That which exists, not in fact, but as a result of the operation of law. That which takes on a character as a consequence of the way it is treated by a rule or policy of law, as opposed to its actual character.
For example, constructive knowledge is notice of a fact that a person is presumed by law to have, regardless of whether he or she actually does, since such knowledge is obtainable by the exercise of reasonable care.
For example, possession of the key to a safe-deposit box is constructive possession of the contents of the box since the key gives its holder power and control over the contents.
