Contra Costa County surplus funds list: 8 records, $1,410,494
When a property here sells for more than the taxes owed, the excess belongs to the former owner until the county’s claim deadline passes. We hold 8 verified Contra Costa County records totalling $1,410,494, each one traced to the official county report it came from.
Surplus Pro opens every record in every state we cover: the amount, the sale reference, the claim deadline and the county source on each one, plus the former owner. Try it for 7 days for $1.99. If you only need California, a one-state pass is $39 for 90 days. No account needed to look.
Surplus funds belong to the former owner and recorded lienholders. Claims are filed directly with the county, and the county does not charge you to claim your own money. This is access to collected public records, not a recovery service and not a claim.
