Are working women eligible for compensation ?

My sister got married almost 3 years ago to an NRI near chennai, he had said before marriage that he didn't want anything as dowry and he had promised to take her to US but he left her in India within a week and later he made his intentions clear that our dad had to give his mother and sister a hefty amount and gold as dowry or he won't live with her.He is also boasting that many were standing in a line with dowry to get married to him and what his family demanded was nothing.When my father refused to accept the demand he started pestering my sister for divorce but she refused to give it to him then he started threatening her with stalking by his relatives and friends and started making false claims that my sister was going out with her colleague,then we lodged a police complaint against him and his family for stalking.Police warned his family to stop stalking her or call her over the phone .Now, he has sent a legal notice claiming that he wants to divorce her because she was not interested in living with him and she didnot respect his parents.Now after all this She is really not interested in living with him as he seems hostile but she wants to recover the money that was spent on the wedding and invest it for her future and quit her job as the depression caused by his criminal act has taken a toll on her health and eyesight . He seems to be in a hurry now.He is literally begging her to give divorce but my sister is not ready to take all the financial and social damages caused to her by this marriage.And we also suspect that his sister's are preparing for his second marriage. Note: his family members are still spreading false news about her among our relatives and friends.We are not able to answer anyone.
