How To Get An Annulment In California: Step-by-Step Legal Guide

To obtain an annulment (legally termed a "nullity of marriage") in California, you must file a Petition (Form FL-100) in the Superior Court establishing a statutory ground under California Family Code Sections 2200 or 2210, such as fraud, force, or physical incapacity. Unlike a divorce, which requires six months of residency, an annulment can be filed immediately if either party resides in the state or if the marriage was performed in California. You must present corroborating evidence at a mandatory court hearing to secure a judgment of nullity, as California courts do not grant annulments by default paperwork alone.

Pre-Filing Requirements and Legal Grounds in California

Before initiating the filing process, you must determine whether your marriage qualifies for a nullity. Under California law, marriages are categorized as either void (automatically illegal and invalid from inception) or voidable (valid until a judge declares them null).

Unlike a dissolution of marriage (divorce), which only requires a claim of "irreconcilable differences," an annulment requires you to meet strict burden-of-proof standards. Furthermore, while a California divorce requires at least one spouse to have resided in the state for six months and the county for three months, there is no durational residency requirement for an annulment. You must only establish that either spouse is a resident of California at the time of filing, or that the marriage was solemnized within the state of California.

Preparation Checklist and Resource Allocation

• Mandatory Judicial Council Forms: Form FL-100 (Petition), Form FL-110 (Summons), and Form FL-115 (Proof of Service of Summons).
• Supportive Declarations: Form MC-030 (Declaration) or a customized attachment detailing the facts that support your specific legal grounds for nullity.
• Certified Marriage Certificate: Obtained from the Registrar-Recorder/County Clerk in the county where the marriage license was issued.
• Filing Fee Budget: $435 to $450 (varies slightly by county) or an approved Fee Waiver application (Forms FW-001 and FW-003).
• Process Server: A neutral third party over the age of 18, or a registered process server, to execute personal service of process.
• Duration Benchmark: 3 to 12 months, depending on court docket congestion and whether the respondent contests the nullity.

Step-by-Step California Nullity of Marriage Procedure

Step 1: Identify and Document Your Specific Statutory Grounds

You cannot obtain an annulment simply because the marriage was brief. You must fit your case into one of the explicit statutory grounds recognized under California law.

• Incest (Family Code Section 2200): The spouses are ancestors/descendants, siblings, half-siblings, uncles/nieces, or aunts/nephews.
• Bigamy (Family Code Section 2201): One spouse was already legally married to or in a domestic partnership with another living person.
• Underage (Family Code Section 2210(a)): The petitioner was under 18 years of age at the time of the marriage and lacked parental consent or a court order.
• Prior Existing Marriage (Family Code Section 2210(b)): A spouse was married, but the former spouse was absent and believed dead for five consecutive years preceding the subsequent marriage.
• Unsound Mind (Family Code Section 2210(c)): Either party lacked the cognitive capacity to consent to the marriage contract due to mental illness, severe intoxication, or cognitive decline.
• Fraud (Family Code Section 2210(d)): One party consented to the marriage based on a vital misrepresentation that "goes to the heart of the marriage." Examples include marrying solely for immigration benefits, hiding infertility while promising to have children, or concealing a criminal record of child abuse.
• Force (Family Code Section 2210(e)): Consent to marry was obtained via threats of physical harm or duress.
• Physical Incapacity (Family Code Section 2210(f)): One party is physically incapable of entering into the marriage state (specifically, the permanent inability to engage in natural sexual intercourse), and the incapacity continues and appears incurable.

Warning: If you continue to freely cohabit (live together as spouses) after discovering the fraud, recovering your sanity, or reaching the age of majority, you waive your right to an annulment on those grounds. The court will treat subsequent filings as dissolutions of marriage.

Step 2: Draft the Mandatory Judicial Council Petition Packets

To initiate the action, you must fill out several specific legal forms using blue or black ink, or a PDF editor.

1. Form FL-100 (Petition - Marriage/Domestic Partnership): Check the box for "Nullity of Marriage" in the caption. In Section 2, specify the residency status. In Section 8, check the box corresponding to your specific statutory ground under Family Code 2200 or 2210.
2. Form FL-110 (Summons): This form warns your spouse that a lawsuit has been filed and that they have 30 calendar days to respond. It also outlines automatic temporary restraining orders (ATROs) restricting the transfer of property or child relocation.
3. Form FL-105 (Declaration Under Uniform Child Custody Jurisdiction and Enforcement Act): Mandatory only if you and your spouse have minor children together. This form tracks the children’s residences for the past five years.
4. Local County Forms: Check your local Superior Court’s website (such as Los Angeles Superior Court Form FAM 015 or similar regional documents) for mandatory local family law cover sheets.

Step 3: File the Petitions at the Local Family Court Clerk’s Office

Take your completed forms to the Family Law Clerk's office in the county where either you or your spouse resides.

1. Create three complete physical copies of the entire packet: the original for the court, one copy for your records, and one copy to serve on your spouse.
2. Submit the packet to the clerk. You must pay the filing fee of approximately $435, or present the Fee Waiver forms (FW-001 and FW-003) if you meet the low-income criteria.
3. The clerk will stamp your forms "Filed," assign a unique family law case number, and return the two copy packets with conforming court seals.

Step 4: Execute Service of Process

You cannot hand or mail the filed documents to your spouse yourself. Service must be executed in accordance with California Code of Civil Procedure Section 415.10.

1. Hire a professional process server, a county sheriff, or ask a friend or relative who is at least 18 years old and not a party to the case to deliver the documents.
2. The server must hand-deliver a copy of all filed forms, along with a blank Response (Form FL-120), to your spouse (the respondent).
3. Once served, the process server must complete Form FL-115 (Proof of Service of Summons), detailing the date, time, and precise address of service.
4. File the original Form FL-115 with the court clerk. This starts the statutory 30-day response clock.

Step 5: Schedule and Prepare for the Evidentiary Hearing

California courts do not sign off on an annulment based purely on the pleadings. You must prove your grounds to a family law judge.

1. If your spouse does not file a Response (Form FL-120) within 30 days, you must file Form FL-165 (Request to Enter Default).
2. Request a hearing date for your Nullity of Marriage. This is done by filing a local court Request for Informal Trial or scheduling a formal evidentiary hearing using Form FL-300 (Request for Order).
3. Gather physical evidence to support your claims. For bigamy, bring a certified copy of the spouse’s prior, undissolved marriage certificate. For fraud, present written communications, text messages, or witness affidavits proving the deception.
4. On your court date, present your testimony and evidence clearly. If the judge is satisfied that the evidentiary burden has been met, they will sign Form FL-190 (Notice of Entry of Judgment) and Form FL-180 (Judgment).

Pro-Tip: If you have shared assets or minor children, request the court to declare you a "Putative Spouse" under Family Code Section 2251. If the judge finds that you believed in good faith that the marriage was valid, they can divide "quasi-marital property" and award spousal support, protections that are otherwise unavailable in a standard annulment.

Technical Comparison of Annulment Grounds, Statutes of Limitations, and Evidentiary Proof

The legal mechanics of proving a void or voidable marriage vary drastically depending on the specific ground selected on your FL-100 Petition.

Common Filing Failures and Courtroom Remedies

Scenario 1: Petition Rejected Due to Expired Statute of Limitations

• Root Cause: The petitioner filed for an annulment based on fraud five years after discovering that their spouse married them solely to obtain a green card.
• Actionable Fix: Since the four-year statutory window under Family Code Section 2210(d) has closed, the annulment is legally barred. The petitioner must amend Form FL-100 to request a "Dissolution of Marriage" (divorce) based on irreconcilable differences.

Scenario 2: Court Denies Nullity Due to Voluntary Cohabitation

• Root Cause: The petitioner discovered their spouse was physically incapable of consummating the marriage, yet they lived together in the same residence for two years after this discovery before filing for an annulment.
• Actionable Fix: The respondent's attorney will argue that voluntary cohabitation occurred after the impediment was discovered. To overcome this, the petitioner must present clear evidence of immediate, separate living arrangements or separate bedrooms, proving a total cessation of the marital relationship upon discovering the incapacity.

Scenario 3: Clerical Rejection of Proof of Service (Form FL-115)

• Root Cause: The petitioner mailed the initial Summons and Petition directly to the respondent via standard first-class mail, or personally handed the documents to the respondent.
• Actionable Fix: A party to the action cannot serve the papers. The petitioner must have a non-party adult (such as a professional process server) personally hand the documents to the respondent. Alternatively, they can use Notice and Acknowledgment of Receipt (Form FL-117) if the respondent is willing to sign and return it to acknowledge service by mail.

Frequently Asked Questions

Can I get an annulment in California if I was married in another state?

Yes. You can obtain an annulment in California even if your marriage took place in another state or country. However, you or your spouse must be a current resident of California at the time you file the petition, and you must satisfy the court with clear evidence supporting one of the statutory grounds under California Family Code Section 2210.

How long does it take to get an annulment in California?

An annulment does not have the mandatory six-month waiting period required for a divorce. However, the timeline depends entirely on court availability, service of process, and whether your spouse contests the filing. A simple, uncontested annulment with a cooperative spouse typically takes between three and six months to finalize.

What happens to our property and children if the marriage is annulled?

If a marriage is annulled, it legally never existed. Consequently, standard community property laws do not automatically apply. To protect your rights to shared assets or support, you must ask the judge to declare you a "putative spouse" under Family Code Section 2251, proving you entered the marriage with a good-faith belief that it was valid. Child custody, visitation, and child support are handled normally, but parentage must first be established through the court.

Do I have to go to court to get an annulment in California?

Yes. Unlike a standard dissolution of marriage, which can often be finalized entirely through paperwork, a nullity of marriage requires a live evidentiary hearing. You must appear before a family law judge to testify under oath and present physical evidence or witness testimony proving your legal grounds for the annulment.
