How to File for Divorce in California: Complete 2026 Guide

California divorce requires a $435 to $450 filing fee, a mandatory 6-month waiting period, and either 6 months of state residency or 3 months of county residency before filing. Under California Family Code § 2320, at least one spouse must meet these residency thresholds. The state follows a no-fault divorce system, meaning you only need to cite irreconcilable differences without proving wrongdoing. As a community property state governed by California Family Code § 760, California divides marital assets equally (50/50) upon dissolution. Starting January 1, 2026, couples who agree on all terms can file a joint petition together under Senate Bill 1427, streamlining the process significantly.

Key Facts: California Divorce at a Glance

Understanding California Divorce Requirements in 2026

California requires at least one spouse to have lived in the state for 6 continuous months and in the filing county for 3 months before submitting a divorce petition. Under California Family Code § 2320, residency means physical domicile with intent to remain indefinitely, not simply owning property or visiting occasionally. If neither spouse meets these thresholds, you may file for legal separation instead under Family Code § 2321, which has no residency requirement, then convert to dissolution once residency is established.

California operates exclusively as a no-fault divorce state. You cannot allege adultery, abandonment, or cruelty as grounds for divorce. The only legal ground is irreconcilable differences under Family Code § 2310, meaning the marriage has broken down irretrievably. This approach reduces courtroom conflict and eliminates the need to prove wrongdoing. Approximately 98% of California divorces proceed on irreconcilable differences without contested fault allegations.

The mandatory 6-month waiting period begins when your spouse is formally served with the Summons and Petition or makes their first court appearance, whichever occurs first. Under Family Code § 2339, no judge can waive, shorten, or expedite this timeframe under any circumstances. Even couples who agree on every issue must wait the full 6 months and 1 day before their divorce becomes final.

How to File for Divorce in California: Step-by-Step Process

Filing for divorce in California involves completing Form FL-100 (Petition for Dissolution of Marriage), paying $435 to $450 in court fees, and serving your spouse within 60 days. The entire process typically takes 7 to 9 months for uncontested cases and 18 to 24 months for contested divorces involving custody disputes or complex assets. Understanding each step helps you navigate the system efficiently and avoid common delays that extend timelines by 3 to 6 months.

Step 1: Complete Required Forms

You must file Form FL-100 (Petition for Dissolution of Marriage) to initiate your case. This three-page document requests basic information about your marriage, grounds for divorce, and the relief you seek. Use your full legal name and provide a valid mailing address where you will receive court notices throughout the proceedings. You may use a P.O. Box, relative's address, or friend's address if you prefer privacy or are in transition.

File Form FL-110 (Summons) alongside your petition. The Summons imposes automatic temporary restraining orders (ATROs) on both spouses immediately upon filing. These orders prohibit removing minor children from California without consent, transferring or concealing community property, changing insurance beneficiaries, and creating non-business debt. Violating ATROs can result in contempt charges and adverse rulings.

If you have minor children, you must also file Form FL-105 (Declaration Under Uniform Child Custody Jurisdiction and Enforcement Act). This form provides information about where your children have lived for the past 5 years and identifies any other custody proceedings involving them.

Step 2: File with the Superior Court

Submit your completed forms to the Superior Court clerk in the county where you or your spouse reside. The filing fee ranges from $435 to $450 depending on your county. San Francisco, San Bernardino, and Riverside counties charge additional local fees. If you cannot afford the filing fee, California offers a fee waiver program using Judicial Council Form FW-001. Qualifying factors include receiving public benefits, having household income below 125% of the federal poverty level, or demonstrating inability to pay basic living expenses.

The clerk will stamp your documents with a case number and return conformed copies. Keep these copies safe as you will need them for service and future filings. Most California courts now accept electronic filing through approved vendors, which can save time and provide instant confirmation of filing.

Step 3: Serve Your Spouse

California law requires personal service of the Summons and Petition on your spouse within 60 days of filing under Family Code § 2330. The 6-month waiting period does not begin until service is complete. You cannot serve the documents yourself. Instead, use any person over 18 who is not a party to the case, a registered process server ($25 to $100 per attempt), or the county sheriff ($40 in most counties).

After service, the server must complete Form FL-115 (Proof of Service of Summons) and file it with the court. If your spouse cannot be located, you may request permission to serve by publication in a local newspaper, though this requires a court order and extends your timeline by 4 to 6 weeks.

Step 4: Complete Financial Disclosures

California mandates two rounds of financial disclosure in every divorce case. Under Family Code § 2104, you must serve (not file) your Preliminary Declaration of Disclosure within 60 days of filing. This requirement cannot be waived under any circumstances. The disclosure package includes Form FL-142 (Schedule of Assets and Debts) or Form FL-160 (Property Declaration), Form FL-150 (Income and Expense Declaration), and two years of tax returns.

List every asset regardless of whether you consider it separate or community property. California courts impose fiduciary duties on both spouses under Family Code § 1101. If you conceal property, the court may award 100% of that asset to your spouse plus attorney fees. The Final Declaration of Disclosure must be served before entry of judgment, though parties can waive this requirement by written stipulation.

Step 5: Wait for Response or Default

Your spouse has 30 days to file a Response (Form FL-120) after being served, or 35 days if served by mail. If they file a response, you have a contested case requiring negotiation or trial. If they do not respond within the deadline, you may request entry of default using Form FL-165 (Request to Enter Default).

A default judgment allows you to proceed on the terms proposed in your petition without your spouse's participation. However, California courts disfavor true defaults and will give your spouse opportunities to participate even after missing the initial deadline. Default divorces still require the 6-month waiting period before finalization.

Step 6: Negotiate or Litigate

If your spouse files a response, you must resolve disputed issues through negotiation, mediation, or trial. California requires mediation for custody disputes under Family Code § 3170. Property and support issues may proceed directly to trial if settlement fails. Approximately 95% of California divorces settle before trial through attorney negotiations or mediation.

For uncontested cases where both spouses agree, you can prepare a Marital Settlement Agreement covering property division, support, and custody. File this agreement with Form FL-170 (Declaration for Default or Uncontested Dissolution) and Form FL-180 (Judgment). Most uncontested cases finalize without a court hearing.

New Joint Petition Process (Effective January 1, 2026)

Starting January 1, 2026, California offers a streamlined joint petition option under Senate Bill 1427 for couples who agree on all terms. Under amended Family Code §§ 2330, 2331, 2342, both spouses can file a single petition together, eliminating the need for formal service. Filing the joint petition constitutes service on both parties, immediately starting the 6-month waiting period.

This process differs from summary dissolution, which is limited to couples married less than 5 years with no children, less than $47,000 in community property, and less than $6,000 in community debt. The new joint petition has no such restrictions, making it available to long-term spouses, parents, and couples with significant assets. However, if either party later files an amended petition or response, the case reverts to the traditional adversarial process.

California Property Division: Community Property Rules

California is one of 9 community property states, meaning all property acquired during marriage is presumed to belong equally to both spouses and must be divided 50/50 upon divorce. Under California Family Code § 760, wages, bonuses, retirement contributions, real estate, and business interests acquired while married constitute community property regardless of which spouse earned or purchased the asset. This presumption applies to property acquired while domiciled in California.

Separate property includes assets owned before marriage, inheritances, and gifts received by one spouse alone. To claim an asset as separate property, you must trace its origins with clear evidence. The burden of proof falls on the spouse asserting separate property status. Commingling separate property with community funds can transform it into community property, making meticulous record-keeping essential.

Beginning July 1, 2026, California's Digital Financial Assets Law expands how courts address cryptocurrency, NFTs, and digital property. The law requires disclosure of access credentials and establishes valuation standards for digital assets in divorce proceedings. Courts may appoint experts to value complex digital holdings.

Spousal Support (Alimony) in California

California courts determine spousal support based on 14 factors listed in Family Code § 4320. There is no strict formula for permanent support; judges have broad discretion to set amounts based on each marriage's specific financial circumstances. Temporary support during divorce proceedings uses a different calculation, typically 40% of the payor's net income minus 50% of the payee's net income.

Key factors include each spouse's earning capacity, the marital standard of living, duration of the marriage, domestic violence history, tax consequences, and each party's assets and obligations. For marriages lasting 10 or more years (long-term marriages), courts typically retain jurisdiction indefinitely and may order permanent support. For shorter marriages, support generally lasts half the length of the marriage.

As of January 1, 2026, spousal support payments are not tax-deductible for the payor and not taxable income for the recipient on California state taxes, matching federal law. Orders finalized before 2026 may still follow prior tax treatment if not modified.

Child Custody in California: Best Interest Standard

California courts determine custody based exclusively on the child's best interest under Family Code § 3011. Judges must consider the child's health, safety, and welfare; each parent's history of abuse or domestic violence; substance abuse issues; and the nature of each parent's relationship with the child. California shows no preference for mothers over fathers. Both parents have equal rights to custody under state law.

Physical custody determines where children live day-to-day. Legal custody determines who makes major decisions about education, healthcare, and religious upbringing. Courts prefer joint custody arrangements that allow children to maintain relationships with both parents unless evidence shows joint custody would harm the child's health, safety, or welfare.

Children aged 14 and older may express their custodial preferences, and courts must consider those wishes unless doing so would harm the child. Younger children may speak through a minor's counsel appointed to represent their interests. California requires mediation before any contested custody hearing under Family Code § 3170.

Effective January 1, 2026, amended Family Code §§ 3044 and 6389 expand firearm restrictions in domestic violence custody cases. Courts must now consider violations of firearm restrictions under Code of Civil Procedure § 527.9 and Penal Code § 18120 when making custody determinations.

Child Support Calculation in California

California uses a mandatory statewide guideline formula under Family Code § 4055. The algebraic formula is CS = K[HN - (H%)(TN)], where CS equals child support amount, K equals the allocation factor based on income and number of children, HN equals the high earner's net monthly disposable income, H% equals the high earner's percentage of custodial time, and TN equals total net disposable income of both parents.

Courts use certified calculators like DissoMaster to compute guideline support. Six calculators are currently certified for California court use, with certifications expiring March 31, 2026. Parents earning below full-time minimum wage ($2,929 net monthly as of January 2026 based on $16.90/hour) receive a low-income adjustment that reduces their obligation.

Senate Bill 343 updated the guideline formula in September 2024 for the first time since 1992, adjusting income thresholds and K-factor multipliers to reflect current economic conditions. Senate Bill 1055, effective January 2025, prohibits driver's license suspension for parents earning below 70% of area median income and extends the non-payment threshold from 30 days to 6 months.

Timeline: How Long Does Divorce Take in California?

The minimum possible timeline is exactly 6 months and 1 day from service to final judgment. This applies only to perfectly cooperative uncontested cases with no court backlog. Realistically, 7 to 9 months is typical for the simplest uncontested divorce due to document processing times and court scheduling.

Contested divorces involving custody disputes routinely take 18 months to 2 or more years. Complex property cases with business valuations, hidden assets, or retirement account divisions add 3 to 6 months beyond typical timelines. Each motion, continuance, or discovery dispute can extend proceedings by weeks or months.

Frequently Asked Questions

How much does it cost to file for divorce in California?

The court filing fee for divorce in California ranges from $435 to $450 depending on your county, with San Francisco, San Bernardino, and Riverside charging additional local fees. If your spouse files a response, they pay the same amount, totaling $870 to $900 in court fees alone. Fee waivers are available for those who qualify based on income or public benefits using Form FW-001.

Can I file for divorce in California if I just moved here?

You cannot file for dissolution of marriage until you have resided in California for at least 6 months and in your filing county for at least 3 months. However, you may file for legal separation immediately with no residency requirement under Family Code § 2321, then convert to dissolution once you meet the thresholds.

How long do I have to be separated before filing for divorce in California?

California has no mandatory separation period before filing. You can file for divorce while still living together. The 6-month waiting period begins after filing and serving your spouse, not from the date of separation. Your date of separation affects property characterization but does not delay filing.

What is the new joint petition option effective January 2026?

Senate Bill 1427 allows couples who agree on all divorce terms to file a single joint petition together starting January 1, 2026. This eliminates the need for one spouse to serve the other, as filing constitutes service. Unlike summary dissolution, there are no restrictions on marriage length, children, or asset values. The 6-month waiting period still applies.

How is property divided in a California divorce?

California is a community property state requiring 50/50 division of all assets and debts acquired during marriage. Under Family Code § 760, wages, retirement contributions, real estate, and business interests acquired while married are presumed community property regardless of title. Separate property (pre-marriage assets, inheritances, gifts) remains with the original owner.

Do I need a lawyer to file for divorce in California?

You are not required to hire an attorney for divorce in California. Many uncontested cases proceed successfully with self-help resources from the California Courts website (selfhelp.courts.ca.gov). However, contested cases, high-asset divorces, and custody disputes benefit significantly from legal representation. Family Law Facilitators at each courthouse can assist self-represented parties with forms and procedures at no cost.

How is child support calculated in California?

California uses a mandatory statewide guideline formula under Family Code § 4055. The calculation considers each parent's net disposable income, the percentage of custodial time with each parent, and a K-factor based on combined income and number of children. Courts use certified calculators like DissoMaster to compute support. The current low-income threshold is $2,929 net monthly (based on $16.90/hour minimum wage effective January 2026).

Can I get alimony in California?

Spousal support (alimony) depends on 14 factors in Family Code § 4320, including earning capacity, marital standard of living, marriage duration, and domestic violence history. For marriages of 10+ years, courts may order indefinite support. For shorter marriages, support typically lasts half the marriage length. There is no strict formula; judges have broad discretion based on case specifics.

What happens if my spouse does not respond to divorce papers?

If your spouse fails to file a Response (Form FL-120) within 30 days of service (35 days if served by mail), you may request entry of default using Form FL-165. A default judgment allows you to finalize the divorce on the terms in your petition without your spouse's participation. The 6-month waiting period still applies to default divorces.

How do I serve divorce papers in California?

You must have someone other than yourself personally deliver the Summons and Petition to your spouse within 60 days of filing. Acceptable servers include any adult (18+) not party to the case, a registered process server ($25-$100), or the county sheriff ($40). After service, the server completes Form FL-115 (Proof of Service) for filing with the court.
