Constructive possession[1] is a legal fiction to describe a situation in which an individual has actual control over chattels or real property without actually having physical control of the same assets.
Constructive possession is also essential in the seizure of goods by private or government authorities.
For example, if someone chains someone else's car to an immovable object, they have taken possession of it even though they have not moved it.
Constructive possession can also refer to items inside of a vehicle.
The owner and driver of the vehicle can be in constructive possession of all things inside their car.
