JapanDifference between special and ordinary adoption?
Ordinary adoption creates a legal parent-child relationship while preserving the child’s original family ties; special adoption fully severs ties with the birth parents, granting adoptive parents exclusive parental rights and responsibilities.
What the Law Says
Japanese family law distinguishes ordinary (futsū yōshi) and special (tokubetsu yōshi) adoption under the Civil Code. The distinction centers on legal filiation and registry effects.
Ordinary adoption is governed by Civil Code Articles 792–809 and allows multiple adoptive relationships; it does not remove the child from the birth family’s koseki (family register). Special adoption, under Articles 817–817-11, terminates all legal ties with birth parents and results in a single, exclusive parent-child relationship recorded in the adoptive family’s koseki.
Special adoption requires court approval, stricter eligibility (e.g., adopter must be at least 25 and 15 years older than the child), and birth parent consent—unless waived by court due to abandonment or abuse. Ordinary adoption has no such procedural hurdles.
What to Do
Confirm eligibility: For special adoption, verify age gaps, marital status, and birth parent consent (or grounds for waiver).
File petition with Family Court: Submit documentation (e.g., consent forms, home study, koseki copies); ordinary adoption only requires koseki registration.
