Yes, a live-in relationship is legal in India. The Supreme Court has held that two consenting adults can live together without marrying, and the law can treat a long-term live-in as a “relationship in the nature of marriage” that carries real rights. Those rights are not automatic. They depend on whether your relationship meets a set of conditions the courts have laid down, and one state, Uttarakhand, now requires such couples to register.
If you are short on time, first check your relationship against the four conditions below, then read the protection and maintenance sections.
The Supreme Court in D. Velusamy v. D. Patchaiammal (2010) set four conditions for a live-in to count as a “relationship in the nature of marriage”. This test matters because most of your rights flow from meeting it. Check yours against all four:
The same judgment made one point clear. A casual relationship, a weekend arrangement, or a one-night stay is not a “relationship in the nature of marriage”. The couple must have actually cohabited and shown the world they live as spouses.
Once a live-in meets the four conditions, the law steps in on four fronts.
The Protection of Women from Domestic Violence Act, 2005 protects a woman in a live-in, not just a wife. Section 2(f) defines a “domestic relationship” as:
“a relationship between two persons who live or have, at any point of time, lived together in a shared household, when they are related by consanguinity, marriage, or through a relationship in the nature of marriage, adoption or are family members living together as a joint family”.
Because “a relationship in the nature of marriage” is written into the definition, a qualifying female partner can approach a magistrate for the Act's reliefs. These can include a protection order, the right to stay in the shared household, and monetary support. To act on this, read our guide on how to file a domestic violence complaint and what a residence, protection and monetary relief order covers.
There are two different routes here, and it matters which one you use.
The reliable route is the Domestic Violence Act itself. Section 20 of that Act is headed “Monetary reliefs”, and it lets a magistrate order the respondent to pay maintenance for the aggrieved person and her children, along with loss of earnings and medical expenses. Because a qualifying live-in partner falls inside the Act's “domestic relationship”, this route is open to her.
The harder route is the general maintenance law. Section 144 of the Bharatiya Nagarik Suraksha Sanhita, 2023 is titled “Order for maintenance of wives, children and parents”, and it replaced Section 125 of the old Code of Criminal Procedure from 1 July 2024. The CrPC no longer applies. But that section speaks of a “wife”, and in Velusamy the Supreme Court took a narrow view of who counts as a wife. In Chanmuniya v. Virendra Kumar Singh Kushwaha, decided on 7 October 2010, a Bench favoured a broader reading and referred the question to a larger Bench. So the position under this route is unsettled, and outcomes differ between courts.
The practical takeaway: a woman in a live-in should normally seek monetary relief under the Domestic Violence Act rather than assume the BNSS “wife” route is open. For the general maintenance provision, see maintenance under BNSS Section 144.
Children born from a live-in relationship are not treated as illegitimate outcasts. Indian courts have long recognised that a child of a stable, long-term live-in is legitimate for the purposes that matter to the child. Paternity can be established, and a father cannot walk away from a child simply because the parents never married. If paternity is disputed, our page on DNA tests, paternity and child maintenance explains how courts approach it.
A child of a live-in relationship can inherit the self-acquired property of a parent. The child's right to a parent's own property does not depend on the parents being married.
There is a limit worth knowing. In Bharatha Matha v. R. Vijaya Renganathan, decided on 17 May 2010, the Supreme Court held that a child born of a live-in relationship may claim a share in the parents' self-acquired property but cannot claim inheritance in Hindu ancestral coparcenary property. So the child's claim reaches the parent's own assets, not the wider joint family estate.
Note a firm limit here. The partners themselves do not automatically inherit from each other. A live-in partner is not treated as a spouse for succession, so if one partner dies without a will, the other has no automatic claim on the estate. If you want your partner to inherit, you need a valid will. The RTI Playbook can help you understand and demand the public records that prove property and relationship facts when a dispute starts.
Uttarakhand is different from the rest of India. Under the state's Uniform Civil Code, live-in couples in Uttarakhand must register their relationship. A partner submits a statement of the live-in relationship to a Registrar. The state code also provides penalties for couples who do not comply.
Because this is a new and changing law, do not rely on any figure you read second-hand. The rules have already been amended several times. Check the current requirements directly on the official portal at ucc.uk.gov.in before you act.
This registration duty is specific to Uttarakhand. It is not the rule in the rest of India. Outside Uttarakhand, there is no law that makes you register a live-in relationship, and living together without marrying is not itself an offence anywhere in the country.
A live-in is not the same as a marriage. Clearing up two common myths saves a lot of heartache:
Knowing these limits helps you plan. If financial security matters to you, put it in writing while the relationship is good.
Yes. Two consenting adults can live together without marrying anywhere in India. The Supreme Court has repeatedly upheld this as part of the right to life and personal liberty. The only added step is in Uttarakhand, where the state's Uniform Civil Code requires such couples to register their relationship.
A woman can, if her relationship meets the four conditions the Supreme Court set in D. Velusamy v. D. Patchaiammal. The dependable route is Section 20 of the Domestic Violence Act, headed “Monetary reliefs”, under which a magistrate can order maintenance. Whether she also counts as a “wife” under Section 144 of the BNSS, 2023 is unsettled, and that question was referred to a larger Bench in Chanmuniya. A casual or short relationship usually will not qualify at all.
Yes, for the purposes that protect the child. A child born from a stable live-in relationship is entitled to support from both parents and can claim a share in a parent's self-acquired property. In Bharatha Matha v. R. Vijaya Renganathan the Supreme Court drew the line at Hindu ancestral coparcenary property, which such a child cannot claim. The child's rights do not depend on the parents having married each other.
Not automatically. A live-in partner is not a legal spouse for succession, so the survivor has no automatic claim on the deceased partner's estate. The only safe way to pass property to a partner is a valid will, a joint holding, or a nomination.
Only in Uttarakhand. There, the state code requires registration and provides penalties for non-compliance, so check the current rules on ucc.uk.gov.in. In the rest of India, no law requires you to register a live-in relationship.
A live-in relationship is legal in India, and a long-term, committed one carries real protection against domestic violence, a possible maintenance claim, and firm rights for any children. What it does not give you is an automatic inheritance between partners or the status of a married couple. If you live in Uttarakhand, register your relationship and check the current rules on the official portal. Everywhere else, protect yourself with clear documents while things are calm.
