I had the opportunity to go through the petition. It is neither here nor there. On the basis of this petition you both will not get the relief because it is beating the bush. Let me try to explain. A is a wife and B is husband. A can seek annulment of the marriage only on the ground that B is not in a position to consumate the marriage DUE TO IMPOTENCY. It is important to say in the petition that the phrase of impotency and also it should be attributed to B. (A cannot get annulment on the ground that she is impotent.) It is an independent ground and if B chooses not to appear in the court, on that ground itself exparte annulment decree can be passed. The after result of the annulment decree is that the husband B will be impotent forever in the eyes of law and his future matrimonial prospects will be severely affected. This impotency case falls under Section 12 (1)(a) and not 12 (1)(c).
Now, I revert to 12 (1)(c) A can file annulment petition but the ground should be that A has been forced for the marriage. If A alleges that B has been forced for marriage, she cannot have a right to file such a case and cannot get decree. Under Section 12 (1)(c) itself there is one more ground available i.e., fraudulent representation. If A alleges that on material facts B misrepresented for solemnization of marriage, then if B does not appear in the court exparty decree can be passed. For me it appears that you confused between forceful and fradulent marriage. In the case of former if A is forced, she has a right to file petition and if it is a fradulent marriage in respect of material fact, A can file petitin under S.12(1)(c), but she has to show strong proof that fraud in respect of material fact has been perpetrated against her. On the basis of the petition, it is very difficult for you to get annulment as it is obfuscating the facts.
My suggestion is that you can go for MCD. In the MCD both the parties simply mention that due to tempermental differences, that the marriage has not been consumated. On that basis six months after filing the petition both will get divorce. But for that one year separation has to be shown.
