How to File for Divorce in California: A Step-by-Step Guide (2026)

Filing for divorce in California can feel overwhelming, but the process is more straightforward than most people think. This guide walks you through every step, from checking your eligibility to finalizing your divorce.

Before You Start: Residency Requirements

To file for divorce in California, at least one spouse must have lived in the state for 6 months and in the county where you plan to file for 3 months. If you don't meet these requirements yet, you may need to wait or file in a different county.

If you meet the residency requirement in multiple counties, you can choose where to file. Processing times vary — some smaller counties are significantly faster than large metro courts. Check our California county directory for court-specific processing information.

What if neither spouse lives in California? You cannot file for divorce in California unless at least one spouse meets the residency requirement. However, if you were married in California but live elsewhere, you file in the state where you currently reside.

Step 1: Prepare Your Petition (FL-100)

The divorce process begins with the Petition — Marriage/Domestic Partnership (FL-100). This form tells the court basic information about your marriage and what you're asking for (see our complete guide to California divorce forms for details on every form), including:

• Grounds for divorce (California is a no-fault state — you only need to cite "irreconcilable differences")
• Requests regarding property, custody, and support
• Date of marriage and date of separation

You'll also need to file the Summons (FL-110), which notifies your spouse that a divorce case has been started and puts automatic temporary restraining orders (ATROs) in effect.

If you have minor children, you'll also file FL-105 (Declaration Under UCCJEA), which tells the court about your children's living arrangements.

Important: Make sure you request everything you want in the Petition. If you don't check the box for spousal support, for example, you may not be able to add it later without your spouse's agreement.

Step 2: File with the Court

Once your petition is complete, you file it with the Superior Court in your county. The filing fee in California is $435. If you can't afford the fee, you may qualify for a fee waiver by filing form FW-001 — see our divorce cost guide for eligibility details.

Many California counties now accept electronic filing (e-filing), which means you can submit your documents online without visiting the courthouse. E-filing is faster and creates an immediate record of your submission.

Filing by County

Each county has its own Superior Court with specific procedures. Here are some of the most-filed counties:

• Los Angeles County — California's largest court system, serving 10+ million residents
• San Diego County — E-filing available through approved EFSPs
• Orange County — Family law cases handled at Lamoreaux Justice Center
• Riverside County — Family Law courthouse in downtown Riverside
• Santa Clara County — Family Court on Hedding Street in San Jose
• Sacramento County — William R. Ridgeway Family Relations Courthouse
• San Francisco County — Civic Center Courthouse
• Alameda County — Hayward Hall of Justice
• San Bernardino County — Multiple courthouse locations
• Fresno County — Sisk Federal Courthouse area

Step 3: Serve Your Spouse

After filing, your spouse must be officially notified — this is called service of process. In California, you cannot serve the papers yourself (learn more in our guide to serving divorce papers). You can:

• Have someone over 18 (not you) hand-deliver the papers
• Use a professional process server ($50–$150)
• Use a county sheriff's office
• If your spouse agrees, they can sign an Acknowledgment of Receipt (FL-117)

Your spouse has 30 days to file a response after being served.

Important timing note: The 6-month waiting period starts on the date of service, not the date of filing. Serve your spouse as soon as possible to start the clock.

Step 4: Financial Disclosures

Both spouses are required to exchange Preliminary Declarations of Disclosure, which include:

• Income and Expense Declaration (FL-150) — your income, expenses, and financial obligations
• Schedule of Assets and Debts (FL-142) — everything you own and owe
• Declaration of Disclosure (FL-140) — a cover sheet for the disclosure package

This step is required even if your divorce is uncontested. California Family Code §2104 mandates full financial transparency — you cannot skip or waive preliminary disclosures (though you can waive final disclosures by agreement).

Deadline: The petitioner must serve disclosures within 60 days of filing the Petition. The respondent must serve within 60 days of filing their Response.

After serving disclosures, each spouse files FL-141 (Declaration Regarding Service of Declaration of Disclosure) with the court to confirm they completed this step. This is the most commonly forgotten form in California divorce — and the court cannot enter your judgment without it.

Step 5: Reach an Agreement or Go to Trial

If you and your spouse agree on all terms (an uncontested divorce), you can prepare a Marital Settlement Agreement that outlines how you'll divide property, handle custody, and manage support.

Key areas your agreement must cover:

• Property division — California is a community property state; assets and debts acquired during marriage are generally split 50/50, but you can agree to a different division. See our guides on dividing the family home and dividing retirement accounts.
• Spousal support — amount, duration, and conditions. For marriages over 10 years, see our guide on the 10-year rule for alimony.
• Child custody and visitation — legal custody, physical custody, and the parenting schedule
• Child support — calculated using California's guideline formula

If you can't agree, the case may go to mediation or trial — but the vast majority of California divorces are resolved by agreement.

Step 6: File Your Judgment

Once you have an agreement, you submit your Judgment (FL-180) along with supporting documents to the court for approval. The judgment packet typically includes:

• FL-180 (Judgment)
• Marital Settlement Agreement
• Child custody and visitation order (if applicable)
• Child support order (if applicable)
• FL-141 from both spouses (confirming disclosures were served)

The judge reviews everything and, if it's in order, signs the judgment. If there are errors or inconsistencies, the court will send the packet back for corrections — this is a common source of delay.

The 6-Month Waiting Period

California has a mandatory 6-month waiting period from the date your spouse was served. Even if you resolve everything quickly, the divorce cannot be finalized until this period has passed. Learn more about how long divorce takes in California.

Strategy: Submit your judgment packet well before the 6-month mark so the court can review it. If everything is approved by the time the waiting period ends, the judge can sign your judgment immediately.

Frequently Asked Questions

How fast can I file for divorce in California?

You can file immediately if you meet the residency requirements (6 months in California, 3 months in your county). However, California has a mandatory 6-month waiting period before the divorce can be finalized, even if both spouses agree on everything.

Do both spouses need a lawyer?

No. Many couples complete an uncontested divorce without hiring lawyers. MutualFile helps you prepare all required court forms and file them electronically. If your divorce involves complex assets, custody disputes, or safety concerns, you should consult a licensed attorney.

Can the entire divorce process be done online?

In many cases, yes. If your divorce is uncontested and your county accepts e-filing, you can complete the process without visiting the courthouse. MutualFile handles the paperwork and filing online.

What if my spouse won't cooperate?

If your spouse doesn't respond within 30 days of being served, you may be able to proceed with a default divorce. If your spouse actively contests the divorce, you may need to consult an attorney.

What forms do I need to file for divorce in California?

The basic forms include the Petition (FL-100), Summons (FL-110), and if you have children, the Declaration Under UCCJEA (FL-105). You'll also need financial disclosure forms (FL-140, FL-142, FL-150) and a final Judgment (FL-180). MutualFile generates all required forms automatically based on your answers.

What is the date of separation and why does it matter?

The date of separation is the date one spouse communicated the intent to end the marriage and took actions consistent with that intent. It matters because it determines when community property stops accumulating — anything earned or acquired after this date is generally separate property.
