California is famous for its community-property laws, so describing it as a common-law state can sound contradictory. Both descriptions are possible—but they concern different parts of the law.
California uses a common-law legal system, meaning judges rely on legislation and earlier court decisions. Yet it does not allow couples to form common-law marriages simply by living together, even if they have spent decades in the same home. California also recognizes valid marriages established elsewhere and offers a separate system of registered domestic partnerships.
For married couples, California generally treats earnings and assets acquired during marriage as community property. Its divorce rules usually require an equal division of the community estate. Unmarried partners do not receive those rights automatically, although they may enforce agreements about shared assets.
Understanding California’s Common-Law Legal System
California’s courts are part of the American common-law tradition, which uses judicial precedent alongside statutes. A decision from the California Supreme Court can establish a binding interpretation that other state courts must follow in comparable cases.
California Civil Code § 22.2 adopts English common law as a rule of decision so long as it is consistent with the federal and California constitutions and state laws. The Legislature has also enacted detailed codes governing marriage, property, contracts, and inheritance.
That combination matters: common-law reasoning does not override an express statute. The fact that California follows precedent therefore tells you nothing by itself about whether an unmarried partner receives spousal benefits.
California differs from states with civil-law traditions, such as Louisiana, but its marriage and property rules must be examined separately.
Is California a Common-Law Marriage State?
No. California does not permit new common-law marriages to arise within the state. The state abolished that method of marriage formation in 1895, a historical point acknowledged by the California Supreme Court in Marvin v. Marvin (1976).
Living together for five years, twenty years, or a lifetime does not change that answer. Filing taxes from the same address, sharing children, or calling each other husband and wife cannot replace a legally valid marriage.
What Is Required to Get Married in California?
Under California Family Code § 300, mutual consent alone does not establish a marriage. The usual process requires a marriage license and legally authorized solemnization. California provides public and confidential marriage-license procedures, each with its own requirements.
For most couples, the steps are straightforward:
- Obtain the proper marriage license from an authorized county office.
- Complete a legally recognized ceremony with an authorized officiant.
- Ensure the paperwork is registered to produce the marriage record.
A costly celebration is unnecessary. Special statutory procedures may apply in limited situations, so couples should follow the instructions for their particular license.
Does California Recognize Common-Law Marriages From Other States?
Yes, if they were validly established under the law of the place where they were formed. California Family Code § 308 states that a marriage contracted outside California that is valid there is valid in California.
For example, partners who legally formed a common-law marriage while living in a state that permits it do not ordinarily lose their marital status simply because they move to Los Angeles or San Diego.
Still, the couple must prove the marriage existed under the other state’s law. Time spent together in California cannot be used to create a California common-law marriage retroactively.
Are Registered Domestic Partners the Same as Common-Law Spouses?
No. A registered domestic partnership is a separate legal status created through registration. Under Family Code § 297.5, registered domestic partners generally have the same rights and responsibilities as spouses under California law, including important property and inheritance protections.
This does not make every unmarried couple a registered domestic partnership. Registration matters, and federal tax treatment can differ from marriage.
Is California a Common-Law Property State?
No. California is a community-property state, not a separate-property state. Family Code § 760 generally treats property acquired by a married person while domiciled in California during marriage as community property, unless a statutory exception applies.
Community property commonly includes employment income, savings from marital earnings, homes bought with those earnings, and the marital portion of retirement benefits. Both spouses generally have equal ownership interests in the community estate, even when one earns more than the other.
What Counts as Separate Property in California?
Under Family Code § 770, property owned before marriage, gifts or inheritances received by one spouse, and income from such separate property ordinarily remain separate. Property and earnings acquired after the legally established date of separation can also have separate-property treatment.
Problems arise when separate funds are mixed with community funds or used to buy property titled jointly. Documentation and tracing may determine whether an asset is separate, community, or partly both.
How Does California Divide Property in a Divorce?
California has a stricter default rule than states that simply divide property according to overall fairness. Family Code § 2550 generally requires an equal division of the community estate unless spouses agree otherwise or a statutory exception applies.
That does not require selling every asset and splitting the cash. One spouse may keep the house while the other receives other assets or an equalizing payment. Separate property is ordinarily retained by its owner, and community debts must also be addressed.
What Property Rights Do Unmarried Couples Have?
Unmarried couples who are not registered domestic partners do not receive automatic community-property rights. But California recognizes enforceable agreements about property and financial arrangements.
In Marvin v. Marvin (1976), the California Supreme Court held that courts can enforce qualifying express or implied agreements between unmarried partners. Under appropriate facts, other remedies involving ownership or contributions may also be available.
This does not turn the relationship into a marriage, and financial support is not automatically owed simply because the couple lived together.
Key Takeaways and Estate Planning Tips
- Confirm legal status. Marriage, registered domestic partnership, and cohabitation have different consequences.
- Put property agreements in writing. Record how partners will share purchases, mortgage costs, and debts.
- Keep financial records. Preserve evidence identifying separate funds and shared contributions.
- Create a will and review beneficiaries. Unregistered unmarried partners generally do not inherit automatically as spouses.
- Prepare healthcare directives and powers of attorney. Name trusted decision-makers rather than assuming cohabitation provides authority.
Conclusion
California is a common-law legal-system state but not a common-law marriage state. It is also a community-property state, with generally equal division of the community estate at divorce. Recognized out-of-state marriages and registered domestic partnerships are important exceptions to assumptions about unmarried relationships.
