodial parent is for the purposes of financial aid, right?
Answer: It may be possible, but you have to make the choice well before you file the FAFSA form.
For federal financial aid purposes, the custodial parent whose information is used to calculate financial need is the parent with whom the child lived the most during the 12 months before the FAFSA is filed. With joint custody, the custodial parent is typically the one who provided the most cash support.
Some divorced parents opt to revise their children’s living arrangements so that the lower earner becomes the custodial parent. That may require a trip to court to revise a custody agreement. Also, the financial situation of any stepparents would have to be part of the equation, since the income and assets of the custodial parent’s spouse (the stepparent) are factored into the federal formula.
