Ipc 493 494 495

Respected lawyers I want to take advice for my daughter's case. In 2011 we married our daughter to a person who said that he is legally separated. After four months she got pregnant and her husband started dowry demand and physical mental cruelty. Then we bring our daughter to our home. She gave birth to a child. We filed for ipc 498 Meanwhile we come to know that he has not given divorce to his first wife. In 2014 he filed for mutual concent divorce with his first wife in family court. Family court denied divorce to him so he went to high court & concealing facts to high court he got divorce from first wife from retrospective effect from 2010. Is it possible that court can grant divorce with retrospective effect. Now we filed petition for seeking direction to register for under ipc [deleted] in high court. Court directed police to register fir. But police filed B Summary. We also challenged the order of divorce with retrospective effect but it goes against us. What we should do. We are cheated by this person. Can we get any justice? Now he is also living with third lady in live in relationship and having a child. What I should do kindly help
