Three fresh judicial rulings — two from 2026 alone — have significantly sharpened what Indian matrimonial law says about a husband’s second marriage and who can be held legally responsible for it. If your husband has contracted a second marriage while your marriage remains legally undissolved, this article gives you the complete and current picture: what the law says, what you can do, who you can file against, and what the courts will and will not support.

1. The Legal Foundation: A Second Marriage Without Divorce Is Void and Criminal

This starting point has not changed, but the statutory language has.

Under the Bharatiya Nyaya Sanhita (BNS), 2023 — the code that replaced the Indian Penal Code on July 1, 2024 — the law on bigamy now sits in Section 82.

• Section 82(1) BNS: Marrying a second time while the first spouse is alive and the first marriage remains legally valid and undissolved is punishable with imprisonment up to seven years, fine, or both.
• Section 82(2) BNS: If the husband concealed the existence of the first marriage from the second woman — deceiving her into the relationship — the punishment increases to up to ten years. Under the BNS, this aggravated form has also been made non-compoundable (cannot be settled by private compromise once the complaint is filed). This is a significant tightening of the law compared to the position under the old IPC.

The second marriage itself is void ab initio — it does not legally exist. It confers no rights on the second woman as a legal wife, and no obligations arise under it that can override the first wife’s rights.

One important procedural point that many people miss: bigamy under Section 82(1) BNS is non-cognizable. Police cannot arrest the husband directly on your complaint alone. You must file a private complaint before a Judicial Magistrate First Class (JMFC) under Section 223 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023. The magistrate issues summons after examining the complaint. This is a different process from a 498A complaint (which is cognizable). Understanding this distinction upfront avoids false starts.

2. What the Supreme Court Said in April 2026: In-Laws Are Not Automatically

Liable

The most practically significant 2026 development on bigamy came from the Supreme Court on April 24, 2026, in Sivaraman Nair and Others v. State of Kerala and Another (2026 INSC 412).

The case arose from a matrimonial complaint in which a wife alleged that her husband had contracted a second marriage and that his parents and siblings — the in-laws — had been aware of it, had supported it, and had participated in dowry harassment and cruelty against her. She named them all as co-accused.

A bench of Justice Sanjay Karol and Justice Augustine George Masih quashed the proceedings against the in-laws entirely.

The Court’s reasoning is precise and important for how any bigamy complaint in Delhi is drafted going forward:

Criminal liability cannot be imposed on a person solely because they are related to the person who committed the act. To prosecute in-laws for bigamy, there must be specific, identifiable evidence that they actively participated in arranging, facilitating, or instigating the second marriage. Knowing that it happened — even being present at the second wedding in a general capacity — is not enough. General allegations that they “knew and approved” without attributing specific acts to specific people on specific occasions are insufficient.

The Court also noted two factors that weakened this particular complaint: the allegations against the in-laws were generic rather than specific, and there was a six-year unexplained delay between the alleged incidents (2007–2010) and the filing of the FIR in 2016. Delay does not destroy a bigamy complaint, but unexplained delay combined with vague allegations creates a vulnerability that opposing counsel will exploit at the quashing stage.

What this means for drafting your complaint:

If your father-in-law presided over the wedding rituals of the second marriage, name him and describe his specific role. If your sister-in-law made the arrangements, describe what she specifically did and when. If your mother-in-law received jewellery for the second bride or hosted the ceremony, that is a specific act. But “they all knew and they all supported it” — without those specifics — will not survive a quashing petition in the Delhi High Court.

3. What the Karnataka High Court Said in March 2026: Living With Another Woman

Is Not Bigamy

A ruling from the Karnataka High Court, delivered March 3, 2026, and which has since circulated widely in practitioner commentary, clarified the boundary that confuses many clients: a husband’s live-in relationship with another woman is not bigamy.

The facts: a wife filed a private complaint alleging that her husband was living with a 51-year-old woman “like husband and wife.” The magistrate took cognizance and tried all four accused (husband, partner, and their two adult sons) for bigamy. The Karnataka HC quashed the entire proceedings.

The Court’s reasoning was based on first principles: bigamy punishes only the solemnisation of a second marriage with valid legal rites. A live-in relationship — however long, however open, however widely known, however emotionally committed — does not constitute a marriage for the purposes of Section 82 BNS. There is no second marriage to prosecute without proof of actual marriage rites.

This matters in practice because a large number of husbands in this situation are in live-in relationships rather than formally solemnised second marriages — precisely because they know the legal risk. If your husband is living with another woman but has not solemnised a second marriage, your criminal remedy is not a bigamy complaint. Your civil remedies — divorce on cruelty grounds, maintenance, and domestic violence proceedings if the conduct has caused you harm — remain fully available and are often more effective in practice.

The 2024 Supreme Court addition: A May 2024 Supreme Court ruling (which continues to govern proof in 2026) confirmed that to convict for bigamy, the prosecution must independently prove all three elements: that a valid first marriage existed; that the first spouse was alive at the time of the second marriage; and that the second marriage was actually solemnised with valid religious rites and ceremonies — for Hindus, this typically means saptapadi (seven circles around the fire) must be established. A bare confession by the husband is not enough. This is the evidentiary bar you need to meet.

4. The Second Wife’s Rights: What a 2025 Supreme Court Ruling Changed

In 2025, the Supreme Court issued a ruling in Sukhdev Singh v. Sukhbir Kaur that expanded the rights of a second wife even in a void bigamous marriage.

The Court held that a spouse in a void marriage can claim permanent maintenance under Section 25 of the Hindu Marriage Act — and explicitly stated that “the right to maintenance does not depend on the morality of the bigamous marriage.”

This matters in two directions.

For the second wife who was deceived — who married the husband genuinely not knowing about the first marriage — she has real legal remedies. She can file under Section 82(2) BNS for the aggravated bigamy offence (up to ten years), claim maintenance under Section 25 HMA, and seek residence protection under the Domestic Violence Act if she cohabited with the husband in that capacity.

For the first wife — this ruling means that even where a second wife enters the picture, the first wife’s exclusive inheritance and succession rights as the legal spouse are not affected. Children born of the second (void) marriage are treated as legitimate under Section 16 HMA and have inheritance rights from the father. But the second woman herself is not a legal heir to the husband’s estate. The first wife retains that status.

5. Your Complete Legal Toolkit as the First Wife

Route A — File a Divorce Petition Immediately

Section 13(2)(ii) of the Hindu Marriage Act gives every wife a specific, named statutory ground for divorce where the husband has contracted a second marriage after the solemnisation of the first. This is a defined entitlement — not discretionary relief. The family court does not need to weigh fault; the husband’s bigamy is itself the ground.

File for contested divorce on this ground from the outset. Include an application for interim maintenance under Section 24 HMA simultaneously, so financial protection begins running while the divorce proceeds.

Route B — File the Bigamy Complaint Before a Magistrate

Prepare a specific, factually detailed private complaint before a JMFC. Every allegation against every person you name — your husband and, if applicable, specific family members with specific roles — must be grounded in facts, not general characterisation. The lesson from Sivaraman Nair is that generality gets quashed.

Your evidence for the complaint should include: photographs from the second wedding ceremony; invitation cards; social media posts from the event; witnesses who attended; religious ceremony records (if the priest can be identified); and any documents — bank transactions, wedding registration records, correspondence — that acknowledge the second marriage.

Route C — File Under the Domestic Violence Act

If the discovery of the second marriage was accompanied by any cruelty — emotional, financial, or physical — or if you are at risk of being thrown out of the matrimonial home, a Domestic Violence Act complaint gives you immediate interim protection: a protection order, a residence order (you cannot be evicted without a court order), and monetary relief equivalent to what you need. Interim DV orders can be obtained in days or weeks rather than months. This route can run simultaneously with the divorce and the bigamy complaint.

Route D — Claim Your Stridhan

If jewellery, gifts, or personal property of yours remains in the matrimonial home or with the husband’s family, this is the moment to formally claim it. We covered stridhan recovery in our recent article on stridhan law — the right to recover stridhan is absolute, independent of the divorce proceedings, and not extinguished by the husband’s remarriage. Send a formal legal notice demanding itemised return, and file accordingly if the demand is refused.

Route E — Protect Your Children

If you have children from this marriage, file for interim custody and child maintenance simultaneously with the divorce petition. A husband who has contracted a second marriage and abandoned the first family faces a significant welfare assessment in custody proceedings — courts look closely at which parent’s conduct reflects genuine concern for stability and the children’s day-to-day welfare.

6. The Most Common Mistakes to Avoid

Filing a vague complaint against everyone you can name. The Sivaraman Nair ruling (April 2026) confirms that vague, omnibus allegations against in-laws will be quashed. A quashing petition that succeeds damages your overall position and emboldens the other side. Draft specifically or not at all.

Assuming a live-in relationship constitutes bigamy. After the Karnataka HC’s March 2026 ruling, this error is well-documented and well-known to opposing counsel. If there is no solemnised second marriage, build your strategy around cruelty, DV, and maintenance — not bigamy.

Waiting too long. The Sivaraman Nair Court specifically noted a six-year delay between the incidents and the FIR as a factor weakening the complaint. If you know about the second marriage and are collecting evidence, consult a lawyer about the timing of the complaint before that delay becomes an issue.

Treating the criminal complaint as the only or primary strategy. The bigamy complaint creates pressure, but it is the divorce and maintenance proceedings that secure your financial and legal position most reliably and most quickly. Don’t hold back the civil remedies while waiting for the criminal case to move.

Frequently Asked Questions

Q1. My husband has married again. Is that a crime in India?

Yes, for Hindus, Sikhs, Jains, Buddhists, Christians, and Parsis. Under Section 82 of the BNS 2023, a second marriage contracted while the first marriage is undissolved and the first spouse is alive is void, and the husband can be imprisoned for up to seven years. If he concealed your existence from the second woman, the punishment is up to ten years — and under the BNS, this aggravated form is non-compoundable.

Q2. Can I go to the police directly and file an FIR for bigamy?

No. Bigamy under Section 82(1) BNS is non-cognizable — police cannot register an FIR and arrest directly on your complaint. You must file a private complaint before a Judicial Magistrate First Class (JMFC) under Section 223 BNSS. The magistrate then examines the complaint and may issue a summons. This is different from a 498A complaint and requires a carefully drafted, evidence- supported complaint document.

Q3. Can I file against my mother-in-law and sister-in-law as well?

Only if you have specific evidence of their active role in arranging or facilitating the second marriage. The Supreme Court ruled in Sivaraman Nair v. State of Kerala (2026 INSC 412, April 2026) that mere knowledge of the second marriage — even attendance at the event — is insufficient to sustain a prosecution against relatives. You need specific acts, specific occasions, and specific evidence for each person you name.

Q4. My husband is living with another woman but there was no formal wedding. Is that bigamy?

No. The Karnataka High Court confirmed in March 2026 that a live-in relationship does not constitute a second marriage for bigamy purposes. Bigamy requires proof of a validly solemnised second marriage with proper religious rites. Your remedies in this situation are divorce on cruelty grounds, maintenance, and DV Act proceedings — not a bigamy complaint.

Q5. What proof do I need to establish that a second marriage took place?

You must prove three things: that your first marriage was valid; that you were alive at the time of the second marriage; and that the second marriage was actually solemnised with valid religious rites and ceremonies. For Hindus, this typically means establishing that the saptapadi took place. A confession by the husband alone is insufficient (confirmed by the Supreme Court in 2024). Useful evidence includes wedding photographs, invitation cards, videos, priest records, witnesses, and social media posts from the event.

Q6. Does my husband’s second marriage automatically give me the right to divorce?

Yes, directly. Section 13(2)(ii) of the Hindu Marriage Act specifically gives a wife the right to seek divorce on the ground that her husband has contracted a second marriage during the subsistence of the first. This is a defined statutory entitlement, not discretionary relief. You do not need to prove cruelty or desertion alongside it — the bigamy is itself the divorce ground.

Q7. The second wife says she didn’t know about me. What are her rights?

A deceived second wife has real remedies. She can file under Section 82(2) BNS (the aggravated form of bigamy, up to ten years, for concealment). She can claim permanent maintenance under Section 25 HMA — the Supreme Court held in Sukhdev Singh v. Sukhbir Kaur (2025) that maintenance rights do not depend on the morality of a bigamous marriage. And she can claim DV Act protections if she cohabited with the husband. However, she is not your husband’s legal heir and cannot inherit his property as a spouse.

Q8. Can I get maintenance from my husband while the bigamy case is pending?

Yes. Maintenance proceedings are independent of and run simultaneously with the bigamy complaint and the divorce petition. File for interim maintenance under Section 24 HMA as part of your divorce petition, and separately under Section 144 BNSS if needed. Your husband’s bigamy — and the conduct surrounding it — is a factor courts weigh in maintenance determinations, not a ground for reducing his obligation.

Q9. I was thrown out of the matrimonial home when I found out about the second marriage. What do I do first?

File a Domestic Violence Act complaint immediately — this is the fastest route to a residence order (preventing your illegal eviction) and interim monetary relief, which can be obtained in days or weeks. The DV Act complaint runs alongside your divorce petition and the bigamy complaint. Do not wait for the divorce to be filed before seeking residence protection.

Q10. How long does a bigamy case typically take in Delhi, and is it worth filing?

A private complaint before a JMFC can take anywhere from several months to a few years through summons, framing of charges, trial, and verdict. The value of the bigamy complaint is as much strategic — creating criminal pressure that influences settlement negotiations, maintenance hearings, and the other side’s conduct — as it is in producing a conviction. Combined with a well-structured civil strategy (divorce + maintenance + DV Act), it is an effective component of a coordinated approach. Whether it is worth filing as your first priority, or as a supporting measure alongside civil proceedings, depends on your specific facts — which a matrimonial lawyer can assess in a first consultation.
