Bigamy is the practice of being married to two people at once. This form of marriage is considered as illegal As a general rule, bigamy is rarely prosecuted, and when it is, the penalty varies; the primary spouse may be ordered to serve time in jail, and potentially to pay a fine, for example.
In a classic example of bigamy, a man marries a woman, and then marries another several years later, while he is still legally married to the first women. Depending on the culture in which the bigamy occurs, the second marriage may be undertaken with the full consent of both wives, or the second marriage may be concealed.
ACCORDING TO SECTION 494 OF THE INDIAN PENAL CODE, ‘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.
