You are required to complete a financial affidavit which is a form where you disclose your income, monthly expenses, assets, and your liabilities filing for divorce. This form tells all parties involved in the divorce of the assets and liabilities that each spouse has and what is shared between the couples. If you think that your spouse is not listing all of their accounts and liabilities reasonably on this form, you should seek a subpoena with the help of your divorce lawyer in Chicago IL.
