My son & daughter in law were green card holders in USA. My son applied for divorce and she responded by filing a notice of appearance and written statement therein stating that she "also wants a divorce dissolving all bonds of matrimony." Thereafter she came to India to file false cases. Her lawyer there continued to represent her till the end. Due procedure was followed and after getting replies to Discovery & Inspection queries, a divorce decree was obtained on the ground of "mental cruelty and inhuman treatment by wife to husband." In the last hearing her attorney stated that the US court had no jurisdiction as the marriage was solemnised in India.This decree has been challenged by her in a Kolkata civil court. Can we in response say that the local court has no jurisdiction to try her plaint as both parties were domiciled there, followed due process after submitting to their jurisdiction and divorce was obtained on a ground available in India? Is there a citation that we can quote?
