Since your question is about the upcoming 2025-2026 school year, I want to clarify: The FAFSA now uses the concept of "contributors" rather than "custodial/non-custodial" terminology. For divorced parents, generally the parent who provided more financial support and with whom the student lived more during the preceding 12 months will be the contributor who completes the FAFSA. Based on your 90% custody situation, that's clearly you. Make sure to use your 2023 tax information when completing the 2025-2026 FAFSA, and report any child support received during that tax year. Then, as others have mentioned, contact each school's financial aid office to explain that the child support has ended, which constitutes a significant change in circumstances that may qualify for a professional judgment review.

I'm going through something similar right now! My ex makes way more than me but I have primary custody. What really helped me was keeping detailed records of everything - custody schedules, who pays for what expenses, etc. Also, don't forget that even though child support is ending for your oldest, if you're still receiving it for your other three kids, that will still count as income on the FAFSA. But the good news is that as the custodial parent with 90% custody, you're definitely the one who should fill it out, and your son should qualify for aid based on your income level. The system actually works in your favor in this case, unlike some of the horror stories here about remarriage situations!

After you get this resolved, make sure your son updates his FAFSA if there are any other scholarships or outside funding he receives. My daughter got a $3,500 merit scholarship after we submitted her FAFSA, and we had to update the form or it would have reduced her need-based aid. These forms are so sensitive to every detail!

I'm so sorry you're dealing with this situation - it must be incredibly frustrating to have your ex file without your knowledge! As someone who's been through the FAFSA process, I can tell you that you absolutely need to act quickly. The fact that you have primary custody AND provide 80% of your son's support means you should definitely be the one filing the FAFSA, not your ex. Here's what I'd recommend doing immediately: 1. Have your son check if he has an FSA ID account (your ex would have needed to create one for him) 2. Start gathering all your financial documents and proof that you provide the majority of support 3. Call the Federal Student Aid helpline as soon as possible (though be prepared for long wait times) 4. Contact each college your son applied to and let them know about the situation Don't let this delay your son's college plans - schools deal with these correction situations more often than you might think. The key is being proactive and having documentation ready. Your son's financial aid eligibility could be significantly better with your lower income, so this correction is definitely worth pursuing!

btw my sister ended up getting WAY more aid after they finally processed her updated info without her husband's income. they recalculated her SAI and she got the full Pell Grant plus extra institutional aid. so don't give up!!

I'm so sorry for your loss, and I want to echo what others have said about documenting everything and being persistent. One thing I'd add that I haven't seen mentioned yet - when you contact the financial aid offices, ask specifically about "dependency override" in addition to the professional judgment review. Since your husband was the primary income earner and you're now supporting your son alone, this could potentially qualify you for additional aid considerations. Also, some schools have emergency aid funds specifically for situations like yours, so it's worth asking about those as well. The process can be overwhelming, but you're advocating for your son's education and that's incredibly important. Stay strong and don't hesitate to ask for help from the financial aid counselors - that's what they're there for.

Thank you everyone for the incredibly helpful advice! I've talked with my cousin and we're going to: 1) Gather all the documentation about her mom's death and dad's work situation, 2) Contact each school's financial aid office directly to explain the situation before submitting the FAFSA, and 3) Look into those special circumstances forms that several of you mentioned. Also going to try that Claimyr service to speak directly with an FSA agent since we've had no luck getting through on our own. I'll update here if we find a solution that might help others in similar situations!

I went through something very similar with my younger sister a few years ago. Her biological dad passed away when she was 16, and our mom remarried. The stepdad was financially well-off but made it clear he wasn't paying for college. What saved us was being proactive with the schools she applied to. Here's what worked: We called each financial aid office in early fall (way before FAFSA deadlines) and explained the situation. Most schools have seen this before and have specific procedures. Three out of four schools she applied to were able to work with us through their "professional judgment" process. The key was having documentation ready - death certificate, proof of the stepdad's refusal in writing (we had him sign a simple statement), and letters from us explaining the family dynamics. One school even told us they could treat it as if mom was unmarried for financial aid purposes once they reviewed everything. Your cousin shouldn't give up - the system has more flexibility than it appears on the surface, but you have to know how to navigate it. Start making those calls to financial aid offices now!

UPDATE: First, thank you all SO MUCH for the helpful suggestions! I finally got through to FSA after using that Claimyr service someone recommended (it actually worked!). The agent confirmed it was exactly what @profile2 suggested - the marriage date in December 2023 was causing a flag since we filed jointly that year. They helped me submit a correction with a special note explaining the situation, and the agent said they'd expedite the review since my daughter's aid deadline is coming up. The status now shows "Correction Processing" so fingers crossed it will be fixed in a few days. Will update when we know for sure!

Wow, this thread is incredibly helpful! I'm a high school counselor and I've had several families dealing with this exact same issue this year. The 2025-2026 FAFSA rollout has been especially buggy with these hidden validation errors. I'm definitely going to share the Claimyr service with my families - the FSA phone lines have been completely overwhelmed this season. It's so frustrating that the system shows "processed successfully" when there are actually blocking issues. Thank you everyone for sharing your solutions - I'm going to create a checklist for my families based on all the common causes mentioned here (marriage date discrepancies, household size vs tax dependents, hyphenated names, incomplete contributor sections, etc.).
