thanks for your replies. I am trying my best to express it clearly again.
A divorce petition under adultery ground was filed where the first respondent is wife(lady) and the second respondent is her boyfriend. In reply to the divorce petition, the lady filed her WS after 6 months and her boyfriend was set as an ex parte after he failed to appear before the court in his FINAL CHANCE to give WS. (but he filed vakalat and took one court adjournment). After one week, he submitted his set aside petition for ex parte. In the set aside petition, he said that he came to court premises and was in court premises, but was lost in premises and hence failed to appear before this court as he was new to court premises. He also said his counsel asked him to appear personally before the court. Will it be acceptable by the court. Does it have satisfy the sufficient reason to set him aside.
