Can a divorced women has share of his innocent husbands property?

This is Sashikanth from Andhrapradesh (India) I have one brother-in-law who is innocent but in some needy situation he got married. And He has 2 children( One 4 year boy and 1.6 year girl). After one month of his marriage his wife not have been looking of his husband and also not taken care of her son. The boy was living at his grand mother because he was born with mentally challenged. She also not close with her husband. The leady was so bad as I never seen in my life time like the girl.He alway bitting her husband. We came to know that she was engaged with another man. And the 2nd daughter DNA test proved that Manohar was not the biologically father of the baby child. I need a clarification that: Manohar has a property of one house of single bedroom and a shop whose income supports for his living. He was working as bike wash/cleaning person. My questing is if we apply for divorce then can she have right to take the share of the property which must need for Manohar and his innocent son. His wife also wants settlement.
