Costa Mesa unclaimed business money
Updated
The California State Controller holds about $4.3 million for 124 business-type owners with Costa Mesa addresses whose open records total $10,000 or more each.
What the money is
The largest kinds of property held for Costa Mesa business-type owners:
| Property type | Amount | What it usually is |
|---|---|---|
| Stock returned by the post office | $661k | share certificates or statements returned by the post office as undeliverable |
| Underlying shares | $491k | the shares themselves, not just their dividends, after the account went dormant |
| Dividends | $423k | dividends that were declared but never reached the shareholder |
| Checking accounts | $364k | balances left in checking accounts after the bank lost contact with the account holder |
| Insurance proceeds for beneficiaries | $225k | insurance proceeds payable to a named beneficiary, often a trust or a company |
The typical Costa Mesa owner on this list is owed $16,434, below the statewide median of $18,087. 21% of the owners here are trusts or estates, which follow different claim rules from companies.
Claiming it
A Costa Mesa business claims from the Controller like any California business: an authorized person signs the Controller's claim form in wet ink, in front of a notary for $1,000 or more in cash or for any securities, and the package includes proof of authority, the FEIN and the address the holder reported. With 51% of local owners holding more than one record, it pays to search every name and address the business has used.
