Bigamy law in India makes it a criminal offense to marry a second time while your first marriage is still legally valid, with penalties of up to seven years in prison under Section 82 of the Bharatiya Nyaya Sanhita (BNS), which replaced the Indian Penal Code on July 1, 2024. Which rules apply to you depends on the religion under which your marriage was performed, because India runs parallel marriage statutes for different communities. That means the same act can be criminal for one person and lawful for another.
Who Is Allowed More Than One Spouse
For most Indians, the answer is nobody. The Hindu Marriage Act of 1955 imposes strict monogamy on Hindus, Buddhists, Jains, and Sikhs. Section 17 of the Act declares any marriage performed while a previous spouse is alive void from the start and triggers criminal penalties for bigamy.1Indian Kanoon. Hindu Marriage Act, 1955 – Section 17
The same restriction reaches anyone married under the Special Marriage Act of 1954, regardless of religion. Section 4 of that Act requires that neither party have a living spouse at the time of the marriage.2India Code. Special Marriage Act, 1954 The Parsi Marriage and Divorce Act of 1936 contains a similar prohibition,3India Code. Parsi Marriage and Divorce Act, 1936 and Christians married under the Indian Christian Marriage Act of 1872 are likewise bound to monogamy.
The Muslim Personal Law Exception
Muslim personal law, applied through the Muslim Personal Law (Shariat) Application Act of 1937, permits a Muslim man to have up to four wives simultaneously. This allowance does not extend to Muslim women, who face prosecution for bigamy if they marry while a husband is alive.
This religious exception cannot be used as a workaround. In Sarla Mudgal v. Union of India (1995), the Supreme Court dealt with cases where Hindu men converted to Islam specifically so they could take a second wife without divorcing the first. The Court held that a Hindu marriage can only be dissolved under Hindu law, and converting to Islam does not dissolve it. The second marriage remains void, and the husband can be prosecuted for bigamy.4Indian Kanoon. Sarla Mudgal, President, Kalyani and Ors vs Union of India and Ors on 10 May, 1995
The Punishment: BNS Section 82
Bigamy is now prosecuted under Section 82 of the Bharatiya Nyaya Sanhita rather than the old IPC. The substance hasn’t changed; the new law simply consolidates what used to be IPC 494 and 495 into a single provision with two subsections.
Under BNS Section 82(1), anyone who marries while a spouse is still living faces imprisonment of up to seven years and a fine.5Devgan.in. BNS Section 82 – Marrying Again During Lifetime of Husband or Wife The offense is non-cognizable and bailable. That means police cannot arrest you without a warrant, and you have the right to bail.
The penalty climbs sharply if you hide the first marriage from your new spouse. BNS Section 82(2) treats concealment as an aggravated form of bigamy, punishable by up to ten years of imprisonment and a mandatory fine.5Devgan.in. BNS Section 82 – Marrying Again During Lifetime of Husband or Wife Most of the real prison time in bigamy cases falls under this subsection. Openly taking a second spouse is one thing; deceiving someone into a bigamous marriage is treated more harshly.
There is no limitation period for filing a bigamy complaint. Years or even decades after the second marriage, a complaint can still be lodged. Delay may weaken the evidence, but it does not extinguish the right to prosecute.
When Bigamy Is Not Bigamy
A bigamy charge does not stick on its own weight. Two things have to be proved, and either one can bring the case down.
The prosecution must first show the first marriage was legally valid and still subsisting when the second ceremony took place. A subsisting marriage is one that has not been ended by a final divorce decree or the death of a spouse. Marriage certificates, testimony from witnesses to the ceremony, and other documentary proof are what courts look for.6Indian Kanoon. Bindu vs Raj Kumar
The prosecution must also prove the second marriage was actually solemnized with proper rites or legal procedures. This is where many cases collapse. In Bhaurao Shankar Lokhande v. State of Maharashtra, the Supreme Court held that merely living together or going through an informal ceremony with the intention of being considered married is not enough. For a Hindu marriage, essential ceremonies such as the invocation before sacred fire and the saptapadi (seven steps) must be performed, unless a specific community custom has replaced them.7Indian Kanoon. Bhaurao Shankar Lokhande and Anr vs State of Maharashtra and Anr Without proof of these rites, the charge fails even where the first marriage is clearly valid.
The Seven-Year Absence Exception
BNS Section 82 itself provides an exception where a spouse has been missing for a long time. You can remarry without facing bigamy charges if all three of these conditions are met:
- Your spouse has been continuously absent for at least seven years.
- You have not heard of your spouse being alive during that entire period.
- Before the new marriage, you disclose the situation to your intended partner as far as you know it.
The third condition catches people out. Even if your spouse has been gone for a decade, remarrying without telling the new partner about the situation removes the protection.8Indian Kanoon. Indian Penal Code 1860 – Section 494
A separate defense applies where a court of competent jurisdiction has already declared the first marriage void. A marriage judicially declared void is treated as though it never existed, and a later marriage cannot be bigamous.
Filing a Bigamy Complaint
Bigamy runs on a different track from most criminal cases. Because the offense is non-cognizable, police cannot register an FIR or investigate on their own. A magistrate also cannot direct the police to register and investigate. The case moves forward only as a private complaint filed directly with a magistrate’s court.9Indian Kanoon. Iftekhar Ahmad and Another vs State of U.P. and Another
Who Can File
Under Section 198 of the Code of Criminal Procedure, now carried forward in the Bharatiya Nagarik Suraksha Sanhita, only a person “aggrieved by the offense” can file. In almost every case, that means the first spouse. Where the aggrieved person is a wife, the complaint can also be filed on her behalf by a parent, sibling, son, daughter, or an uncle or aunt on either side. More distant relatives by blood, marriage, or adoption may file only with the court’s permission.9Indian Kanoon. Iftekhar Ahmad and Another vs State of U.P. and Another
Evidence That Actually Works
A workable complaint needs solid proof of both the first marriage’s validity and the second marriage’s solemnization. Courts have accepted the following:6Indian Kanoon. Bindu vs Raj Kumar
- A marriage certificate for the first marriage.
- Testimony from the priest who performed either ceremony, from guests, or from the photographer.
- Photographs and video of the second marriage ceremony, especially images showing religious rites being performed.
- Invitations, social media posts, or any other written acknowledgment of the second marriage.
Once accepted, the matter proceeds as a complaint case. The complainant carries the initial burden of presenting evidence before the magistrate decides whether to issue process against the accused.
The Second Spouse and the Children
A bigamous marriage among Hindus is void from its inception. Section 17 of the Hindu Marriage Act says so directly, and Section 11 reinforces it by declaring void any marriage where either party already had a living spouse.10Indian Kanoon. Hindu Marriage Act, 1955 – Section 11 The second spouse has no legal standing as a husband or wife for purposes like inheritance or joint property ownership.
Children Are Treated Differently From the Marriage
Children fare far better than the union that produced them. Section 16 of the Hindu Marriage Act declares children of void marriages legitimate, whether born before or after a decree of nullity, and the legitimacy is automatic.11Devgan.in. Hindu Marriage Act Section 16 – Legitimacy of Children of Void and Voidable Marriages
The Supreme Court settled the scope of inheritance rights in Revanasiddappa v. Mallikarjun (2023). Children from void marriages can inherit their parent’s property, including the share their parent would have received in a notional partition of ancestral coparcenary property. What they cannot do is claim partition of the larger coparcenary in their own right. In practice, they inherit through their parent’s share, not directly from the joint family.12CSJA. Revanasiddappa vs Mallikarjun Judgement
Maintenance for the Second Spouse
A void marriage does not always leave the second spouse without financial recourse. Section 144 of the Bharatiya Nagarik Suraksha Sanhita, which replaced Section 125 of the Code of Criminal Procedure, provides for maintenance of wives, children, and parents.13India Code. Bharatiya Nagarik Suraksha Sanhita, 2023 – Section 144 The Supreme Court has held that a woman can claim maintenance from her second husband even where the earlier marriage was still legally subsisting, reading these welfare provisions expansively rather than strictly. Courts generally lean toward preventing destitution, particularly where the second spouse was deceived about the first marriage.
Extra Consequences for Government Employees
Government service adds a layer on top of the criminal law. Rule 21 of the Central Civil Services (Conduct) Rules, 1964 prohibits any government servant from marrying a person who already has a living spouse, or from taking a second spouse while already married.14Referencer. Central Civil Services (Conduct) Rules 1964 – Rule 21 Even without a criminal prosecution, a bigamous marriage can trigger disciplinary action up to termination. A void marriage still counts as a violation for employment purposes unless the government has specifically granted an exemption.
The Central Government can allow a second marriage in narrow cases, but the bar is high. It weighs whether the marriage is permissible under the employee’s personal law, whether the stated grounds are genuine, whether the first spouse has genuinely consented, and whether adequate maintenance arrangements exist for the first spouse. When the application rests on the first spouse’s illness, the government consults medical authorities before deciding.15Referencer. Central Civil Services (Conduct) Rules, 1964 – Rule 21 GOI Decisions Exemptions are rare in practice and are almost exclusively granted where Muslim personal law applies to the employee.
