Common Law Marriage in California: Is It Recognized? (2026)

California does not recognize common law marriage. The state has required a marriage license and solemnization for a valid marriage since 1895, and California Family Code section 300 codifies that requirement today. However, California will recognize a common-law marriage that was validly formed in another state under Family Code section 308.

Does California Recognize Common Law Marriage?

No. California does not permit couples to form a common-law marriage within the state. California Family Code section 300 states that marriage is a personal relation arising out of a civil contract between two persons, and that a valid marriage requires consent of the parties capable of entering into it, and a solemnization as provided in Part 3 of the Family Code. Section 300 does not provide any alternative path to marriage without a license and ceremony. California courts have consistently applied this rule: without a marriage license and solemnization, no valid California marriage exists, regardless of how long a couple has lived together, how they have held themselves out to the public, or what they believed about their legal status.

This rule has been in place since 1895. California abolished common-law marriage formation far earlier than most states that have since followed suit, and the Legislature has not revisited the issue. As of June 2026, no bill to restore common-law marriage recognition is pending in the California Legislature.

Why California Stopped Recognizing Common Law Marriage in 1895

California recognized common-law marriages under general common-law principles in the nineteenth century, but the Legislature eliminated that recognition in 1895 by requiring a license and ceremony for all valid marriages. The rationale was administrative clarity: requiring a formal record of every marriage reduces fraud, protects inheritance rights, simplifies estate administration, and protects spouses who might otherwise be unaware that a common-law marriage had been asserted against them.

California courts have applied the 1895 rule consistently in the intervening 130 years. The California Supreme Court and Courts of Appeal have repeatedly declined to create judicial exceptions for couples who believed, incorrectly, that long cohabitation created a valid marriage. If a couple lived together in California for decades and held themselves out as married but never obtained a license, California courts treat them as unmarried.

This does not mean that long-term cohabiting couples in California have no legal recourse. California courts have developed the "Marvin doctrine," arising from the California Supreme Court's decision in Marvin v. Marvin (1976) 18 Cal. 3d 660, which allows cohabiting partners to seek remedies based on contract or equity when a relationship ends. A Marvin claim is not a marriage claim and does not create marital property rights, but it can provide a remedy for one partner who contributed economically to the other's benefit. A Marvin claim is entirely separate from common-law marriage and requires its own legal analysis.

Out-of-State Common Law Marriages: California Recognizes Them

Although California does not allow new common-law marriages to be formed here, California Family Code section 308 provides that a marriage contracted outside California that would be valid by the laws of the jurisdiction in which the marriage was contracted is valid in California. This means that a couple who validly formed a common-law marriage in Colorado, Texas, Iowa, Kansas, Montana, Rhode Island, the District of Columbia, or any other jurisdiction that recognizes common-law marriage will be treated as legally married in California if they later move here.

The Full Faith and Credit Clause of the United States Constitution (Art. IV, § 1) reinforces this principle by requiring states to give effect to the public acts, records, and judicial proceedings of other states. Courts in California have applied this rule to recognize out-of-state common-law marriages in a range of family law contexts, including divorce, property division, spousal support, inheritance, and insurance beneficiary disputes.

To benefit from section 308, the couple must have satisfied all the requirements for a valid common-law marriage under the law of the state where they lived when the marriage was formed. The requirements vary by state, but generally include: legal capacity to marry (both parties unmarried and of age), a present mutual agreement to be married (not merely to live together), cohabitation in the recognizing state, and holding out to the public as a married couple. Meeting California's informal-relationship standards is not enough; the couple must have met the specific requirements of the state whose law governs the formation.

California Registered Domestic Partnerships: Not the Same as Common Law Marriage

California offers registered domestic partnerships (RDPs) under Family Code sections 297 through 299.6, which provide many of the same state-law rights and responsibilities as marriage. An RDP is available to any two adults who meet Family Code section 297's requirements: neither person is already married to someone else or in another undissolved domestic partnership, the two are not related by blood in a way that would bar marriage between them, both are capable of consenting, and both are at least 18 years old (with a narrow court-approval path for a minor under section 297.1). Eligibility no longer turns on the couple's sex or age beyond 18, unlike the earlier rule that limited RDPs mainly to same-sex couples or to opposite-sex couples where one partner was 62 or older.

A registered domestic partnership is a formal legal status that requires filing a Declaration of Domestic Partnership with the California Secretary of State. It is not informal and it is not automatic. An RDP does not operate as a common-law marriage, and it is a separate legal institution governed by its own statutes. Couples in a long-term committed relationship in California who want legal recognition of that relationship must take an affirmative step: either marry formally or register as domestic partners. Neither status arises automatically from cohabitation or from calling each other spouses.

The distinction matters for purposes of federal benefits, immigration, and portability to other states, because federal law and other states' laws may not recognize an RDP as equivalent to marriage in all contexts.

How to Prove a Common Law Marriage in California

Because California does not form common-law marriages, the question of proof arises only when a couple claims that a valid common-law marriage was formed in another state before they relocated to California. In those cases, California courts apply the law of the state where the marriage was allegedly formed to determine whether the requirements were met.

Evidence that courts consider when evaluating whether a valid common-law marriage was formed in another state typically includes:

• Joint tax returns filed as "married filing jointly" or "married filing separately"
• Mortgage documents, lease agreements, or bank accounts listing both persons as spouses
• Life insurance policies or retirement plan beneficiary designations naming the other person as "spouse"
• Affidavits or declarations from family members, friends, or employers attesting that the couple held themselves out as married
• Records showing the couple used the same last name or introduced each other as husband and wife
• Medical or hospital records identifying the other person as "spouse"

None of these items is individually conclusive. Courts look at the totality of the evidence to determine whether the couple genuinely agreed to be married and publicly represented themselves as married under the law of the originating state. The stronger and more consistent the documentary record, the stronger the claim.

How a Common Law Marriage Ends in California

A validly formed common-law marriage, whether formed in California before 1895 or in another state and brought to California, can only be dissolved by formal divorce. There is no such thing as a common-law divorce. A couple who formed a valid common-law marriage and later separated cannot simply walk away from the marriage; each partner remains legally married until a court dissolves the marriage by judgment.

This matters practically in several ways. If a common-law spouse remarries without first obtaining a divorce, that second marriage is void under California law. The former common-law spouse retains rights under California community property law during any period the married couple lived in California, including rights in property acquired during that period. And upon the death of one common-law spouse, the surviving spouse has inheritance rights that other heirs cannot simply override.

The divorce process for a common-law marriage follows the same California Family Code rules as any other divorce: filing a petition for dissolution, service, a six-month waiting period, property and support proceedings, and a final judgment. The fact that the marriage was not licensed does not create a shortcut to dissolving it.

The 7-year myth. Many people believe that living together for seven years automatically creates a common-law marriage. This is false everywhere in the United States. No state has ever required a specific number of years of cohabitation as the basis for a common-law marriage. The myth likely originates from a misunderstanding of statutes of limitations or adverse possession principles. In California, cohabiting for any length of time, whether seven years or thirty, does not create a marriage without a license and ceremony.
