Dear Querist
As per your queries my opinion is as under
1) While the case is under consideration at a UK court, can she go to India and file for a divorce there?
Opinion:- yes she can return to india and file divorce case here against you.
2) If we get a divorce here, can she go to an Indian court and apply for maintenence there?
Opinion:- yes she can file maintenance case in India.
3) Given the fact that she is able bodied and has a masters degree from India, is she likely to get any maintenence if she applies through an Indian court?
Opinion:- if she is unable to maintain herself and left your company with sufficient reason then she will be entitled to get maintenance otherwise not.
