Child Custody in California (2026)

Overview of California Custody Law

California family courts decide all custody matters based on the best interests of the child, as defined in Family Code Section 3011. The state favors arrangements that allow children to have frequent and continuing contact with both parents, and judges have broad discretion to craft orders that fit each family’s circumstances. California is a no-fault state, which means marital misconduct generally does not factor into custody decisions unless it directly affects the child’s welfare.

Custody disputes in California are governed primarily by California Family Code Sections 3010 through 3049 (general custody provisions) and Sections 3080 through 3089 (joint custody provisions). Understanding these statutes is the starting point for any parent navigating the system.

Types of Custody Recognized in California

California law distinguishes between two dimensions of custody: legal custody and physical custody. Each can be awarded jointly or solely.

• Legal custody refers to the right to make major decisions about the child’s health, education, and welfare. Joint legal custody means both parents share this authority.
• Physical custody refers to where the child lives. Joint physical custody means the child spends significant time with each parent, though the split does not have to be exactly equal.

A common arrangement is joint legal custody with primary physical custody to one parent and a visitation schedule for the other. Courts can also award sole legal and sole physical custody to one parent when circumstances warrant it — for example, when there is a history of domestic violence or substance abuse.

For a broader look at how these terms apply nationwide, see our guide on child custody laws explained.

Custody Presumptions

Under Family Code Section 3080, there is a presumption that joint custody is in the child’s best interest when both parents agree to a joint custody arrangement. This presumption does not apply when parents disagree — in that situation, the court evaluates the evidence and makes its own determination.

There is also a strong presumption under Family Code Section 3044 that awarding custody to a parent who has perpetrated domestic violence within the past five years is detrimental to the child. That parent bears the burden of overcoming the presumption by a preponderance of the evidence.

Best Interests Factors

California Family Code Section 3011 directs courts to consider the following when determining the child’s best interests:

• The health, safety, and welfare of the child
• Any history of abuse by a parent against the child, the other parent, or any other person (including a current partner or household member)
• The nature and amount of contact with each parent
• Any history of substance abuse by either parent
• The child’s need for stability and continuity

Courts also weigh each parent’s willingness to support the child’s relationship with the other parent. A parent who actively undermines or obstructs the other parent’s time may find that behavior counted against them.

Child’s Preference

California does not set a specific age at which a child may choose which parent to live with. Under Family Code Section 3042, the court must consider the wishes of a child who is mature enough to form an intelligent preference. In practice, courts tend to give more weight to the preferences of children who are roughly 14 and older, but there is no bright-line rule. A judge may hear from a younger child if the child demonstrates sufficient understanding.

The child’s preference is only one factor among many. It is never the sole basis for a custody order.

The Role of Family Court Services and Recommending Counselors

One of the most distinctive features of California’s custody system is the role played by Family Court Services (FCS) and recommending counselors. Under Family Code Section 3170, when parents cannot agree on custody or visitation, the court refers the case to FCS — a department within each Superior Court staffed by licensed mental health professionals.

In California, counties are divided into two categories based on how FCS operates. In non-recommending counties (sometimes called “mediation-only” counties), the FCS mediator helps parents negotiate but does not share any information with the judge if mediation fails. The process is confidential, and the mediator’s role ends when mediation concludes. San Francisco and several Northern California counties follow this model.

In recommending counties — including Los Angeles, Orange, San Diego, and many others — the FCS counselor serves a dual role. They first attempt to help parents reach an agreement through mediation. If mediation fails, the counselor conducts interviews, may speak with the children, and then prepares a written recommendation to the court about what custody and visitation arrangement would serve the child’s best interests. These recommendations carry significant weight with judges. Research on recommending counties has found that judges adopt FCS recommendations in a large majority of cases, making the FCS appointment one of the most consequential steps in a contested California custody case.

Beyond FCS, the court may appoint a child custody evaluator under Family Code Section 3110 for more complex cases. A custody evaluation is a comprehensive investigation that may include psychological testing, home visits, interviews with collateral contacts (teachers, therapists, family members), and a detailed written report. Evaluations are typically ordered in high-conflict cases or when there are allegations of abuse, mental illness, or substance abuse that FCS cannot adequately assess during the shorter mediation process.

Mandatory Mediation

California requires mediation before any contested custody or visitation hearing. Under Family Code Section 3170, when parents cannot agree on custody or parenting time, the court refers the matter to a mediator — typically through the court’s Family Court Services department. Mediation is free through the court system. Parents who prefer a private mediator may hire one at their own expense, but they must still comply with the court-ordered mediation requirement.

Whether mediation is confidential depends on the county, as explained in the FCS section above. Parents should understand their county’s rules before attending their first session, since the stakes differ significantly between recommending and non-recommending counties.

Relocation Rules

A parent who has custody and wants to move a significant distance must provide 45 days’ written notice to the other parent before the move, as required by Family Code Section 3024. If the non-moving parent objects, the court will hold a hearing to decide whether the relocation serves the child’s best interests.

The key factors in relocation cases include the reason for the move, the child’s ties to the current community, the distance of the move, and the impact on the child’s relationship with the non-moving parent. In LaMusga v. LaMusga (2004), the California Supreme Court confirmed that the child’s best interests remain the overarching standard in relocation disputes.

Modification of Custody Orders

Either parent can request a modification of an existing custody order by demonstrating a significant change of circumstances since the last order. Common examples include a parent’s relocation, a change in the child’s needs, or a parent’s failure to comply with the existing order. The court applies the same best interests analysis when deciding whether to modify custody.

If the modification involves changing primary physical custody from one parent to the other, the requesting parent typically faces a higher burden of proof.

How Custody Is Determined: What to Expect

If you are heading into a custody dispute in California, the process generally follows these steps: the court orders mediation, both parents attend sessions with a mediator, and if mediation fails, the case moves to a hearing or trial. In some cases, the court may appoint a child custody evaluator under Family Code Section 3110 to conduct a thorough investigation and provide a report.

When to Seek Legal Help

California’s custody laws give judges wide discretion, which means outcomes can vary significantly depending on the facts and the judge. If your case involves domestic violence allegations, substance abuse concerns, relocation, or high conflict between parents, working with an experienced family law attorney is strongly recommended. Even in lower-conflict cases, understanding your rights under California law can make a meaningful difference in the outcome.

Frequently Asked Questions

Is there a presumption of joint custody in California?

Under Family Code Section 3080, there is a presumption that joint custody is in the child’s best interest only when both parents agree to it. When parents disagree, no presumption applies — the court evaluates the evidence independently. There is also a strong presumption under Family Code Section 3044 against awarding custody to a parent who has perpetrated domestic violence within the past five years.

Is mediation required in California custody cases?

Yes. Under Family Code Section 3170, California requires mediation before any contested custody or visitation hearing. The court refers the matter to a mediator through Family Court Services. In most counties, mediation is confidential and the mediator does not make recommendations, though some counties (including Los Angeles) allow mediator recommendations if the parties cannot agree.

At what age can a child express a custody preference in California?

Under Family Code Section 3042, the court must consider the wishes of a child who is mature enough to form an intelligent preference. Courts tend to give more weight to children roughly 14 and older, but there is no bright-line age. A judge may hear from younger children who demonstrate sufficient understanding.

What are the relocation notice requirements in California?

Under Family Code Section 3024, a custodial parent who wants to move a significant distance must provide 45 days’ written notice to the other parent. If the non-moving parent objects, the court holds a hearing evaluating the reason for the move, the child’s ties to the current community, and the impact on the child’s relationship with the non-moving parent.

What is Family Court Services and do I have to go?

Family Court Services (FCS) is a department within California Superior Courts staffed by licensed mental health professionals. Under Family Code Section 3170, participation is mandatory before any contested custody or visitation hearing. In recommending counties like Los Angeles and San Diego, the FCS counselor will make a recommendation to the judge if mediation fails. In non-recommending counties, the process is confidential and the mediator does not report to the court. Either way, attendance is required.

Can the FCS counselor’s recommendation be challenged?

Yes. If your county uses a recommending model, the FCS counselor’s recommendation is influential but not binding. You can present contrary evidence at a hearing or trial, call witnesses, and request a full custody evaluation under Family Code Section 3110 if you believe the FCS recommendation did not fully account for relevant circumstances. However, overcoming a negative FCS recommendation typically requires strong evidence.
