Illinois Financial Affidavits and Disclosure

FamilyCourtHelp is an independent educational platform. It is not a court, law firm, government agency, or government partner. We organize and link to publicly available resources published by courts and government agencies. Official requirements may change. Always confirm current requirements with the applicable court or clerk.

Any Illinois family case about money runs on financial disclosure. Both sides put their income, expenses, assets, and debts on an official form, and courts generally expect supporting paperwork such as tax returns, pay records, and account statements.

Getting this right matters more than most parents expect. A judge who cannot trust your numbers will not trust the rest of your case either. The official Illinois affidavit sources and the court rules that define the exchange are linked below.

Frequently asked questions

What happens if I leave something off the affidavit?

An incomplete or inaccurate financial affidavit can be challenged, and it can cost you credibility with the judge for the rest of the case. If you are unsure about a number, say so on the form rather than guessing silently.

What if the other side will not disclose?

You can normally ask the court to order it, and courts can impose consequences for refusing. Keep your own disclosure complete and on time either way.

Are these documents public?

Rules on sealing financial documents vary by state and by court. Check the official Illinois rules linked above, or ask the clerk, before you assume the filing is private.
