Illinois unclaimed property: what to know
Updated
Coming soon. We currently file claims in California only. We are not offering Illinois claims yet.
Illinois's unclaimed property program is run by the state; its search is at icash.illinoistreasurer.gov. If you use a finder (a paid recovery service), these rules apply.
Finder rules in Illinois
- A finder agreement is void if made within 24 months after the property was delivered to the Treasurer.
- Fees are capped at 10%.
- Finders need a licence from January 1, 2026; a finder is paid directly only if the agreement provides for it.
How this compares with California
In California an investigator may charge up to 10%, only after the Controller pays, and may sign an agreement as soon as the Controller holds the property. The Controller pays the investigator's share directly.
