Section 1517. No action for divorce may be instituted by the husband or wife, as the case may be if such spouse has consented to or connived at the acts under Section 1516 (1) and (2) upon which the action for divorce is based.

If the ground of action for divorce under Section 1516 (10) has resulted from the act of the other spouse, the action for divorce based upon such ground may not be instituted by such other spouse.

Where the action for divorce based upon the ground under section 1516 (8) has been instituted, the Court may not pronounce judgment to effect the divorce if the behavior of the husband or wife that causes the bond to have been executed is a minor cause or of no importance in relation to peaceful cohabitation as husband and wife.

In such a case if no order of the Court effecting the insane spouse to be an incapacitated person has yet been given, the said person shall apply to the Court in the same case for an order effecting the insane spouse to be an incapacitated person.

The said person may, if deemed suitable, also apply to the Court for giving the order under Section 1526 and Section 1530.

In case where the spouse alleged to be an insane person has not yet been adjudged incompetent, and if the Court deems that such spouse should not be judged incompetent, the case shall then be dismissed. If the spouse is deemed suitable to be adjudged incompetent but an order to effect the divorce should not yet be given as yet, the Court shall adjudge the spouse to be an incapacitated person and may not give order concerning the guardian or appointing other person to be guardian under Section 1463 while the application for divorce will be dismissed, and the Court may in this connection give an order determining living allowances. In case where the spouse is deemed to be insane and should be adjudged incompetent by the Court and the application for divorce should also be granted, the Court shall issue an order in the judgment effecting such spouse to be an incapacitated person, appointing a guardian and allowing the divorce.

In case there the Court deems that the ground upon which the claim for divorce is based is not proper to the condition of the incapacitated spouse who is going to divorce the other spouse, ir it is not proper under such circumstances that divorce should be allowed, the Court may not pronounce the judgment to effect the divorce.

Section 1520. In case of divorce by mutual consent, the spouses shall make an agreement n writing for the exercise of parental power over each of the children. In the absence of such agreement or an agreement thereon cannot be reached, the matter shall be decided by the Court.

In case of divorce by judgment of the Court, the Court trying the divorce case shall also order that the parental power over each of the children belongs to any party.

Section 1524. If the ground of action for divorce under Section 1516 (3), (4) or (6) has arisen through an act of the party at fault with the intention to make the other party so intolerable that action for divorce has to be entered, the other party is entitled to compensation from the party at fault.

Section 1525. The compensation under Section 1523 and Section 1524 shall be decided by the Court according to the circumstances, and the Court may give an order for a single payment thereof or payment in installments as may be deemed suitable by the Court.

Section 1526. In a case of divorce, if the ground for divorce has derived from the guilt of only one party, and the divorce will make the other become destitute deriving insufficient income out of his or her property or business which used to be carried on during the marriage, the latter is entitled to apply for the living allowances to be paid by the party at fault. The Court may decide whether the living allowances be granted or not by taking the ability of the grantor and the condition in life of the receiver into consideration, and the provisions of Section 1598/39, Section 1598/40 and Section 1598/41 shall apply mutatis mutandis.
