My ex husband was supposed to claim our 2 children on his 2017 taxes, however, last year (2018) when it was time to file the 2017 taxes, he made it sound like he wasn't able too even though I did not claim them. However, when I asked him if he did or didn't claim them he would not answer me. My account says I can file an amendment to find out if he did claim them. It's been a year (now 2019), will I get the refund regardless or will the IRS reject it if he did claim them and will he he be notified if it I'm rejected?
