Appraise your counsel if you are paying Rs.13000/pm as per court order or on your own. Hope you have the record. Hope you also have the irrefutable record of your liabilities.
The spouse may claim as per past living standard and needs at current location.
The spouse may claim later the circumstances have changed and expect increased amounts.
The husband/father may have to pay maintenance to spouse/children and reasonable expenses to marry the daughter within his reach and resources.
