1) is your wife working ? what are her qualifications ? how many years since you have been married?
2) alimony to be awarded is at discretion of court . it depends your income , years of marriage, life style of husband etc.
the amount of alimony to be paid cannot be fixed by law as it varies from case to case; the most important aspect is to maintain a balance while deciding the same. In divorce cases, the courts must factor in the wife’s status and lifestyle while fixing alimony to ensure that she lives in reasonable comfort considering her status and mode of life she was used to when she lived with her husband.
3) in your case the court may award lumpsum payment of around Rs 15 lakhs .
