FAFSA - - Ex-Spouse Pushing to Have My Infomation On Form Instead of His - Fishy?

[BelknapPoint]

Well, if you’re rather certain that Household 2 doesn’t have a lot of assets, you probably could estimate that IF the school determined that an $80k income should pay $10k, then it might be safe to estimate that Household 2’s income is around $110-130k if they’re expected to pay $25k.

My ex in Household 2 has remarried, and I have no idea what kind of assets they may have. So how can I use that expected contribution of $25k to estimate assets and income for Household 2?
