(1) This rule applies where the judgment or order has not been served.
(2) If the order requires the judgment debtor not to do an act, the court may make a committal order or sequestration order only if it is satisfied that the person against whom the order is to be enforced has had notice of the terms of the order by being —
(a) notified of the terms of the order by post, telephone, electronic communication or otherwise; or
(b) present when the order was made.
(3) The court may make an order dispensing with service of the judgment or order under rule 53.3 or 53.4 if it thinks it just to do so.
