Does California Have Common Law Marriage? (2026)

Understanding What Common Law Marriage Means

Common law marriage is a legal concept where a couple becomes spouses without a license or ceremony. Typically, the partners must live together, present themselves publicly as married, and intend to be married.

Only a handful of states still allow couples to form a common law marriage today. Each of those states sets its own rules regarding the specific requirements for cohabitation and what counts as holding themselves out as a married couple.

California's Stance on Common Law Marriage

California does not permit common law marriage. Under California Family Code Section 300, marriage requires the consent of both parties, a license, and solemnization. Simply living together – no matter how long – does not create a marriage.

So if you stay in California with your partner for 10, 20, or even 40 years without a license, the state does not view you as legally married. This affects:

• Property division, if you separate, which could require the guidance of a property division lawyer
• Spousal support eligibility
• Inheritance rights if a partner passes away without establishing a formal will
• Access to a partner's benefits

There is one narrow exception. Under California Family Code Section 2251, if you believed in good faith that your marriage was valid but it turned out to be void or voidable, a court must declare you a "putative spouse" and divide property as "quasi-marital property."

Recognition of Out-of-State Common Law Marriages

California may recognize a common law marriage that was validly formed in another state. California Family Code Section 308 states that a marriage contracted outside California is valid here if it was valid where it was created.

In practice, that means if you and your partner met every requirement for a common law marriage in a state that allows it – such as Texas, Colorado, or Iowa – California will generally treat you as married. You may need to prove that the relationship satisfies that state's specific rules.

Legal Rights and Protections for Unmarried Couples

Unmarried partners in California still have options to secure their legal standing. When evaluating a domestic partnership vs marriage, it is helpful to know that registered domestic partnerships—defined under California Family Code Section 297—let two adults in a committed relationship register with the state, provided they are not married to someone else, not closely related by blood, and are legally capable of consenting.

Under California Family Code Section 297.5, registered domestic partners receive the same rights, protections, and responsibilities as spouses. That covers property, support, and health care decisions.

Couples who do not register can still protect themselves through:

• Written cohabitation agreements
• Joint property titles and beneficiary designations
• Wills and powers of attorney
• Parenting agreements for shared children

Palimony and Cohabitation Agreements in California

California recognizes that unmarried partners can form contracts about money and property. California Civil Code Section 1619 explains that a contract may be express or implied, and Section 1621 confirms that an implied contract is shown through the parties' conduct.

This is the foundation for "palimony" – financial support claims between unmarried partners based on an agreement, whether spoken, written, or implied by the couple's behavior. Understanding what a cohabitation agreement is and drafting a clear written contract is generally the strongest way to avoid disputes later. It can spell out who owns what, how expenses are shared, and what happens if the relationship ends.
