德国民法典
In the absence of a "Allgemeines Deutsches Bürgerliches Gesetzbuch" (english "General German Civil Code") ADHGB included also general rules for representation ("Stellvertretung") (Art. 52-56 ADHGB), fulfilling ("Erfüllung") (Art. 324-336 ADHGB) and purchase agreement ("Kaufvertrag") (Art. 337-359 ADHGB), that should be "a landmark template" ("„richtungweisende Vorlage“") for future Bürgerliches Gesetzbuch (BGB).
