hi, my brother was married and has a kid 1 year old. his wife was chatting with her old boy friend. my brother used to check her mails without her knowledge sometimes and he found out few chat messages in which they had shared their love. my brother has saved the chat messages and has printouts of them. He wants mutual consent divorce. but his wife is not ready to divorce as she apologises. Is this proof enough to proove adultery? if so, is it necessary for my brother to pay her and the child some kind of compensation or maintenance. security? his wife is not working. will my brother be punished for checking her mails and taking printouts if she files a case against him? 

It is really sad what your brother is going through. First, I think, he should try and forgive his wife(difficult but not impossible) A child always helps to strengthen the bond between parents. The stark reality is that while men can go to jail for adultery, Indian women cannot ( because she is sati savitry and of course there are no prostitutes in India). There are women who have a child with someone elseand still traumatize their husbands by not leaving them. The law is on the women's side. legally, there is very little you can do.
