Discovery Post-Judgment

Post-judgment discovery is not permitted without a motion hearing scheduled before the court.  If your name is listed on the account then you should be able to obtain statements directly. During the divorce, discovery requests are available with subpoena forms or a Request to Produce to the opposing party pursuant to the court rules:
