49Parties to proceedings under this Act
(1)Where in a petition for divorce or judicial separation, or in any other pleading praying for either form of relief, one party to a marriage alleges that the other has committed adultery, he or she shall make the person alleged to have committed adultery with the other party to the marriage a party to the proceedings unless excused by the court on special grounds from doing so.
(2)Rules of court may, either generally or in such cases as may be prescribed by the rules, exclude the application of subsection (1) above where the person alleged to have committed adultery with the other party to the marriage is not named in the petition or other pleading.
(3)Where in pursuance of subsection (1) above a person is made a party to proceedings for divorce or judicial separation, the court may, if after the close of the evidence on the part of the person making the allegation of adultery it is of opinion that there is not sufficient evidence against the person so made a party, dismiss him or her from the suit.
(4)Rules of court may make provision, in cases not falling within subsection (1) above, with respect to the joinder as parties to proceedings under this Act of persons involved in allegations of adultery or other improper conduct made in those proceedings, and with respect to the dismissal from such proceedings of any parties so joined; and rules of court made by virtue of this subsection may make different provision for different cases.
(5)In every case in which adultery with any party to a suit is alleged against any person not made a party to the suit or in which the court considers, in the interest of any person not already a party to the suit, that that person should be made a party to the suit, the court may if it thinks fit allow that person to intervene upon such terms, if any, as the court thinks just.
