Who can claim for someone who has died

Heirs and estate representatives can claim for a deceased owner. Because the state follows the Illinois Probate Act, you will be asked to establish your relationship to the owner.

What you will typically need

  • A completed and signed claim form
  • A death certificate for the owner
  • Documents establishing your relationship to the owner or your authority as the estate’s representative
  • Photo identification

Requirements can vary with the type and amount of property. Follow the instructions on the official site.

What it costs

Free. The Treasurer returns property at no cost with proper identification.

Good to know

  • There is no deadline to claim. The Treasurer holds unclaimed property in a custodial capacity until the owner or an heir successfully claims it.
  • Claim documents can be uploaded through the I-CASH site, emailed to the Treasurer’s unclaimed property office, or mailed.

Search other states too

Property is reported to the state where the company is located, so check every state your loved one lived in. MissingMoney.com searches most participating states at once. You can also browse every state and DC in our unclaimed property guide.

Make sure your family never has to search

The Only Step gives your family a clear list of where to look, so no account is left to be discovered by chance.
