From the State Controller’s published file
California is holding 725 unclaimed property records under the surname Koo, worth $483,653 in total. Whether any of it is yours depends on the first name and the address, which is what the free search checks.
Search every Koo record free No account, no card. Most people find nothing — the check costs nothing either.
The city is the last address the reporting company had, which is usually where the person lived when the account went quiet — not necessarily where they live now.

These are the companies that handed the money to the State after they could no longer reach the owner. Recognising one is a strong hint that a record is yours.
Records are keyed exactly as the company typed them decades ago. If yours is not here, try a middle name, an initial, or a former surname — that is the single most common reason a search comes back empty.

43 of these Koo records are worth $2,500 or more, which is the point at which paying someone ten per cent to handle it starts to make sense. Below that, file it yourself — it is free, and we will show you how.

Ask me anything about California unclaimed property — how claiming works, what the State requires, what we charge, or whether a name turns up anything. I can run the real search.
I am not a lawyer and cannot say who is legally entitled to an inheritance. Our fee is capped at ten per cent by state law and nothing is owed until you have been paid.
