My Sister in law has filed 498A and divorce 4 yrs back against my brother in law. She also involve me, my wife along with my father-in-law and mother-in-law. Now 498A has gone for hearing but she is reluctant to appear and missed 2-3 witness dates. I need to travel to US for 1-2 yrs due to my office work. What can be done so that I can travel with my wife and my kid.
