Annulment vs. Divorce in California: What Each One Actually Does to Your Marriage

Most people searching for "annulment" in California arrive with a version of the same question: does their situation qualify, and is it somehow simpler than divorce? The confusion is understandable — the word "annulment" is everywhere in everyday conversation, but California's statutes don't actually use it. The law calls it a nullity of marriage, and the grounds are considerably narrower than most people expect. Whether you're weighing your options early on or trying to understand what a friend or attorney has told you, this article explains what each proceeding actually does under California law, where they differ in practical terms, and how they move through a San Diego court.

The short version: a divorce ends a marriage that legally existed; a nullity declaration treats the marriage as though it never had legal existence at all. That distinction has real consequences for property, support, and what the petitioner must prove.

What California Law Actually Means by 'Annulment'

California's Family Code doesn't use the word "annulment" at all. The operative term is nullity of marriage — or nullity of domestic partnership — and the governing statutes are Cal. Fam. Code §§ 2200–2210.

A nullity judgment is a court's declaration that the marriage was never legally valid. That is fundamentally different from a divorce, which terminates a marriage that did exist. The distinction matters because it affects what property rights arise, whether spousal support is available, and what the parties have to prove.

California law divides invalid marriages into two categories. Void marriages were never valid at all — no court action is required to establish their invalidity, though parties typically seek a judgment for clarity. Voidable marriages are legally valid until a court declares otherwise; they require a court proceeding, and only specific parties can bring the action.

Void marriages under Cal. Fam. Code § 2200 include marriages between parents and children, ancestors and descendants, siblings, half-siblings, uncles and nieces, and aunts and nephews. Cal. Fam. Code § 2201 makes bigamous marriages — where a prior spouse was still living and the prior marriage remained valid — void as well. Because these marriages were never legally valid, either party (or certain third parties) can challenge them at any time; there is no statute of limitations.

Voidable marriages, governed by Cal. Fam. Code §§ 2210–2212, are a different matter. They stand as valid marriages until a court acts. The six grounds — age, prior existing marriage, unsound mind, fraud, force, and physical incapacity — are discussed in detail in the next section.

One more distinction worth naming here: a *legal separation* also does not end a marriage. It resolves property and support issues while leaving the parties legally married. That is a third path, separate from both divorce and nullity. {{internal_link: legal-separation-vs-divorce-california}}

How Divorce Works Under California Law

Divorce — called dissolution of marriage in the California statutes — is available to any married couple, regardless of how long they were married, why the marriage ended, or what either party did during it. That accessibility is by design.

California is a no-fault divorce state. Under Cal. Fam. Code § 2310, irreconcilable differences is the standard ground. A petitioner does not need to prove fault, misconduct, or any particular reason for the breakdown of the marriage. The marriage simply needs to have broken down irretrievably.

There are residency requirements. Under Cal. Fam. Code § 2320, at least one spouse must have lived in California for six months and in the county where the petition is filed for three months immediately before filing. For a San Diego divorce, that means three months of San Diego County residency before the petition goes in.

Once the petition is filed and served, a mandatory waiting period applies. Cal. Fam. Code § 2339 provides that a divorce cannot be finalized until six months have passed from the date of service on the respondent or the respondent's first appearance in the case, whichever comes first. The parties can reach full agreement before that date — but the judgment cannot be entered until the waiting period expires.

California is a community property state. Under Cal. Fam. Code § 760, assets and debts acquired during the marriage are generally presumed to belong equally to both spouses. A divorce proceeding gives the court authority to divide that property, address spousal support, establish child custody and visitation arrangements, and set child support. {{internal_link: community-property-division-california}}

The Grounds for Annulment — and Why They Are Narrow

The six voidable grounds under Cal. Fam. Code § 2210 are specific and limited. Reading through them, it becomes clear why most marriages — even troubled, short, or regretted ones — do not qualify.

Age. Either party was under 18 at the time of marriage without the required parental or court consent. Only the underage party, or their parent or guardian, may bring this action. Cal. Fam. Code § 2210(a).

Prior existing marriage. A prior spouse was living and the prior marriage was still valid at the time of the second marriage. Cal. Fam. Code § 2210(b). The putative spouse doctrine under Cal. Fam. Code § 2251 may protect a good-faith spouse in this situation — more on that in the property section below.

Unsound mind. Either party lacked the mental capacity to understand the nature of the marriage at the time it was entered. Cal. Fam. Code § 2210(c).

Fraud. Consent was obtained by fraud. Cal. Fam. Code § 2210(d). California courts apply a narrow definition here: the fraud must go to the essentials of the marriage relation. Courts have recognized concealment of an inability or unwillingness to have children, and concealment of a prior existing marriage, as qualifying fraud. General deception, financial misrepresentation, or lying about personal qualities typically does not meet this standard.

Force. Consent was obtained by force. Cal. Fam. Code § 2210(e).

Physical incapacity. Either party was physically incapable of entering into the marriage state, and that incapacity appears to be incurable. Cal. Fam. Code § 2210(f).

Statutes of limitations apply to each voidable ground under Cal. Fam. Code § 2211. For fraud, force, unsound mind, and physical incapacity, the action must be brought within four years of the marriage. For age, the action must be brought before the underage party turns 22. Missing the applicable deadline means the voidable ground is no longer available, even if it genuinely existed — and the marriage must then be ended by divorce.

Void marriages under §§ 2200–2201 carry no statute of limitations. They can be challenged at any time by either party or, in some circumstances, by third parties with a legal interest.

Key Legal Differences: Property, Support, and Children

For someone weighing which path to take, the downstream consequences may matter more than the legal definitions. This is where the nullity-versus-divorce distinction becomes concrete.

Property. Because a nullity treats the marriage as never having existed, the community property framework under Cal. Fam. Code § 760 does not automatically apply. There was no community — at least in theory. In practice, the putative spouse doctrine under Cal. Fam. Code § 2251 fills part of that gap. A spouse who entered the marriage in good faith — genuinely believing it was valid — may be entitled to quasi-marital property rights that function similarly to community property. A spouse who knew the marriage was invalid from the start does not receive that protection. {{internal_link: putative-spouse-doctrine-california}}

Spousal support. In a divorce, the court has broad authority to award spousal support. In a nullity proceeding, support is generally not available — Cal. Fam. Code § 2254 limits support in nullity cases to situations where the putative spouse doctrine applies. This is one reason some parties who technically have a valid nullity ground still choose to proceed by divorce: the support protections that come with dissolution may matter more than the symbolic effect of a nullity judgment. {{internal_link: spousal-support-california}}

Children. A nullity judgment has no effect on the legal status of children. Cal. Fam. Code § 2251(b) expressly provides that children born of a void or voidable marriage are not rendered illegitimate. Child custody, visitation, and child support are addressed the same way in a nullity proceeding as in a divorce — the children's rights are not diminished because the marriage itself is being unwound. {{internal_link: child-custody-california}}

The practical implication: a short marriage with no shared property, no children, and a clear statutory ground may be a genuine candidate for nullity. A longer marriage with shared assets, retirement accounts, or a spouse who may need support almost always proceeds as a divorce — even when a nullity ground technically exists.

Name restoration is available in both proceedings.

The Process: How Each Proceeding Moves Through a San Diego Court

Both divorce and nullity petitions are filed in the San Diego Superior Court, Family Law Division. The main courthouse is located at 1555 Sixth Avenue, San Diego, CA 92101. Family law matters are also handled at the East County Regional Center at 250 E. Main Street in El Cajon and the North County Regional Center at 325 S. Melrose Drive in Vista.

The starting form is the same for both proceedings: FL-100 (Petition — Marriage/Domestic Partnership). The petitioner checks the appropriate box to indicate whether the action is for dissolution or nullity. The FL-110 summons is served on the respondent; automatic temporary restraining orders, known as ATROs, take effect the moment the petition is filed. The respondent then has 30 days to file a response using form FL-120. Judicial Council forms and filing instructions for self-represented litigants are available at selfhelp.courts.ca.gov.

From there, the two proceedings diverge.

In a divorce, if the case is uncontested, it can proceed by default or stipulated judgment once the six-month waiting period under Cal. Fam. Code § 2339 has run. No trial is required. Many San Diego divorces where the parties agree on all terms are resolved without a court hearing beyond the initial filing.

In a nullity, there is no six-month waiting period — the court can grant nullity as soon as the ground is proven. But the petitioner bears the burden of proof and must establish the specific statutory ground at a hearing or trial. A contested nullity proceeding can take considerably longer than an uncontested divorce, precisely because the evidentiary showing is required.

Filing fees for both petition types are set by statute under Gov. Code § 70670. Current fee amounts are published at sdcourt.ca.gov and are subject to change; the court's website is the reliable source for current figures.

Common Misconceptions About Annulment in California

A few persistent myths about annulment circulate widely — and believing them can lead someone to pursue the wrong proceeding, or to expect an outcome the law does not provide.

"We were only married a few months, so we qualify for an annulment." Duration of marriage is not a ground for nullity under California law. A marriage of three months and a marriage of three years are treated identically: if no statutory ground under Cal. Fam. Code §§ 2200–2210 exists, the marriage must be ended by divorce. The length of the marriage is simply not relevant to nullity eligibility.

"A religious annulment means I can get a legal annulment." A religious annulment — such as one granted by the Catholic Church — has no legal effect in California. Civil and religious proceedings are entirely separate systems. A person who has received a religious annulment still has a legally existing marriage until a California court enters a civil judgment of dissolution or nullity.

"Annulment is faster and cheaper than divorce." This one depends entirely on the facts. A contested nullity proceeding requires proving a ground at hearing or trial, which can be more time-consuming and costly than an uncontested divorce. For a marriage with no qualifying ground, an uncontested dissolution is typically the more straightforward path.

"Annulment means my children are illegitimate." This is false. Cal. Fam. Code § 2251(b) expressly protects the status of children born of void or voidable marriages. The nullity of the marriage has no effect on the children's legal standing.

"I can get spousal support after an annulment." Generally, no. Support is not available in a nullity proceeding unless the putative spouse doctrine applies under Cal. Fam. Code §§ 2251–2254. Parties who anticipate a support need — or who may owe support — should factor this into the decision about which proceeding to pursue.

Which Path Fits Which Situation

Nullity is the legally appropriate vehicle when a specific statutory ground under Cal. Fam. Code §§ 2200–2210 exists and the applicable statute of limitations has not run. Both conditions must be met. A ground that existed but whose limitations period has expired is no longer available.

Divorce is available to any married couple, regardless of grounds, duration, or circumstances. It is the default path when no nullity ground applies — and it remains available even when a nullity ground does exist, if the parties prefer its property and support framework.

Situations where nullity is commonly sought include marriages entered under fraud going to the essentials of the marriage relation, marriages where one party genuinely lacked mental capacity at the time of the ceremony, and bigamous marriages discovered after the fact.

Situations where divorce is the appropriate path even if a party wishes otherwise include marriages where the only complaint is that it was short, that the parties grew apart, or that one party behaved badly. Conduct — even serious misconduct — is not a ground for nullity under California law.

It is also worth noting that even when a nullity ground technically exists, some parties choose dissolution because of the property and support protections it provides. The putative spouse doctrine has real limits, and a spouse who entered the marriage in bad faith receives no quasi-marital property rights at all. A California family law attorney can evaluate whether a specific set of facts supports a nullity ground and what the downstream consequences of each path would look like in that particular case.

Frequently asked questions

Can I get an annulment in California just because we were only married for a short time?

No. Duration of marriage is not a ground for nullity under California law. A short marriage that does not meet one of the statutory grounds in Cal. Fam. Code §§ 2200–2210 must be ended by divorce, regardless of how brief the marriage was.

What is the difference between a void marriage and a voidable marriage in California?

A void marriage — such as an incestuous or bigamous marriage under Cal. Fam. Code §§ 2200–2201 — was never legally valid and can be challenged at any time by either party or certain third parties, with no statute of limitations. A voidable marriage under Cal. Fam. Code §§ 2210–2211 is legally valid until a court declares it invalid; only specific parties may bring the action, and time limits apply to each ground.

Does a religious annulment count as a legal annulment in California?

No. A religious annulment, such as one granted by the Catholic Church, has no legal effect in California. Civil and religious proceedings are entirely separate. A person who has obtained a religious annulment still needs a civil divorce or nullity judgment from a California court to end the legal marriage.

What happens to property and assets if a California court grants a nullity?

Because a nullity treats the marriage as never having existed, standard community property rules do not automatically apply. However, a spouse who entered the marriage in good faith may have rights under the putative spouse doctrine under Cal. Fam. Code § 2251, which can provide quasi-marital property rights similar to community property. A spouse who knew the marriage was invalid does not receive that protection.

Can I get spousal support after an annulment in California?

Generally no. Spousal support is not available in a nullity proceeding unless the putative spouse doctrine applies under Cal. Fam. Code §§ 2251–2254. This is one reason some parties who have a technically valid nullity ground still choose to proceed by divorce — the support framework that comes with dissolution may matter more than the nullity declaration itself.

What are the residency requirements to file for divorce in California?

Under Cal. Fam. Code § 2320, at least one spouse must have lived in California for six months and in the county where the petition is filed for three months immediately before filing. For a San Diego divorce, that means three months of San Diego County residency before the petition is filed. Nullity proceedings do not carry the same residency requirement, though the petitioner must still file in a court with proper jurisdiction.

How long does an annulment take compared to a divorce in California?

Divorce carries a mandatory six-month waiting period from service or appearance before it can be finalized under Cal. Fam. Code § 2339; nullity has no waiting period. That said, nullity requires proving a ground at a hearing or trial, which can make a contested nullity proceeding longer and more involved than an uncontested divorce where the parties agree on all terms.

Are children born of a marriage that is later annulled considered illegitimate in California?

No. Cal. Fam. Code § 2251(b) expressly provides that children born of a void or voidable marriage are not rendered illegitimate. Child custody, visitation, and support are handled the same way regardless of whether the parents divorce or obtain a nullity — the children's legal status is not affected by the nullity judgment.

What is fraud as a ground for annulment in California — and what doesn't qualify?

California courts apply a narrow definition under Cal. Fam. Code § 2210(d): the fraud must go to the "essentials of the marriage relation." Courts have recognized concealment of an inability or unwillingness to have children, and concealment of a prior existing marriage, as qualifying. General deception, financial fraud, or misrepresentation about personal qualities typically does not meet the standard — which is why fraud claims in nullity proceedings are often harder to establish than people expect.

If You'd Like to Talk Through Your Situation

The question of whether a marriage qualifies for nullity — or whether dissolution is the more appropriate path given the property and support stakes — turns on specific facts that a general article cannot resolve. In a consultation, an attorney will ask about the circumstances of the marriage, the ground being considered, when the parties separated, what property or support issues are in play, and whether the applicable statute of limitations is still open. Those facts determine which proceeding is available and what the practical consequences of each path would be in that particular case.

For readers who are still in the early stages of figuring out whether they need legal help at all, a conversation focused on those threshold questions — does a ground exist, and does it still matter given the facts — is often the most useful starting point.
