Hi, Let me tell you , I have a friend in Chandigarh and he is living in same status , 498A/Divorce case is pending , but he decided to move on in live in relationship with other girl , Infact 498A wife came to know about this from some Neighbours.
498A cried in court mentioning that he married to other girl , But she cant proof it even after having a voice recording of Neighbours.
But since he is into livein wiith unmarried girl , there are not adultery charges on him.
YES i 100% agree to shonee sir that if 2nd girl want she can screw your life very badly , if she want she can anytime file 376 Rape case ,But trust me having s*x with any girl /girl friend / prostitues is not safe because if girl file 376 , then there is no bail and such case runs in FAST TRACK and situation will be worst if girl is below 18 , ofcourse you are not moving in livein with below 18 girl.
So you need to be very carefull about the same
