COMMON LAW MARRIAGE IN CALIFORNIA
Living together for years does not make a couple legally married in California. But a valid common law marriage formed somewhere else may still be recognized after a move to California.
QUICK ANSWER
Does California Have Common Law Marriage?
No. California does not allow couples to create a common law marriage simply by living together, no matter how long the relationship lasts. Sharing a home, using the same last name, combining finances, or calling each other spouses does not make a couple legally married in California.
There is an important exception: California generally recognizes a common law marriage that was validly established in another state or country. If that applies, marital status can affect property, support, inheritance, benefits, and whether a divorce is required to end the relationship.
THE BOTTOM LINE
Key Takeaways
- There is no seven-year, 10-year, or other time rule that creates a common law marriage in California.
- A valid common law marriage formed somewhere else may remain valid after the couple moves to California.
- Unmarried partners do not automatically receive California’s community property or spousal support rights.
- Contracts, property titles, financial records, and other evidence may still give an unmarried partner a claim.
- Marriage, registered domestic partnership, and cohabitation are different legal relationships.
- A parent’s rights and duties do not depend on whether the parents were married, although legal parentage may need to be established.
CALIFORNIA LAW
Does California Recognize Common Law Marriage?
California does not recognize a common law marriage created within California. Under California Family Code Section 300, consent alone is not enough to create a marriage. A couple generally must obtain a marriage license and have the marriage legally solemnized.
That means you do not become married in California simply because you:
- Have lived together for many years
- Share bank accounts or expenses
- Own a home together
- Have children together
- File documents using the same address
- Refer to each other as husband, wife, or spouse
- Wear rings or use the same last name
Those facts may matter in a contract, property, parentage, or benefits dispute, but they do not create a California common law marriage.
COMMON MYTH
How Many Years Is Common Law Marriage in California?
There is no seven-year rule.
No amount of time creates a common law marriage in California. A relationship lasting seven, 10, 20, or more years is still not a marriage under California law unless the couple completed the legal marriage process or formed a valid marriage somewhere else.
THE IMPORTANT EXCEPTION
When Will California Recognize a Common Law Marriage From Another State?
California generally recognizes a common law marriage if it was valid where it was created. California Family Code Section 308 says a marriage formed outside California is valid in California if it was valid under the law of the place where it was formed.
For example, a couple may have established a valid common law marriage while living in a state that permits it and later moved to California. Moving does not usually erase that marriage. If California recognizes the marriage, the couple generally must get divorced to legally end it.
The difficult part is often proving that the marriage met the other state’s requirements because each state has its own rules. Living together may be only one factor, and some states no longer allow new common law marriages.
PROVING YOUR STATUS
How Can You Prove an Out-of-State Common Law Marriage?
The evidence depends on the law of the state where the marriage allegedly began. It may include:
No single document automatically proves every common law marriage. The court must apply the law of the place where the relationship was formed to the facts and evidence. That makes the timeline of where you lived, when you lived there, and what you both intended especially important.
UNMARRIED PARTNERS
What Rights Do Unmarried Couples Have in California?
Unmarried partners do not automatically receive the same rights as spouses. California’s community property and spousal support laws generally apply to marriages and registered domestic partnerships, not to couples who only live together.
Still, “not married” does not always mean “no rights.” A partner may have a claim based on:
- A written or verbal agreement
- An agreement shown by the couple’s conduct
- The name or names on a deed, account, or other title document
- Contributions toward a home, business, or other asset
- General contract, property, or fairness-based legal principles
- Putative spouse rights in qualifying circumstances
The type of claim depends on the facts. Some disputes between unmarried partners belong in civil court rather than family court.
PROPERTY & FINANCES
What Happens to Property When an Unmarried Couple Separates?
California does not automatically split an unmarried couple’s property 50/50. Community property rules generally do not apply simply because partners lived together or shared expenses.
Instead, ownership may depend on title, contracts, each partner’s financial contributions, and what the partners agreed to do. Common disputes involve:
- A home titled in one partner’s name even though both helped pay the mortgage
- A jointly owned home when one person paid more of the down payment or expenses
- Money invested in a partner’s business
- Joint accounts or large purchases
- Personal property bought during the relationship
- Debts one partner took on for shared expenses
Why Marvin v. Marvin matters
The California Supreme Court held that agreements between unmarried partners may be enforceable. A court may consider a written agreement, verbal promise, or agreement shown by conduct if it is otherwise lawful. A long relationship by itself does not guarantee either partner part of the other’s property.
FINANCIAL SUPPORT
Can an Unmarried Partner Receive Alimony or “Palimony” in California?
An unmarried partner does not have an automatic right to spousal support. California spousal support laws generally protect spouses and registered domestic partners when their legal relationship ends.
“Palimony” is an informal term, not a separate type of California family court support. It usually describes a financial claim based on an agreement between unmarried partners. For example, one partner may claim that the other promised ongoing support in exchange for leaving a job, caring for the household, or contributing to a shared life.
To succeed, the person seeking payment must prove a valid legal basis for it. The length of the relationship and financial dependence may be relevant evidence, but neither creates a right to support on its own.
KNOW THE DIFFERENCE
Common Law Marriage, Domestic Partnership, and Cohabitation: What Is the Difference?
These terms are often mixed together, but they do not mean the same thing.
| Relationship | How it begins | California recognition | Possible rights when it ends |
|---|---|---|---|
| Common law marriage formed in California | It cannot be created under current California law. | No | No automatic marital rights based only on cohabitation. |
| Valid common law marriage formed elsewhere | The couple meets the law of a jurisdiction that permits it. | Generally, yes | Divorce, property division, and support rules may apply. |
| California registered domestic partnership | The couple files a Declaration of Domestic Partnership and meets state requirements. | Yes | California generally gives registered partners the same state-law rights and duties as spouses. |
| Cohabitation | The couple lives together without marrying or registering. | Yes, as a living arrangement—not as a marriage. | Rights depend on title, contracts, contributions, parentage, and other facts. |
Under California Family Code Sections 297 and 297.5, registered domestic partners generally receive the same rights, protections, responsibilities, and duties under California law as spouses. Federal treatment can differ, so couples should not assume a domestic partnership and a marriage have identical tax or benefit consequences.
GOOD-FAITH BELIEF
What Is a Putative Spouse in California?
A putative spouse is someone who honestly believed they were legally married but later learned the marriage was invalid. For example, one person may discover that their partner was still legally married to someone else when the ceremony took place.
Under California’s putative spouse laws, a court may divide qualifying property acquired during the attempted marriage. A court may also award financial support in some circumstances. Putative spouse rights do not apply simply because a couple lived together or viewed their relationship as similar to a marriage.
CHILDREN & PARENTAGE
What Happens When Unmarried Parents Separate?
Parents can ask for custody, parenting time, and child support whether or not they were married. The key question may be whether legal parentage has been established, not whether the parents had a common law marriage.
Once parentage is established, a court can make orders about custody, parenting time, and child support.
INHERITANCE & BENEFITS
What Happens If an Unmarried Partner Dies?
A cohabiting partner generally does not receive the automatic inheritance rights given to a surviving spouse or registered domestic partner. The surviving partner may inherit through a will, trust, beneficiary designation, joint ownership arrangement, or another valid estate-planning tool. A valid common law spouse from another state may have spousal rights, but the marriage may first need to be proved.
Long-term partners should review how their home, bank accounts, retirement benefits, life insurance, medical decisions, and estate documents are set up. Living together for many years does not replace those documents.
PLAN AHEAD
How Can Unmarried Couples Protect Themselves?
Couples who do not plan to marry can still put important agreements in writing. A cohabitation agreement may address:
WHEN TO GET LEGAL GUIDANCE
When Should You Speak With a California Family Law Attorney?
It may be worth getting legal advice before taking action if:
- You lived together in a state that recognizes common law marriage.
- One partner says you were married and the other disagrees.
- You are separating after buying a home or building a business together.
- You gave up income or contributed money based on a promise of support or ownership.
- You have children and parentage, custody, or support is unresolved.
- Your partner died and your right to inherit or receive benefits is disputed.
- You signed—or are being asked to sign—a property or separation agreement.
Small details can change which law applies and which court can hear the dispute. Modern Family Law’s California family law attorneys can help identify the questions that need answers, review the documents that matter, and explain your options.
FIND OUT WHERE YOU STAND
A Long Relationship Can Still Raise Important Legal Questions
When a long relationship ends, it can be unsettling to learn that the law may not view it the way you did. You may still have property, contract, parentage, or support issues worth addressing—and it helps to understand them before accounts are closed, property is sold, or agreements are signed.
COMMON QUESTIONS
Frequently Asked Questions About Common Law Marriage in California
Does California have common law marriage?
No. Couples cannot create a common law marriage while living in California. California may, however, recognize a common law marriage that was validly created in another state or country.
Are you legally married after living together for seven years in California?
No. California has no seven-year rule for common law marriage. No amount of cohabitation creates a marriage in the state.
Can I be on my partner’s health insurance if we are not married?
Possibly. Eligibility depends on the employer or insurance plan. Some plans cover domestic partners or qualifying unmarried partners, while others limit coverage to spouses and dependents. Ask the plan administrator what proof is required and whether tax consequences may apply.
Do unmarried couples have community property rights in California?
Not automatically. Community property rules generally apply to spouses and registered domestic partners. An unmarried partner may still have rights based on title, a contract, financial contributions, or another legal claim.
Can I get half the house if my name is not on the deed?
Not automatically, but the deed may not end the inquiry. Payments, written or verbal agreements, and the reason the home was titled in one name may matter. These disputes depend heavily on the evidence and may need to be handled in civil court.
Can I receive spousal support after a long-term unmarried relationship?
There is no automatic right to spousal support based only on living together. A person may have a contract-based financial claim, sometimes called palimony, if they can prove a valid promise or agreement.
Do we need a divorce if our common law marriage began in another state?
If the marriage was validly formed in another state and is recognized in California, you generally need a divorce to legally end it. Simply separating does not end the marriage.
Is a domestic partnership the same as common law marriage in California?
No. A California domestic partnership is a registered legal status. Common law marriage is a different way of forming a marriage that California itself does not allow. Registered domestic partners do receive many of the same rights and duties as spouses under California law.
Does having a child together make us common law married?
No. Having a child together does not create a marriage. Once legal parentage is established, each parent may have rights and responsibilities involving custody, parenting time, and child support.
