Illinois Financial Affidavit - Checklist
Financial affidavits are a common pain point in Illinois family cases. This is an educational checklist to help you gather documents and avoid inconsistencies. Not legal advice.
What to gather
- Recent paystubs + tax returns (if available)
- Childcare and health insurance costs (if relevant)
- Monthly bills/statements to sanity-check expenses
- Asset/debt balances (approximate is better than blank)
Common mistakes
- Totals that don’t match paystubs/tax records
- Guessing expenses without a consistent method
- Leaving assets/debts blank instead of “unknown/approx”
- Not checking county-specific filing requirements
