You have to gather evidence about the activities and submit to the Court.

u need to prove that the second marriage was solemnized legally and the requirements of law were complied with. to constitute a hindu marriage, saptapadi/saat fere is essential or the marriage needs to be registered. living in relation may solely give a presumption that the couple is residing as a husband and wife.

Vijya ji, still on run.

No problem, you have to appear on that place and call the police and made a fight with that girl and then police himself will provide evidence that the guy is living with that girl and you create problem over there. But it will prove your case.
