Need some advise:This is with related to my sister and her husband.One year back we register a case against my brother in law for domestic violence,dowry harassement and adultery.It has been a year,so the cases in the court are in progress.Meanwhile my brother in law started living illegally with a women who is his collegue for the last 10 months.We named her also in that complaint against him.Now i heard and i have seen that the lady is pregnant and my brother in law is the reason for her pregnancy.Still arguments are going on in the court.How can we proove and face this immoral act.My sister is already having a girl who is 12 years old.my brother in law harassed my sister in the past for a male child also.Already enough cases has been filed.Is there any way i can proove my brother-in-Law relationship with that lady or any fresh cases i can file against him so that i can stop him in further damaging us emotionally and mentally.
