Every state runs a free official unclaimed-property search, and every legitimate claim is free to file. The catch is knowing which office holds it: usually the State Treasurer, but not always — and a national aggregator that several big states never joined.

How the States Differ
Custodians vary more than people expect: most states park unclaimed property with the Treasurer or Comptroller, but Indiana hands it to the Attorney General, Arkansas to the Auditor, and North Dakota to the Department of Trust Lands. The state guide names the right office so you don't chase the wrong one.
MissingMoney.com, the NAUPA-endorsed multi-state search, is genuinely useful — but California and New York, the two biggest pools of unclaimed money in the country, are not fully on it. Searching those states directly is mandatory, and searching every state you've ever lived in is the move that actually finds money.
