1.) This proof could only amount to your expectation but a rigid proof that you wanted only a MCA is required. Still in your case your wife is not even holding masters so you have a solid proof in hand.
2.) This proof would help you in addition to the proof in pt.1
3.) As I already suggested, try to draw evidence in the form of video or voice recording in which your wife or her parents are coercing you and threatening you for 498-aor similar fraud cases.
4.) You are lucky that the area of Jurisdiction would be Delhi for the case. A local court in Delhi only could hear this case and it cannot br tried in UP
5.) It's more good that you have no emotional bonding due to any child. It would be easier for you to part with the girl.
6.) The reason why she left the matrimonial home should be justified. If she cannot prove any coersion or cruelity by you then she is unjust in leaving you behind. A spouse is not supposed to desert the other without just case and if he/she does so, it becomes a clear groud of divorce. But for divorce in such circumstances a petition could only be moved after 2yrs of such desertion.
7.) You have to mention this point in your petition before the court. Then it would be the wife and her parents to show that you demanded dowry.
8.) It is also relevant point that you spent very less time with the girl.
With the above points I suggest the below steps:
a.) appoint a good advocate who has prior proven record in matrimonial cases. If you are in Delhi then I can suggest you one genuine and good advocate.
b.) file a petition for divorce in local court which hold the jurisdiction for your case. In your petition the groudn should clearly be the fraud. With this you can pray to the court to grant a decree to annul the marriage because of the fraud played on you.
c.) as this fraud as you mentioned may not be acceptabel alone, you should add the points as stated in above that when you inquired about the studies from your wife she threatened you and left the matrimonial house. And that now her parents are also threatening you of dire consequences and of false cases.
d.) this would be a private complaint so the judge of the court would decide to order a criminal trial or a mrtimonial case. The advocate whom you would hire should be able to get you out of this menace within 2yrs from now.
e.) last but not the least, file this petition as soon as possible. As otherwise if your wife files her false case then you would be in deep trouble.
All the best!
