Abstract：Along with the development of the society, the Division Theory of Forderungsrechte and Sachenrechte inmodem times is questioned to be out-of-time, obsolete, and should be replaced by new approaches, like the The-ory of the Weakness of the Dualistic Structure. But the crisis of the dualistic structure is from the wrong way ofinterpretation, and the traditional property system is still available nowadays. The substantial difference betweenSachenrecht and Schuldrecht is the form of right: Sachenrecht is right of dominion, while Schuldrecht is right ofclaim. The dichotomy in the traditional system does not mean to include all the property rights in reality, and thatis the reason many new kinds of rights is odd if brought into the traditional system. The instance of the creditlizedreal-right and the real-rightlized credit could be located in the dualistic structure made up of Sachenrecht-Schul-drecht in proper interpreting way.
