Nevada Cohabitation Law
Living together in Nevada does not automatically give an unmarried couple the same legal rights as spouses. Nevada does not create a new common-law marriage simply because two people live together for years, share bills, buy property, or call each other husband and wife. But unmarried partners can still have significant legal rights depending on property title, written or implied agreements, financial conduct, parentage, registered domestic partnership status, and other facts.
Some of the hardest relationship breakups are not divorces at all.
Two people may live together for 5, 10, 15, or 20 years. They may buy a home together, share accounts, raise children, build a business, pay one another's expenses, or arrange their finances as though they were married.
Then the relationship ends.
One person believes, “We built this life together, so I am entitled to half.” The other says, “The house and accounts are in my name, so you are entitled to nothing.”
In Nevada, neither assumption should be accepted without looking at the evidence.
The legal question is usually not simply how long the relationship lasted. It is what legal rights the couple actually created during the relationship and what can now be proven.
The key rule: ordinary cohabitation does not automatically create Nevada community-property rights. But Nevada courts recognize that unmarried people may create enforceable property rights through contracts, implied agreements, co-ownership, and other recognized legal theories.
Marriage vs. Cohabitation in Nevada: The Differences That Matter
Nevada law gives married spouses substantial statutory rights and obligations. Simply sharing a home does not automatically create those same rights.
| Issue | Married Couple | Ordinary Unmarried Cohabitation |
|---|---|---|
| Community property | Property acquired during marriage is generally subject to Nevada community-property law unless an exception applies. | No automatic community-property status merely because the couple lives together. |
| Breakup process | Property, support and other marital issues can be resolved in a divorce proceeding. | Different claims may need to be addressed through property, contract, parentage, custody or other proceedings. |
| Alimony | A Nevada divorce court may award spousal support when legally appropriate. | There is no automatic right to divorce alimony merely because the parties lived together. |
| Common-law marriage | A valid marriage creates marital rights. | Nevada does not create a new common-law marriage merely from cohabitation. |
| Inheritance | A surviving spouse may receive statutory rights under Nevada succession law. | An ordinary unmarried cohabitant does not automatically receive the inheritance rights of a spouse. |
| Children | Custody is decided under Nevada parentage and custody law. | Unmarried legal parents may also pursue custody, but parentage may first need to be established or resolved. |
| Registered domestic partnership | Spouses receive marital rights under Nevada law. | A formally registered Nevada domestic partnership is different from ordinary cohabitation and generally carries spouse-equivalent state-law rights and duties. |
Nevada does not recognize a new common-law marriage simply because a couple has lived together for a certain period of time. For the full discussion of that separate issue, see our guide to common-law marriage in Nevada.
If you are legally married and need the rules that apply to marital property, see our separate explanation of Nevada community property law.
“We've Lived Together for Years. Am I Entitled to Half?”
Not automatically.
There is no Nevada rule that awards an unmarried partner half of everything merely because a relationship lasted 5 years, 10 years, or 20 years.
The length of the relationship can still be important evidence because a long financial history may show how the parties treated their property. But duration alone does not create a marriage or a 50/50 property division.
Nevada courts have recognized that unmarried partners can create enforceable agreements concerning property. Those agreements may sometimes be written expressly or inferred from the parties' conduct.
That changes the question from:
“How long were you together?”
to:
“What did you agree to do with the property, and what evidence shows that agreement?”
Breaking Up Without Being Married?
If a house, money, business, children or years of shared financial contributions are involved, do not assume the law treats the breakup like a divorce. Rosenblum Allen can help identify what rights actually exist under Nevada law.
Call (702) 433-2889Property Rights When an Unmarried Couple Separates
People often begin with title: whose name appears on the deed, account, vehicle or business paperwork.
Title can be extremely important. But Nevada cohabitation cases show that it may not always answer every question.
Depending on the evidence, a property dispute may involve an express contract, an implied agreement demonstrated through conduct, co-ownership rights, partnership or joint-venture principles, partition of real estate, or equitable remedies.
That does not convert unmarried property into community property.
It means a court may need to determine what ownership rights were actually created between the parties.
Title Is a Starting Point, Not Always the Entire Analysis
In Hay v. Hay, the Nevada Supreme Court addressed an unmarried couple who had lived together for approximately 23 years after previously divorcing. The plaintiff alleged that the parties pooled their money and acquired property as though they were married or operating as general partners.
The court recognized that unmarried people have the right to contract with one another concerning property and that an agreement can be express or implied from conduct.
That is why a deed matters, but the surrounding evidence may matter too.
Who Gets the House If You Are Not Married?
The house is often the point where an unmarried breakup becomes expensive.
There are several very different scenarios, and they should not be treated as though they produce the same result.
If Both Partners Are on the Deed
If both people hold title as joint tenants or tenants in common, Nevada's partition laws may provide a mechanism for resolving ownership when the parties can no longer agree about the property.
A partition case is not the same thing as dividing a community-property residence in divorce. The court is addressing co-ownership rights, the parties' respective interests, and whether the property can be divided or should be sold.
If Only One Partner Is on the Deed
This is where evidence becomes especially important.
We would want to know how the down payment was made, whether the other partner contributed substantial money toward acquisition or equity, where mortgage payments came from, whether there were major renovations, and what the parties said about ownership.
A text saying “our house” does not automatically transfer title. Likewise, the absence of someone's name from the deed does not necessarily answer every possible contract or equitable claim.
If One Partner Owned the Home Before the Relationship
Moving into someone's preexisting house does not automatically create a half-interest in that property.
Paying groceries, utilities or routine household expenses also does not automatically transform the owner's existing equity into jointly owned property.
The issue becomes more complicated if the parties later changed title, refinanced together, made a specific ownership agreement, or invested substantial money under an understanding that the contributing partner was acquiring an ownership interest.
What Happens to Bank Accounts, Vehicles, Personal Property and Debt?
The same principle applies to other assets: there is no automatic divorce process that labels everything “community” or “separate.”
| Issue | What We Would Examine |
|---|---|
| Joint bank account | Who deposited the funds, why the account was created, how the money was used, and whether the parties treated the funds as jointly owned. |
| Bank account in one name | The source of the funds, any agreement concerning ownership, and whether the other partner can prove a legal interest despite title. |
| Vehicle | Title, financing, payment history, insurance, contributions and any agreement about who owned the vehicle. |
| Furniture and valuables | Receipts, account records, gift history and communications showing who purchased or owned the property. |
| Joint debt | The loan or credit agreement with the creditor and any separate agreement between the partners about who was supposed to pay. |
| Business or investment | Ownership records, capital contributions, contracts, tax treatment, compensation and whether the parties operated as business partners. |
One important practical point: an agreement between former partners about who will pay a debt does not necessarily change the rights of the bank, lender or creditor. The underlying contract still matters.
Can an Unmarried Partner Get Alimony in Nevada?
Ordinary cohabitation does not create an automatic right to Nevada divorce alimony.
Under NRS 125.150, alimony is awarded in connection with divorce. A person does not become entitled to that statutory remedy simply because the relationship was long, one partner earned significantly more money, or the lower-earning partner became financially dependent.
That does not mean financial promises are always irrelevant. A separate contractual claim may exist if the parties actually entered an enforceable agreement concerning support. But that is legally different from saying, “We lived together for 15 years, therefore I get alimony.”
Important distinction: financial dependence alone does not turn an unmarried relationship into a marriage. The existence of a legally enforceable agreement can raise a different issue.
For the rules that govern spousal support after an actual Nevada marriage, see How Alimony Works in Nevada.
Does Cohabitation End Alimony in Nevada?
No. Cohabitation by itself does not automatically terminate alimony in Nevada.
The Nevada Supreme Court addressed this issue directly in Gilman v. Gilman. The court rejected an automatic rule based simply on living with a new romantic partner.
Instead, cohabitation may support modification of alimony when the new living arrangement actually decreases the recipient spouse's financial need.
That means the financial facts matter. If a new partner substantially pays the recipient's housing, utilities or other living expenses, the court may examine whether the recipient's actual need for support has decreased. Merely sharing a residence or being in a marriage-like relationship, standing alone, does not automatically end support.
The divorce decree or settlement agreement can also change the analysis. The parties may include enforceable language addressing what happens if the recipient later cohabits with another person.
Nevada rule: cohabitation alone is not enough. The question is whether the relationship has actually reduced the recipient's financial need, unless the decree or agreement contains its own controlling cohabitation provision.
For the broader rules governing Nevada spousal support, see How Alimony Works in Nevada.
Not Sure Whether This Is a Property Case, Support Case or Family Court Case?
That is often the most important question to answer first. Rosenblum Allen can evaluate how the relationship was structured and identify which Nevada legal remedies actually apply.
Speak With Rosenblum AllenCohabitation Agreements: Decide the Rules Before There Is a Dispute
A written cohabitation agreement can reduce uncertainty by documenting what each partner owns and what the parties intend to happen if the relationship ends.
Depending on the circumstances, an agreement can address existing property, future acquisitions, responsibility for household expenses, ownership of a home, debt allocation, business interests and agreed financial obligations.
The goal is not to make the couple “married.” The goal is to create contractual clarity where Nevada marital statutes would otherwise not automatically apply.
What If There Is No Written Agreement?
A missing written contract does not always end the analysis.
Nevada appellate decisions recognize that an agreement between unmarried partners may in some circumstances be implied from conduct.
That is why we may examine how income was pooled, how property was acquired, what tax or business records said, whether both parties signed financial documents, how assets were titled, and how the couple consistently behaved when dealing with major property.
Cohabitation Is Not the Same as a Registered Nevada Domestic Partnership
This distinction can completely change the analysis.
Nevada has a formal domestic partnership system under NRS Chapter 122A. Under NRS 122A.200, registered domestic partners generally receive the same rights, protections and benefits, and are subject to the same responsibilities, obligations and duties under Nevada law as spouses, subject to statutory exceptions.
That can include rights involving property and financial obligations that an ordinary unmarried cohabiting couple does not automatically have.
“Domestic partner” does not simply mean “the person I live with.”
A registered domestic partnership is a formal legal status. Ordinary cohabitation does not automatically create it.
For the full explanation of that separate legal status, see our guide to Nevada domestic partnerships.
Does an Unmarried Partner Automatically Inherit in Nevada?
Ordinary cohabitation does not automatically give an unmarried partner the inheritance rights of a spouse.
Nevada's intestate succession laws provide statutory rights to a surviving spouse and other legally recognized heirs. A boyfriend, girlfriend or long-term cohabiting partner is not automatically converted into a surviving spouse simply because the couple lived together.
This can produce an outcome that feels very different from the relationship itself. A couple may share a home and finances for many years, yet one partner may discover after the other's death that assumptions about inheritance were never put into legally effective documents.
Ownership of jointly titled assets, beneficiary designations, wills, trusts and registered domestic partnership status can all materially affect the result.
What About Medical and Financial Decisions?
Living together also should not be treated as a substitute for proper advance planning.
Nevada law permits a person to appoint an agent through a power of attorney for health-care decisions. Couples who want an unmarried partner to have specific decision-making authority should consider whether appropriate powers of attorney and other estate-planning documents are in place.
What Happens to Children When Unmarried Parents Separate?
A custody case does not become less important because the parents never married.
Once legal parentage is established, Nevada courts decide custody based on the child's best interests under Chapter 125C.
NRS 125C.0035 directs the court to consider factors including the child's needs, the relationship with each parent, parental conflict and cooperation, abuse or neglect, domestic violence, and other circumstances affecting the child's welfare.
For a full custody analysis, this page should support rather than replace our Nevada child custody resource.
Parentage Can Be the First Issue
With unmarried parents, the first dispute may be whether the legal parent-child relationship has been established.
NRS Chapter 126 governs Nevada parentage. For example, NRS 126.051 contains statutory presumptions of paternity, including a presumption when a man and the child's natural mother cohabited for at least six months before the period of conception and continued to cohabit through the period of conception.
Where parentage is disputed, resolving that issue may be necessary before custody and support can be fully determined.
Can a Non-Biological Partner Get Custody or Visitation?
Helping raise a child does not automatically turn a long-term partner into a legal parent.
Nevada law does allow nonparents to seek certain rights in specific circumstances, but the standards are much more demanding than simply showing that the adult loved the child or played an important role in the child's life.
For custody awarded to a nonparent without the parents' consent, NRS 125C.004 requires the court to find that awarding custody to a parent would be detrimental to the child and that custody with the nonparent is required to serve the child's best interest.
Visitation presents a different statutory analysis. Adoption, established parentage, guardianship, prior court orders and the facts of the child's relationship with the adult can all materially change the issue.
Domestic Violence Protections Apply Even If You Are Not Married
A person does not have to be married to qualify for protection under Nevada's domestic-violence laws.
NRS 33.018 includes qualifying acts committed against a spouse or former spouse, a person related by blood or marriage, a person with whom the offender has or had a dating relationship, a person with whom the offender has a child in common, and certain other protected persons.
If an unmarried breakup includes violence, threats, coercion, harassment or another qualifying act, the immediate legal issue may be safety rather than ownership of household property.
For the protection-order process, see our dedicated Nevada restraining order resource.
If you are in immediate danger, call 911.
Property, ownership and financial disputes can be addressed after immediate safety concerns are handled.
What to Do When an Unmarried Cohabiting Relationship Ends
Do not begin by assuming this is “basically a divorce.”
Begin by figuring out what legal relationships actually exist.
Before moving money or property, preserve the evidence that explains how your financial life was structured.
Documents Worth Preserving
- deeds, closing documents and mortgage records;
- bank and investment statements;
- loan agreements and vehicle titles;
- business and tax records;
- written cohabitation or ownership agreements;
- texts or emails discussing major property or financial arrangements;
- records of significant down payments, improvements or capital contributions;
- domestic partnership records, if applicable; and
- existing parentage, custody, support or protection orders.
Do Not Create a Bigger Problem While Trying to Protect Yourself
People sometimes respond to a breakup by emptying an account, selling an asset, changing locks, removing the other person from access, or moving disputed property.
Those actions may feel protective in the moment, but they can complicate the dispute if the ownership or possessory rights are not as clear as expected.
Identify What Type of Case You Actually Have
An unmarried separation may involve a real-estate partition action, contract or equitable property claims, a parentage or custody proceeding, dissolution of a registered domestic partnership, a protection-order matter, or multiple legal issues at the same time.
Correctly identifying the remedy at the beginning is important because a court cannot award a remedy simply because it would have been available if the couple had been married.

Call (702) 433-2889What Nevada Cases Teach Us About Cohabitation Rights
Nevada's published appellate decisions are more useful than generic statements about “palimony” because they show how courts actually analyze property rights between unmarried people.
Hay v. Hay: Unmarried Partners Can Create Enforceable Property Agreements
Hay v. Hay, 100 Nev. 196, 678 P.2d 672 (1984), involved parties who had divorced and then resumed living together for approximately 23 years.
The plaintiff alleged that the couple pooled money, purchased assets and incurred liabilities as though they were a marital community or general partnership.
The Nevada Supreme Court recognized that unmarried people may lawfully contract with one another regarding property and that such an agreement may be express or implied from conduct.
Practical lesson: the absence of a marriage does not prevent a court from examining whether the parties created enforceable property rights between themselves.
Western States Construction v. Michoff: Conduct Can Demonstrate an Implied Agreement
Western States Construction, Inc. v. Michoff, 108 Nev. 931, 840 P.2d 1220 (1992), involved unmarried cohabitants whose financial and business conduct supported an implied property agreement.
The significance of Michoff is not that every long-term couple automatically owns everything equally. It is that courts may examine conduct to determine whether the parties intended to share property rights.
Practical lesson: records showing how a couple actually operated financially may be more important than generalized statements that they “lived like a married couple.”
Sack v. Tomlin: Contributions and Co-Ownership Still Require the Correct Legal Analysis
Sack v. Tomlin, 110 Nev. 204, 871 P.2d 298 (1994), involved unmarried cohabitants and a dispute concerning a residence ultimately titled to the parties as tenants in common.
The Nevada Supreme Court rejected the district court's use of quantum meruit on the facts presented and analyzed the parties' interests as cotenants.
Practical lesson: a court does not simply award whatever percentage feels fair because two unmarried people contributed differently. The form of ownership and the correct legal theory matter.
Gilman v. Gilman: Cohabitation Alone Does Not Automatically End Alimony
Gilman v. Gilman, 114 Nev. 416, 956 P.2d 761 (1998), addressed whether post-divorce cohabitation justified modification or termination of existing alimony.
The Nevada Supreme Court rejected a rule under which cohabitation alone automatically changes support. Instead, the court focused on whether the new living arrangement actually decreased the recipient spouse's financial need.
Practical lesson: the financial effect of the relationship matters more than the label placed on it.
Why Rosenblum Allen Handles Cohabitation Disputes Differently
Unmarried breakups can be harder to analyze than divorces because there is no single proceeding that automatically sorts out every legal issue.
At Rosenblum Allen, we begin by identifying what type of dispute actually exists.
Sometimes the central issue is ownership of a house. Sometimes it is an implied agreement concerning property. Sometimes a financial dispute is secondary to parentage or custody. Sometimes the couple actually registered as domestic partners and a different statutory framework applies. And sometimes a person is asking for a divorce remedy Nevada law simply does not provide to ordinary cohabitants.
Molly Rosenblum has practiced law for more than two decades and handles complex Nevada family-law matters involving property, financial disputes, custody, high-conflict litigation and difficult relationship dynamics.
That experience matters because cohabitation cases rarely arrive in neat legal categories. The facts have to be separated from the assumptions before a strategy makes sense.
Our goal is to identify the strongest legally supportable path early, preserve the evidence that matters, and avoid spending a client's money pursuing a remedy the court cannot award.

Call Rosenblum Allen: (702) 433-2889Frequently Asked Questions About Cohabitation Rights in Nevada
Does Nevada recognize common-law marriage?
No new common-law marriage is created in Nevada merely because two people live together for a certain number of years. NRS 122.010 requires solemnization for marriages created after March 29, 1943. Unmarried partners may still have separate contract, property or equitable rights depending on their circumstances. See our full guide to common-law marriage in Nevada.
If we lived together for 10 years, do I get half of everything?
No. The length of the relationship does not automatically create a 50/50 property right. Ownership may depend on title, contracts, implied agreements, contributions, co-ownership and whether the couple was in a registered domestic partnership.
What if I paid the mortgage but my name is not on the deed?
Your payments may be relevant, but paying the mortgage does not automatically establish a particular ownership percentage. The legal analysis can include the reason for the payments, the parties' agreement, the source of the funds and other evidence showing what ownership arrangement was intended.
What if both of our names are on the house?
Joint tenants and tenants in common may have enforceable co-ownership rights. Nevada partition law may provide a process for determining interests and resolving the property when the owners cannot agree. That is different from automatically dividing the house as community property in a divorce.
Can I get alimony if we were never married?
Ordinary cohabitation does not create an automatic right to Nevada divorce alimony. A separate contractual claim may exist if there was an enforceable support agreement. Registered domestic partnerships are governed differently under Nevada law.
Does moving in with a new partner automatically stop alimony?
No. Cohabitation is not automatically the same as remarriage. Under Nevada law and Gilman v. Gilman, the financial effect of the cohabitation may support modification when it actually decreases the recipient spouse's financial need. The divorce decree or settlement agreement may also contain its own cohabitation terms.
Does an unmarried partner automatically inherit in Nevada?
No. Ordinary cohabitation does not automatically give a partner the intestate inheritance rights of a spouse. Wills, trusts, beneficiary designations, jointly titled assets and registered domestic partnership status can materially affect the result.
Can my boyfriend or girlfriend make me leave the house?
That depends on ownership, lease rights, possessory rights and the facts surrounding occupancy. The right to own a residence and the legal right to remove another occupant are not always the same issue. Avoid self-help measures until you understand the applicable rights.
Do unmarried fathers have custody rights in Nevada?
Yes, but legal parentage may need to be established if it is disputed. Nevada's parentage statutes are found in NRS Chapter 126, and custody is determined under Nevada's custody laws once the parent-child relationship is established.
Can a non-biological partner get custody?
Possibly, but not simply because the person helped raise the child. NRS 125C.004 imposes additional findings before custody may be awarded to a nonparent without parental consent. Parentage, adoption, guardianship, visitation statutes and prior court orders may also affect the analysis.
Is a Nevada domestic partnership the same thing as living together?
No. A Nevada domestic partnership is a formal legal status governed by NRS Chapter 122A. Registered domestic partners generally receive spouse-equivalent rights and obligations under state law, subject to statutory exceptions. See our Nevada domestic partnership guide.
Should unmarried couples have a cohabitation agreement?
A written agreement is particularly worth considering when an unmarried couple plans to buy real estate, share a business, make unequal financial contributions, combine substantial assets or rely financially on one another. Clear documentation can substantially reduce later disputes about what the parties intended.
