My wife email was open on my daugther's laptop, which was with me and my daugther is with my wife now. She deserted me and i sent a legal notice to her to come back or for divorce. While preparing her reply, she along with her family members are distorting facts like one is sayin mention Rs 40,000. other one says 4 lacs. then 40 lacs, etc. in emails. I got evidence of all. My divorce case is already going on. What additional action/ case i can do basis these evidences on wife and others.
