If u choose to file a divorce application under section 13 of HM Act, ur wife can definately file a application under section 24 or 25 of the said act and this application shall be disposed off within sixty days of filing, but here the relief comes, whatever maintenance amount get decided in favor of ur wife, it will be calculated and adjusted into final amount ordered under section 125 crpc, you will have to specifically elaborate and plead in proceedings of HM Act or DV Act that other maintenance proceedings are also pending against u, Many citations and leading case laws are available in DMC and other journals.
Remember one more thing that divorced wife is also entitled for maintenance till she remarry, even if she found of loose character, having suffiecient means or had made cruelity against u, So always engage a good civil lawyer, because these kind of cases always rely upon evidence of both parties and good cross examination.
