Divorce is hard. When children are involved, it's harder. Every decision you make — where you live, how you split time, who pays what — directly affects kids who had no say in any of it. California family courts understand this, and they organize every ruling around a single standard: the best interests of the child. The good news is that most California parents navigate divorce without a lawyer. This guide gives you a practical, step-by-step checklist to do it right.

Why Courts Focus on the Children's Best Interests
California Family Code §3020 makes the policy explicit: the state's highest priority in custody matters is ensuring the health, safety, and welfare of the child. Courts are required to protect children from abuse, domestic violence, and substance abuse — and to give them frequent and continuing contact with both parents when that contact is safe.
When a judge has to decide custody, they apply the factors listed in Family Code §3011, including:
- The child's health, safety, and welfare
- Any history of abuse or domestic violence by either parent
- The nature and amount of contact the child has with each parent
- Habitual or continual illegal use of controlled substances or alcohol by either parent
Beyond these factors, courts strongly favor stability and continuity. A judge does not want to disrupt a child's school, friendships, or routines any more than necessary. This is why parents who can demonstrate a stable home environment — and who cooperate with the other parent — tend to fare better in contested custody proceedings.

The Complete Pre-Filing Checklist
Before you file any paperwork, get organized. The more prepared you are before your first court date, the smoother the process goes.
- Gather financial documents — tax returns (last 2–3 years), recent pay stubs, bank statements, credit card statements, and any records of self-employment income
- Document all property and debts — list every asset and liability you and your spouse hold, separately or jointly
- Identify all assets, including retirement accounts — 401(k)s, pensions, IRAs, and similar accounts may require a Qualified Domestic Relations Order (QDRO) to divide without tax penalties
- Establish a separate housing situation or interim parenting schedule — courts look at what's already working when making initial orders
- Document your child's school and medical providers — know the names, addresses, and contacts for your child's school, pediatrician, therapist, and any specialists
- Open an individual bank account — if you don't have one in your name only, open one now; you'll need it to manage your own finances during the process
- Photograph shared property — take inventory of furniture, electronics, jewelry, and other personal property before anything goes missing
Being organized now saves you time, legal costs, and conflict later.
Custody Types in California
California law distinguishes between two types of custody, each with two possible arrangements.
| Type | Options | What It Means |
|---|---|---|
| Legal Custody | Sole (FC §3006) / Joint (FC §3003) | Who makes major decisions about education, healthcare, and religion |
| Physical Custody | Sole (FC §3007) / Joint (FC §3004) | Where the child primarily lives |
Joint legal custody (the most common outcome) means both parents share decision-making authority. Either parent can typically handle day-to-day decisions on their own; major decisions — like changing schools or elective surgery — require agreement.
Joint physical custody means the child spends significant time with both parents, though not necessarily 50/50. Courts rarely order a rigid equal split unless the parents live close to each other and can make it work logistically.
Sole custody (legal or physical) gives one parent primary authority or primary residence. Courts award sole physical custody when joint custody would not serve the child's best interests — for example, when one parent is unavailable, unsafe, or has a history of abuse.
How to Create a Parenting Plan
A parenting plan — also called a custody and visitation agreement — is the document that spells out exactly how custody will work day to day. Courts strongly prefer that parents agree on a plan rather than litigate. A contested custody trial is expensive, stressful, and unpredictable. A negotiated plan gives both parents more control over the outcome.
A complete parenting plan should cover:
- Regular schedule — which parent has the child on which days during the school year
- Holiday and vacation schedule — how major holidays (Thanksgiving, Christmas, spring break, summer vacation) are divided or alternated
- Decision-making authority — who has authority over school, medical, extracurricular, and religious decisions, and what happens when parents disagree
- Communication rules — how and when each parent can contact the child, and how the parents communicate with each other about the child
- Transportation — who drives the child between households, where exchanges happen, and what to do if someone is late
- Dispute resolution — how disagreements about the plan will be handled (mediation is often required before returning to court)
If you and your co-parent can reach agreement on a plan, a judge will almost always approve it. If you can't agree, the court will order mediation through the Family Court Services office before setting a contested hearing.
Child Support Basics
California uses a mandatory guideline formula to calculate child support — set out in Family Code §4055. The formula considers:
- Both parents' net disposable incomes — after taxes, mandatory deductions, and certain expenses
- Timeshare percentage — the percentage of time the child spends with each parent directly affects the support calculation
- Add-on expenses — childcare costs for work or training, unreimbursed healthcare expenses, and extraordinary educational or special needs costs are added on top of base support
Child support is not negotiable below the guideline amount in most cases. Courts treat the formula as the floor. If you and your co-parent agree on a higher amount, that's allowed — but not lower unless specific legal exceptions apply.
The Department of Child Support Services (DCSS) can enforce child support orders through wage garnishment, tax refund interception, and license suspension. If you need to modify support later — because income or custody time has changed — see our guide on California child support modification.
The Documents You'll Need to File
For a divorce with children in California, you'll need to file several forms. The core set includes:
- FL-100 — Petition for Dissolution of Marriage (the initial filing)
- FL-110 — Summons (Family Law)
- FL-105 — Declaration Under Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA)
- FL-140 — Declaration of Disclosure (sent to your spouse, not filed with the court)
- FL-150 — Income and Expense Declaration (filed with the court; critical for child and spousal support)
- FL-160 — Property Declaration
- FL-341 — Stipulation and Order for Custody and/or Visitation of Children (the parenting plan order)
- FL-342 — Child Support Information and Order Attachment
The FL-105 UCCJEA Declaration is required whenever minor children are involved — it establishes that California is the correct state to decide custody. Courts will not finalize custody orders without it.
Getting these forms right the first time avoids rejections, delays, and re-filing fees.

Common Mistakes Divorcing Parents Make
Avoiding these mistakes can save you months of delays and thousands of dollars in avoidable conflict:
-
Not documenting the parenting schedule early — whatever informal arrangement you establish during separation becomes the baseline. Courts may be reluctant to change something that's already working for the children.
-
Failing to disclose all assets — California requires full financial disclosure by both spouses. Hiding or failing to list assets (a side business, a retirement account, cryptocurrency) can result in the court setting aside the judgment entirely.
-
Letting emotions drive custody decisions — using custody as leverage in property negotiations, or making custody decisions out of anger rather than the child's best interests, almost always backfires in court.
-
Ignoring the tax implications — child support is neither deductible for the payer nor taxable income for the recipient. Spousal support (alimony) has different tax treatment depending on when the divorce is finalized. Know the difference before you agree to anything.
-
Not getting the parenting plan in writing — a verbal agreement between parents is not enforceable. Only a court order can be enforced if one parent stops following through.
-
Skipping the Preliminary Declaration of Disclosure — the FL-140 and supporting financial disclosures are mandatory. Skipping them delays your case and can expose you to sanctions.
How Long Does Divorce With Children Take in California?
Family Code §2339 imposes a mandatory 6-month waiting period before a California divorce can be finalized — starting from the date the respondent is served with the divorce petition. This is a hard floor; no judge can waive it.
That said, 6 months is the minimum, not the average. Here's how the timeline typically plays out:
- Uncontested divorce (both parties agree on all issues): 6–9 months from filing to judgment
- Contested divorce (disagreements on custody, support, or property): 12–24+ months, depending on court calendar and complexity
- Cases with temporary orders: Courts can issue temporary custody, support, and restraining orders much earlier — sometimes within weeks of filing — so children and finances have a framework while the case resolves
The single biggest factor in how long your divorce takes is whether you and your co-parent can reach agreement. Every contested issue adds months and thousands of dollars. Mediation is almost always faster and cheaper than litigation.

Frequently Asked Questions
Q: Can I move out of state with my child during the divorce? Not without permission. Once a custody case is pending in California, you generally cannot remove a child from the state without either written consent from the other parent or a court order. Moving a child out of state without permission can result in serious legal consequences, including the court returning the child and sanctions against you.
Q: What if we can't agree on a parenting plan? California courts require parents to attend mediation through Family Court Services before a contested custody hearing. A mediator will work with both of you to try to reach agreement. If mediation fails, the case goes to a hearing and a judge decides. The court may also appoint a minor's counsel — an attorney for the child — in high-conflict cases.
Q: Does the child get to choose which parent to live with? A child's preference can be considered, but it is not controlling. Under Family Code §3042, courts must consider the wishes of a child who is of sufficient age and capacity to form an intelligent preference. There is no magic age where a child's preference becomes binding — a judge evaluates the child's maturity and reasoning alongside all other best-interests factors.
Q: Can child support be modified later? Yes. Either parent can request a modification of child support when there has been a material change in circumstances — such as a significant change in income, a change in the custody timeshare, or a change in the child's needs. Modifications require a court order; you cannot modify support by verbal agreement alone. See our guide on California child support modification for the full process.
Q: Do I need a lawyer for divorce with children in California? You are not required to have an attorney. Many California parents complete their divorce without one using self-help resources, court facilitator offices, and document preparation services. If custody or property is genuinely contested, consulting a family law attorney for at least a limited-scope consultation is worthwhile. If both parents are largely in agreement, a self-represented approach with properly prepared documents is entirely viable.
