California 3111 Evaluation: Process, Report, and Costs

A California 3111 evaluation is a court-ordered custody assessment in which a licensed mental health professional investigates both parents, observes the child, reviews records, and files a confidential written report with recommendations to the judge. It is authorized by Family Code 3111 and used when parents cannot agree on custody or visitation and the court decides an independent look at the family will help protect the child’s best interest.¹ The report carries real weight in how the judge decides where your child lives and how time is divided, so understanding the process before it starts matters.

When a Judge Orders a 3111 Evaluation

Evaluations are not automatic. A judge typically orders one when the custody dispute involves factual disagreements that testimony and paperwork alone cannot resolve: conflicting claims about parenting ability, allegations of abuse or neglect, or concerns about substance use. A full 3111 evaluation is broad. It covers where the child should live, how time should be divided, and how major decisions about the child’s life should be made.

If your case involves only a narrow issue, such as a scheduling dispute where primary custody is not in question, the court may order a more limited assessment under Family Code 3118 instead.² A limited assessment is faster and cheaper, but it does not produce the comprehensive custody recommendations that a full 3111 evaluation does.

Who Performs the Evaluation

California law restricts who can serve. Under Family Code 3110.5, the evaluator must be a licensed psychiatrist, psychologist, marriage and family therapist, clinical social worker, or professional clinical counselor qualified to assess couples and families.³ On top of the license, every evaluator must complete at least 40 hours of specialized training in child development, family dynamics, domestic violence, substance abuse, and child abuse before taking appointments, plus the domestic violence and child abuse training program required by Family Code 1816.⁴

If no qualified evaluator is available within a reasonable time, both parents can agree to use someone outside these categories, subject to court approval.

What the Evaluator Investigates

The investigation is anchored to the “best interest of the child” standard in Family Code 3011. The evaluator is looking at specific statutory factors:⁵

The child’s health, safety, and welfare in each parent’s care.
Any history of abuse by either parent against the child, the other parent, or other household members. The court can require independent corroboration, such as police reports or child protective services records.
The nature and amount of the child’s existing contact with each parent.
Habitual use of controlled substances or alcohol by either parent, which may also require independent corroboration.

Judges can direct the evaluator to look at issues specific to the case, and evaluators often form views on each parent’s ability to co-parent, maintain stability, and support the child’s relationship with the other parent.

What Happens During the Evaluation

The methodology is governed by California Rules of Court, Rule 5.220. Before substantive work begins, the evaluator gives you a written explanation of the evaluation’s purpose, procedures, expected timeline, scope of the final report, confidentiality limits, and who pays.⁶

Interviews and Home Visits

The evaluator interviews both parents, sometimes individually and sometimes together, to assess each parent’s understanding of the child’s needs, caregiving history, ability to set age-appropriate limits, and willingness to resolve the conflict. Joint interviews are generally avoided in domestic violence cases. The evaluator also has age-appropriate conversations and activities with the child, both alone and with each parent present, to see the relationships directly.

Home visits are standard. The evaluator watches how the child interacts with each parent on that parent’s own turf, paying attention to comfort, routine, and the physical suitability of the home. These observations carry weight because they capture dynamics interviews cannot.

Records and Collateral Contacts

Evaluators review school records, medical records, police reports, and any prior child protective services involvement. They may interview teachers, therapists, pediatricians, or others with relevant knowledge. If a topic falls outside the evaluator’s expertise, Rule 5.220 permits consulting other professionals.⁶

Psychological Testing

If testing is used, the evaluator must explain upfront what role the results will play, specifically whether they are being used to confirm or question other findings. Experienced evaluators rely on multiple data sources rather than a single test score.

How Long It Takes

Timelines vary by case and by county. A straightforward evaluation can finish in about two months. Cases involving domestic violence allegations, parental relocation, or a child who refuses to see a parent typically take six months or longer. Some counties set time limits on evaluators; others impose no formal deadline.

The biggest source of delay is often the parents themselves. Canceling appointments, dragging on document production, or making home visits difficult stretches the process out. The court usually cannot finalize permanent custody orders until the report is in, so delays hurt the child most of all.

The Report and When You Get It

The evaluator files the report with the court clerk and serves it on both parents (or their attorneys) and any attorney appointed to represent the child at least 10 days before the custody hearing.¹ That 10-day window is your time to read it, discuss it with your attorney, and prepare a response. The report must describe the evaluator’s data-gathering procedures, identify sources, disclose time spent, and present all relevant information, including findings that do not support the evaluator’s own conclusions.⁶

Confidentiality

The report is confidential and does not become part of the public court file. Only the parents, their attorneys, any attorney for the child, and certain court and child welfare professionals can see it.⁷ Anyone else needs a court order. Sharing the report with people who are not authorized — posting it online, giving it to extended family, handing it to a new partner — can result in monetary sanctions, including a fine large enough to deter future violations, plus the other side’s attorney’s fees and costs.¹

Using the Report as Evidence

The report can be received as evidence if all parties stipulate to it.¹ Otherwise, the evaluator generally has to testify and be subject to cross-examination before the report’s contents come in. Family Code 3117 requires the Judicial Council to adopt guidelines allowing cross-examination of court-appointed evaluators and requires written notice to both parties of their right to cross-examine.⁸

How Much the Report Influences the Judge

Judges are not required to follow the recommendations, but in practice these reports carry substantial weight. The evaluator is the only person in the case who has spent extensive time with both parents and the child, observed interactions in each home, and reviewed collateral records. No other witness at the hearing brings that depth.

Where the evaluator finds strong bonds and a stable home, courts tend to favor that parent for more custodial time. Findings of neglect, poor boundary-setting, untreated substance abuse, or an inability to support the child’s relationship with the other parent can reduce a parent’s custodial time or lead to supervised visitation. The report also shapes the mechanics of the order: pickup and drop-off logistics, holiday schedules, and whether transitions should happen in a neutral location.

The report is not the final word. If you believe the evaluator got something wrong, you can fight it at the hearing with testimony, documents, and cross-examination.

What It Costs and Who Pays

Custody evaluations are expensive. A full private evaluation in California commonly runs from a few thousand dollars to $10,000 or more, depending on the evaluator’s hourly rate and the case’s complexity. Abuse allegations, multiple children, and relocation disputes push costs higher because they demand more interviews and more collateral contacts. Court-connected evaluations through family court services may cost less, though availability and wait times vary by county.

The order appointing the evaluator specifies how the fee is split. Costs are often divided equally, but the court can order a different split if incomes are unequal or if one parent’s conduct drove the need for the evaluation. Rule 5.220 requires the evaluator to spell out cost and payment responsibility in the initial written disclosure.⁶

Your Rights During the Process

You get a written description of the evaluation’s purpose, procedures, scope, timeline, confidentiality limits, and cost before substantive work begins.⁶
You receive the completed report at least 10 days before the custody hearing.¹
You can call the evaluator as a witness and cross-examine them on methods, sources, and conclusions.⁸
The evaluator must observe and assess each parent using comparable methods; one parent should not receive significantly more or less scrutiny than the other.⁶

If the report contains errors or you suspect bias, cross-examination is the main tool for exposing the problem. Effective challenges focus on the reliability of the methodology, gaps in data collection, failures to corroborate key claims, and whether the conclusions actually follow from the evidence gathered. Your attorney can also present contradicting evidence, call rebuttal witnesses, and in some cases ask the court to appoint a different evaluator.

If You Refuse to Cooperate

Refusing to participate is one of the fastest ways to hurt your case. Rule 5.220 requires the evaluator to note any failure to cooperate in the report as a limitation on the evaluation’s completeness.⁶ Judges draw their own conclusions from that notation, and they are rarely favorable.

Cooperation means more than showing up. It includes providing accurate information, making documents available, allowing home visits, and facilitating the evaluator’s access to the child during your custodial time. Evasion tactics — canceling appointments, misleading answers, coaching the child — tend to backfire. Evaluators are trained to spot these patterns, and having them flagged in the report can be more damaging than whatever the parent was trying to hide.

3111 Evaluations Compared to 730 Evaluations

You may hear both terms in a California custody dispute. The names refer to different code sections, Family Code 3111 and Evidence Code 730, but both produce a custody evaluation report, and both evaluators must meet the same licensing and training requirements under Family Code 3110.5.³

The practical difference is mostly about who chooses the evaluator and who pays. A 3111 evaluation is typically handled by a court-connected evaluator on the court’s panel, with the cost structure set by the court order. A 730 evaluation generally involves a private evaluator selected by the court or agreed upon by the parties, and fees tend to be higher because private evaluators set their own rates. Some attorneys prefer 730 evaluations for more control over the choice of evaluator; others prefer 3111 evaluations to keep costs down. The methodology and standards the evaluator must follow are the same either way.⁶
