There is over $5 BILLION belonging to 8.2 million people and businesses in California sitting in the State of California Unclaimed Property (UCP) database at www.sco.ca.gov/col/ucp.
If there is no activity in an account for over 3 years and the business cannot reach the owner (often due to address changes, death, etc.), the money reverts to the State. You'll see unclaimed interest, dividends, savings accounts, rebates, insurance settlements, rebates, etc. in the database.
The UCP website has a handy search engine at http://scoweb.sco.ca.gov/UCP/ that lets you search for unclaimed property by name and city. There are nearly 26,000 unclaimed property listings just in Thousand Oaks! Aleta Smith, you are owed $421 in dividends! Claim your money! Darrell Taylor, Verizon owes you $50! Crystal Hawkins, 21st Century Insurance owes you $305!
This database is for real. I found money for 3 people and business that I know in there! It makes it fairly easy to claim the property. You can fill out on online form, print and mail with required documentation (usually need a photo ID, a document showing your Social Security Number, your address and something showing the property is yours). The State must pay you within 180 days.
The database also lists property that is still with the business that you can claim directly, prior to reverting to the State.
So check it out! You might find some spare cash in there for you, a friend or a relative! And for unclaimed money in other states, check out www.unclaimed.org.
