So I finalized my divorce in December of 2019. Per the court agreement we are to file married jointly and claim both of our children together but I am to receive all income tax between the two of us. (ex husband and I). We both filed and completed it and signed to finish filing the taxes and now my ex husband is trying to amend the taxes to try and claim one of our children. The current income tax we did married jointly was already received by the IRS and is currently in process. Is there anything I can do to fight against this? We finalized our divorce December 4th and he is arguing because we were not married 12/31/19 he can do it.
