Dear Sir,
First clarify with your sister whether she wish to continue marriage or not. Please be informed that just filing of Divorce, it cannot be granted. He never get it.

Supreme Court sets alimony benchmark: 25% of ex-husband’s net salary
The Supreme Court has set a benchmark for maintenance to be paid by a husband to his estranged wife, stating that 25% of his net salary might constitute a "just and proper" amount as alimony.
A bench of Justices R Banumathi and M M Santanagoudar made the observation while directing a resident of West Bengal's Hoogly, earning Rs 95,527 a month, to set aside Rs 20,000 as maintenance for his former wife and their son, turning down the man's plea that the amount was excessive. The court said the amount of maintenance or permanent alimony must be sufficient to ensure that a woman lived with dignity after separating from her husband.
===========================================================================
MAINTENANCE AND CUSTODY
THE LEGAL rules relating to the maintenance and custody of children
are found in the personal laws (including statutory) of the various religious
communities, and in the Criminal Procedure Code. There is, therefore,
no uniformity in this matter except to the limited extent to which the
provisions of the Criminal Procedure Code apply. We shall first deal
with the latter and then proceed to examine the personal laws of the
different religious communities.
