California offers two distinct legal pathways to end a marriage: annulment (nullity) and divorce (dissolution). An annulment under Cal. Fam. Code § 2200-2210 declares a marriage legally invalid from its beginning, while a divorce under Cal. Fam. Code § 2310 terminates a valid marriage. The filing fee for both proceedings is $435 as of 2026, but annulment requires proving specific statutory grounds such as fraud, bigamy, or incest, whereas divorce only requires stating irreconcilable differences. California courts granted approximately 135,000 divorces in 2024 compared to fewer than 5,000 annulments, reflecting the higher evidentiary burden for nullity cases.
Key Facts: Annulment vs. Divorce in California
| Factor | Annulment | Divorce |
|---|---|---|
| Filing Fee | $435 | $435 |
| Residency Requirement | California resident at filing | 6 months state + 3 months county |
| Waiting Period | None | 6 months minimum |
| Grounds Required | Void or voidable marriage | Irreconcilable differences |
| Property Division | Only with putative spouse status | Community property 50/50 |
| Spousal Support | Only with putative spouse status | Available based on circumstances |
| Legal Effect | Marriage never existed | Marriage terminated |
| Burden of Proof | Clear and convincing evidence | Preponderance of evidence |
What Is the Difference Between Annulment and Divorce in California?
Annulment in California declares that a valid marriage never legally existed, treating the union as void from its inception under Cal. Fam. Code § 2200. Divorce, by contrast, acknowledges a valid marriage occurred and legally terminates it going forward. This distinction carries significant legal consequences: annulment erases the marriage from legal records, while divorce creates a documented marital history. California processes approximately 27 times more divorces than annulments annually, reflecting the stringent proof requirements for nullity.
The legal effects extend beyond paperwork. In divorce proceedings, California courts automatically divide community property equally under Cal. Fam. Code § 760, award spousal support based on statutory factors, and distribute marital debts. In annulment cases, courts can only divide property and order support if at least one spouse qualifies as a putative spouse under Cal. Fam. Code § 2251, meaning they believed in good faith the marriage was valid.
Marriage length does not determine eligibility for annulment. A couple married for one day must still prove specific legal grounds, while a couple married for 30 years may qualify if fraud is discovered. The common misconception that short marriages automatically qualify for annulment has no basis in California law. Courts evaluate statutory criteria, not duration.
Grounds for Annulment in California: Void vs. Voidable Marriages
California recognizes two categories of invalid marriages: void marriages that are legally invalid from the start under Cal. Fam. Code § 2200-2201, and voidable marriages that remain valid until a court declares them void under Cal. Fam. Code § 2210. The distinction affects both timing and available remedies. Void marriages can be challenged at any time by either spouse, their heirs, or even third parties with legal standing. Voidable marriages must be challenged by the affected spouse within specific statutory timeframes.
Void Marriages Under California Law
Void marriages are considered legally invalid from the moment of the ceremony under California Family Code sections 2200 and 2201. No court action is technically required to establish their invalidity, though obtaining a formal judgment provides legal clarity. California recognizes two grounds for void marriages:
Incestuous marriages between close blood relatives are void under Cal. Fam. Code § 2200. This includes marriages between parents and children, grandparents and grandchildren, siblings (full or half-blood), and aunts or uncles with nieces or nephews. The prohibition applies regardless of whether the relationship is biological or through adoption, legitimate or illegitimate.
Bigamous marriages where one spouse was already legally married to another living person are void under Cal. Fam. Code § 2201. If a prior marriage was dissolved or the former spouse died before the current marriage, bigamy does not apply. California does not recognize common law marriage, so informal prior relationships do not create bigamy issues.
Voidable Marriages Under California Law
Voidable marriages under Cal. Fam. Code § 2210 are legally valid until a court issues an annulment judgment. California recognizes six grounds for voidable marriages, each with specific statutory timeframes for filing:
| Ground | Description | Filing Deadline |
|---|---|---|
| Age | Either spouse under 18 without parental/court consent | 4 years after turning 18 |
| Prior Existing Marriage | Spouse believed former spouse was dead | Before death of either party |
| Unsound Mind | Lacked mental capacity to consent | Any time before death |
| Fraud | Consent obtained through material deception | 4 years after discovering fraud |
| Force | Marriage entered under duress or coercion | 4 years after marriage |
| Physical Incapacity | Incurable inability to consummate | 4 years after marriage |
Fraud must be substantial and directly related to the marriage relationship under California case law. Examples include concealing the inability or unwillingness to have children, hiding a significant incurable disease, or marrying solely to obtain immigration benefits. Ordinary lies about finances, career, or personal history typically do not qualify unless they affect the fundamental purpose of the marriage.
California Divorce Requirements: What You Need to Know
California divorce requires meeting specific residency and procedural requirements before a court can enter a final judgment of dissolution. The state operates as a no-fault jurisdiction, meaning neither spouse must prove wrongdoing to obtain a divorce. Courts do not consider evidence of adultery, abandonment, or other marital misconduct when granting dissolution, though such evidence may be relevant to child custody or spousal support in limited circumstances.
Residency Requirements for California Divorce
Cal. Fam. Code § 2320 mandates that at least one spouse must have been a California resident for 6 months and a resident of the filing county for 3 months immediately before filing. Military personnel stationed in California satisfy the residency requirement. Couples who do not meet these requirements can file for legal separation immediately, which allows courts to address property division, support, and custody while waiting to convert the case to dissolution.
Same-sex couples married in California but residing in states that will not dissolve their marriage may file for dissolution in the California county where they married, regardless of current residency under Cal. Fam. Code § 2320(b).
California's 6-Month Waiting Period
California imposes a mandatory 6-month cooling-off period under Cal. Fam. Code § 2339 from the date the responding spouse is served with divorce papers. The earliest a California divorce can become final is 6 months and 1 day after service. This waiting period cannot be waived, shortened, or avoided, even if both spouses agree to all terms. Parties can negotiate their settlement, complete required disclosures, and finalize their agreement during this period, but the court cannot enter judgment until the waiting period expires.
Grounds for Divorce in California
California recognizes only two grounds for divorce under Cal. Fam. Code § 2310: irreconcilable differences and incurable insanity. Approximately 99% of California divorces cite irreconcilable differences, which requires only a statement that the marriage has irretrievably broken down. Incurable insanity requires proof by medical testimony that the condition existed at the time of filing and remains incurable, making it rarely used.
Filing Fees and Costs: Annulment vs. Divorce in California
The court filing fee for both annulment and divorce in California is $435 as of January 2026, following the Statewide Civil Fee Schedule. If the responding spouse files a formal response, an additional $435 fee applies, bringing total court costs to $870 for contested cases. Starting January 1, 2026, California's new Joint Petition for Dissolution (Form FL-700) allows agreeing couples to file together for a single $435 fee instead of $870, provided both parties agree to all final terms in writing.
Fee Waiver Eligibility
California offers fee waivers for qualifying individuals under Judicial Council Form FW-001. You may qualify if your household income is at or below 125% of the federal poverty guidelines (approximately $19,688 for a single person in 2026), you receive public benefits such as CalWORKs, Medi-Cal, Food Stamps/CalFresh, or SSI, or you cannot afford basic living expenses and court fees.
Total Cost Comparison
| Cost Category | Annulment | Uncontested Divorce | Contested Divorce |
|---|---|---|---|
| Court Filing Fee | $435 | $435-$870 | $435-$870 |
| Process Server | $50-$200 | $50-$200 | $50-$200 |
| Attorney Fees | $3,000-$15,000+ | $700-$6,000 | $15,000-$30,000+ |
| Expert Witnesses | $1,000-$5,000+ | Rare | $2,000-$10,000+ |
| Total Range | $4,500-$20,000+ | $435-$6,500 | $17,500-$100,000+ |
Annulment cases typically cost more than uncontested divorces because proving statutory grounds requires evidence beyond simple agreement. Fraud cases may require expert testimony on psychological harm. Physical incapacity cases require medical evidence. Contested annulments can approach or exceed the cost of contested divorces.
Property Division: How Annulment and Divorce Differ
California is one of nine community property states, meaning all property acquired during marriage while domiciled in California is presumed jointly owned under Cal. Fam. Code § 760. In divorce, courts divide community property equally (50/50) between spouses, regardless of who earned the income or whose name appears on titles. Separate property, including assets owned before marriage, gifts, and inheritances under Cal. Fam. Code § 770, remains with the owning spouse.
Annulment proceedings operate differently. Because annulment declares the marriage legally invalid from its inception, standard community property rules do not automatically apply. Courts can only divide property and debts if at least one spouse qualifies as a putative spouse under Cal. Fam. Code § 2251. Without putative spouse status, each party keeps the assets in their name, regardless of when they were acquired.
The Putative Spouse Doctrine
A putative spouse is someone who believed in good faith that their marriage was legally valid under California law. The good faith standard is subjective, focusing on what the individual actually believed rather than what a reasonable person would believe. Courts consider factors such as whether the party knew or should have known about the defect, received advice about the marriage's validity, or participated in conduct that caused the invalidity.
If a court declares one or both spouses putative, property acquired during the invalid marriage that would have been community property becomes quasi-marital property under Cal. Fam. Code § 2251(a). Courts divide quasi-marital property equally between putative spouses, mirroring divorce procedures. The party who caused the marriage to be invalid, such as through fraud or bigamy, cannot claim putative spouse status and cannot receive quasi-marital property or spousal support.
Spousal Support in Annulment vs. Divorce Cases
California courts can award spousal support in divorce cases based on factors including marriage length, each spouse's earning capacity, the marital standard of living, and contributions to the other spouse's education or career under Cal. Fam. Code § 4320. For marriages over 10 years, the court retains jurisdiction to modify support indefinitely. For shorter marriages, support typically lasts half the marriage length.
In annulment cases, spousal support is only available to a putative spouse under Cal. Fam. Code § 2254. If neither spouse qualifies as putative, the court cannot order support regardless of financial circumstances. The guilty party, such as the spouse who committed fraud, cannot receive spousal support from the innocent spouse even if they would otherwise qualify based on need.
Children and Annulment: Legal Protections
Children born during an annulled marriage remain legitimate under California law. Annulment does not affect paternity, child custody, child support, or parenting time arrangements. Courts make these determinations based on the child's best interests under Cal. Fam. Code § 3011, regardless of whether the parents' marriage is dissolved by divorce or declared void by annulment.
Both parents remain legally responsible for child support under California's child support guidelines regardless of marital status. The non-custodial parent's support obligation is calculated using the same formula whether the marriage ended by divorce or annulment. Custody and visitation orders protect children's relationships with both parents without regard to how the marriage ended.
How to Decide: Annulment or Divorce?
Choosing between annulment and divorce depends on whether you have legal grounds for annulment and whether the benefits outweigh the additional complexity and cost. Most people seeking annulment cannot meet the statutory requirements and must proceed with divorce instead. Consider annulment if:
You can prove a specific ground under California Family Code sections 2200-2210 with clear and convincing evidence. You discovered fraud, force, or incapacity within the applicable statute of limitations. You want the legal record to show the marriage was never valid. Religious or personal beliefs make annulment preferable to divorce.
Consider divorce if: You cannot prove annulment grounds or are outside the filing deadline. You need the certainty of community property division and spousal support rights. You want to minimize legal costs and complexity. Both spouses agree to divorce terms and can use California's new Joint Petition option.
Step-by-Step Process: Filing for Annulment in California
- Verify California residency (no minimum period required for annulment)
- Identify your legal ground under Cal. Fam. Code § 2200-2210
- Gather evidence supporting your annulment ground
- Complete Petition for Nullity of Marriage (Form FL-100) and Summons (Form FL-110)
- Pay $435 filing fee or submit fee waiver request (Form FW-001)
- Serve your spouse through a third party or process server
- Wait 30 days for your spouse's response
- Attend court hearing to present evidence of annulment grounds
- Receive judgment of nullity if grounds are proven
Unlike divorce, annulment has no mandatory 6-month waiting period. If your spouse does not contest the annulment and you can prove your grounds, the case may resolve in 60-90 days. Contested annulments requiring trial may take 12-18 months or longer.
Frequently Asked Questions About Annulment vs. Divorce in California
How long do you have to be married to get an annulment in California?
California has no marriage length requirement for annulment. You can seek annulment after one day or 30 years if you can prove statutory grounds under Cal. Fam. Code § 2200-2210. However, specific grounds have filing deadlines: fraud requires filing within 4 years of discovery, force requires filing within 4 years of marriage, and physical incapacity requires filing within 4 years of marriage.
Can I get an annulment if my spouse cheated?
No, adultery is not grounds for annulment in California. Infidelity after marriage does not make the marriage void or voidable because the marriage was validly entered. However, if your spouse fraudulently concealed a pre-existing extramarital relationship or intent to continue that relationship, this might qualify as fraud affecting the essence of the marriage relationship.
What happens to property if I get an annulment instead of a divorce?
In annulment, courts can only divide property if you qualify as a putative spouse under Cal. Fam. Code § 2251, meaning you believed in good faith the marriage was valid. Without putative spouse status, each party keeps assets in their name. In divorce, community property is automatically divided 50/50 under Cal. Fam. Code § 760.
How much does an annulment cost in California compared to divorce?
Both annulment and divorce have a $435 filing fee as of 2026. However, annulments typically cost more overall because proving statutory grounds requires evidence and often expert witnesses. Uncontested divorces range from $435-$6,000, while annulment cases average $4,500-$20,000+ depending on complexity and whether the case is contested.
Can I get spousal support after an annulment?
Spousal support after annulment is only available if you qualify as a putative spouse who believed in good faith the marriage was valid under Cal. Fam. Code § 2254. The party who caused the invalidity, such as through fraud or bigamy, cannot receive support from the innocent spouse regardless of financial need.
Does an annulment affect child custody or support?
No, annulment does not affect child custody, child support, or paternity determinations. Children born during an annulled marriage remain legitimate under California law. Courts make custody and support decisions based on the child's best interests under Cal. Fam. Code § 3011, applying the same standards whether the parents' marriage ended by divorce or annulment.
How long does an annulment take compared to divorce in California?
Annulment has no mandatory waiting period and can finalize in 60-90 days for uncontested cases. Divorce requires a minimum 6-month waiting period under Cal. Fam. Code § 2339 from service date. However, contested annulments requiring trial may take 12-18 months, while uncontested divorces finalize at the 6-month mark.
Can I get an annulment if I was drunk when I got married?
Possibly, if intoxication rose to the level of unsound mind under Cal. Fam. Code § 2210(a). You must prove you were so intoxicated you could not understand the nature and duties of marriage at the time of the ceremony. Mere impairment is insufficient; you must show complete inability to consent. Continuing to live as spouses after becoming sober may waive this ground.
What is the deadline to file for annulment in California?
Deadlines vary by ground: fraud and force require filing within 4 years (from discovery of fraud or from marriage for force), physical incapacity requires filing within 4 years of marriage, underage marriage requires filing within 4 years of turning 18, and unsound mind has no deadline. Void marriages (incest, bigamy) can be challenged at any time.
Is an annulment or divorce better for my situation?
Divorce is typically the better choice unless you have clear evidence of annulment grounds and a strong reason to void the marriage rather than dissolve it. Annulment requires a higher burden of proof (clear and convincing evidence vs. preponderance), costs more due to evidentiary requirements, and may not provide property division or spousal support rights if you cannot establish putative spouse status.
Conclusion
California's legal framework provides distinct pathways for ending a marriage through annulment or divorce. Annulment under Cal. Fam. Code § 2200-2210 declares a marriage legally void but requires proving specific statutory grounds with clear and convincing evidence. Divorce under Cal. Fam. Code § 2310 terminates a valid marriage based on irreconcilable differences without requiring proof of fault. Both proceedings begin with a $435 filing fee as of 2026, but annulment typically costs more due to evidentiary requirements and the potential need for expert witnesses.
The choice between annulment and divorce affects property rights, spousal support eligibility, and the legal status of the marriage. Understanding these differences helps you select the appropriate legal pathway for your circumstances. Consulting with a California family law attorney can clarify which option best serves your interests based on your specific situation.
