Thank you for your response. Did you have to take any specific documents when you went to the municipal corp? Also, what exactly is the municipal corp? We got married in Meerut, UP. Also, I have returned back to Canada. Do I need to be physically present with my wife in order to get this certificate?
The both of you do not need to be present. Your wife can go to get it herself. But they will need the nikah Nama, your passport size photos as well as passport copy to prove that you are the husband and she will also need the same documents to prove that you are both the people who got married. It takes a few days to a week. And I am not sure if you have to pay fees or not. I m not sure what the municipal corp is either.
Sorry, I can't be of more help... I m not completely sure of the process but this is what I remember from applying for this document 9 months ago. Good luck.
