An Illinois Small Estate Affidavit allows heirs to collect assets from a deceased person's estate without probate under 755 ILCS 5/25-1. The statewide threshold is $150,000 after the August 2025 amendment. Cook County has a separate, lower formula: $20,000 base plus $10,000 per surviving minor child.
Illinois Small Estate Affidavit: 2025 Law Change, Cook County Rules, and How to File
Small Estate Affidavit — Illinois, standard
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.
What Changed in August 2025 — and Why It Matters
The Illinois Probate Act's small estate provision (755 ILCS 5/25-1) was amended in August 2025, raising the statewide threshold and updating certain procedural requirements.
The practical effect: Many families who previously had no choice but to open a formal probate estate — a process that can cost $3,000–$15,000+ in attorney fees and take 9–18 months — can now use a small estate affidavit instead. If a guide, form, or tool you've found reflects the old law: stop and use current materials.
The Two Different Illinois Thresholds
Statewide: $150,000
Applies to all Illinois counties except Cook County. Total gross assets of $150,000 or less (as amended August 2025).
Cook County: Different Formula
$20,000 base + $10,000 per surviving minor child
Who Can Use an Illinois Small Estate Affidavit?
Under 755 ILCS 5/25-1, the following people may present a Small Estate Affidavit:
- An heir of the deceased (as defined by Illinois intestate succession law)
- A legatee (someone named in a will)
- A creditor of the estate (to collect amounts owed)
What Assets Qualify?
Included in the $150,000 cap
- Bank and savings accounts (without POD designations)
- Checking accounts
- Certificates of deposit
- Personal property, household goods, jewelry
- Vehicles (Secretary of State has separate process)
Generally pass outside the affidavit
- Life insurance with named beneficiaries
- Retirement accounts (IRA, 401(k)) with beneficiaries
- Payable-on-death (POD) bank accounts
- Joint tenancy property
- Real estate in Illinois
Common Mistakes
- Using the wrong threshold. Applying the $150,000 statewide limit to a Cook County estate when the actual limit may be far lower is a common and costly error.
- Counting non-probate assets. Life insurance proceeds with named beneficiaries, POD accounts, and 401(k)s do not count toward the $150,000 threshold. Families often assume the estate is over the limit when it is not.
- Not waiting 30 days. An affidavit presented before the 30-day period is legally defective.
- Assuming real estate is covered. Unlike Arizona, Illinois's Small Estate Affidavit generally does not cover real property transfers.
- Using pre-2025 forms. The August 2025 amendment changed both the threshold and certain procedural elements. A form from before that date may be outdated.
What Banks Actually Do with the Affidavit
Community banks and credit unions
Generally more cooperative. Often accept a properly prepared affidavit with a death certificate and will release funds promptly.
Large national banks (Chase, BofA, Wells Fargo)
May have their own internal affidavit forms and may require a branch manager's approval for amounts above $5,000–$10,000. Legally authorized to honor the affidavit, but individual employees may be unfamiliar with the law.
Most effective approach: Present the affidavit with a bank instruction letter that cites 755 ILCS 5/25-1 and explains the bank's legal authority to release funds. This is included with every smallestateform.com document.
