"Reverse engineering can be done without access to the other parent’s financial documentation.
For example, if one parent know his/her own finances and the student’s financial aid package, it should not be difficult to make a reasonable guess at the other parent’s finances by putting in the one parent’s known finances and guesses of the other parent’s finances in the college’s net price calculator until the one parent finds a guess that produces a net price calculator result similar to the student’s financial aid package."
Fortunately for all, none of that is possible in Profile. Once the student answers -at the very beginning of the Profile- that the parents are divorced, Profile will then only provide input fields for the custodial parent (CP) household. There’s nowhere for the CP to input reasonable guesses about the NCP: no data-entry fields will appear; no questions about NCP household finances, etc., will be asked. There’s simply nowhere for the CP to enter data or info for the NCP -not at the time when completing the Profile, nor any time after.
