The Missouri State Treasurer's office runs the programme and gives it a name that explains it, Missouri's largest lost and found. Each year financial institutions, businesses, government agencies and other organisations hand over millions of dollars in cash and the contents of safe deposit boxes, and the about page explains what triggers that transfer, which is five years with no documented transaction and no contact with the owner. What counts is cash from bank accounts, stocks and bonds, the contents of boxes, uncollected insurance policy proceeds, government refunds, utility deposits and wages from past jobs; what does not is real property, so land, houses, cars and boats are no part of this programme.
The size of the fund depends on the page. The search portal says the office currently holds more than $1.5 billion in unclaimed assets, while the about page says the Treasurer holds $1 billion for Missouri in more than 5 million owner accounts; both were read on the same day and both are the Treasurer's own. The figures that matter to a searcher are the other two, that one in ten Missourians has unclaimed property and that the average return is about $300, and the office states that it never charges to give property back. Claim post goes to the Office of the Missouri State Treasurer, Unclaimed Property, P.O. Box 1004, Jefferson City, MO 65102, holder reports to a different box, and the office is open from 8 a.m. to 4.30 p.m. on weekdays. For Missouri records held locally, see the Missouri county pages.
- Interest: where the property was reported as an interest bearing account, the Treasurer pays the owner up to seven years of interest on the cash.
- No deadline: cash property is held in trust forever and the office states there is no time limit for filing a claim.
- Paperless: more than half of all individuals with property can file a claim online with no documents to post.
- Medals: since August 28, 2010 no military medal or honour held by the programme may be auctioned or sold.

Searching, and the claim most people never post
The search portal offers three ways in, a person search, a business search and a search by property identifier, and it works like a shopping basket, with found properties added to a claims cart and the claim built from them in four steps. The questions page gives the most useful fact about what follows: more than 50 percent of all individuals with unclaimed property can file a paperless claim, meaning the system verifies them without documents.
Everyone else, and anyone who prefers paper, can write to the Jefferson City box with a list of owner names, addresses and previous addresses, and the office will say whether any of those names match property in its custody and send a claim form with instructions on the documentation needed. Only the original owner or, where the owner has died, a legal heir can recover the property. A claim already filed is tracked with the claimant's postcode and the claim identifier, or through a claimant account that shows every claim at once.
The interest nobody expects
Most states return exactly what was reported. Missouri does not always. The questions page answers the question of how long an owner has by saying there is no time limit, that the Treasurer maintains unclaimed property in trust for the rightful owners forever, and then adds a sentence worth reading twice: if the property was reported to the Treasurer as an interest bearing account, the Treasurer pays the owner up to seven years interest on the cash property.
For an old savings account or certificate of deposit handed over years ago, that is a materially larger payment than the reported balance, and it is paid without the owner asking for it. The office frames the whole service as a public one provided at no cost, and says its aim is to avoid unnecessary delays in documentation and payment rather than to put obstacles in the way.
Medals, heirlooms and the auction
Safe deposit boxes arrive with more than money in them. The about page describes family heirlooms, jewellery and keepsakes, and singles out military medals and insignia as among the most precious items recovered, with the Treasurer and his team working to return them to the people who earned them or to their families; the names and last known addresses of the box owners whose boxes held medals are published so relatives can look for them.
The protection behind that effort is in the questions page: as of August 28, 2010, no military medal or honour held by the programme will be auctioned or sold. Other non monetary assets of value are a different matter, and the office is occasionally required by law to sell them. The auction terms are set by section 447.558 of the Revised Statutes, which provides for sale to the highest bidder at public auction, and they are strict in both directions: items sell by lot and nothing may be separated from a packet, the contents are sold as they are and where they are with no warranty from the Treasurer, the State or the auctioneer and no guarantee of dates, markings, item counts or authenticity, and the buyer takes title free from all claims of the owner, any prior holder or their successors.
What the owner keeps is the money, because the proceeds are recorded in the owner's name so that they or their heirs can claim them, and those proceeds, like everything else here, are held until claimed.
Two things the Treasurer offers that other states do not
An owner who would rather the money went elsewhere can give it away through the office itself: unclaimed property can be donated to twenty different charitable organisations operating in Missouri, and in most cases the donation is completed entirely online. An owner who finds nothing today can be told when that changes, by signing up for email alerts that fire when new property arrives matching their information, which is the sensible response to a search that comes back empty.
Alongside those sit the annual newspaper advertisement lists for people who saw their name in the paper, a page for people who received a postcard, county totals showing what is held for each part of the state, and a separate search for unclaimed United States savings bonds.
What holders owe, and the dormancy table
The reporting page opens by telling businesses not to assume they are exempt, since it is rare for any organisation not to have unclaimed property, which arises from normal operations. It points to the usual sources: stale outstanding checks, where the underlying liability remains if the check never cleared and cannot be paid to the payee; liabilities written off to income or expense accounts, which must be reinstated and reported; other stale liabilities in the general ledger such as customer deposits and overpayments, accounts receivable overpayments, unidentified receipts and dividends payable; and securities held by agents, including uncashed dividend checks and shares left undelivered after splits and mergers.
Anyone doing business in Missouri or with Missourians must report, which reaches banks, credit unions, utilities, wholesalers, retailers, manufacturers, government entities, insurers, public corporations, public authorities, estates and trusts. The dormancy period is five years for everything except court bonds at one year, insurance demutualisations, rehabilitations and reorganisations and business dissolutions or liquidations at two years, payroll and the property of state agencies, political subdivisions and government entities at three years, money orders at seven years and traveller's checks at fifteen.
Where an owner is due $50 or more, due diligence comes first, meaning a letter to the last known or any newer address setting out the amount and asking for positive confirmation, or another reasonable means of contact. There is no minimum reportable amount, because the office has no authority to set one, although sums under $50 for a single owner may be reported in aggregate by property type, with the owner detail kept for at least five years after the dormancy period and encouraged to be reported anyway.
Records with owner level detail must be kept at least five years after reporting under RSMo 447.539.9, and twelve years for property with a seven year dormancy period. Where owner detail does not exist the amounts are reported as owner unknown, and where no records exist at all the amount is estimated using generally accepted accounting principles with the division's help. Shares and reports go together with pre approval, transferred electronically where possible and aggregated so each security moves as one lot, with only whole shares transferred and fractions liquidated and reported as cash in lieu.
Reports are filed through the online portal, and the dates are November 1 with a June 30 cutoff for all holders except life insurance companies, which file by May 1 with a December 31 cutoff.
Reading a Missouri result
A record here is listed under the name the company held, so a maiden name, a former business name and an address from three moves ago are each worth searching, and the free email alert covers the property that has not arrived yet. Nothing in the programme expires, so an entry from the 1990s is as claimable as one from last year, and if it was an interest bearing account the payment may be larger than the figure shown. If the record came from a safe deposit box that has already been sold, the claim is for the sale proceeds, and if the box held a medal, the medal itself is still in the Treasurer's keeping.
