The Legal Relation of Plurality of Debtors - Focused on the Joint Lessees in Japan -

Japanese former civil law is enacted in base of French civil law by Bossonade. Japanese existing civil law has two types about co-obligation. one is the 'indivisible obligation', the other is the 'joint obligation. Korean civil law is very similar to Japanese that about the article of co-obligation. This paper is concerned about co-obligation focused on joint lessee, demonstrated Korean & Japanese civil law about co-obligation. Japanese civil law about it is compared to Korean that in this paper. In Korea, joint lessees bear the responsibility 'jointly' by civil code §654. But in Japan, their responsibility is treated case by case theoretically. The divided obligation is a fundamental rule in co-obligation. But It can be the indivisible obligation, joint obligation and ungenuine joint obligation case by case. They are different one after another delicately. That is, in japan, civil legislator tried to pursue a flexibility in concerned of 'joint lessees.' We have to give attention to that the division in them is being collapsed. Indivisible obligation and joint obligation is treated samely in reality. And we cannot discover easily bases that separate joint obligation from ungenuine joint obligation. I wish you could understand it easily and clearly by this paper.
