How the get the petition filed by the wife

When the maintenance petition is presented in the court, the court will order copy of the petition to be sent to the husband.   Wait for some more time.    

You will definately receive a copy of the petition filed by your wife through process server or via postal department

if you donot receive it before hearing

then be present in hearing and tell Hon. Court that you have not received Maintainous petition and request   court for a copy of petition  and request to give another date for hearing so as to study the petition.

no problem take date on the particular day when the case was listed and say about non receving of peititon copy and need some time and in mean time if your garner any evidences then take them and file about her working salary slip
