Divorce

First of all to register a complaint in nearest police station where you lived with your wife last from where your parents in law took her away. Register a complaint stating that your parents in law are continuously interefering in your marriage life and putting pressure on you they have taken her away from your matrimonial house against your consent. Take a copy of that FIR with you for your reference and produce it in maintenance case if she files in future

Rahul is right but after one year atleast you can go for divorce not before

Ek bechara phir gaya mara!! pardon to start from lighter angle.

Neways, now it appears that it is getting really complicated and you are scared but don't worry play this battle step by step, smartly and strategically as your unreasonable wife is armed with very destructive armory... 

FIRST OF ALL TRY TO MEET THE MEDIATOR (ONE WHO WAS INSTRUMENTAL IN GEETING THIS MARRIAGE ARRANGED), SET A COMMON PLACE FOR MEETING B/W YOUR FAMILY AND GIRL'S FAMILY. SOUGHT OUT THE THINGS AND REACH TO COMMON  CONCLUSION, agar baat nahin banti then fight it out legally;

 

1. If, possible register an FIR against your father-in-law  and his some other relative alleging taking your wife without your permission and demanding 2-3 lakhs rupees by blackmailing to register case under 498A and dowry prohibition act.

2.file habeus corpus writ  in High Court immediately. We know she will not come but it will help in any further proceeding initiated by her.

3. Get a separate resident proof from your family members and relatives. I mean it should be evident that  you and your wife were living separately from your family.
