Ex-wife is custodial parent and it appears she is committing FAFSA fraud by hiding assets

Thanks for all the input. My ex makes a little over $62K. I don’t know all the facts like some have mentioned. So I don’t know if it was really fraud or not. And like I said, I “had” thought about reporting her previously but have no plans to do that and was interested in what could happen if she has committed fraud and got caught and what impact that could have on my daughter.
