complain against brother in law

The Protection of Women from Domestic Violence Act 2005 is an Act of the Parliament of India enacted to protect women from domestic violence. Inform to your husband and his brother about this act consequences. You can give police complaint even on line grievances also. 

Hello,

You can file complaint against husband's brother. However I will advice to solve the issue by amicable discussion. Now your sister is not having any complaints / allegations against husband so discuss issue with husband by involving parents and elders. 

Thank you sir for your reply. How can my sistermsister online complain? Also can my sister complain for domestic violence without proof. She does not have much proof.
