일본 2017년 개정 민법 중 사해행위취소권에 관한 소고– 절대적 효력설을 중심으로 -

The Japanese Civil Code, revised in 2017, abolished the existing Relative effect theory of the creditor’s revocation right and introduced the Absolute effect theory. There have been several criticisms regarding the Relative effect theory that the effect of the creditor’s revocation right does not extend to the debtor, as it could cause many theoretically complex problems. The Absolute effect theory, which extend the effect of revocation to the debtor, seems to be positively evaluated by the academic and practical circles. However, it is necessary to analyze whether the Absolute effect theory can overcome all the difficulties under the Relative effect theory or whether it may cause another confusion in interpretation about the each specific issues that have been associated with the creditor’s revocation right.  In particular, as there are some interested parties who do not have the effect of revocation, such as the subsequent trader's former even in the absolute effect theory, the relationship among them should also be examined closely. The introduction of absolute effect theory has led to a convenience in theoretical composition. However, since the interpretations that the precedents have firmly established were excluded by introducing the Absolute effect theory, it is necessary to closely observe the future progress on how legal relations will be built in the future.
