Article 41Parties to an Action to Rebut the Presumption of Legitimacy
第四十一条（嫡出否認の訴えの当事者等）
If a father dies before the birth of a child, or dies within the period specified by Article 777 (limited to the part related to item (i)) or Article 778 (limited to the part related to item (i)) of the Civil Code without filing an action to rebut the presumption of legitimacy, a person whose right of inheritance is harmed because of the child, or any other blood relative of the father's within the third degree of kinship, may file an action to rebut the presumption of legitimacy only within one year from the day on which the father died.
If a father dies after filing an action to rebut the presumption of legitimacy, a person permitted to file an action to rebut the presumption of legitimacy pursuant to the provisions of the preceding paragraph may be substituted in the court proceedings within six months from the day of the father's death. In that case, the provisions of the second sentence of Article 124, paragraph (1) of the Code of Civil Procedure do not apply.
父が嫡出否認の訴えを提起した後に死亡した場合には、前項の規定により嫡出否認の訴えを提起することができる者は、父の死亡の日から六月以内に訴訟手続を受け継ぐことができる。この場合においては、民事訴訟法第百二十四条第一項後段の規定は、適用しない。
If a former husband specified in Article 774, paragraph (4) of the Civil Code files an action to rebut the presumption of legitimacy pursuant to the provisions of Article 775, paragraph (1) of that Code (limited to the portion related to item (iv)), if there is a person (other than the father) who marries the mother during the period from the time of conception to the time of the birth of the child after dissolution or rescission of the mother's marriage to the former husband, an action to rebut the presumption of legitimacy naming those persons as defendants must be filed by joining with the action to rebut the presumption of legitimacy.
民法第七百七十四条第四項に規定する前夫は、同法第七百七十五条第一項（第四号に係る部分に限る。）の規定により嫡出否認の訴えを提起する場合において、子の懐胎の時から出生の時までの間に、当該前夫との婚姻の解消又は取消しの後に母と婚姻していた者（父を除く。）がいるときは、その嫡出否認の訴えに併合してそれらの者を被告とする嫡出否認の訴えを提起しなければならない。
The oral arguments and judicial decisions in an action to rebut the presumption of legitimacy filed by joining pursuant to the provisions of the preceding paragraph must not be separated from one another.
前項の規定により併合して提起された嫡出否認の訴えの弁論及び裁判は、それぞれ分離しないでしなければならない。
When a judgment in an action to rebut the presumption of legitimacy concerning a child whose paternity has been established pursuant to the provisions of Article 772, paragraph (3) of the Civil Code becomes final and binding, the court is to provide notice of the contents of the judgment to the former husband (limited to a person whose name and domicile or residence are indicated in the case record) referred to in Article 774, paragraph (4) of that Code.
裁判所は、民法第七百七十二条第三項の規定により父が定められる子について嫡出否認の判決が確定したときは、同法第七百七十四条第四項に規定する前夫（訴訟記録上その氏名及び住所又は居所が判明しているものに限る。）に対し、当該判決の内容を通知するものとする。

public prosecutor
検察官
The official who brings a prosecution (公訴) for a crime before a court (Code of Criminal Procedure, Article 247), and who may decide not to prosecute where, in view of the offender's character, age and circumstances, the gravity and circumstances of the offence and what happened after it, prosecution is not needed (Article 248). In criminal cases a public prosecutor asks the court to apply the law correctly and oversees the carrying out of its judgments; and, as the representative of the public interest, a public prosecutor also does the work other laws and regulations assign to a public prosecutor, which is not limited to criminal cases (Public Prosecutors Office Act, Article 4). A public prosecutor may investigate any crime (Article 6, paragraph (1)). Public prosecutors work through the public prosecutors offices (検察庁): the Supreme, High, District and Local Public Prosecutors Offices (Article 1).
