DownloadSmall Estate Affidavit — Illinois, Cook
A Small Estate Affidavit allows heirs to collect and transfer assets from a deceased person's estate without going through full probate court — as long as the total estate value is within the state limit.
Statutory authority: 755 ILCS 5/25-1 (amended August 2025)
Real-World Example: The Nguyen Family, Evanston, Cook County
The Nguyen family's mother died in Evanston, leaving a Chase Bank savings account with a balance of $28,000. She had no real property. Total qualifying estate value: $28,000 — well under the $150,000 statewide threshold.
What they did:
- Waited 30 days from the date of death (the statutory minimum under 755 ILCS 5/25-1).
- Ordered four certified death certificates from the Cook County Clerk's Vital Records division ($19 each).
- Filed the original affidavit and a certified death certificate at the Daley Center Probate Division, Room 1202. Filing fee: $62.
- Presented a file-stamped certified copy of the affidavit and a certified death certificate to Chase Bank's estate services department.
- Received the account balance distributed equally to the three heirs approximately six weeks after the initial filing.
Total time from death to distribution: approximately nine weeks. No probate opened. No attorney required.
Should You Use the Small Estate Affidavit? Decision Framework
| Your Situation | Best Path |
|---|---|
| Financial accounts only, total under $150,000, 30+ days since death | Small Estate Affidavit — present directly to the bank, no court filing needed |
| Financial accounts, need court documentation, under Cook County formula | Cook County SEA filing at Daley Center Room 1202 |
| Estate includes real property in Illinois | Probate required for real estate — SEA handles personal property only |
| Total estate value exceeds $150,000 | Formal probate — SEA threshold not met |
| Accounts have named POD/TOD beneficiaries | No affidavit needed — those accounts pass directly to beneficiaries |
| Death occurred fewer than 30 days ago | Wait — the 30-day statutory period cannot be waived |
The Two Illinois Thresholds — Which One Applies to You
Statewide Threshold: $150,000
For bank-level affidavits presented directly to financial institutions. Applies across all Illinois counties including Cook. No court filing required if total qualifying estate is at or below $150,000 and 30-day waiting period has passed.
Cook County Court Formula
For court proceedings: $20,000 base + $10,000 per surviving minor child.
- • No minor children: $20,000
- • One minor child: $30,000
- • Three minor children: $50,000
Important: Small Estate Affidavits Do NOT Transfer Real Estate in Illinois.
An Illinois small estate affidavit does not transfer real property, regardless of its value. If the estate includes a house or condo in Cook County, formal probate is required for that real estate. The small estate affidavit can still handle financial accounts; the real estate is handled separately.

Common Mistakes That Get This Document Rejected
❌ Filing before 30 days have passed since death. The 30-day waiting period is a hard statutory requirement. No bank, court, or institution can waive it. Filing on day 29 means the affidavit will be returned.
❌ Using a statewide form when Cook County clerks expect their local format. A bare-bones affidavit that satisfies the statute's minimum text but omits structural elements the local clerks expect may be returned for correction. Use a form built specifically for Illinois, not a generic multi-state template.
❌ Attempting to use the affidavit to claim real property. Illinois's small estate affidavit does not transfer real estate under any circumstances. Including a house or condo in the affidavit is a legally defective document.
❌ Bringing a photocopy of the death certificate instead of a certified copy. The Daley Center Probate Division requires a certified death certificate with the county seal or state vital statistics embossed stamp.
❌ Going to the wrong room at the Daley Center. The Probate Division is in Room 1202. Other civil and county clerk functions are in different rooms. The main clerk windows on the ground floor do not handle probate filings.

Cook County-Specific Tips
Order more death certificates than you think you need. The Cook County Clerk's Vital Records division issues certified death certificates at approximately $19 per certified copy (2025–2026). Order at least 4–6 copies: one for the court, one for each financial institution, one for any pension or retirement benefit, and one to keep.
The Daley Center can be slow on certain days. Monday mornings and the days after holidays see the longest wait times at the Probate Division counter. Arrive by 8:30 a.m. or aim for Tuesday through Thursday for shorter waits. January and September are peak months — 2–3 week processing backlogs are common.
Some Cook County bank branches require a court-certified copy. Larger national bank branches in the Loop may require a court seal on the affidavit copy. A court-certified copy (obtained by filing the affidavit at the court first) carries an official court stamp that satisfies this requirement.
If a bank resists, cite the statute. Illinois law (755 ILCS 5/25-1) expressly provides that a properly executed small estate affidavit is sufficient evidence for any person owing money or property to the deceased. The institution has a legal obligation to honor it if the requirements are met.
