Upon the death of the parent granted with the parental rights, major doctrines and precedents, on the basis that the current laws are silent in this regard, have adopted a position that the rights are spontaneously resumed by the surviving parent. Such a position, however, particularly in a situation in which the parental rights were first awarded or reassigned by the court, may have neglected the supervisory privileges of the court. While in Japan the laws are also silent in this regard, various opinions were provided under different doctrines and precedents. With reference to such opinions, this article is to review and examine the validity of the doctrines and precedents in our country.
