Common situations where property can become abandoned are when a person dies with no known heirs or next of kin, when a business is dissolved or when the property owner leaves a jurisdiction without leaving any contact information.
In the U.S. bona vacantia property is handled at the state level. Each state maintains its own unclaimed property office, where it is possible to search for bona vacantia property that may belong to you.
