Illinois executor and estate paperwork checklist

This is an organizer, not legal advice. An estate attorney or the county probate/surrogate office answers questions about your situation.

The first 30 days

Work down the list; nothing you tick is saved or sent. The steps are general, the dates come from the official pages.

1. Get several certified copies of the death certificateThe funeral home can usually order them, or the vital records office can. Each bank, insurer and pension plan may ask for its own.
2. Confirm the death was reported to Social SecurityUsually the funeral home does this. If it didn't, phone 1-800-772-1213 (TTY 1-800-325-0778); a widow or widower, or certain children, may qualify for $255.
3. Locate the signed will and any changesThe signed original matters more than a copy. Keep it whole and somewhere safe, and note who else has a copy.
4. Protect the propertyChange locks if keys are out, keep insurance paid, and have the mail forwarded so bills and statements reach you.
5. Pause before paying creditors or dividing keepsakesWho may act, and in what order bills get paid, depends on the route. Ask before you spend or distribute anything.
6. Stop using the person's power of attorneyA power of attorney ends at the principal's death, so an agent under it can't act for the estate.
7. Start an inventoryEvery account, property, vehicle and debt, with how each is held. Beneficiary and joint accounts usually pass directly, not through the estate.
8. Check the total against $150,000The official page's small estate figure (it changes with the date of death). Leave out anything the page says isn't counted.
9. Open a simple money logOne line per payment or deposit, with the date, who, how much and the receipt. It makes the final accounting easy.
10. When appointed, get an EIN and open an estate accountPay estate bills from that account only. Form 1041 is due if the estate has more than $600 of gross income in a year (IRS).
