Is a live-in relationship legal in India, and what rights does it give?

Is living together without marriage legal?

Yes. No Indian law makes cohabitation between consenting adults an offence. The Supreme Court in S. Khushboo v. Kanniammal (2010) said living together is part of the right to life and liberty, and later decisions have repeatedly asked police to protect adult couples facing threats from families.

Legality, however, is not the same as rights. A marriage automatically brings a framework of maintenance, inheritance and divorce. A live-in relationship does not. Rights flow only in specific situations, mainly under the Protection of Women from Domestic Violence Act, 2005 (PWDVA), which covers a "relationship in the nature of marriage", and through presumptions courts apply to long cohabitation.

What is a 'relationship in the nature of marriage'?

Two judgments set the tests.

In D. Velusamy v. D. Patchaiammal (2010), the Supreme Court said the couple must hold themselves out to society as akin to spouses, be of legal age to marry, be otherwise qualified to marry (including being unmarried), and have voluntarily cohabited for a significant period. It added that a weekend together or a one-night stand would not qualify.

In Indra Sarma v. V.K.V. Sarma (2013), the Court gave broader guidelines to weigh: duration of the relationship, a shared household, pooling of resources and finances, domestic arrangements, a sexual relationship, children, socialising in public as a couple, and the intention and conduct of the parties. No single factor decides; the overall picture does.

What rights do live-in partners have?

• Protection from domestic violence: a woman in a qualifying relationship can seek protection, residence, monetary relief and compensation under the PWDVA. Evidence needed is discussed in proving a domestic violence case.
• Maintenance: through PWDVA monetary relief. Whether BNSS s.144 (earlier CrPC 125) applies directly to live-in partners has been debated; in Chanmuniya v. Virendra Kumar Singh Kushwaha (2010) the Court favoured a broad reading and referred the question to a larger bench. Several High Courts allow claims where a long cohabitation raises a presumption of marriage.
• Presumption of marriage: long, continuous cohabitation can lead courts to presume a valid marriage unless rebutted (Kattukandi Edathil Krishnan v. Valsan, 2022).
• Protection of life and liberty: couples facing threats can approach the police and the High Court; the principles of protection for couples marrying without family consent are often applied to live-in couples as well.

There is no automatic right to inherit the partner's property. That needs a will, joint ownership or a presumed marriage.

What are the rights of children born in a live-in relationship?

Children of a long-term live-in relationship are generally treated as legitimate (Tulsa v. Durghatiya, 2008). They are entitled to maintenance from the father and can inherit their parents' property. Hindu law questions on shares in ancestral coparcenary property were addressed by a larger bench in Revanasiddappa v. Mallikarjun (2023), which allowed such children a share in the parent's portion. Paternity disputes may involve a DNA test, ordered only in limited circumstances; see DNA paternity tests in India and rights of a child born outside marriage.

Can a married person be in a live-in relationship?

It is not a crime. Adultery was decriminalised in Joseph Shine v. Union of India (2018) and there is no offence of adultery in the BNS. Living with someone else is not bigamy either, because bigamy under BNS s.82 needs a second marriage ceremony; see bigamy and second marriage law.

But there are real consequences:

• The spouse can seek divorce on grounds of adultery or cruelty; see legal action against a cheating spouse.
• The live-in partner of a married man is usually not in a "relationship in the nature of marriage", since he is not qualified to marry. In Indra Sarma the woman, who knew he was married, was denied PWDVA relief as a partner, though the Court urged Parliament to consider protection for such women.
• Several High Courts have refused police protection petitions by couples where one partner is still married, while others have granted protection of life without endorsing the relationship. Outcomes vary by court.

Can a live-in relationship be registered, and is an agreement valid?

Most of India has no registration system for live-in couples. The exception is Uttarakhand, whose Uniform Civil Code (in force from January 2025) requires couples in live-in relationships in the state to register with the Registrar, with penalties for not doing so. Check the current rules if you live there.

Elsewhere, couples sometimes sign a cohabitation agreement covering rent, shared assets and expenses. Such an agreement can help prove finances and intention, but it cannot take away statutory rights such as protection from violence, and terms against public policy are unenforceable. Notarisation does not make it a marriage.

What legal problems arise when a live-in relationship ends?

Because there is no divorce, disputes after a break-up are handled piece by piece. The common ones are:

• Money and property: who owns the flat, car or savings bought together. Title documents and bank trails decide this, not the relationship.
• Residence: a woman in a qualifying relationship may seek a residence order under the PWDVA to stay in the shared household for a period.
• Children: custody and maintenance are decided on the child's welfare, as in any other case.
• Criminal complaints: allegations of cheating, assault, stalking or misuse of intimate images. Sharing a partner's private images is an offence under IT Act s.66E and s.67A; help for victims is in deepfake and morphed photo abuse.

Keep copies of rent agreements, payment records and messages in case a dispute arises, and avoid informal oral promises about property. Where a partner disappears with money or shared assets, locating them lawfully and tracing what was taken becomes a separate task for your lawyer and, if needed, an investigator.

How do you prove a live-in relationship in court?

1. Collect proof of a shared address: rent agreement, utility bills, bank or Aadhaar address records in both names.
2. Show pooled finances: joint accounts, shared EMIs, transfers for household expenses.
3. Gather public acknowledgement: photos at family events, invitations, social media posts, statements by neighbours, landlord or society staff.
4. Document duration with dated material across years.
5. Keep children's records naming both parents, such as birth certificates and school forms.

When a partner disputes the relationship, or a person claims a relationship that did not exist, lawful fact-finding can confirm addresses and public conduct. A verified investigator through our detective directory can help, without accessing private accounts or records.

Bottom line

A live-in relationship between adults is legal, but its protection depends on proof that it resembled a marriage. Keep records of a shared life, understand that a married partner changes the picture, and seek legal advice early if you need protection, maintenance or clarity for your children.
