(b) A spouse who is under the age of majority has standing in a divorce action to sue, answer or plead by a next friend.

(e) Anyone charged as a particeps criminis shall be made a party to a divorce action, upon his or her application to the court, subject to such terms and conditions as the court may prescribe.
(f) In a divorce action where the interests of the minor children of the parties are or may be substantially different from those of either or both of the parents and the best interests of the children may be in conflict with the desires of either or both parents, the court may make the children parties respondent and appoint a guardian ad litem to advocate and protect their rights and welfare.
