I receive this call more often than I would like.

A wife — sometimes in shock, sometimes in cold, quiet anger — tells me that her husband has taken a second wife. Sometimes she found out through photographs. Sometimes a mutual friend told her. Sometimes she was served with a divorce notice and realised, reading between the lines, that the next woman was already waiting.

She wants to know two things. First: what can she do? Second: can she file against his parents and siblings, who she believes knew about this and did nothing to stop it?

The second question has a clear new answer from the Supreme Court, delivered on April 24, 2026. The first question has several answers, none of which are as simple as people hope — but all of which are real and usable.

This article gives you both.

1. The Legal Position: A Second Marriage Without Divorce Is a Crime in India

Let me start with the foundational rule, because it is worth stating clearly.

Under Indian law — specifically for Hindus, Sikhs, Jains, Buddhists, Christians, and Parsis — a second marriage contracted while the first spouse is alive and the first marriage has not been legally dissolved is void. It does not exist in the eyes of the law. And beyond being void, it is a criminal offence.

The relevant provision today is Section 82 of the Bharatiya Nyaya Sanhita (BNS), 2023, which replaced the old Section 494 of the Indian Penal Code. Under Section 82(1), marrying a second time while a previous marriage subsists is punishable with imprisonment up to seven years, a fine, or both. If your husband concealed the fact of your first marriage from the second woman — deceiving her into the relationship — the punishment under Section 82(2) increases to up to ten years.

A few things to understand about how this works practically:

Bigamy is non-cognizable. This means the police cannot arrest your husband directly based 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 then examines the complaint and decides whether to issue a summons. This is different from, say, a 498A complaint, where arrest can follow FIR registration. Many wives are surprised by this distinction — it means moving faster in court, not at the police station, is usually the right approach.

You need proof of a valid second marriage. This is where many bigamy cases actually struggle. Courts require evidence that the second marriage was performed with the proper religious rites — for Hindus, that typically means the saptapadi (seven circles around the fire) must have taken place. A live-in relationship, however long or however widely known, is not a marriage for the purpose of bigamy law. The Supreme Court has consistently held this, and the Karnataka High Court reaffirmed it as recently as March 2026, in a case where a wife tried to file bigamy against her husband who was cohabiting with another woman. The court quashed the complaint entirely on the basis that cohabitation, without proof of valid solemnization, does not make out the offence.

This does not mean you are without options if your husband is in a live-in relationship rather than a formally solemnized second marriage — it means you need different remedies for that situation, and your divorce lawyer needs to advise you on the right route.

2. What the Supreme Court Just Said About In-Laws and Bigamy (April 2026)

Here is the ruling that every wife filing — or thinking of filing — a matrimonial complaint needs to understand before she decides who to name as accused.

In Sivaraman Nair and Others v. State of Kerala and Another (2026 INSC 412), decided April 24, 2026, the Supreme Court was examining a criminal complaint filed by a wife who alleged that her husband had contracted a second marriage. In the same complaint, she had named his parents and siblings — the in-laws — as co-accused, alleging that they had been aware of the second marriage, had supported it, and had participated in dowry harassment and cruelty against her.

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

The Court’s reasoning was tight and important: criminal liability cannot be imposed on a person solely because they are related to the person who committed the act. For in-laws to be prosecuted for bigamy, there must be specific, identifiable evidence that they actively participated in arranging or facilitating the second marriage, or that they specifically encouraged or instigated it. Knowing that it happened is not enough. Being present at the second wedding is not automatically enough. General allegations that they “supported” or “encouraged” the husband’s conduct, without specific acts on specific occasions, are not enough.

The Court also noted two additional factors that weakened the case in this specific matter: the allegations against the in-laws were, on examination, generic rather than specific — the complaint did not attribute any particular act of dowry demand, threat, or physical assault to them on any identifiable occasion. And there had been a significant and unexplained delay between the alleged incidents (2007–2010) and the filing of the FIR in 2016, which the Court viewed as casting doubt on the genuineness of including the relatives at that stage.

The Court relied on its 2024 decision in S. Nitheen and Others v. State of Kerala and Another and confirmed that this is not a new rule — it is a longstanding principle of criminal jurisprudence being applied consistently. The 2026 ruling simply makes the position undeniably clear in the specific context of bigamy.

3. What This Means for You Practically

I want to be straightforward with you about what this ruling means and does not mean.

What it means: If you are planning to file a criminal complaint naming your in-laws as co-accused for your husband’s second marriage, the complaint must contain specific, verifiable allegations about what each of them personally did — not a general assertion that they knew and approved. If the only allegation against the mother-in-law is that she attended the second wedding, that is not enough. If the allegation against the father-in-law is that he was aware and did nothing to stop it, that is not enough.

What it does not mean: It does not mean in-laws can never be prosecuted. If you have specific evidence — photographs of the father-in-law performing a role in the wedding rituals, messages from the sister-in-law actively arranging the function, proof that the mother-in-law received or distributed the second wife’s jewellery — those are specific acts that may support a separate charge of abetment. The ruling does not protect active participants; it protects people who are being named solely because of their relationship to the husband.

Practically: This ruling should inform how your complaint is drafted, not whether it is filed at all. The answer is not to abandon the case — it is to file a complaint that is specific, factually grounded, and focuses your criminal remedy on the husband (who is the primary wrongdoer) while building a clear, evidence-backed case against any relative whose involvement was specific and identifiable. A rushed complaint that names everyone will likely end in a quashing petition succeeding, and that outcome weakens your overall position.

This is exactly the kind of strategic decision that requires experienced 498A and criminal matrimonial counsel, not a general petition drafted in haste.

4. Your Full Legal Toolkit as the First Wife

Beyond the criminal bigamy complaint, you have several independent legal remedies that remain available — and some of them are stronger and faster than the criminal route.

A. File for Divorce Immediately

The moment your husband has contracted a second marriage without your consent and without obtaining a valid divorce, you have a clear and strong ground for contested divorce under Section 13(2)(ii) of the Hindu Marriage Act — this specific provision entitles a wife to seek divorce on the ground that her husband has, since the solemnization of their marriage, been guilty of bigamy. This is a statutory entitlement, not a discretionary relief. The family court does not need to weigh conduct or competing versions — it is a defined ground. File for this with your divorce petition from the outset.

B. Claim Maintenance Immediately

The bigamy does not suspend your maintenance rights — it strengthens them. File for interim maintenance under Section 24 of the Hindu Marriage Act or under Section 144 of the BNSS immediately alongside or soon after the divorce petition. Courts treat bigamy as a serious factor going against the husband in maintenance hearings. Your entitlement to maintenance continues during the pendency of all proceedings and cannot be denied on the basis that you have separated from the matrimonial home, particularly where the separation was caused by your husband’s conduct. Our maintenance law practice can help you file this simultaneously with the divorce petition to maximise the financial protection available to you from day one.

C. File Under the Domestic Violence Act

If your husband’s second marriage was accompanied by — or preceded by — physical cruelty, emotional abuse, financial control, or threats, you have a parallel and powerful remedy under the Protection of Women from Domestic Violence Act, 2005. A DV complaint allows you to seek a protection order, a residence order (you cannot be thrown out of the matrimonial home), and monetary relief — all on an interim basis, typically within days or weeks rather than years. The bigamy itself, and the conduct surrounding it, are directly relevant to your DV complaint. Our domestic violence practice handles these alongside matrimonial proceedings routinely.

D. Claim Your Stridhan

In the chaos that follows discovering a second marriage, women frequently forget that their jewellery, gifts received at marriage, and personal property are their absolute and exclusive property under Indian law. The husband — and his family — have no right to retain any of it. If your stridhan has not been returned, it can be claimed as part of your DV Act reliefs, or independently through a separate civil or criminal claim. Do not let it be treated as negotiating currency in a settlement — it is your property and can be reclaimed regardless of how the rest of the matrimonial dispute resolves.

E. Initiate Transfer Petition Proceedings if Necessary

If your husband has filed divorce or other proceedings against you in a court distant from where you reside — or is threatening to do so — you can file a transfer petition to consolidate all proceedings before a court convenient to you. This is particularly relevant where husbands who remarry try to use distance and the burden of travel to wear down the first wife’s ability to participate in proceedings.

5. What About the Second Wife?

I am regularly asked this as well. The second wife in a bigamous marriage is, strictly speaking, not a legal wife — the second marriage is void. However, the law does not leave her entirely without remedy.

If she was deceived about the first marriage’s existence, she can file a complaint under Section 82(2) BNS (the aggravated form of bigamy, punishable with up to ten years) and additionally under the BNS provisions for cheating. She can also claim maintenance under the Domestic Violence Act if she lived with the man as his partner — even in a void marriage, courts have consistently protected women who were deceived into these relationships. Children born of the second marriage, even if void, are legitimate under Indian law and have full inheritance rights from both parents.

What the second wife generally cannot do is claim a share of the husband’s property as a legal heir, or be treated as his spouse for inheritance purposes — that right belongs to the first wife.

6. A Word on Timing

The Supreme Court noted in Sivaraman Nair that unexplained delay in filing a complaint weakens the case — in that matter, the complainant waited six years. I tell every client the same thing: file early, or be prepared to explain why you waited.

This does not mean filing in panic or without preparation. It means that once you have made the decision to use your legal remedies, every week of delay potentially makes it easier for the other side to argue that your complaint is an afterthought. If you know about the second marriage, begin the process of documenting it — photographs, invitation cards, witness accounts, social media posts, registration details if available — and consult a matrimonial lawyer within days, not months.

7. How to Take the First Step

If you are in this situation right now, the most useful thing you can do today is speak to a specialist. Not to vent — though that helps too — but to map out, in your specific factual situation, which of the remedies above is the strongest first move, and in what order they should be filed to maximise both legal protection and practical pressure.

8. Frequently Asked Questions

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

Yes — for Hindus, Sikhs, Jains, Buddhists, Christians, and Parsis, a second marriage contracted while the first marriage is legally valid and undissolved is void and criminal under Section 82 of the Bharatiya Nyaya Sanhita (BNS), 2023. The punishment is imprisonment up to seven years. If your husband concealed your existence from the second woman, the punishment increases to up to ten years under Section 82(2).

Q2. Can I file an FIR for bigamy at the police station?

No. Bigamy under BNS Section 82 is a non-cognizable offence, meaning police cannot register an FIR and arrest directly. You must file a private complaint before a Judicial Magistrate First Class (JMFC) under Section 223 of the BNSS. The magistrate then issues summons to the accused. This is different from 498A (which is cognizable) and matters strategically — getting your complaint drafted correctly before the magistrate is the critical first step.

Q3. Can I file a case against my in-laws for my husband’s second marriage?

Only if you have specific evidence of their active role in arranging, facilitating, or encouraging 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 being present at the event — is not enough to sustain a criminal prosecution against relatives. Vague or omnibus allegations without specific attributed conduct will likely be quashed.

Q4. My husband is living with another woman but hasn’t formally married her. Is that bigamy?

No. Bigamy specifically requires that a valid second marriage was solemnized with proper religious rites. A live-in relationship, however open or long-standing, does not constitute a second marriage for criminal law purposes. The Karnataka High Court confirmed this in March 2026 and quashed a bigamy complaint based solely on allegations of cohabitation. Your remedies in this situation may include divorce on cruelty grounds and maintenance — but not a bigamy complaint.

Q5. Does my maintenance stop because my husband has a second family now?

No. Your maintenance entitlement as the first wife is unaffected by — and in practice often strengthened by — your husband’s bigamy. Courts factor his conduct and his financial obligations into the maintenance calculation, but his remarriage does not extinguish what he owes you. File for interim maintenance immediately alongside your divorce petition.

Q6. Can I get a divorce specifically because my husband remarried?

Yes — Section 13(2)(ii) of the Hindu Marriage Act specifically provides a wife with the right to seek divorce on the ground that the husband has been guilty of bigamy since the marriage. This is a defined statutory ground, not subject to the court’s general discretion on fault. You are entitled to file for divorce on this basis.

Q7. What rights does the second wife have?

The second marriage is void under law and she is not a legal wife. However, if she was deceived about the existence of the first marriage, she has remedies under Section 82(2) BNS and the BNS cheating provisions. She can claim maintenance under the Domestic Violence Act if she cohabited with the husband as a domestic partner. Children of the second marriage are fully legitimate and have inheritance rights. She generally cannot claim the husband’s property as a legal heir — that right belongs to the first wife.

Q8. How do I prove that a second marriage actually took place?

Proof of a valid second marriage requires evidence that the proper religious ceremonies were performed — for Hindus, this typically means establishing that the saptapadi took place. Admissible evidence includes photographs of the ceremony, video footage, invitation cards, witness testimony from attendees, records of the marriage registration (if registered), social media posts from the event, and any correspondence acknowledging the second marriage. A bare admission by the husband alone, the Supreme Court has held, is not sufficient to prove bigamy.

Q9. My husband divorced me after remarrying. Is the divorce valid?

A divorce obtained after remarrying does not retroactively make the second marriage legal. The criminal act of bigamy was complete the moment the second marriage was solemnized while the first marriage was undissolved. However, a valid divorce decree does affect your ongoing maintenance rights and marital status going forward. You should seek specific legal advice on the timeline and sequence of events in your case.

Q10. What should I do first — file for bigamy or file for divorce?

In most cases, I advise clients to file for mutual consent divorce or contested divorce simultaneously with interim maintenance as the primary and most urgent remedies, while the bigamy complaint is prepared carefully and filed when the evidence is properly documented. Rushing a bigamy complaint with generic drafting often leads to a quashing petition succeeding — which wastes time and weakens your position. The criminal complaint is a tool of pressure and justice, but the divorce and maintenance route is what secures your financial and legal position most reliably and most quickly.
