Frequently asked questions
Search the Missouri State Treasurer's free portal at treasurer.mo.gov/UnclaimedProperty, then file a claim with proof of death and proof of authority — a certified copy of Letters Testamentary or of Administration if the estate was probated, or the Treasurer's Table of Heirship if it was not.
No. The Missouri State Treasurer never charges to return unclaimed property. Beware of third parties who offer to recover it for a fee.
Missouri holds unclaimed property under the Uniform Disposition of Unclaimed Property Act until it is claimed, so there is generally no deadline for heirs to file a claim.
If the total estate does not exceed $40,000 (net of liens, debt, and encumbrances) and at least 30 days have passed since death, heirs may use the RSMo 473.097 small estate affidavit filed with the probate division of the circuit court, avoiding full administration. For a deceased owner, Missouri administrative rule 15 CSR 50-3.090 accepts a certified copy of the letters testamentary, a refusal of letters, or the probate court's final order of distribution, together with a death certificate, as authority to process an unclaimed property claim.
