If the parties to a marriage that is subject to an action to rescind the marriage or an action for divorce have a child who has not yet reached adulthood, the family court must take into consideration the domicile or residence of that child in applying the provisions of Article 6 and Article 7 to the litigation connected with that action.

①On petition, in a judgment upholding a claim relating to an action to rescind a marriage or an action for divorce filed by either the husband or the wife against the other, the court must make a judicial decision designating the custodial parent and disposing of other such matters related to child custody; disposing of matters related to the distribution of property; designating the person exercising parental authority alone (meaning a person who exercises parental authority alone pursuant to Article 824-2, paragraph (3) of the Civil Code; the same applies in paragraph (4)) (limited to designation concerning matters for which parental authority needs to be exercised in connection with the rescission of the marriage or divorce; the same applies in that paragraph); or disposing of matters under the provisions of Article 78-2, paragraph (2) of the Employees' Pension Insurance Act (Act No. 115 of 1954) (collectively referred to below as "ancillary disposition").

⑤The proceedings in an examination of the facts are not open to the public provided, however, that the court may permit observation by a person whom it considers to be appropriate.

⑥If a court finds it to be reasonable, the court may, after hearing the opinions of both parties, perform procedures on a hearing date referred to in paragraph (4) by a method of communication that enables the court and both parties to simultaneously communicate with one another by audio transmission as provided for by the Rules of the Supreme Court.

①In the case where a petition for a disposition of matters related to child custody referred to in Article 32, paragraph (1) (limited to a disposition concerning the sharing of expenses required for the custody of a child) has been filed, if the court finds it necessary, the court may, on petition or on its own authority, order a party to disclose information on the party's income and assets.

②If a petition concerning matters related to the distribution of property as referred to in Article 32, paragraph (1) has been filed, the court may, if it finds it necessary, order a party to disclose information on the status of the party's property, upon petition or sua sponte.

③If a party who has been ordered to disclose information pursuant to the provisions of the preceding two paragraphs fails to disclose that information without a legitimate reason or discloses false information, the court issues a ruling imposing a civil fine of not more than 100,000 yen on the party.

①If a petition for the designation of a person to have custody of a child or for other matters related to child custody as referred to in Article 32, paragraph (1) (excluding matters related to the sharing of expenses required for child custody) has been filed, and there are no circumstances found to make it inappropriate in light of the child's physical and mental condition, and the court finds it necessary for an examination of the facts, the court may encourage the parties to carry out a trial implementation of contact with the child.

②In encouraging the trial implementation under the preceding paragraph, the court may specify the method of contact, the date, time and place of contact, and whether a family court investigator or another person is to be present or otherwise involved, and may also impose on the parties a condition prohibiting words or conduct that have a harmful effect on the mind and body of the child, or any other condition it finds appropriate.
