Bigamy can i quash to remove my parent, my 2nd husband's name, and my husband's parents from fir

You are in hurry to detail the query- the  second husband is Indian ? His parents are staying in India?

if you married while already having a husband then you and your husband can be prosecuted for bigamy, but your parents or your husband's parents simply can excuse themselves from all this tantarum- they cannot be held held laible except if they knwoingly helped to commit the crime.

SImply let them file writ petition to qush FIR against them in high court..

I and 2nd husband in USA

my parents and his parents in india

Yes, they can move a petition for discharge or approach the High Court under Section 482 CrPC.

get a good lawyer and quash the FIR against your parents, otherwise also they have nothing to do with what you did. meanwhile you should apply for divorce there and get your first marraige decreed as obsolete.
