California unclaimed property: a guide for business owners

Updated November 8, 2026

California unclaimed property is money and other financial property that a company, bank or insurer owed someone but could not deliver. After the holder loses contact with the owner, it reports the property to the California State Controller, which holds it until the owner claims it. Businesses are owners too, and often for large amounts.

How property reaches the Controller

Every holder that owes money it cannot deliver, such as a bank with a dormant account, a customer that owes you a credit, or an insurer with a refund, must eventually report it to the Controller with the owner's name and last known address. The Controller's public file lists each record with the property type, the amount and the company that reported it.

How much is held for businesses

In the Controller's file dated November 4, 2026, 20,456 business-type owners with California addresses each have $10,000 or more in open records, $691.4 million in total (our analysis). The biggest kinds of property held for them:

How a business proves its claim

The Controller needs to see that the business is the owner on the record and that the person signing can act for it. Expect to provide the signer's photo ID, proof of authority, proof of the business's FEIN and proof the business was at the address on the record. Renamed, merged and dissolved companies also document the link from the old name to today's owner.

The rules every claim follows

• The claimant signs the Controller's claim form in wet ink. It is notarized when the cash property totals $1,000 or more, and for all securities claims.
• A power of attorney is not accepted in place of the claimant's signature, apart from narrow medical exceptions.
• New claim packages go by mail, courier or in person. They cannot be emailed or faxed.
• The Controller decides within 180 days of a complete package, first in, first out.

How payment works

The Controller pays approved claims by warrant. If an investigator filed the claim under a written agreement, the Controller mails the owner's share to the owner and the investigator's percentage to the investigator, separately.

What a recovery service may charge

California caps an investigator's fee at 10% of the property recovered and bars any fee before the Controller pays (Code of Civil Procedure section 1582). An agreement is allowed only once the Controller holds the property, and it must state the property's nature and value and that the Controller holds it.
