Uff oh !
1. I suggest you once again pay attention to the reply especially the words I used "skills of her petition writer". Very cleverly her lawyer has drafted her reply to misguide the court by using word “virgin” but now it all depend how your lawyer pushes your case on ‘fraud” in marriage.
2. Her petition writer has skillfully used interchangeable word "virgin" to confuse you that is why inspite a clear reply by me you came to me again with a statement "I can prove she was not a virgin"! How can now you prove if you consumated your marriage with her and otherwise if you have not consumated your marriage with her then also what is need to prove since "virgin for a bride" has never been grounds to marry or divorce!!!!! I mean for what on earth you need to prove her "virginity" when you say you have her earlier divorce papers based on whose (that she was un-married before her marriage with you is what you thought) facts hiding to you, your consent to marriage was taken and now since you came to know about it, you are seeking your marriage with her to be annulled on grounds of fraud and your first query reading before us is just that? Think now off her false virgin status for Gods sake!
3. All you have to prove is that, the consent to the marriage contract was obtained either by fraud or force, then there are grounds for an annulment exists as you say and read your first query facts. "Fraud" is simply not telling the truth in order to "induce" the other party to enter into the "marriage" contract. Whether the failure to tell the truth will be grounds for annulment depends of the facts of the case. "Facts" as in your query are that you thought she is un-married when marriage proposal were discussed that is why you entered into a marriage contract with her later. Had you knew before your marriage that she was earlier married and has a legal divorce probably your consent to marriage would have not been obtained, that is your case not "I can prove she was not a virgin" for seeking relief under "annulment of your marriage due to fraud or force ground". 'Force' does not apply to the best of my reading down your query in your case.
4. To get now your marriage annulled, you first need to meet the residency requirements of the State that they live in. The "jurisdictional" requirements are similar to those required for "dissolution or divorce" i.e. one of the parties must live in the State where the marriage annulment is filed for a continuous 90 days period. Like similar to a divorce filing, marriage annulment case proceeds with a petition filing, admission hearing, issues of summons, and ancillary documents (her earlier divorce decree certified papers you claim you have are annexures therein to prove your case) that is all.
5. In LCI there is no shortage of seasoned Advocates, search its database and get one appointed after due diligence. You will save on your "virgin" thinking greatly is my last reply on your query.
Lastly welcome to the great Indian thinking "virgin for a bride" from cradle to grave obsession of Indian males still living in their medieval mindset.
