Plz clarify me about the Correct jurisdiction of the case.

Can I file this new case in delhi district court as child (SON) is now staying in delhi with his grand parents.I (father) am staying in Andhrapradesh beacuse of my transferable job.

Hi Gaurav, I'm Adv. Niharika and here is my take.

according to sec 9(1) of Guardianship and Wards Act, a petition for custody of the child is to be filed at the court in whose jurisdiction the child usually resides. It is important to note, that the term used is "usually" and not "permanently". As in your case, your child is now residing with his grandparents in Delhi, then you can most certainly file an application for custody in Delhi.
