In which Section of the Hindu Marriage Act, 1955 is 'bigamy' prohibited ?

Section 17 of the Hindu Marriage Act provides that a marriage between two Hindus is void "if at the date of such marriage either party had a husband or wife living", and applies the penal provisions on bigamy.

Section 15 deals with when divorced persons may marry again, section 19 with the court to which a petition is presented, and section 21 with the application of the Code of Civil Procedure. Section 17 still refers to sections 494 and 495 of the Indian Penal Code; bigamy is now punished under section 82 of the Bharatiya Nyaya Sanhita, 2023.
