<p>I just looked at a book we have called "Paying for College without Going Broke." According to that book, "a step parent who resides with the custodial parent will be treated by the aid formula as if he/she were the natural parent" The book goes on to explain that it does not matter if the stepparent has adopted the child or even if they just met. If they reside together, the stepparent's income and assests are considered as if they were the natuarl parent. And this is for FAFSA & Profile.</p>
