No number of years creates a common law marriage in California. The state does not recognize common law marriage and never has, so living together for two years, seven years, or twenty years does not make you legally married. If you want the legal status of a spouse, you need a marriage license and a ceremony, or in some cases a registered domestic partnership.
Why Time Alone Never Creates a Marriage Here
California Family Code § 300 sets the requirements plainly: a valid marriage takes the consent of both parties, a marriage license, and a solemnization ceremony.1California Legislative Information. California Code FAM 300 – Validity of Marriage Consent by itself is not enough. There is no threshold of cohabitation, shared finances, or public reputation that substitutes for the license and ceremony.
The “seven-year rule” is a myth. No state uses seven years as a trigger, and California does not allow common law marriage at any duration. Couples who assume they are common-law married after a long relationship have no automatic right to community property division, spousal support, or inheritance from each other. Those rights come from marriage, domestic partnership, or a written agreement, not from time.
The One Situation Where a Common Law Marriage Counts in California
California will recognize a common law marriage that was validly formed in a state that allows one. Family Code § 308 provides that a marriage contracted outside California is valid here if it was valid where it was formed.2California Legislative Information. California Code FAM Division 3, Part 1, Section 308
To qualify, your relationship had to meet that state’s requirements while you were actually living there. A vacation or a brief visit does not do it. States that recognize common law marriage typically require an agreement between the partners to be married, cohabitation in that state, and holding yourselves out publicly as a married couple. A handful of jurisdictions still allow it, including Colorado, Iowa, Kansas, Montana, New Hampshire (for inheritance only), Oklahoma, Rhode Island, South Carolina, Texas, Utah, and the District of Columbia, each with its own rules.
If you formed a valid common law marriage in one of those places and then moved to California, you are treated as married here. California’s community property rules, support laws, and divorce procedures apply, and you cannot simply walk away. Ending the relationship requires a formal divorce.
What Protects Unmarried Couples Who Live in California
If you have lived together in California for years and want legal recognition, you have real options. What you do not have is any status that appears automatically after a certain amount of time.
Registered Domestic Partnership
California allows any two adults in a committed relationship to register as domestic partners with the Secretary of State under Family Code § 297.3California Legislative Information. California Code FAM 297 – Domestic Partner Registration Both partners must be at least 18, unmarried, not in another active partnership, and not related in a way that would prevent marriage. Registered partners receive nearly all the same state-level rights as married spouses, including community property treatment, spousal support if the partnership ends, hospital visitation, and medical decision-making authority.4Justia Law. California Code FAM 297-297.5 – Definitions Federal benefits tied to marriage, such as Social Security survivor payments, are not included. If federal recognition matters, marriage is the stronger choice.
Confidential Marriage
Couples already living together as spouses can apply for a confidential marriage license. It requires no witnesses at the ceremony, and the marriage record is not publicly accessible.5California Department of Public Health. Types of Marriage Licenses Both parties must be at least 18 and cohabiting at the time of application. A ceremony is still required, but it can be private. For people who feel already married in every practical sense and want the legal status without a public event, this route delivers the full protection of marriage.
Cohabitation Agreement
If you do not want to marry or register, a written cohabitation agreement is the most effective way to protect your finances. These are sometimes called Marvin agreements, after the 1976 California Supreme Court decision in Marvin v. Marvin, which held that unmarried partners can make enforceable contracts about property and support. Where no written agreement exists, courts can look at conduct to find an implied one, but proving an oral or implied arrangement years later is slow and uncertain.6Justia Law. Marvin v. Marvin A written agreement can cover who owns what, how expenses are shared, what happens to jointly purchased assets on separation, and whether either partner will receive support.
Wills, Trusts, and Powers of Attorney
California’s intestacy laws exclude unmarried partners entirely. If you die without a will, your assets pass to blood relatives, not to the person you shared your life with. A will lets you name your partner as a beneficiary. A living trust does the same and avoids probate. Durable powers of attorney for financial matters and an advance healthcare directive let your partner act for you if you become incapacitated. Without those documents, medical and financial decisions fall to your legal next of kin, and your partner has no authority.
The Putative Spouse Exception
California has a narrow doctrine for people who genuinely believed they were married when they were not. Under Family Code § 2251, a court can declare someone a “putative spouse” if it finds the person held a good-faith belief the marriage was valid. A putative spouse can ask the court to divide property acquired during the relationship as “quasi-marital property” under the community property rules.7California Legislative Information. California Code FAM 2251 – Status of Putative Spouse
This is not a workaround for couples who simply lived together. It applies when someone honestly thought a ceremony or license made them married and later learns it did not, for example because the license was defective or a prior marriage was never dissolved. Someone who knows there was never a ceremony or license generally cannot use this doctrine.
The bottom line: in California, time in a relationship, no matter how long, does not create marital rights. Those rights come from steps you take deliberately, and the sooner you take them, the more they protect you.
