498a , 125 crpc cases , loc notice

Sir, I am working Abroad . I got married in 2016 march.. my wife stayed with me for 45 days and got pregnant. then after she traveled to INDIA for medication. Now i am having 1yr 9 month old child, he was staying with his mother in India. Due to his father arrogant behavior and influence of his parents she rejected to come abroad. I tried all ways to convince to get her back, but it didn't workout. I collected all evidences (audio/Video records). now we are apart more than 2 years.. recently she filed 498A, DVC, 125CRPC, NBW(being abscond) against me. My Parents staying in INDIA , they were crossed 75+ and help less because of Old age factors. As of now i didn't take any proper action due to lack of knowledge(IPC sections). I heard that our India IPC section are in favor to females but still I have enough evidences. I tried arranging meeting with wife family but they rejecting to attend. Because of their cruel mind set, time is getting delayed and under going pressure times. I am clear about child custody. I am Ok with either of choice to take it or handover to me. Instead dragging I want to put this situation to END with the help of Advocate. My question how to approach it legal in either defensive and offensive ways?.. Please suggest..
