Child visitation

1. The residential address of your wife where she is staying without you is the proof of the child's residence.

2. you can file a petition before the H.C. to get such visitation rights.

If wife is asking for divorce, give it, and along with it give also the child and forget about it, it will cause you less pain to all people involved.  Vistation rights custody all will make entire thing very murky.  You yourselves will be surprised by the end of it are you humans or something else, just google Mr Kumble the great leg spinners case.  You will understand where all it can go and what all it can lead to.
