Under the Bharatiya Nyaya Sanhita, 2023, a person commits the offence under section 84 if he

Section 84 of the Bharatiya Nyaya Sanhita, 2023 punishes whoever takes or entices away any woman who is, and whom he knows or has reason to believe to be, the wife of any other man, with intent that she may have illicit intercourse with any person, or conceals or detains any such woman with that intent.

Sexual intercourse with another man's wife without her husband's consent or connivance described adultery (formerly s.497 IPC), which is not an offence under the BNS after Joseph Shine v. Union of India (2018). Marrying again during the lifetime of a spouse is punished by section 82, and deceitfully inducing a woman to believe that she is lawfully married and to cohabit is punished by section 81.
