Polygamy in India is outlawed. While polygamy was not prohibited in Ancient India and it was common among aristocrats and emperors, it is believed that it was not a major cultural practice. The lack of prohibition was in part due to the separation between land laws and religion (independence of the judiciary), and partially since all of the major religions of India portrayed polygamy in a neutral light.
In contrast to Europe, polygamy prevailed in ancient India for rulers and kings. It was common for rulers (for example Bhupinder Singh of Patiala and Fateh Singh of Udaipur and Mewar). Some wealthy individuals (for example Ramkrishna Dalmia, Gajanan Birla and P. Rajagopal) had multiple wives.
The British colonial Empire of India permitted Islamic provinces to allow husbands to have multiple wives. When Maharaja Ranjit Singh was cremated in Lahore, four of his wives and seven concubines took to Sati, and their urn-like memorials exist at his Samadhi.
Section 494 and 495 of the Indian Penal Code of 1860, prohibited polygamy for the Christians. In 1955, the Hindu Marriage Act was drafted, which prohibited marriage of a Hindu whose spouse was still living. Thus polygamy became illegal in India in 1956, uniformly for all of its citizens except for Muslims, who are permitted to have four wives and for Hindus in Goa and along the western coast where bigamy is legal.
A polygamous Hindu marriage is null and void. While the punishment specified in Sections 494 and 495 is applicable, it is rare if the first spouse does not have an objection.
Muslims in the rest of the country are subject to the terms of The Muslim Personal Law (Shariat) Application Act of 1937, interpreted by the All India Muslim Personal Law Board.
However, in a judgment in February 2015, the Supreme court of India stated that "Polygamy was not an integral or fundamental part of the Muslim religion, and monogamy was a reform within the power of the State under Article 25".
The Bollywood star and Lok Sabha member Dharmendra was already married to Prakash Kaur when he married actress Hema Malini in 1980. While it was reported that he had converted to Islam for the sake of the marriage, he denied getting converted.
Legally the second wife of a Hindu would be a mistress, although religiously and socially she may be considered a wife.
Polygamy among Hindus is sometimes accepted in some rural areas, often with approval by earlier wives. The 2005-06 National Family Health Survey (NFHS-3) found that 2 percent of women reported that their husband had other wives besides herself. Husbands of women with no children are more likely to have multiple wives.
Chand is a social drama film dealing with the story of a childless couple with Balraj Sahni and Meena Kumari in lead roles. Mr. Kapoor (Balraj Sahni) who is a married to Kamla (Pandari Bai) cannot have a child of their own. Kamla wants a child but under duress agrees to have Mr. Kapoor take a second wife and have a child. Sahni marries Vimla (Meena Kumari) with a heavy up front payment to her father. The marriage just collapses shortly after when Meena Kumari finds herself with another wife competing for the same husband. She gives birth to a child but leaves her husbands house to live with her father as it was evident that she was losing her senses in the situation she was thrown in. As she recovers her senses at her father's place she wants her child back but both Kamla and Mr. Kapoor declines to give the child back. The issue goes to court but the court decides against Vimla and she goes mad. Watch the rest of it to see how matters end happily and both Vimla and Kamla decides to live peacefully with the same husband. Even though the movie was released in the year 1959, the film was based in the year 1955, before the abolishing of polygamy.
In Mizoram state, a Christian religious sect known as "Pu Chana Páwl" or simply "Chana," formed in June 1942, permits polygamy. As of 2011 its leader, Ziona (born 1945), had 39 wives, 94 children, and 33 grandchildren, all living under one roof.
