Thanks for asking your question! I'm sorry to hear about your tax
issue and I'm going to try my best to help you understand or resolve it.
Thank you for your question, and thanks for using JustAnswer.com. In order to see if your ex husband has not claimed the children you would attempt to e-file your return
. If your ex husband claimed the children then your return will reject as the IRS
will already have a record of your dependent
being claimed on a return. If your return goes through, then the children have not been claimed.
Thanks again for using JustAnswer.com and have a great day.

You should be aware that your question, as with most tax questions, can never really be answered completely...addressing all the permutations; that is because of the many assumptions that have to be made I have done my best to determine what I think you are asking and answering it in the most direct and understandable manner possible. If, however, after reviewing the questions, you have any uncertainties or further questions, please do not hesitate to ask.
