P S Neog - Jorhat

Name: P S Neog
Comments: She left (without my consent) 2yrs ago with 1.5yr girlchild
I am keen on reestablish my family, so didn't file any case/FIR (although she threatened me with 498a/DV/taking away the child)
tried all my family channels (VERY URNESTLY & SINCERELY) to make her understand what is good for our child
I am still paying my insurance premiums
seeing no response I thought of going to courts
Now suddenly it seems her family is interested in negotiations
I told them:
1. Come back w child, I'll accept you if your family stops maddeling with our lives (I feel she is a good woman, but misguided by parents/sibling)
2. Otherwise I'll fight for physical & legal custody of child
3. I might ask for divorce as well

My question:
1. How do I find out if any FIR/case is made with police/court/mahila samity ASAP?
2. Do I execute a prenupital agreement before accepting her saying that in case of future separations I get the child.
3. Do I make them file any other kinds of afidevits/docs?

My bottom line: My family values are based on justice, honesty, forgiveness and patriotism, we have Gandhian freedom fighters, Shorya Chakras, army officers and teachers while their family can't think anythying other than corruption, suspicion and revange - at least I know it by now and will fight to the last ounce of my resources before letting my daughter take their culture.

Somebody please show light urgently.
