Grounds on which marriage is not valid in India- A marriage is not solely an emotional relationship; it is also a legal one. However, not all marriages are recognized as legal in India. A marriage may be void or voidable according to the law if it fails to satisfy specific conditions with respect to age, consent, mental ability, existing marriage, or relation between family members. Even now, child marriage is a problem in India; NFHS-5 statistics indicate that almost 23% of women were married off below the age of consent, and there have been complications associated with marriage of this nature.
The legality of the marriage depends on various personal laws like the Hindu Marriage Act, 1955, the Muslim Personal Law, the Special Marriage Act, 1954, etc. All these personal laws clearly lay down situations when the marriage will be considered lawful and at the same time provide provisions where such a marriage may be invalidated. Invalid marriages could have certain legal implications on rights such as maintenance, succession, property, etc., and even the issue’s legal status. This blog will simplify and clearly explain the grounds on which a marriage is not invalid in India.

What Makes a Marriage Invalid Under Indian Law?
Not every marriage that happens is legally valid. Some marriages look real. There is a ceremony. There are guests. There are rituals. But according to the law, that marriage never happened. Indian law divides invalid marriages into two clear categories.
Void Marriage vs. Voidable Marriage: What Is the Difference?
This is the most important thing to understand before anything else. A void marriage has no legal existence from day one. It is as if the marriage never happened. No rights are created. No duties arise. You do not even need a court order to call it invalid, though getting one is always advisable for legal clarity.
A voidable marriage, on the other hand, is technically valid. It exists in law. But one of the parties can go to court and get it annulled. Until the court cancels it, it is considered a legal marriage. An invalid marriage is not the same as a divorce.
Here is a simple table to understand the difference:
| Void Marriage | Voidable Marriage | |
| Legal Status | Invalid from day one | Valid until annulled by the court |
| Who can challenge it | Anyone | Only the husband or wife |
| A court order is needed | Not mandatory | Yes, must approach the court. |
| Example | Bigamy, sapinda marriage | Fraud, impotence, unsound mind |
Many people confuse annulment with divorce. These are two completely different things.
Divorce ends a valid marriage. An annulment says the marriage was never valid to begin with. This difference matters, especially for property rights, maintenance, and the status of children.
Void Marriages in India – Marriages That Never Legally Existed
There is no void marriage in law. It is void ab initio. It confers no rights and imposes no obligation. In India, marriage may be void if:
Bigamy: Having a spouse who is still alive.
- Where either the husband or the wife has been previously married to some other person now alive, such subsequent marriage is void.
- This is covered under Section 11 of the Hindu Marriage Act and Section 82 of BNS (earlier Section 494 IPC).
- Bigamy is not just a civil wrong; it is a criminal offense. The guilty person can face up to 7 years of imprisonment.
- The first marriage remains valid. The second marriage has no legal standing at all.
Marriage Within Prohibited Degrees of Relationship
- There are certain relatives you just shouldn’t marry. Within Hinduism, the Hindu Marriage Act prohibits marriages between brother-sister, uncle-niece, or aunt-nephew relationships.
- Such a marriage is considered void by law.
- However, there is an exception: In certain communities (mostly in South India), a system has existed for a long time, permitting marriages between cousins. Such marriages are valid.
- The custom must be well-known and consistently followed in that community. Only then will the court accept it.
Sapinda Marriages – Too Close in Bloodline
- A sapinda relationship simply refers to how closely related two people are on a generation level. Under Hindu law, the mother has to be 3 generations away from the daughter in the male line, while the father has to be 5 generations away from the son in the male line.
- If both persons happen to be within this range, their marriage will be void.
- A large number of people are unaware of this rule, but this rule has been rigorously applied in some judgments.
Child Marriage – Below the Legal Age
- The legal age of marriage is 18 years for females and 21 years for males.
- The Prohibition of Child Marriage Act, 2006, regulates child marriages.
- Critical factor: Child marriage is voidable, not void, which means it is not invalid from the start. It can be challenged in a court of law by only the child (underage) and only if he/she is under 20 years. Legally, it is a legal marriage until someone challenges it.
How to File a Case for Declaration of Invalid Marriage in India
Filing a case for an invalid marriage is not as complicated as it sounds. But you need to follow the right process. Here is a simple step-by-step guide to help you understand how it works.
- Consult a Family Lawyer First- The first thing you should do is to consult with a qualified family lawyer. He will tell you what exactly you should do.
- Gather All Important Documents- Another thing you should keep in mind is to keep your essential documents ready. These include a marriage certificate, an Aadhaar card, and any proof supporting your ground for invalidity.
- File a Petition in Family Court – Subsequently, you have to file a petition in the family court of the district in which the marriage was performed or in which you are presently residing.
- Notice to the Other Party from the court – After filing the petition, the court will send a notice to your spouse to enable him to be present, present his case, and reply.
- Evidence submitted by both parties – You and your spouse will need to appear in court to give evidence in the form of your statement and documents. Witnesses can be examined as per the requirement.
- Court gives its order – If the court finds it satisfactory, then it issues a decree of nullity in this respect.
Recent Supreme Court and High Court Judgements on Invalid Marriages
The following are the judgments that you should know. The recent ones are far more protective, especially for women and children.
1. Lily Thomas vs Union of India – Supreme Court (2000)
A Hindu man was already married. His wife was alive. But he wanted to remarry. So he converted to Islam, thinking it would allow him to have a second wife legally.
The Supreme Court did not accept this.
The court clearly said that converting to another religion just to escape bigamy laws is not valid. The second marriage was void. The man was still liable for bigamy.
2. Yamuna Bai vs Anant Rao Shivram – Supreme Court (1988)
A woman believed she was legally married. Later, it came out that her husband already had a wife. Her marriage was void from day one.
She approached the court for maintenance. The Supreme Court denied it, saying she was not a legal wife since the marriage never existed.
The judgment left an innocent woman without protection. But it pushed lawmakers to bring the Domestic Violence Act, 2005, which now protects women even in void marriages.
Conclusion
Marriage is more than a cause for celebration. Marriage is a legal contract and every contract has its terms and conditions, which need to be fulfilled for it to be valid legally. If you are a victim of any such condition, do not wait and contact an experienced family lawyer like Advocate Amit Gupta immediately.
