State Unclaimed Property in Illinois

The Illinois State Treasurer holds unclaimed property — dormant bank accounts, uncashed checks, insurance proceeds, and similar assets — under the Revised Uniform Unclaimed Property Act until the owner or their heirs claim it. Heirs of a deceased owner file a claim through the I-Cash portal with proof of death and authority to act for the estate.

Steps to take when someone dies

  • •A death certificate for the listed owner, and proof that the deceased owned the asset
  • •Court-certified Letters of Office (dated within the last three years) if probate is open, or a small estate affidavit listing all heirs if the estate was not probated
  • •Proof of the claimant's relationship to the decedent through death, birth, and/or marriage records

Documents for an heir or estate claim

An heir claim needs a claim form, notarized if the claim is over $5,000 or involves a safe deposit box or securities, the death certificate of the listed owner, and proof that the deceased owned the asset. The added documents depend on the estate: no will, a will filed but no probate, an open estate, or a closed one.2

A Capacity to Claim Affidavit with proof of death may be used instead only when the total claimed value is $250 or less.2

Deadline to claim

There is no deadline. The Treasurer holds unclaimed property in a custodial capacity until the rightful owner or heir claims it.3

Claiming without a probate order

Section 25-1 of the Probate Act allows an Illinois Small Estate Affidavit in place of Letters of Office when no letters of office are outstanding, contemplated, or pending and the personal estate, excluding motor vehicles registered with the Secretary of State, does not exceed $150,000.4

The Treasurer publishes its own small estate affidavit form and accepts it on heir claims where there is no will or a will was filed but not probated.5, 2

Processing time

Claims are reviewed in the order received. Processing time before a claimant receives a first communication or payment may be up to 12 weeks, depending on the number of claims submitted.3
