Constructive

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.

constructive adj. a legal fiction for treating a situation as if it were actually so. Some examples help to clarify this term: although Jeremiah Gotrocks does not have the jewelry in his possession, he has the key to the safe deposit box and the right to enter so he has "constructive possession"; although there is no written trust document, George Holder has picked up $10,000 in bearer bonds from the post office box of his niece Tess Truehart who gave him her post office box combination while she was traveling in Europe--this makes Holder her "constructive trustee." (See: constructive fraud, constructive eviction, constructive notice, constructive notice, constructive possession, constructive trust)

     4. Constructive breaking into a house. In order to commit a burglary, there must be a breaking of the house; this may be actual or constructive. A constructive breaking is when the burglar gains an entry into the house by fraud, conspiracy, or threat. See Burglary, A familiar instance of constructive breaking is the case of a burglar who coming to the house under pretence of business, gains admittance, and after being admitted, commits such acts as, if there had been an actual brooking, would have amounted to a burglary Bac. Ab. Burglary, A. See 1 Moody Cr. Cas. 87, 250.
     5. Constructive notice. Such a notice, that although it be not actual, is sufficient in law; an example of this is the recording of a deed, which is notice to all the world, and so is the pendancy of a suit a general notice of an equity. 4 Bouv. Inst. n. 3874. See Lis pendens.

     7. Constructive fraud. A contract or act, which, not originating in evil design and contrivance to perpetuate a positive fraud or injury upon other persons, yet, by its necessary tendency to deceive or mislead them, or to violate a public or private confidence, or to impair or injure public interest, is deemed equally reprehensible with positive fraud, and therefore is prohibited by law, as within the same reason and mischief as contracts and acts done malo animo. 1 Story, Eq. Sec. 258 to 440.
