In which state should I apply for 498a anticipatory bail?

Hi all, please guide me. Should I apply for anticipatory bail for an expected false 498a case in the state of Karnataka where my wife and me reisde now or in Andhra where her parents are residing? If the Bangalore court grants me, my sister and brother inlaw and my parents anticipatory bail, can it prevent the arrest of my parents living in Vijayawada, if my wife chooses to go back there and file the case? My parents live in Vijayawada, Andhra PRADESH. Wife's parents live in Machilipatnam, Andhra pradesh. We got married in Machilipatnam and we both are currently staying in Bangalore now. We never lived in Vijayawada. My sister and her husband are currently living in Bangalore. My Wife is threatening to file a false 498a on me, my parents, my sister and brother in law. Am not sure whether she will file the case in Bangalore or go back to her parents in Andhra and file there. In which state should I apply for anticipatory bail for all of us? I, my sister and brother-in-law are in Bangalore and parents are in Andhra. Should I apply for anticipatory bails seperately for four of us as per our states of residence? Kindly advise.
