Getting Divorced with Children in California (2026 Guide)

Getting divorced with children in California requires a $435 filing fee, a six-month state residency, a mandatory six-month waiting period, and a court-approved parenting plan. Every custody decision follows the best-interest-of-the-child standard under Cal. Fam. Code § 3011. Parents with contested custody must attend mandatory mediation through Family Court Services before any hearing under Cal. Fam. Code § 3170.

Divorce with children in California adds three layers to an already complex process: legal custody (decision-making), physical custody (where the child lives), and child support calculated under the statewide guideline in Cal. Fam. Code § 4055. As of September 1, 2024, Senate Bill 343 recalibrated the support formula for the first time in 32 years, raising payments at most income levels. This guide explains the full process, the costs, the timeline, and the parenting-plan requirements that govern divorce with children California families face in 2026.

Key Facts: Divorce With Children in California

What Are the Residency Requirements to File for Divorce With Children in California?

To file for divorce in California, one spouse must have lived in California for at least six months and in the filing county for at least three months immediately before filing, under Cal. Fam. Code § 2320. Only one spouse needs to meet these requirements. These residency rules apply identically whether or not children are involved.

Residency means actual domicile, not mere physical presence. California courts examine where you pay taxes, your voter registration, and your intent to remain in the state indefinitely. Occasional work travel or a once-a-year vacation home does not establish domicile. If spouses live in different counties, you may file in the county where either spouse has lived for three months. A residency defect is waived unless your spouse raises it within the 30-day response window by filing a motion to quash. If you have not yet met the six-month requirement but need to act, you can file for legal separation — which has no residency prerequisite — and later amend the petition to a dissolution once you qualify.

How Much Does It Cost to Get Divorced With Children in California?

The base filing fee for divorce in California is $435 for the petition (Form FL-100), with another $435 if your spouse files a response, for $870 in court costs. As of March 2026, this fee is uniform across all 58 counties. A major 2026 change under Senate Bill 1427 lets fully agreeing couples file a Joint Petition (Form FL-700) for a single shared $435 fee, cutting court costs in half and eliminating formal service.

Beyond filing fees, divorce with children carries additional expenses. Motions cost roughly $60 each. Process-server fees run $50–$100 for the county sheriff or $75–$200 for a private server, since California law prohibits self-service of divorce papers. Custody mediation through Family Court Services is provided at no cost to the parties. Total court fees for a contested divorce can exceed $1,000, and that figure excludes attorney fees, custody evaluations, and minor's counsel. Fee waivers are available: if you receive Medi-Cal or CalWORKs you automatically qualify, and you can also file Form FW-001 to request a waiver based on income or hardship. As of March 2026 — verify with your local clerk, as counties may add minor administrative charges.

How Long Does a Divorce With Children Take in California?

California imposes a mandatory waiting period of six months and one day from the date the responding spouse is served, under Cal. Fam. Code § 2339. No divorce can be finalized faster, even when both spouses agree on everything. This cooling-off period applies to every dissolution, regardless of whether children are involved.

In practice, the timeline depends on conflict level. An uncontested divorce where parents agree on custody, support, and property typically finalizes near the six-month minimum. A contested divorce requiring custody mediation, financial discovery, and trial commonly takes 12 to 18 months. Custody disputes are the single biggest driver of delay because California requires mediation through Family Court Services before any contested custody hearing. The table below compares the two paths.

What Are the Types of Child Custody in California?

California recognizes four custody types: joint legal, sole legal, joint physical, and sole physical custody. Legal custody is the right to make decisions about a child's health, education, and welfare under Cal. Fam. Code § 3003. Physical custody determines where the child lives under Cal. Fam. Code § 3007. Courts strongly favor joint legal custody absent safety concerns.

These categories combine in practice. Many California families share joint legal custody — both parents make major decisions together — while one parent holds primary physical custody and the other has a defined parenting-time schedule. Joint physical custody does not require a precise 50/50 split; it means the child spends significant time with both parents. Sole physical custody places the child primarily with one parent, with the other receiving visitation. Under Cal. Fam. Code § 3011, the court must consider the child's health, safety, and welfare, any history of abuse, and habitual substance abuse. The statute prohibits courts from considering a parent's sex, gender identity, gender expression, or sexual orientation when determining custody. Children aged 14 or older may address the court to express their preference, though that preference is only one factor among many.

What Is the Best-Interest-of-the-Child Standard in California?

Every custody decision in California is governed by the best-interest-of-the-child standard, codified primarily in Cal. Fam. Code § 3011 and Cal. Fam. Code § 3020. Section 3020 declares it state public policy to ensure children have frequent and continuing contact with both parents — except when contact would harm the child, in which case safety controls.

The standard is not a single definition but a compilation of statutory factors and case law. Under Section 3011, the court must consider the health, safety, and welfare of the child; any history of abuse by a person seeking custody against the child or against the other parent, a current spouse, cohabitant, or dating partner; the nature and amount of contact with both parents; and the habitual or continual illegal use of controlled substances or alcohol. When the policy of frequent contact conflicts with the policy of protecting the child, Cal. Fam. Code § 3020 requires the court to prioritize the health, safety, and welfare of the child and all family members. Where domestic violence has occurred within the prior five years, Cal. Fam. Code § 3044 creates a rebuttable presumption against awarding custody to the abusive parent.

What Is Mandatory Custody Mediation in California?

California law requires custody mediation before any court hearing on a contested custody or visitation issue, under Cal. Fam. Code § 3170. When the court sees that custody or visitation is contested, it must set the matter for mediation. Parents cannot proceed to a custody hearing without first attending mediation, which is provided at no cost through Family Court Services (FCS).

Mediation administration varies by county. The service is called Family Court Services Mediation, Child Custody Recommending Counseling (CCRC), or Confidential Mediation depending on the court. The critical distinction is between recommending counties and confidential counties. In a recommending county, the mediator prepares a written report and custody recommendation that goes to the judge, and statements made during mediation are not confidential. In a confidential county, discussions stay private and the mediator makes no recommendation to the court. FCS mediators are court-employed mental-health professionals who remain neutral and cannot give legal advice. The process generally follows three steps: orientation, a meeting with the mediator, and creation of a parenting plan. Effective 2026, California also requires mandatory mediation before any relocation (move-away) hearing and provides expedited scheduling for those cases.

What Must a California Parenting Plan Include?

A California parenting plan is a written agreement or court order that specifies the custody schedule, holiday and vacation arrangements, decision-making authority, communication rules, and dispute-resolution procedures. At minimum, the plan must distinguish legal custody under Cal. Fam. Code § 3003 from physical custody under Cal. Fam. Code § 3007. Courts review every plan against the best-interest standard.

A strong parenting plan addresses the realities of co-parenting in detail. It sets a regular weekday and weekend schedule, allocates specific holidays and school breaks, defines transportation and exchange logistics, and establishes how parents will communicate about the child. In 2026, California judges expect more granular, safety-conscious plans that clearly separate decision-making authority from residential time. The plan should also specify how disputes are resolved — often through a return to mediation before any court filing. Once both parents sign and the judge approves, the parenting plan becomes a binding court order. Either parent can later seek modification by showing a significant change in circumstances affecting the child's best interest. Self-represented parents can use Judicial Council Form FL-341 (the standard child custody and visitation attachment) as a template.

How Is Child Support Calculated in California?

California calculates child support using a mandatory statewide guideline formula under Cal. Fam. Code § 4055. The formula is expressed as CS = K[HN − (H%)(TN)], where K is the combined income allocated to support, HN is the higher earner's net monthly disposable income, H% is the higher earner's share of parenting time, and TN is total net income of both parents. Net income — not gross — drives the calculation.

Effective September 1, 2024, Senate Bill 343 overhauled this formula for the first time in 32 years. The reform updated the K-factor income bands, raising support payments at most income levels. It made proportional sharing of add-on expenses — such as childcare and uninsured medical costs — the default based on each parent's share of post-tax income, replacing the old 50/50 default under Cal. Fam. Code § 4061. Work-related childcare costs are now presumed reasonable. The reform also expanded the low-income adjustment for parents earning at full-time minimum wage. Since April 1, 2025, courts use the certified XSpouse software (which replaced DissoMaster) to run these calculations. Parenting time directly affects the amount: the more overnights a parent has, the lower their guideline obligation, which is why an accurate parenting plan matters financially as well as practically.

How Does Property Division Affect Families With Children?

California is a community property state, meaning assets and debts acquired during the marriage are divided equally — 50/50 — upon divorce under Cal. Fam. Code § 2550 and Cal. Fam. Code § 760. Separate property owned before marriage or received by gift or inheritance stays with the original owner. For families with children, the marital home is often the most consequential asset.

Courts may temporarily depart from a strict equal division when children are involved. Under Cal. Fam. Code § 3800 and related provisions, a judge can award the custodial parent temporary exclusive use of the family home — a "deferred sale of home order," sometimes called a Duke order — to minimize disruption to the children's schooling and stability. This does not change ultimate ownership; it delays the sale until a triggering event, such as the youngest child reaching a set age. Child support and spousal support are calculated separately from property division. Because community property division can affect each parent's net income, and net income drives the child support guideline, these issues are interconnected and benefit from coordinated handling.

How Do You File for Divorce With Children in California?

To start a divorce with children in California, the petitioner files Form FL-100 (Petition — Marriage/Domestic Partnership) plus Form FL-105 (Declaration Under UCCJEA) for the children, pays the $435 fee, and serves the other spouse. The UCCJEA declaration establishes the court's jurisdiction over custody by documenting where the children have lived. As of March 2026 — verify forms with your local clerk.

The sequence proceeds in stages. After service, the responding spouse has 30 days to file Form FL-120. Both parents must complete preliminary financial disclosures (Forms FL-140, FL-142 or FL-150, and FL-160) — a non-waivable requirement that affects support calculations. If custody is contested, the court refers parents to Family Court Services mediation before any hearing. Parents who reach agreement submit a written parenting plan and stipulated judgment; those who cannot proceed to a custody hearing or trial. The earliest a judgment can be entered is six months and one day after service. Fully agreeing couples can use the new 2026 Joint Petition (Form FL-700) to file jointly for a single $435 fee and skip formal service entirely. Throughout, the best-interest standard under Cal. Fam. Code § 3011 governs every custody and visitation decision.
