During the pendency of an action for divorce or legal separation, the court may, upon written stipulation of both parties that they desire to attempt a reconciliation, enter an order suspending any and all orders and proceedings for such period, not exceeding 90 days, as the court determines advisable to permit the parties to attempt a reconciliation without prejudice to their respective rights. During the suspension period, the parties may resume living together as husband and wife and their acts and conduct do not constitute an admission that the marriage is not irretrievably broken or a waiver of the ground that the parties have voluntarily lived apart continuously for 12 months or more immediately prior to the commencement of the action. Suspension may be revoked upon the motion of either party by an order of the court. If the parties become reconciled, the court shall dismiss the action. If the parties are not reconciled after the period of suspension, the action shall proceed as though no reconciliation period was attempted.
