What is Unclaimed Property? Abandoned property can be any financial asset owed to a business or an individual. Property is considered abandoned when there has been no activity and/or contact with the owner for a specific period of time. The State Treasurer's Office is responsible for protecting the assets and advertising the rightful owners' names, in an effort to return the assets to the rightful owners. Abandoned/unclaimed property is NOT real estate or land, automobiles, boats, taxes, or most other tangible properties.
