Exparty

Dear Sir, My wife has file Restitution of Conjugal Rights in 2014, she has filed intrem application under HMA24 asking for maintenance, for the past 2years 3 judges have been changed and a new judge has come now. For the first hearing the judge gave me next date, I could not attend 2nd hearing since I was sick, when I appeared for the 3rd hearing the judge straight away said it has been posted for orders. Now my query is without me present in the previous hearing there were arguments done, now I want to place the true facts on record, how to set this exparte aside. Please help me what do next? How to ask for my prayer in the honorable court? Is there any application for setting aside the order before my arguments?
