i married a girl who got divorced from her ex (nri) in u.s.a thru mutual consent (she was respondent)but her hubby had marriage registered in u.s.a with other girl.he had married to that girl without divorcing my wife.is the divorce decree from u.s.a with my wife is valid (mutual consent). or can it be held invalid due to loop holes in it(loop hole being that boy already married and registered in u.s.a didnt declared to u.s. court and took div from my wifein u.s.a).
