how will it be recovered

1. 2 yrs divorce pending....now wife files say and 24hma few months back. arrears pile in thousands and wife giving all sorts of reason starting from her piles operation to her mothers surgery.
2. she files rcr in other court wit 125 and dv. husband knows she never gnna come baqck so gave a say in rcr +125 that wife deserted , he ready to reunite .
3.no interim in 125 but now she feasting on 24hma asking for arrear clearance first....even she wanting divorce but only after torturing husband for years and settling for huge one time settlement.
4. magistrate knows but just warning her and not taking any strict action......asking for mcd instead of contesting for years.
5.now husband frustrated in 2yrs , if he withdraws divorce or it gets dissmissed due to non payment of arrears, will the arrea be recovered by any attachment or crpc......
6. husband is petitioner in divorce but fed up of paying interims and case not moving fast, lawyer saying higher court orders also waste of money as matrim. caswes run too slow and mostly end in mcd shelling by husband a lump .

Yes the wife can claim the arrears by filing an execution petition before court.
