California Unclaimed Money

Unclaimed money generally refers to cash and cashless financial assets that remain untouched for a statutory amount of time or dormancy period. These include bank account balances, uncashed checks, travelers’ checks, stocks and bonds, refunds, life insurance, and other public benefits. The dormancy periods of these financial instruments vary. The government or an approved business taking temporary possession of assets is a process called escheatment.
