An annulment in California is a court order declaring that a marriage was never legally valid. Unlike a divorce, which ends a valid marriage, an annulment treats the union as if it never happened.
Annulments are far less common than divorces because the legal grounds are narrow and the burden of proof falls on the person requesting one. Still, for the right situation, getting an annulment can be the cleanest path forward.
This guide explains the legal grounds, the annulment process, the strict time limits, and what happens to property and children. It is educational information, not legal advice.
What an Annulment in California Really Means
When a marriage is annulled, California law treats both parties as though they were never legally married. The marriage is erased rather than dissolved.
That distinction matters. Because the marriage is considered legally invalid, the usual rules for dividing community property and awarding spousal support generally do not apply.
To get an annulment, one or both parties must prove that the marriage qualifies under a specific legal ground recognized by California law. A general feeling that the marriage was a mistake is not enough.
Annulment vs. Divorce vs. Legal Separation
A divorce ends a marriage that was valid from the start and divides the couple’s community property. After a divorce, both people are single again.
A legal separation lets a couple live apart and divide responsibilities while remaining legally married. An annulment does the opposite of both: it says no valid marriage ever existed.
Because the standards are so different, choosing between these options depends heavily on your facts. Many people who believe they qualify for an annulment ultimately proceed with divorce instead.
Legal Grounds for Annulment in California
California recognizes two categories of invalid marriages: void marriages and voidable marriages. The legal grounds for each are set out in the Family Code.
Void Marriages
A void marriage is never legally valid, even without a court order. There are two grounds: incestuous marriages between close blood relatives, and bigamous marriages where one spouse was already legally married to someone still living.
Even though no judgment is technically required, many people still file for an annulment to get a clear court record confirming the marriage was invalid.
Voidable Marriages
A voidable marriage is valid until a judge annuls it. These grounds for annulment require proof and include several situations.
The recognized grounds are: an underage marriage where one party was younger than 18 without court approval or parental consent; a prior existing marriage where a missing spouse was believed dead; unsound mind, where one person lacked the mental capacity to understand the marriage; fraud that goes to the heart of the marriage; force or threats; and physical incapacity to consummate the marriage.
Fraud is the most commonly cited ground, but it must involve something fundamental, such as marrying only for immigration benefits or concealing an inability or refusal to have children.
Time Limits: Why Four Years Matters
California sets strict deadlines to file for an annulment, and many run for four years. Missing the window usually means you must pursue a divorce instead.
For an underage marriage, the petition must be filed within four years of turning 18. For fraud, the clock runs four years from when the fraud was discovered, and for force or physical incapacity, generally four years from the marriage date.
An annulment based on unsound mind may be sought at any time before the death of either party. Because these rules are unforgiving, acting quickly is important.
How to File for an Annulment in California
The legal process begins by filing a Petition (Form FL-100) and selecting “nullity of marriage” as the type of case. You can find related paperwork on our family law forms page.
After filing, you must formally serve your spouse so they have a chance to respond. The annulment process then moves toward a court hearing.
At the hearing, the petitioner carries the burden of proving the legal grounds with evidence and sometimes testimony. Because annulments are harder to win than divorces, preparation is essential.
What Happens to Property, Support, and Children
Since an annulled marriage is treated as if it never existed, community property division and spousal support generally do not apply the way they would in a divorce.
California protects an innocent partner through the “putative spouse” doctrine. If you genuinely believed your marriage was valid, a court can divide property fairly as quasi-marital property.
Children are fully protected. A child born during an annulled marriage remains legitimate, and the court still addresses child custody, visitation, and child support.
Do You Need a Family Law Attorney?
Annulment cases turn on narrow legal grounds and tight deadlines, so the stakes of a misstep are high. An experienced family law attorney can assess whether your marriage qualifies.
If it does not, the attorney can guide you toward divorce and explain how issues like spousal support would be handled instead. Either way, you avoid wasting time on the wrong path.

Frequently Asked Questions
Is an annulment faster than a divorce in California?
Not necessarily. While there is no six-month waiting period, you must prove specific legal grounds, which can make an annulment more complex than an uncontested divorce.
Does a short marriage automatically qualify for annulment?
No. A very short marriage does not qualify on its own. You still need a recognized legal ground such as fraud, force, or lack of mental capacity.
Can I get spousal support after an annulment?
Generally no, because the marriage is treated as if it never existed. A recognized putative spouse may be an exception.
Are children from an annulled marriage considered legitimate?
Yes. California law protects these children, and custody and support are decided just as they would be in a divorce.
