1)seek lump sum amount of Rs 1 crore as alimony from husband
2)ask him to place said amount in fixed deposit in name of daughter
3) considering his salary monthly maintenance of rs 50 ,000 per month is very less . in alternative ask him to pay Rs 1 lakhs as maintenance
4) husband would draw attention of court to fact that you are working and earning Rs 10 lakhs per year to avoid maintenance
5) amicable settlement is best option . you can file petition for RCR if you so desire
