(a)
If an application is made to the family conciliation court for conciliation proceedings in respect to a controversy between spouses, or a contested proceeding for dissolution of marriage, for nullity of a voidable marriage, or for legal separation of the parties, but there is no minor child whose welfare may be affected by the results of the controversy, and it appears to the court that reconciliation of the spouses or amicable adjustment of the controversy can probably be achieved, and that the work of the court in cases involving
children will not be seriously impeded by acceptance of the case, the court may accept and dispose of the case in the same manner as similar cases involving the welfare of children are disposed of.
(b)
If the court accepts the case under subdivision (a), the court has the same jurisdiction over the controversy and the parties to the controversy and those having a relation to the controversy that it has under this part in similar cases involving the welfare of children.
