Res nullius
A thing belonging to no one.
Res nullius is a Latin term referring to a thing that belongs to no one and is therefore available for appropriation.
Res nullius, literally meaning “a thing of no one”, denotes property in law that is not owned by any natural or legal person. This includes, for example, wild animals in their natural state and objects that have been clearly abandoned without any owner remaining.
In Dutch law the concept is relevant to the acquisition of ownership by occupation or taking possession. It determines when property may be appropriated without the consent of a former owner, provided that no owner exists.
In practice, res nullius most commonly arises in relation to stray animals or abandoned goods found on public land, where the finder may become owner subject to certain conditions.
“Because the fish in the river was regarded as res nullius, the fisherman could lawfully catch it without the consent of an owner.”
