494 vs 82

IPC 494 (bigamy) and IPC 495 (bigamy with concealment) are merged into a single BNS Section 82 with tiered punishment: 7 years for standard bigamy and 10 years when the prior marriage is concealed. The Sarla Mudgal principle — conversion to Islam does not erase criminal liability — continues to apply.

What Changed?

IPC had two separate sections: 494 (standard bigamy — 7 years) and 495 (bigamy with concealment of first marriage — 10 years). BNS merges both into Section 82 with a single tiered structure.

Punishment tiers preserved: BNS 82 provides 7 years for marrying while a prior valid subsisting marriage exists, and 10 years if the accused concealed the prior marriage from the second spouse.

The Sarla Mudgal principle continues: a Hindu man who converts to Islam to contract a second marriage remains criminally liable for bigamy under BNS 82 — the first Hindu marriage is not invalidated by religious conversion.

Muslim men married under personal law (not Special Marriage Act) continue to be exempt from bigamy prosecution for up to 4 wives — unchanged under BNS.

Bigamy remains Bailable under BNS 82 — magistrate has discretion to grant bail. Non-Cognizable — police cannot arrest without warrant or magistrate's order.

Void marriage exception preserved: if the first marriage is void ab initio (e.g., within prohibited degrees), a second marriage does not attract Section 82.

Verdict

"BNS 82 streamlines the bigamy framework into one section while increasing the concealment penalty from 10 years (IPC 495) to a clear statutory tier. The merger eliminates the need to charge two separate sections, simplifying FIR drafting. The Muslim polygamy exception and the Sarla Mudgal anti-conversion principle remain fully operative."

Legal Implications

IPC 494/BNS 82 targets one of the oldest marriage frauds — marrying again while a legally valid prior marriage subsists. The offence has three essential elements: (1) the accused was previously married; (2) that marriage is still legally subsisting (not dissolved by divorce or death of spouse); and (3) the accused contracts another marriage. The critical legal principle is that the first marriage must be valid and subsisting at the time of the second marriage. A divorce decree, annulment, or the death of the first spouse before the second marriage are complete defences. The most significant case interpreting Section 494 is Sarla Mudgal v. Union of India (1995), where the Supreme Court addressed the specific tactic of Hindu husbands converting to Islam solely to exploit Islamic personal law's polygamy permission. The Court held emphatically that religious conversion does not retrospectively void the first Hindu marriage — the first marriage remains a valid Hindu marriage for criminal law purposes, and the second marriage therefore attracts Section 494. The Court further observed that the use of personal law pluralism to commit bigamy was a violation of constitutional equality. BNS 82 consolidates IPC 494 and 495 into a single tiered provision, removing the drafting burden of charging two separate sections while preserving the escalated penalty for fraudulent concealment. The concealment aggravation is particularly important where the second spouse is an innocent victim who was deceived into the marriage.

Practical Scenarios

"A Hindu man marries in 1990, is separated (but not legally divorced), and remarries in 2010 without obtaining a divorce decree — prosecuted under BNS 82 (7 years)."

"A man conceals his first marriage and presents forged divorce papers to his second wife — BNS 82 enhanced tier (10 years)."

"A Hindu man converts to Islam and immediately contracts a second marriage — Sarla Mudgal applies; criminal liability under BNS 82 survives."

"A man whose first wife died in 2015 remarries in 2020 — no offence; the first marriage no longer subsists."

"A couple married under the Special Marriage Act; the husband converts to Islam — the Special Marriage Act governs, not personal law; bigamy prosecution applies."

Expert Q&A

What is the BNS equivalent of IPC 494 (Bigamy)?

IPC Section 494 (and IPC 495 for bigamy with concealment) are now BNS Section 82. The provisions are merged into one tiered section: 7 years for standard bigamy and 10 years if the prior marriage was concealed from the second spouse.

Is bigamy bailable in India?

Yes — bigamy under BNS 82 and IPC 494 is a Bailable offence. This means the accused can seek bail as a matter of right from the police or magistrate. The offence is also Non-Cognizable — police cannot arrest without a warrant.

Can a man escape bigamy by converting to Islam?

No. The Supreme Court in Sarla Mudgal v. Union of India (1995) and Lily Thomas v. Union of India (2000) held that a Hindu husband who converts to Islam to contract a second marriage remains criminally liable under Section 494/BNS 82. The first Hindu marriage continues to subsist for criminal law purposes and is not dissolved by the conversion.

Does bigamy law apply to Muslims in India?

For Muslim men married under Muslim personal law (not Special Marriage Act), Islamic personal law permits up to four wives, so Section 494/BNS 82 typically does not apply to a Muslim man's additional marriages. However, if a Muslim man married under the Special Marriage Act, his marriage is governed by that Act and bigamy law applies. Muslim women cannot marry again while their first marriage subsists.

What is the difference between Section 494 and Section 495 / BNS 82 tiers?

Section 494 (BNS 82 basic tier): marrying while a prior valid marriage subsists — up to 7 years. Section 495 (BNS 82 enhanced tier): same offence BUT the accused CONCEALED the prior marriage from the second spouse — up to 10 years. If the second spouse already knew of the first marriage, the concealment element fails and only the basic tier applies.

What happens if the first marriage was void — does bigamy still apply?

The first marriage must be valid and subsisting for bigamy to apply. If the first marriage was void ab initio (prohibited degrees of relationship, lack of age, prior subsisting marriage), it is as if it never existed — a second marriage does not attract Section 494/BNS 82. Courts assess the validity of the first marriage as a preliminary question.

Can a wife file a bigamy complaint against her husband?

Yes — the first wife is the primary aggrieved person and can file a complaint. Because bigamy is Non-Cognizable, the first wife must approach a magistrate under Section 190 CrPC (now BNSS equivalent) with a private complaint. Police cannot register an FIR directly without a magistrate's order.

Does legal separation (not divorce) allow a second marriage?

No. A legal separation is not a dissolution of marriage — the first marriage continues to legally subsist. Only a formal divorce decree, court annulment, or the death of the first spouse dissolves the first marriage and permits remarriage without attracting bigamy provisions.
