The Illinois Financial Affidavit (Family & Divorce Cases) is a document used in family and divorce cases in Illinois to provide an accurate and complete financial disclosure by each party. This document is used to provide information regarding each party's income, assets, liabilities, and other financial information. It is important that each party provides accurate information on the financial affidavit, as it can be used in determining spousal maintenance, child support, and other financial issues in the divorce proceedings. The three main types of Illinois Financial Affidavits (Family & Divorce Cases) are the Joint Financial Affidavit, the Simplified Financial Affidavit, and the Financial Affidavit for Spousal Maintenance. The Joint Financial Affidavit is a combined financial statement for both parties, and is used when both parties are in agreement about the financial disclosure. The Simplified Financial Affidavit is a simplified form of the Joint Financial Affidavit, and is used when only one party is providing financial information. The Financial Affidavit for Spousal Maintenance is used when one party is seeking spousal maintenance, and provides detailed information about each party's income, assets, liabilities, and other financial information.
