@matigo If she could have actually been an adult and file taxes the way we'd done the last 25 years, we would have done a joint return for 2021 and gotten a refund. Instead, she chose to violate a court order and filed a separate return…and got a refund.
I got her tax return through discovery and see she claimed things she had no right to claim considering I made all the income in 2021. The tax return I filed based on that is practically guaranteed to cause an audit for both of us even though I ended up owing money. And, unfortunately for her, the facts are on my side.
