Outline of Final Research Achievements

This research focuses on adoption of a stepchild, and the legal alternatives to stepchild adoption in Japan, Germany, and England and Wales. One of the focal points of this research is the interpretation of the best interest of the child in the context of stepchild adoption, both in the wider context of the necessity and nature of stepchild adoption, as well as when courts etc. apply this concept in individual cases. Through comparative research, I have analyzed the merits and shortcomings in the ways that the three jurisdictions regulate stepchild adoption, and the processes set out for such adoptions. As a result, I have attempted to make suggestions for the improvement of the regulation of stepchild adoption in Japan. I have also outlined models for creating alternatives to stepchild adoption in Japan.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、日本法における継子養子縁組、更には未成年者養子縁組全般のあるべき姿を問い直すための一歩となると考える。更に、日本社会において増加し続けているステップファミリーをめぐる法の有り方の再検討につなぎ、多様な家族が生きやすい社会作りに貢献すると思われる。より広く、日本でまだ十分にされていない「社会的親」をめぐる議論の発展にも繋がると期待したい。
