A divorce case can be filed under section 13B of Hindu Marriage Act for dissolving the marriage held between you and your wife by a decree of divorce on the grounds of mutual consent.
The jurisdiction for filing divorce can be at following places:
1) Place of marriage (i.e., Asansol)
2) Place where both of you last resided together (if it is Bangalore, then you can file at Bangalore family court itself)
3) Place where the wife is presently living
Divorce on mutual consent will take only six months, i.e., after filing the case, a cooling period of six months waiting is mandatory and on completion of the same, upon other formalities, the court will pass a decree and judgement dissolving the marriage as prayed for.
