7 Mistakes That Delay California Unclaimed Property Claims (2026)

Every week we see Californians try to file their own claims, only to have them stuck for months because of a small mistake on the paperwork. Here are the seven most common reasons claims get delayed — and how to avoid each one.

1. Using the wrong notary form

The State Controller's Office requires its own notarization wording on the claim affirmation. A generic notarized affidavit isn't always accepted. Use the SCO-provided form and make sure your notary fills in every field, including jurisdiction and commission expiration.

2. Submitting an expired or mismatched ID

If the name or address on your ID doesn't match the property record, the SCO will ask for additional proof. Renew your ID if it's about to expire, and have ready a utility bill or lease that bridges the gap between your current address and the address on the property record.

3. Missing address history

For older properties, the State Controller needs to see your address history connecting you to the property. Pull together old pay stubs, lease copies, tax filings, or utility bills from each address you lived at during the relevant period.

4. Incomplete estate documentation

Estate claims are the single most-delayed category because the documentation requirements are demanding. Don't file unless you have a certified death certificate, the will (if any), and either Letters Testamentary or a Small Estate Affidavit ready to go.

5. Filing one document at a time

Some people send what they have, then mail follow-ups as they gather more. Each new submission re-queues the file. File once with a complete packet.

6. Ignoring deficiency notices

If you receive a deficiency notice from the SCO, you have a limited time to respond before the claim is closed. Respond the same week — and respond in full, not in pieces.

7. Assuming a "claim ID" is enough

The Claim ID on a postcard or letter is just an identifier. You still need to fill in the full claim affirmation, supply ID and supporting documents, and notarize the affirmation.

How we avoid all seven

Every claim we file is reviewed against this checklist before it goes out. That, plus established communication with State Controller analysts, is why our claim approval rate is 98 percent — versus about half that for first-time DIY filers.
