Ex-parte divorce decree has been granted to me (petitioner)

 "respondent has already filed a petition to set aside ex-parte on 16.09.2015 during the case proceeding, i mean can she file for second
time)" This statement does not make sense.  You cannot file a petition to set aside a final Order during the case.  The statement is self-contradictory. In any event, your ex-parte divorce will get reversed easily... not knowing the details, I cannot give an answer with certainty. And no, you cannot re-marry while the time for filing an appeal or petition to set aside the Order has not expired.  You seem to be in a hurry to jump from one problem to another... 

Dear Jayakumar,

2. Does the respondent go for an appeal to set aside ex-parte order ?
( respondent has already filed a petition to set aside ex-parte on

time)

Ans: Yes, the Respondent can go for an appeal and the appeal period is 3 months from the date of decree. The Respondent has to file for set aside petition before that Family Court which has pronounced the divorce decree. During case proceeding, no set aside petition can be allowed by the court.
