Dear Shikharji,
Thanks for prompt reply. Please note, your marriage is not registered as such, a translation of the marriage contract has been authenticated by the embassy. Hindu religion does not contemplate of a marriage contract, therefore the relevance of the document you sent is only to the extent that it is a proof of the fact that you both were married as per Hindu religion.
It would be helpful to me, if you would mail a brief write about your self, your family background. about your wife, her family background circumstances in which marriage took place and the nature of evidence you have regarding her relationship/s.
Regards.
