Unowned property

Unowned property is a tangible thing capable of being owned that currently belongs to no one. English common law describes this condition with the Latin term bona vacantia, meaning ownerless goods. Related concepts include res nullius, things not yet claimed as property either because international agreement bars ownership, as with asteroids under the Outer Space Treaty, or because no one has asserted a claim, and ferae naturae, wild animals of nature that belong to no one while on unowned land, though a landowner who pursues them on private land typically gains a possession right. When property lacks an identifiable owner, such as assets of a dissolved company, an intestate estate with no heirs, or abandoned funds, it typically passes to the Crown or the state, which holds it as custodian rather than permanent owner. The legal framework differs by jurisdiction: England and Wales administer unclaimed estates through the Bona Vacantia Division, Scotland applies the doctrine of ultimus haeres, and the United States handles unowned personal property mainly through lost and abandoned property law.
