California’s Unclaimed Checking Accounts, Explained

• California holds $1,078,405,026 across 399,537 unclaimed checking-account records under NAUPA code AC01.
• 18,847 of those records are worth $10,000 or more, though the average record holds $2,699.
• Checking accounts escheat under CCP §1530, so a recovery agreement for one is capped at 10 per cent of what is recovered.
• There is no deadline to claim a checking account; the State holds the funds indefinitely.
• Claims of $1,000 or more in cash must be notarized, which covers a large share of checking-account claims given the average balance.

What counts as a 'Checking Accounts' unclaimed property record?

The State Controller’s Checking Accounts category, NAUPA code AC01, holds balances that banks and other financial institutions turned over after an account went inactive. It is one of the largest categories in the State’s system by both record count and dollar value: 399,537 records worth a combined $1,078,405,026. The category is broader than a conventional branch account. It also covers related products such as prepaid card balances, which is why one of the largest reporters below is a Bank of America prepaid card program rather than a standard account.

If a bank could not reach the account holder, could not confirm continued activity, or the balance simply sat untouched, the funds were reported to the State rather than held indefinitely on the bank’s own books.

How does a checking account end up with the State?

Checking accounts escheat to California under Code of Civil Procedure §1530. Most businesses, including banks, file a notice report before 1 November each year and then remit the funds between 1 and 15 June of the following year, on a calendar the State Controller publishes for holders. A bank that misses either date owes the Controller interest of 12 per cent per annum on the amount involved, unless it had reasonable cause or completed the State’s Voluntary Compliance Program, which waives that interest for holders who finish the program.

None of this reflects anything wrong on your part. It is a reporting obligation the bank owes the State, and it explains why a dormant checking account can surface in the Controller’s files years after the last transaction.

How much money is sitting in unclaimed checking accounts right now?

Across California, the checking accounts category holds 399,537 individual records totaling $1,078,405,026. The average record is worth $2,699, but the category is not evenly distributed: 18,847 records are worth $10,000 or more, meaning a meaningful share of the total sits in a relatively small number of larger accounts. Most records are for smaller sums, which is typical of a category built from ordinary personal and business banking balances rather than large one-time payouts.

Which banks reported the most unclaimed checking accounts?

A handful of large financial institutions account for a substantial share of this category. Based on our index of the Controller’s published property records, the largest reporters are:

• Bank of America – California NA (318) — 42,219 records, $140,054,243
• Bank of America – Pre-Paid Card — 33,893 records, $24,431,340
• Bank of America NA — 26,910 records, $76,559,102
• East West Bank — 18,601 records, $61,950,740
• Wells Fargo Bank NA (Apecs 1009) — 15,091 records, $63,656,854
• Union Bank N.A. — 14,907 records, $59,626,093

A record under one of these names does not mean the bank did anything improper. It means the bank complied with its reporting duty once an account met the inactivity conditions set by law.

What does claiming a checking account actually involve?

There is no deadline. California holds unclaimed checking-account funds indefinitely until the owner or their heirs claim them; the only exception involves permanently escheated estates, which is a different situation entirely. Whoever files the claim, whether the owner directly or a recovery service on the owner’s behalf, needs to establish identity and a connection to the account, and claims of $1,000 or more in cash must be notarized. Given that the average checking-account record is worth $2,699, notarization applies to a large share of claims in this category.

If you use a recovery agreement, California law requires it to be in writing, to disclose the nature and value of the property, to state that the Controller holds it, and to give the address where the property can be claimed directly. You must sign it after receiving that disclosure, and you may challenge the agreement at any time if you believe the fee is excessive or unjust.

What fee applies if you use a recovery service?

Checking accounts are reported under §1530, which means a fee to locate, deliver, or recover one may not exceed 10 per cent of the amount recovered. That cap does not extend to every category the Controller holds; estates that reach the State through county probate arrive under the Probate Code, and the Controller states there are no fee restrictions on investigators filing those claims. Checking accounts are not probate estates, so the 10 per cent ceiling applies in full.

No fee may be collected before the Controller approves the claim and pays the owner. California Unclaimed Property Services charges 10 per cent of what is recovered and nothing if nothing is recovered, consistent with that rule.
