Thank You for the replies.
@Yentede Banta: I agree. Marriage is just a ritual. I too feel the same. But sadly the girl's family is hell-bent on that ritual which made me wonder the intention.
@SAINATH DEVALLA: I think I need to clarify the situation a bit more. Although there is no pressure from my side for the girl to convert, the girl's family was pursuading me to convert legally. On my family not agreeing, finally they gave in to Special Marriage Act but insist that there will be a Nikah just outside court in Kazi's office. They are assuring that there will be no legal conversion. Hence my question remains
1. Is special marriage act above all other methods of marriage (Nikaah)?
i.e. Even if we have a Nikah at Kazi's office, does the special marriage act become void after the Nikaah?
2. What is the legal standing of such a Nikaah? Will I, then legally be a Hindu or a Muslim?
Thank you for your inputs. But if you could just clear my confusion, I would be grateful.
