Bona vacantia (Latin for "ownerless goods") is a legal concept associated with property that has no owner. It exists in various jurisdictions, with consequently varying application, but with origins mostly in English law.
Bona vacantia is applied according to the laws of the relevant province, and the roots of the laws may be traced to Roman law.
Similarly to England, unclaimed money will mostly revert to the Crown who may then make further distribution. Unclaimed property other than money might also be claimed on behalf of the Crown but (as with the UK jurisdictions) this is not inevitable.
Bona vacantia is partly a common law doctrine and partly found in statute. It deals with:
For most of England and Wales, the Bona Vacantia Division of the Government Legal Department is responsible for dealing with bona vacantia assets on behalf of the Crown. If no heirs to an estate can be found then the assets are realised and the balance is transferred to HM Treasury. The division deals only with solvent estates whose net value exceeds £500. The assets of dissolved companies automatically pass to the Crown by law. They are realised by the division and the revenue passed to the Exchequer, although the division has a power to disclaim onerous assets. Liabilities associated with assets do not automatically follow those assets into bona vacantia. Care should be taken to distinguish between assets remaining when dissolution commences (which, e.g., might be distributed to shareholders or others in that process) and those that for various valid reasons remain undistributed at the end of dissolution. Some assets might only come to notice after dissolution has taken place.
For assets based in Cornwall and within the traditional boundaries of the county palatine of Lancashire, Farrer & Co solicitors deal with bona vacantia on behalf of the Duchy of Cornwall and the Duchy of Lancaster respectively. In both cases, if no rightful owner is found for the assets, the assets legally pass to the respective duchies. Current practice for both is to donate these assets to charity. In Lancaster the beneficiaries are the Duchy of Lancaster Benevolent Fund and the Duchy of Lancaster Jubilee Trust, while in Cornwall The Duke of Cornwall’s Benevolent Fund receives the assets.
