As per the law, both should be Hindus while marrying
New Delhi – Inter-faith marriage is considered invalid as per the Hindu Marriage Act. This law permits only Hindus to marry, observed the Supreme Court (SC). After the filing of the complaint by a Hindu lady against her husband in 2017 in Telangana, the crime was registered against the husband as per the Indian Penal Code (IPC), Section 494. The Sections says that whoever, having a husband or wife living, marries in any case in which such marriage is void by reason of its taking place during the life of such husband or wife, shall be punished with imprisonment of either description for a term which may extend to seven years, and shall also be liable to fine.
