Dv and 125 maintenance setoff ?

You have voluntarily accepted monthly payment of maintenance @ 12,000/- + 10,000/- to your wife and children, which may continue or make one time settlement. 

However, it is your mutual decision and not a legal problem.

If you find there is some concealment or change in circumstances request your lawyer to move appropriate application(s) before the Court for modification / alteration and or cancellation of order of maintenance.

Thank you sir.

Only the part of CrPc 125 maintenance amount was mutually agreed.

but the interim amount ordered under DV act was given by respected CJM.

Recently I got the documentary proof of my wife job which was hiding from the initial stage of DV and 125 proceeding by wife.

So can I reduced the amount in the above ground?

You may approach your lawyer to file an appeal u/s 19 of the PWDV Act, 2005 before District & Sessions Judge assailing the order passed by CJM in the case, incorporating the order of mutually agreed amount of Rs. 12,000/- being granted / paid by you.  

Sir,

Is there any time limit for file appeal u/s 19 PWDV

Of course there is limit for every thing in the world, including every law.

It would be better either to read provision of law or consult the lawyer engaged / paid by you.
