Section-498- Enticing or taking away or detaining with criminal intent a married woman "Whoever takes or entices any woman who is and whom he knows or has reasons to believe to be the wife of any other man, from that man, or from any person having the care of her on behalf of that man, with intent that she may have illicit intercourse with any person or conceals or detains with that intent any such woman, shall be punished with imprisonment of either description for a term which may extend to two years, or with fine, or with both.
Ah the irony!!
Now If Rajdeep comes to know whatever is happening between Kunal and Nandini and is able to prove Kunal has other intentions, Kunal will be jailed but not Nandini since the Indian laws treat man as the abettor and woman as the victim.. But Rajdeep can use it to walk scot-free without paying Nandini alimony...
Although it doesn't happen in serials where characters are able to mysteriously circumvent set laws and live life as they wish, still lets see what happens...
