How to Fill Out the Claim Affirmation Form for California Unclaimed Property

To recover money or property held by the California State Controller, you file a Claim Affirmation Form generated through claimit.ca.gov, sign it (with notarization if the claim is $1,000 or more, or involves securities or a safe deposit box), and mail it in with proof of your identity and Social Security number. The California unclaimed property claim affirmation form is the document the Controller’s Office uses to confirm you are the rightful owner before releasing funds, and getting it right the first time is the difference between a check in 60 days and a package that comes back for corrections.

Start the Claim Online, Not with a Blank Form

Do not download a generic form or try to fill one out from scratch. Go to claimit.ca.gov, search your name or business name, and start a claim on the specific property record you find. The system generates a Claim Affirmation Form that is already pre-filled with your Claim ID and the property description in Sections A and B. That pre-population ties your paperwork to the correct record in the Controller’s system; a form built any other way will not match.

Write down the Claim ID as soon as it is issued. It appears on every piece of correspondence and is what you enter into the Claim Status Search later to track the file.¹

When You Actually Need the Paper Form

Some straightforward, lower-value claims can be finished entirely online as an e-claim. The site tells you at the end of the intake whether you qualify or whether a printed, signed Claim Affirmation Form is required. Paper filing is generally required for claims involving multiple owners, safe deposit box contents, securities, deceased owners, business entities, trusts, and higher-dollar amounts that automated verification cannot clear on its own.

Documents to Send with the Form

For a standard individual owner claim, plan to include:

A legible photocopy of a government-issued photo ID (California driver’s license, state ID card, or U.S. passport).
Proof of your Social Security number: a copy of your Social Security card, a W-2, or another official document showing the SSN. Businesses provide the Federal Employer Identification Number.
Your current mailing address, which is where the Controller sends the check.

The form itself instructs claimants to send as much documentation as possible if any required item is missing.² A partial package moves; a held package does not. Just expect a slower review if something is missing.

Filling In and Signing

Sections A and B come pre-filled. You complete Sections C and D, which cover verification and signature.² Read every printed field before signing. A mismatch between the name on the form and the name on your ID is one of the most common reasons claims are returned. If the property is listed under a maiden name, a former business name, or a slightly different spelling, include documentation that bridges the two names.

Your signature certifies, under penalty of perjury, that you are the rightful owner and entitled to receive the property. It also indemnifies the state against any loss resulting from paying the claim to you. If more than one claimant is listed, every claimant has to sign; a single missing signature sends the whole package back.

When Notarization Is Required

Get your signature notarized if any of these apply:³

The claim amount is $1,000 or more.
The claim involves securities, at any value.
The claim involves safe deposit box contents, at any value.

California caps notary fees at $15 per signature.⁴ Each signer must be notarized separately.

Joint Owners

If the property was held jointly, every listed owner must sign the form and submit their own identity documents.⁵ Start gathering signatures, IDs, and notarizations from co-owners early; coordinating across people is where these claims stall.

Filing for a Deceased Owner

When the owner has died, an heir, estate representative, guardian, or conservator files instead.⁶ Paper filing is always required, and you add:

A certified death certificate for the original owner.
Proof of your relationship or authority, such as letters testamentary, letters of administration, or a court order appointing you as executor or administrator.
A small estate affidavit under Probate Code Section 13100 if the total value of the deceased’s California personal property is below the statutory threshold and no probate was opened. For deaths on or after April 1, 2026, that threshold is $239,700.⁷
Your own photo ID and SSN proof, as with any claim.

Heir claims routinely take the full 180-day review. Send every relevant document in one package if you can. Supplemental documents mailed later restart the analyst’s review clock.

Safe Deposit Box Claims

The Controller will not disclose the specific contents of a box for security reasons, though you can ask whether the contents have commercial value.⁸ If the state has already liquidated the contents under the Unclaimed Property Law, you receive a cash payment. If the physical items still exist, they are returned to you after approval. All safe deposit box claims require notarized signatures regardless of value.

Where to Mail It

Send the completed form and all supporting documents to:⁹

Regular mail: Unclaimed Property Division, P.O. Box 942850, Sacramento, CA 94250-5873.
Overnight or in-person: Unclaimed Property Division, 10600 White Rock Road, Suite 141, Rancho Cordova, CA 95670.

Use a mailing method with tracking. A lost package means starting over, and the office takes roughly 60 days after receipt to enter a mailed claim into its system before review even begins.

After You Mail: Timing, Tracking, and No Interest

California law gives the Controller up to 180 days from receipt of a complete claim to decide it.⁶ Actual times vary:

Simple single-owner cash claims: 30 to 60 days.
Heir, multi-owner, or business-entity claims: generally the full 180 days.
Securities claims: an additional 120 days after approval for payment processing.

Check status any time at the Claim Status Search using your Claim ID, allowing about 60 days after mailing before your claim shows up in the system.¹⁹

Note one thing that surprises people: the state pays no interest. Section 1540(c) says you receive the amount originally reported to the Controller, regardless of how many years it has been held.⁶

If the Claim Is Denied

The Controller mails a written denial to the address on your form. You can sue in California superior court, and the deadlines are strict: 90 days from the denial, or, if the Controller has not acted within 180 days, 270 days from the date you originally submitted the claim.¹⁰

About Those Letters from Recovery Firms

If you have received a letter from a company offering to recover your property for a fee, know that filing directly through claimit.ca.gov costs nothing. Third-party investigators are legal in California but their fee is capped at 10 percent of the property’s value, and any agreement above that is unenforceable.¹¹ Claims involving county probated estates are the one exception with no fee restriction.¹² For a routine cash claim you can file yourself in an afternoon, hiring one rarely makes sense.
