Can I file FAFSA without ex's income when he already submitted with his information?
I just found out my ex filed a FAFSA application for our son apparently using only his income (he makes about $110,000 while I earn around $37,000). My son lives with me full-time (I have primary physical custody), and I never signed anything related to the FAFSA. My ex didn't even tell me he was submitting it! I'm worried this will mess up my son's chances for financial aid since his father's income is so much higher. Can I still submit my own FAFSA application using just my information? Does primary physical custody matter for FAFSA purposes? My son is heading to college this fall and I'm really stressed about financial aid!

the parent who provides more than 50% financial support is supposed to fill it out not just who they live with

•I provide at least 80% of his support! My ex just pays the minimum child support required by our state, and he's late half the time. Does this mean I should be filling out the FAFSA instead?

For the 2025-2026 FAFSA, the rules regarding divorced/separated parents have changed significantly. The parent who should complete the FAFSA is the one who provides more than 50% of the student's financial support, regardless of custody arrangements. This is different from previous years when it was based on which parent the student lived with most. Since your son lives with you full-time and it sounds like you provide the majority of his financial support, you should be the one completing the FAFSA. Your ex filing first isn't necessarily binding - you can submit a new FAFSA with the correct information. I recommend: 1. Gather documentation showing you provide the majority of support (receipts for housing, food, utilities, etc.) 2. Contact your son's school's financial aid office immediately 3. Submit a new FAFSA with your information 4. Be prepared to provide documentation that you're the appropriate contributing parent

•Thank you so much for this detailed information! I'll gather all my receipts and bank statements today. Do you know if I need to do anything special when I submit the new FAFSA to indicate that I'm correcting an error from my ex's submission?

I'd be FURIOUS if my ex did this behind my back! The system is so broken - they don't verify who should actually be filling these forms out until AFTER everything gets messed up. My daughter lost a $7,000 grant because her dad filled out the FAFSA without telling me, and he makes way more than I do. The financial aid office was absolutely USELESS in fixing it. Took me WEEKS of calling to get it sorted. The whole system is designed to make us fail!!

•I'm definitely angry about it. Did you have to keep calling the school's financial aid office or did you have to contact the Federal Student Aid office directly? I'm worried about how long this might take to resolve.

•BOTH! The school kept saying it was a federal issue and the feds kept saying talk to the school. Total runaround. Document EVERYTHING and be prepared to fight. Good luck - the system is STACKED against us single parents!!

I just went through this exact situation last year with my daughter and ex-husband. You need to call the Federal Student Aid helpline immediately, but be prepared to wait forever. I tried for 3 weeks and could never get through - calls kept disconnecting after being on hold for 2+ hours. I finally used Claimyr (claimyr.com) to hold my place in line and call me back when an agent was available. Totally worth it since I finally got through to someone who could help. They have a video showing how it works: https://youtu.be/TbC8dZQWYNQ Once I got through, I explained that my ex had inappropriately filed the FAFSA claiming he provided primary support when he doesn't. The agent created a case for me and guided me through submitting a correction. My daughter's corrected SAI score made her eligible for way more aid than she would have received based on my ex's income.

•Thank you for sharing this! I've been dreading the phone calls because I've heard how hard it is to get through. I'll definitely check out that service if I can't get through on my own after a few tries. How long did the correction process take once you were able to talk to someone?

•It took about 3 weeks for the correction to process once I spoke with an agent. The important thing was that they put a note in the system right away so the schools could see there was a pending correction. Make sure you explain the urgency if your son needs financial aid packages soon for decision-making!

When my ex did this I had to get a letter from our divorce lawyer stating I was the custodial parent who provides primary support. The schools financial aid office needed it along with the FAFSA correction.

•That's really helpful to know. I think I still have contact info for the lawyer who handled our divorce. I'll reach out to get something in writing. Thank you!

I don't understand why the FAFSA is so complicated with divorced parents anyway like why can't they just look at BOTH incomes and figure it out themselves?? My parents divorced when I was applying for college and it was a NIGHTMARE trying to figure out which one should fill it out and then my dad's new wife's income had to be included which made no sense since she doesn't even help support me at all!!

•The 2025-2026 FAFSA actually made some significant changes to how they handle divorced parents. Now it's supposed to be based on which parent provides more than 50% of financial support rather than who the student lives with. They're trying to make it more fair, but it definitely creates confusion during the transition period.

One important update: Once you submit your corrected FAFSA, contact each college's financial aid office directly. Let them know about the situation and that you've submitted a correction. Many schools have a special form for FAFSA corrections or professional judgment reviews for exactly this scenario. Also, make sure your son selects you as the contributing parent when he signs into his FAFSA account. The student has to confirm which parent they consider their contributing parent.

•I didn't realize my son will need to confirm me as the contributing parent. He doesn't have a FAFSA account set up yet (at least not that I know of). Does that mean my ex had to create one for him to submit the initial FAFSA? Should I have my son check if he already has an account?

•Yes, for a parent to submit a FAFSA, the student needs to have a Federal Student Aid ID (FSA ID). I'd have your son check if he already has one - if he does, he should log in and check what's been submitted. If his father created one without his knowledge, that's problematic and you should definitely report that when you call Federal Student Aid.

when does ur son start college? u might need to hurry this up if its soon cuz financial aid gets given out first come first serve

•He starts this August - about 5 months from now. I'm definitely going to try to get this resolved ASAP. I had no idea that financial aid was first come, first served! That makes this even more urgent.

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!

•That's good to know! He's applied for a few local scholarships. I didn't realize they could affect the need-based aid calculations. This process is so complicated.

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!
