Cook County · six questions

Some states file with the county court; others never go to court — the affidavit goes straight to the bank or DMV. The county decides the office and the fee.

3 · Was there a will?

Bank accounts, vehicles, final paychecks, personal property. Leave out joint accounts, accounts with a named beneficiary, and life insurance — those pass without probate anyway.

5 · Did they own real estate other than the home they lived in?

Most states make you wait 10–45 days before the affidavit can be signed or filed.

Has anyone already opened a probate case?

Cook County procedure

  1. Certified death certificates from Illinois vital records or the county registrar — five or more.
  2. Inventory everything in the person's sole name; stop if the total is over $150,000.
  3. Gather the paperwork — death certificate, asset list, and the will if there is one.
  4. Complete the Illinois form — Notarized; the affiant takes on personal liability for the decedent's debts up to the value collected, and must pay known creditors before distributing.
  5. Present it to each holder — $0; will filing free. Bring a certified death certificate for each.
  6. Collect, pay debts, distribute — keep every receipt; the affiant is liable up to the amount collected.

What makes Illinois different

Illinois has no waiting period — you can use the affidavit as soon as you have the certified death certificate — but the trade-off is liability: the person who signs is personally responsible for paying the decedent's debts out of what they collect, and for distributing correctly.

The affidavit must list every debt and every heir with their shares under the Probate Act. Leaving a creditor off is the classic mistake; funeral expenses are paid first.
