Nri child

Dear all legal experts i am British by citizenship with OCI and i currently residing in India but my wife is Indian national and Indian passport holder. my daughter by birth she is British and minor child under 2 years. we have moved to India last year right now, she stays in India through entry visa which i applied through FRRO . me and my wife are not divorced but separated living our life as we have lots of conflicts many years which are not solvable. Currently in India I am keeping my daughters' British passport . i support my wife and child but my wife doesn't want to move in with me or live together so she stays with my daughter in her parents place. recently my wife demanded give over her passport so that she can my minor daughter abroad stating some family reunion event . i refused to give it because I have no trust she will come back or find a employment out and i have to loose my daughters contact once for all if she leaves India with my daughter. Can my wife being separated can apply Indian citizenship for my minor daughter without my permission or does she need to get divorced from me before she can apply this in India . Is there any way i can inform Indian immigration about this situation ?
