Husband has left India and hiding himself to avoid divorce

My cousin's husband (both Hindus) left for Canada a few weeks after their marriage in 2011. They were in contact through email and phone. But after a few weeks, my cousin moved to her parents' house because she knew that he would never return to India. In 2016, she filed a case against him. Alimony of 7000rs was fixed by the court. But she has not got a single paisa till date because the court says that they cannot recover this amount as he is not in India.The man is intentionally not giving his Canadian address to my cousin. But every now and then he keeps sending her vulgar and disrurbing whatsapp messages. Even he calls her occassionally and uses vulgar and abusive languages. nThe court has been informed about all this, but they say nothing can be done because he is abroad and she does not have his address.She is so frustrated and depressed, as that man is neither willing to pay allimony nor willing to give divorce.Kindly guide. Your help will be appreciated.
