Required help - whether any time limit for filing dv

As per Hindu Marriage Act., having second marriage without nullifying first marriage is null & void. Since, you came to know that she got second marriage, you may file for a dissolution of of first marriage and exempt from paying maintenance.

Thanks for your valuable suggestion, We have filed Nullity of marriage petition which is pending in Court, and after that nullity petition, she came to our home with her two lawyers and relatives and taken back all her "Streedhan" after that she filed a mutual divorce petition 13 B in September 2013, in 13-B petition court fixed next date in December 2013, she again came to court and signed her presence, as this was a formal date fixed by court, on the very next date in March 2014, she presented an application for withdrawal of 13-B, which was dismissed by the court and from that day she is absent from the court.

While in Nullity of marriage petition, either she or her lawyer came regularly, but petition is pending till date.

Whether we have to fight for the DV & maintenance petition filed by her after all these above circumstances ?

"She has got second marriage without divorce and she is already presented 13-B in which she has written that all the "Streedhan" has taken back and she will never demand for maintenance in future, so this DV petition filed after 21 months she left her matrimonial house, should be quashed ?"
