Child Custody in a California Divorce: Best Interests, 50/50, Mediation and Moving Away

California decides custody by one standard: the best interest of the child. There is no rule favoring mothers or fathers, no automatic 50/50 split, and no age at which a child simply chooses. Most parents settle custody themselves, often with the help of a court mediator. When they can't, a judge decides, guided by the factors in the Family Code.

Legal custody and physical custody

California separates two questions: who makes decisions for the child, and where the child lives.

Joint legal custody is common even when the child lives mainly with one parent. The statute calls the other parent's time visitation; the court's forms and self-help pages increasingly say parenting time. They mean the same thing.

The best-interest factors

Family Code § 3011(a) lists what the court must consider "among any other factors it finds relevant":

(1) The health, safety, and welfare of the child.

It continues with any history of abuse by a parent against the child, the other parent, or others close to them; "the nature and amount of contact with both parents"; and a parent's habitual or continual illegal drug use or alcohol or prescription-drug abuse.

Two policies frame those factors. Under § 3020(a), the child's health, safety and welfare are "the court’s primary concern." Under § 3020(b), the state's policy is that children have "frequent and continuing contact with both parents" after separation. When the two conflict, safety wins (§ 3020(c)).

What the court may not consider matters too. It cannot weigh a parent's sex, gender identity, gender expression or sexual orientation (§ 3011(b), § 3040(c)). A parent's immigration status does not disqualify them from custody (§ 3040(b)). And since 2024, if a parent's mental illness is a factor in the decision, the court must give that parent a list of local mental-health resources and state its reasons (§ 3040(d)).

Since January 1, 2026, the court must also consider relevant, admissible evidence that a parent has caused human trafficking of the child or the other parent (§ 3040.5).

Is California a 50/50 custody state?

No. Family Code § 3040(e) is explicit:

(e) This section establishes neither a preference nor a presumption for or against joint legal custody, joint physical custody, or sole custody, but allows the court and the family the widest discretion to choose a parenting plan that is in the best interest of the child, consistent with this section.

There is one presumption in favor of joint custody, and it depends on the parents. Under § 3080, joint custody is presumed to be in the child's best interest "where the parents have agreed to joint custody or so agree in open court." When parents disagree, the judge builds the schedule from the child's needs, not from a default split.

When a judge gives custody to one parent, § 3040(a)(1) directs the court to consider "which parent is more likely to allow the child frequent and continuing contact with the noncustodial parent." A parent who undermines the child's relationship with the other parent can hurt their own case.

Mediation comes first

If custody or visitation is contested, the court must send the parents to mediation before deciding. Family Code § 3170(a):

(a) If it appears on the face of a petition, application, or other pleading to obtain or modify a temporary or permanent custody or visitation order that custody, visitation, or both are contested, the court shall set the contested issues for mediation.

Court mediation is run by the court's Family Court Services, under the standards in Cal. Rules of Court, rule 5.210. The counties differ in one important way. Under § 3183(a), a mediator "may, consistent with local court rules, submit a recommendation to the court" if the parents do not agree; the statute calls that child custody recommending counseling. In counties whose rules do not allow it, the mediator makes no recommendation. Find out which kind your county uses before your appointment.

Cases involving domestic violence follow a separate protocol (§ 3170(b); rule 5.215), which can include separate sessions so the parents are not in the same room.

Can a child choose which parent to live with?

Not on their own, but their views count. Under § 3042(a), a child "of sufficient age and capacity to reason so as to form an intelligent preference" has their wishes considered and given "due weight." Age 14 is a milestone. Family Code § 3042(c):

(c) If the child is 14 years of age or older and wishes to address the court regarding custody or visitation, the child shall be permitted to do so, unless the court determines that doing so is not in the child’s best interest, in which case, the court shall state its reasons for that finding on the record.

Younger children may also be heard if the court finds it appropriate (§ 3042(d)). A child usually does not speak in front of the parents; the court provides another way to hear from them (§ 3042(f)). And no child is required to state a preference (§ 3042(i)).

Domestic violence

A finding of recent domestic violence changes the analysis sharply. Family Code § 3044(a):

(a) Upon a finding by the court that a party seeking custody of a child has perpetrated domestic violence within the previous five years against the other party seeking custody of the child, or against the child or the child’s siblings, or against a person in subparagraph (A) of paragraph (2) of subdivision (a) of Section 3011 with whom the party has a relationship, there is a rebuttable presumption that an award of sole or joint physical or legal custody of a child to a person who has perpetrated domestic violence is detrimental to the best interest of the child, pursuant to Sections 3011 and 3020. This presumption may only be rebutted by a preponderance of the evidence.

To overcome it, the parent who committed the violence must show that custody is in the child's best interest, and the court weighs factors such as completing a batterer's treatment program, complying with probation and protective orders, and committing no further violence (§ 3044(b)). The general policy favoring contact with both parents cannot be used to rebut the presumption. Since January 1, 2026, the factors also include whether the parent has kept firearms in violation of a restraining order (§ 3044(b)(2)(G)).

If you are in danger, you do not have to wait for the divorce. A domestic violence restraining order can be requested at any time. Under Family Code § 6222, "There is no filing fee" for the request, and under § 6323 the order can include temporary custody and visitation.

Moving away with the children

A parent with custody generally has the right to move, but the court can stop a move that would harm the child. Family Code § 7501(a):

(a) A parent entitled to the custody of a child has a right to change the residence of the child, subject to the power of the court to restrain a removal that would prejudice the rights or welfare of the child.

In practice, a proposed move-away is one of the hardest custody disputes, and judges look closely at the reasons for the move and its effect on the child's relationship with the other parent.

Notice. A custody order may require a parent to give notice before moving. Under § 3024, the court can specify that a parent must notify the other parent of a planned change of the child's residence "for more than 30 days," by mail with a return receipt requested, and "To the extent feasible, the notice shall be provided within a minimum of 45 days before the proposed change of residence so as to allow time for mediation of a new agreement concerning custody." Read your own order: its terms control.

While the divorce is pending, neither parent may take the children out of California without the other's written consent or a court order. That restriction is one of the automatic restraining orders printed on the divorce summons.

Which state decides custody

Custody jurisdiction follows the child, not the parents. Under the Uniform Child Custody Jurisdiction and Enforcement Act, as enacted in California, a child's "home state" is generally the state where the child lived with a parent "for at least six consecutive months immediately before the commencement" of the case (§ 3402(g)), and the home state ordinarily decides custody (§ 3421). A parent who has just moved to California with the children may have to litigate custody where they came from. A divorce involving minor children includes a declaration listing where they have lived (form FL-105).

Evaluations and a lawyer for the child

In hard cases a judge can order a child custody evaluation (rule 5.220), and can appoint a lawyer to represent the child (rule 5.242). Evaluation reports go in the confidential part of the court file (Family Code § 3025.5).

Custody orders can change

Custody and visitation orders are never truly final while the child is a minor. Either parent can ask the court to modify them when circumstances change, and the court looks again at what is now in the child's best interest. Parents can also agree on changes and submit them to the court as a stipulation.

Frequently asked questions

Is California a 50/50 custody state?

No. Family Code § 3040(e) establishes no preference or presumption for joint or sole custody. Joint custody is presumed best only when the parents agree to it (§ 3080). Otherwise the judge decides based on the child's best interest.

At what age can a child choose which parent to live with in California?

No age lets a child decide. A child of any age with enough maturity has their preference considered, and a child 14 or older who wants to address the court must be allowed to unless the court finds it is not in the child's best interest.

Is custody mediation mandatory in California?

Yes, when custody or visitation is contested. Section 3170 requires the court to send the parents to mediation, through the court's Family Court Services. In some counties the mediator can make a recommendation to the judge.

Do mothers get custody more often in California?

The law gives no preference to either parent. Under §§ 3011 and 3040, the court cannot consider a parent's sex or gender in deciding custody.

Can I move out of California with my child after divorce?

A custodial parent generally has the right to move, but the court can block or limit a move that would harm the child, and your order may require advance notice. During the divorce, you need written consent or a court order to take the children out of the state.

How does domestic violence affect custody in California?

If the court finds a parent committed domestic violence within the last five years, that parent is presumed unfit for sole or joint custody under § 3044. The presumption can be overcome only by showing that custody is in the child's best interest and weighing the statutory factors.

What is the difference between legal and physical custody?

Legal custody is decision-making authority over the child's health, education and welfare. Physical custody is where the child lives. Parents can share one and not the other.
