In this scenario the estate needs to be referred to the Bona Vacantia Division of the Government’s Treasury Solicitor Department.
Once they have administered the estate any money stays with the government until someone with a claim steps forward. There are a number of companies whose business is finding the heirs to the bona vacantia estates. You may have seen some of the situations which arise on the TV programme Heir Hunters.
The bona vacantia website provides full details of all the unclaimed estates. The list includes details such as name, age, place of birth, place of death, marital status and relevant documents held by the Treasury Solicitor Department.
