The intermediation system in Korea has been adopted from Japan and succeeded to that of the Federal Republic of Germany. So, the system is also similar to the system of broker based on the laws of the Great Britain and the United States of America. The system has some possibilities of legal problems between an intermediary and a client. Thus, with the view to the problems, we need to review the legal theory on the system in order to eliminate the problems. We should also provide legal solutions or theories for legal enactment in case of the conflict. Through the publicity of the tasks of civil law revision in November, 2004, the Department of Justice has already provided the total four provisions followed by the 692th act of the 13th clause in civil law after commission contract for a previous announcement of the civil law revision. The contents of civil revision law constitutes the intermediation contract as an independent type of contract, but it follows a lot of regulations of commission contract. The main contents of payment responsibility which consists of basic elements is somewhat similar to that of commission contract. In this regard, they criticize the contents of the contract because it only includes a symbolic meaning for the provision of the contract in civil law and it ignores the legal solution for the conflict. This study focuses on the theory on the interpretation of the intermediation contract and analyzes precedent cases in the Federal Republic of Germany. Based on the systems, this paper reviews the interpretation and legal problems of the intermediation contract in the view of the civil law revision. This study, as a result, may contribute the participants to discuss and review the topic of intermediation contract.
