In California, a marriage is legally valid only if it meets the requirements set forth in the California Family Code. These laws define who can marry, under what circumstances, and the procedures that must be followed for the marriage to be recognized by the state.
Legal Capacity to Marry
For a marriage to be valid in California, both individuals must have the legal capacity to understand the nature of marriage and give informed, voluntary consent. This starts with age: both parties must be at least 18 years old to marry without court involvement. If either person is a minor, they must obtain a court order and written consent from at least one parent or legal guardian.
Mental capacity is equally important. Under California Family Code section 2210, a marriage is voidable if either party was of unsound mind at the time of the marriage, unless they later regained capacity and continued to live with the other person as a spouse.
To have legal capacity to marry, a person must:
- Understand what marriage is, including its legal and personal responsibilities
- Recognize the rights and obligations involved, such as fidelity and financial support
- Be capable of giving free and voluntary consent
Certain conditions can interfere with this capacity. For instance, individuals with advanced cognitive decline, such as Alzheimer’s disease, may appear cooperative but lack the mental clarity needed for informed consent. Similarly, someone experiencing severe psychiatric symptoms, such as during a psychotic or manic episode, may not fully grasp the nature of the marriage. Developmental disabilities or other cognitive impairments may also prevent someone from understanding what marriage entails. In each case, courts assess whether the individual understood the commitment at the time the marriage occurred.
Temporary incapacity due to intoxication is also considered. If someone was under the influence of drugs or alcohol to the point that they could not understand or consent to the marriage, the union may be subject to annulment.
Mutual Consent
In California, genuine consent is a legal requirement for marriage. If that consent is missing, the marriage may be declared invalid.
Consent is not legally valid if it was obtained through deception about a key aspect of the relationship that would have caused the other person not to marry. Likewise, if a person is forced, threatened, or manipulated into getting married, the consent is not real and the marriage does not meet legal standards.
Incest is Prohibited
California law strictly prohibits incestuous marriages. Under Family Code section 2200:
“Marriages between parents and children, ancestors and descendants of every degree, and between siblings of the half as well as the whole blood, and between uncles or aunts and nieces or nephews, are incestuous, and void from the beginning, whether the relationship is legitimate or illegitimate.”
–California Family Code § 2200:
Incestuous marriages are treated very seriously under California law. California law prohibits marriage between the close relatives mentioned regardless of whether the relationship is through biological ties or adoption.
If two people who are close blood relatives have sexual relations or try to get married, it’s a crime in California, even if they agree to it or don’t know they’re related. Depending on the circumstances and how the case is charged, consequences may include fines, probation, and up to three years in state prison. The offense may be prosecuted as either a misdemeanor or a felony.
Prior Marriages Must Be Dissolved
A person cannot legally marry in California if they are already married. If someone was lawfully married anywhere in the world, California will recognize that marriage as valid and, therefore, will not recognize a new marriage unless the previous one has been legally dissolved through divorce or annulment, or death of the prior spouse. Both must be unmarried (or legally divorced, widowed, or have an annulment) before entering into a new marriage. Being legally separated is not sufficient.
If someone marries in California while still legally married to someone else, the new marriage is void from the beginning and may result in criminal prosecution for bigamy under Penal Code section 281.
However, if the new spouse entered the marriage in good faith, unaware of the prior marriage, they may have legal protections under the putative spouse doctrine, which grants certain rights as if the marriage were valid.
Proper Procedures Must Be Followed
Even when a couple is legally allowed to marry, HOW the marriage takes place is vital for determining the validity of the marriage. For a marriage to be legally valid in California, couples must do more than exchange vows. They must follow the legal requirements set by the state.
Must Be Officiant-Led
California does not permit self-solemnized marriages. Couples cannot simply declare themselves married. The marriage also cannot be officiated by just any person. The ceremony must be conducted by someone legally authorized to perform marriages in California. This includes judges, clergy members such as priests or rabbis, and select public officials.
The only exception to this rule applies to certain religious groups, such as Quakers or similar faiths, where self-solemnization is part of their religious tradition and follows specific internal procedures recognized by the state.
No Marriage by Proxy
Additionally, both parties must be physically present at the ceremony. Marriage by proxy is not allowed, except in rare circumstances involving military service, as outlined in Family Code section 420(b). California emphasizes the importance of personal presence and proper authority in creating a valid marital union.
Marriage License Requirements
A symbolic or spiritual ceremony without a marriage license has no legal effect. Couples must obtain a valid marriage license from a California county clerk’s office before the ceremony takes place.
After the ceremony, the license must be signed by both parties, the officiant, and at least one witness (two witnesses are required for public licenses). The license is valid for 90 days from the date of issuance and must be returned to the county clerk or recorder to be officially registered.
No Common Law Marriage
Common law marriage is a legal concept where a couple is considered legally married without having gone through a formal ceremony and obtained a marriage license or certificate.
Instead, the couple gains marital status simply by living together for a certain period, intending to be married and presenting themselves publicly as a married couple (e.g., using the same last name, filing joint taxes, referring to each other as “husband” or “wife”).
While common law marriage is recognized in some U.S. states, California does NOT. But there’s one exception. If a couple validly formed a common law marriage in a state that recognizes it, and later moved to California, Then California will honor that marriage under the Full Faith and Credit Clause of the U.S. Constitution.
