498A case mediation decision

Respected members I and my husband has been mutually agreed for divorce in 498a mediation requested by husband. We filed divorce case as per the decision but husband did not receive summons. He now filed divorce case at their place where we cannot attend the court given the security reasons. Would it be necessary to attend the court if I accept his summons or lawyers can represent me in the court in my absense? Until when the 498a case could be on hold as it's been 6 months post mediation order. Kindly suggest the best way forward. Thank u in advance.
