Person X1 was female and underwent surgery to become a man. X1 registered as a male and married a woman X2 in 2008. In 2009, X2 bore a child. In 2012, X1 applied to have the family registry reflect that X1 was the child’s father and that the child was born while X1 and X2 were married. The ward mayor in charge of changes to family registries held that there was a problem with the application because Article 774 of the Civil Law was inapplicable to the child’s situation as the child was not related by blood to X1. X1 did not comply with the ward mayor’s request to fix the application, so the ward mayor filled in the family registry for the child with a blank for father and a note that the child was X2’s oldest son. X1 and X2 filed suit to have X1 added as the child’s father on the grounds that the child should be presumed to be a “legitimately” born child based on Article 772 of the Civil Law. The Supreme Court held that the child should be presumed to be the son of X1, overruling the lower court and the ward mayor’s decision. The court reasoned that under Article 3.1 of the Gender Identity Disorder Law, a transgender man should be treated for all purposes under the law as a man. The court held that this includes being able to marry and have a “legitimate” child. Following this decision, the Ministry of Justice issued a notification on 27 January, 2014 directing that this procedure be followed for any similarly situated families. Subsequently, the state changed the family registry for forty-five such couples to reflect that both parents are their children’s parents.
