First you file Sectin 125 cr.p.c. order in D.V. court. If you have been paying that amount also file those proofs. Further, in the reply file the averments that the amount need not be enhanced and taking your overall earning capacity and her needs that amount was fixed. Once you bring these facts before DV court, that court has the following options: 1. Dismiss her application 2. Enhance the maintenance to some extent taking into consideration of all the facts, but not what she is praying for; (3) If amount is enhanced, the enhanced amount would be set off against the amount of S. 125 cr.p.c. order, means if it enhances upto Rs.3000/-, it subsumes the amount awarded in S.125, so you have to pay only Rs.3000/- not Rs.3000/ and additional Rs.2100/-. This will be clearly spelt out in DV order. (4) Lastly the DV court order will be application according to the judge's direction: from the date of filing of DV petition or from the date of his order on maintenance, but not from the date of the order of S.125 Cr.P.C. Concentrate on first 3 lines of my response without getting sweat.
