Wissen, Nichtwissen und Wissenmüssen von natürlichen und juristischen Personen

Many statutory or contractual provisions’ legal con­sequences depend on whether the addressee knew or should have known a fact. Thus, the question of what natural or legal persons know is of paramount im­por­tance. This paper defines the three key terms “knowledge”, “lack of knowledge”, and “knowledge that one should have had”. Also, it examines under which conditions a third party’s knowledge may be imputed to a provision’s addressee.
