Can I take my ex to Court and sue him for my share of the tax return refunds?

While my husband and I were going through divorce proceedings, he filed 2 years of federal and state tax returns as "Married, Filing Jointly" and used mine and our children's social security numbers (one year without my knowledge or permission). He had all of the Refunds deposited into his personal bank account and did not give me my full share of the Refunds. He has refused to give me copies of the two years of Income Tax Forms or proof of payment of my 50% share to me. Which Court would I file papers with? Thanks in advance!
