California is one of the most populous states in the country, and its divorce laws reflect a deliberate effort to balance fairness, clarity, and complexity. Whether you are ending a short marriage with no shared property or a decades-long union with real estate, retirement accounts, and children, understanding the California system before you file will save you time, money, and significant frustration.
This guide covers every major step: confirming you meet residency requirements, understanding California's community property rules, gathering the right forms (FL-100 and FL-110), paying filing fees, navigating the mandatory 6-month waiting period, and handling child custody when children are involved. We also explain exactly how DivorcePro helps you organize everything so nothing falls through the cracks.
California Residency Requirements: Two Separate Rules
California has a two-part residency requirement, and both parts must be satisfied before you can file in a particular county. This trips up many filers who assume one rule covers both.
Rule 1 — State residency: At least one spouse must have lived in California for at least 6 months immediately before filing the petition.
Rule 2 — County residency: At least one spouse must have lived in the county where you plan to file for at least 3 months immediately before filing.
Both requirements apply to the same person — you cannot satisfy the state requirement with one spouse and the county requirement with the other. If you moved to California four months ago, you do not yet qualify for state residency. If you moved counties two months ago, you do not yet qualify for county residency even if you have lived in California for years.
Acceptable documentation to prove residency includes a California driver's license or ID, voter registration card, utility bills, lease or mortgage records, or a signed declaration under penalty of perjury describing your residency history.
California's No-Fault Divorce Grounds
California is a pure no-fault divorce state. You do not need to prove adultery, abandonment, cruelty, or any other misconduct. The only legal grounds for divorce in California are:
- Irreconcilable differences — the most common ground, meaning the marriage has broken down irretrievably
- Permanent legal incapacity to make decisions — formerly called "incurable insanity," this requires medical evidence and is rarely used
In practice, nearly every California divorce is filed on the grounds of irreconcilable differences. One spouse's desire to end the marriage is sufficient — the other spouse cannot legally stop a divorce in California. Even if your spouse refuses to participate, the court can and will proceed without them.
Community Property: California's 50/50 Rule
California is one of only nine community property states in the US, and this single fact shapes everything about how divorce works here. Before you file, you need to understand the basic framework.
What Is Community Property?
Community property is everything acquired by either spouse during the marriage, regardless of whose name is on the account or title. It belongs equally to both spouses. Upon divorce, community property is divided 50/50.
This includes:
- Wages, salaries, and income earned during the marriage
- Bank accounts funded with marital income
- Real estate purchased during the marriage
- Retirement accounts and pension benefits earned during the marriage
- Businesses started or significantly grown during the marriage
- Debts incurred during the marriage (both spouses are equally liable)
- Investment accounts and stock options vested during the marriage
What Is Separate Property?
Separate property generally stays with the spouse who owns it and is not subject to equal division. Separate property includes:
- Assets owned by either spouse before the marriage
- Gifts or inheritances received by one spouse, even during the marriage
- Assets purchased entirely with separate property funds
- Assets protected by a valid prenuptial or postnuptial agreement
Equal Division in Practice
The 50/50 rule does not mean you physically split every asset in half. Spouses can negotiate a marital settlement agreement that trades one asset for another of equal value — for example, one spouse keeps the house in exchange for the other receiving a larger share of retirement accounts. What matters is that the total value is equalized. If you cannot agree, a judge will divide community assets, and California judges strictly follow the equal division mandate with very limited exceptions.
The Mandatory 6-Month Waiting Period
California imposes a mandatory waiting period: no divorce can be finalized until at least 6 months have passed from the date the respondent was served (or from the date the respondent filed a Notice of Appearance if they were not formally served). This waiting period cannot be waived by either party or by the court, for any reason.
This means even if both spouses agree on absolutely everything and submit perfect paperwork on day one, the earliest your divorce can be legally final is 6 months and one day after service. Plan your timeline accordingly.
The waiting period is not dead time. Use it to:
- Complete mandatory financial disclosures (Preliminary and Final Declaration of Disclosure)
- Negotiate and finalize your marital settlement agreement
- Resolve child custody and support arrangements
- Complete any required court-ordered mediation
- Obtain valuations for real estate, businesses, or retirement accounts
The Core California Divorce Forms: FL-100 and FL-110
California's court system uses standardized Judicial Council forms. All forms are available free at the California Courts website (courts.ca.gov). Here are the essential ones:
FL-100: Petition — Marriage/Domestic Partnership
FL-100 is the document that opens your divorce case. The petitioner (the spouse filing first) completes FL-100 and files it with the superior court clerk. It identifies both spouses, the date of marriage, the grounds for divorce (almost always irreconcilable differences), the names and ages of any minor children, and what relief you are seeking — property division, support, custody, and name changes if applicable.
FL-110: Summons (Family Law)
FL-110 is filed alongside FL-100. It is the official notice that formally informs the respondent that a divorce has been filed. The summons also contains automatic temporary restraining orders (ATROs) that take effect the moment the petition is filed and apply to both spouses immediately. These ATROs prohibit either spouse from:
- Moving children out of California without written consent or a court order
- Cashing out, borrowing against, or transferring retirement accounts
- Selling, transferring, or encumbering community property
- Canceling or changing health, auto, or life insurance policies
- Taking on new debt beyond ordinary living expenses
Violating ATROs can result in serious legal consequences, including contempt of court charges.
Other Key Forms
| Form | Purpose | When Required |
|---|---|---|
| FL-115 | Proof of Personal Service | After respondent is served |
| FL-120 | Response — Marriage/Domestic Partnership | Respondent's reply (30-day window) |
| FL-140 | Declaration of Disclosure | Both parties, mandatory |
| FL-142 | Schedule of Assets and Debts | Both parties, mandatory |
| FL-150 | Income and Expense Declaration | Both parties, mandatory |
| FL-170 | Declaration for Default or Uncontested | Uncontested or default cases |
| FL-180 | Judgment (Family Law) | Final judgment — signed by judge |
| FL-341 | Child Custody and Visitation Order | Cases with minor children |
| FL-342 | Child Support Information and Order | Cases with minor children |
| FL-343 | Spousal, Partner, or Family Support Order | If spousal support is sought |
| FW-001 | Request to Waive Court Fees | If you cannot afford filing fee |
Step-by-Step: Filing for Divorce in California
Confirm Residency and Gather Your Information
Verify you meet both the 6-month state and 3-month county residency requirements. Then collect: both spouses' full legal names and current addresses, date and place of marriage, Social Security numbers (for financial disclosures), information about all minor children (names, dates of birth, current living arrangements), and a complete preliminary inventory of assets and debts — bank accounts, real estate, vehicles, retirement accounts, credit cards, mortgages, and loans.
Complete FL-100 and FL-110
Download both forms free from courts.ca.gov. Complete FL-100 (the Petition) carefully with accurate information about your marriage, children, and what you are requesting from the court. FL-110 (the Summons) is largely pre-printed — fill in the case name and court information. Sign FL-100 before filing. Do not sign FL-110; the clerk signs or stamps it when you file.
File at the Superior Court Clerk's Office
Take your completed FL-100 and FL-110 (plus any required local forms) to the clerk's office of the superior court in your county. The filing fee is $435. The clerk stamps your copies, assigns a case number, and returns the filed documents to you. If you cannot afford the fee, file Form FW-001 (Request to Waive Court Fees) at the same time — the court will review and approve or deny the waiver, often on the same day.
Serve Your Spouse
Within 60 days of filing, you must serve your spouse with a copy of the filed FL-100, FL-110, and any other filed documents. California requires personal service — the documents must be handed directly to your spouse by someone over 18 who is NOT you. A registered process server, sheriff's deputy, or a trusted adult friend can serve the papers. Once served, the server must complete Proof of Service (FL-115), which you then file with the court. The 6-month clock starts on the date of service.
If you cannot locate your spouse, the court may allow service by publication in a newspaper, but this requires a court order and documented evidence of a good-faith search effort.
Respondent Has 30 Days to Respond
After being served, your spouse has 30 days to file a response using FL-120. If they do not respond, you can request a default using FL-165. A default means your spouse forfeits their right to participate, and the court can proceed on the terms you requested in FL-100. The 6-month waiting period still applies, and the court will independently review any child custody or support arrangements regardless of default status.
Complete Mandatory Financial Disclosures
Both spouses must exchange Preliminary Declarations of Disclosure — a package that includes FL-140, FL-142 (Schedule of Assets and Debts), and FL-150 (Income and Expense Declaration). These are served on your spouse, not filed with the court (with limited exceptions). This step is mandatory and cannot be waived except in very narrow circumstances. Failure to complete disclosures can result in sanctions and can potentially unwind a final judgment even after it is entered.

Get Your Personalized PlanNegotiate and Draft Your Settlement Agreement
If you and your spouse can agree on property division, support, and child custody, you will draft a Marital Settlement Agreement (MSA). This binding contract spells out exactly how all issues are resolved. Courts generally approve MSAs as long as they are not unconscionable and any child-related provisions meet the best-interest standard. Having an attorney review your MSA before you sign is highly advisable, even if you have managed everything else yourself.
If you cannot reach agreement, the court schedules hearings on contested issues and ultimately issues orders. Contested divorces significantly extend the timeline and cost.
Wait Out the 6-Month Period and Submit Final Judgment
Once the 6-month waiting period has elapsed, submit your final judgment paperwork. For uncontested cases this includes FL-170 (Declaration for Default or Uncontested), FL-180 (Judgment), your executed MSA, and any custody or support orders. The court reviews the documents and, if everything is in order, the judge signs FL-180. Your divorce is legally final on the date the judge signs the judgment — not when you receive the paperwork in the mail.

Additional costs can include QDRO preparation for retirement accounts ($500 – $1,500), court-ordered mediation ($100 – $300 per party per session), and appraisal fees for real estate or business valuations.
Child Custody in a California Divorce
When minor children are involved, the court's singular standard is the best interests of the child. California law presumes that children benefit from frequent and continuing contact with both parents, so sole custody arrangements that substantially exclude one parent are relatively rare absent documented safety concerns.
Legal Custody vs. Physical Custody
Legal custody refers to the right to make major decisions about the child's health, education, and welfare. California courts strongly favor joint legal custody, meaning both parents share decision-making authority equally.
Physical custody refers to where the child lives day-to-day. Arrangements range from primary residence with one parent and scheduled visitation for the other, to a true 50/50 timeshare where the child alternates between homes on equal schedules.
Parenting Plan Requirements
California requires a written parenting plan (sometimes called a custody and visitation order) that specifies:
- The regular custody schedule (weekly, bi-weekly, or another rotation)
- Holiday and school-break schedules
- How transportation between homes will be handled and who pays
- How disagreements between parents will be resolved
- Any specific conditions or restrictions relevant to the children's welfare
If parents cannot agree on a parenting plan, most California counties require mediation through the court's Family Court Services (FCS) before a judge will hold a custody hearing. Court-connected mediation is typically provided free of charge.
Child Support
California uses a statewide guideline formula to calculate child support, factoring in each parent's net disposable income and the percentage of time the child spends with each parent. Courts use approved software (DissoMaster or XSpouse) to run the calculation. While parents may agree to support above the guideline, courts are very reluctant to approve agreements below guideline amounts unless specific statutory exceptions apply.
How DivorcePro Helps You Organize Everything

Start Your DivorcePro Case Preparation PackageFrequently Asked Questions
What are the residency requirements to file for divorce in California?
At least one spouse must have lived in California for the six months immediately before filing, AND must have lived in the county where they are filing for at least three months. Both requirements must be satisfied before the court will accept your petition.
How long does a California divorce take?
California has a mandatory 6-month waiting period that begins the day the respondent is served with divorce papers. No divorce can be finalized before that period expires, even if both spouses agree on everything. Most uncontested divorces take 6 to 9 months total; contested divorces can take 1 to 3 years.
What is community property in a California divorce?
California is a community property state. Most assets and debts acquired during the marriage are considered equally owned (50/50) by both spouses and must be divided equally upon divorce. Separate property — assets owned before marriage or received as gifts or inheritance — generally stays with the original owner.
What forms do I need to file for divorce in California?
The core California divorce forms are the Petition (FL-100) and Summons (FL-110), which are filed together to open the case. You will also need proof of service, financial disclosure forms (FL-140, FL-142, FL-150), and judgment forms to finalize. If children are involved, add FL-341 (Child Custody and Visitation Order) and FL-342 (Child Support Order).
How much does it cost to file for divorce in California in 2026?
The filing fee to open a divorce case in California is $435 for the petitioner and $435 for the respondent when they file a response. Fees are set by the Judicial Council. If you cannot afford the fee, you can request a waiver using form FW-001.
