California 3111 Evaluation: Process, Cost, and Report

A California 3111 evaluation is a court-ordered custody investigation in which a licensed mental health professional interviews both parents, spends time with the child, visits each home, reviews records, and files a confidential written report recommending how custody and visitation should be arranged. Judges order these evaluations under Family Code 3111 when parents cannot agree and the court needs more than paperwork and hearing testimony to decide what serves the child’s best interest.¹ The report tends to carry real weight with the judge, so understanding how the process runs — and where your rights sit inside it — matters.

When a Judge Orders a 3111 Evaluation

A 3111 evaluation is not automatic. Courts reach for one when the custody dispute turns on factual questions that cannot be sorted out at a hearing: conflicting accounts of parenting ability, allegations of abuse or neglect, concerns about substance use, or a child whose relationship with one parent has broken down.

A full 3111 evaluation is broad. It covers where the child will live, how time is divided, and how major decisions about the child get made. If the dispute is narrower — for example, a scheduling disagreement where primary custody is settled — the court may order a more limited assessment under Family Code 3118 instead.² A limited assessment is faster and cheaper but will not produce comprehensive custody recommendations.

Who Does the Evaluation

California law requires that evaluators be licensed professionals: a psychiatrist, licensed psychologist, licensed marriage and family therapist, licensed clinical social worker, or licensed professional clinical counselor qualified to assess couples and families. Each must have completed at least 40 hours of specialized training in child development, family dynamics, domestic violence, substance abuse, and child abuse before taking appointments.³⁴ If no qualified evaluator is available within a reasonable time, both parents can agree to use someone outside those licensing categories, subject to the court’s approval.

What the Evaluator Looks At

The evaluation is anchored to the best-interest standard in Family Code 3011. Evaluators investigate specific statutory factors:⁵

The child’s health, safety, and welfare in each parent’s care.
Any history of abuse by either parent, whether directed at 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 or continual use of controlled substances or alcohol by either parent, which may also require independent corroboration.

Evaluators are not limited to these factors. A judge can direct the evaluator to look at additional issues specific to the case, and most evaluators form opinions about each parent’s ability to co-parent, maintain stability, and support the child’s bond with the other parent.

How the Process Actually Runs

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

Interviews and Home Visits

The evaluator interviews each parent, sometimes individually and sometimes jointly, assessing understanding of the child’s needs, caregiving history, ability to set age-appropriate limits, and willingness to work toward resolution. In cases involving domestic violence, joint interviews are generally avoided. The evaluator also meets with the child in age-appropriate ways, both alone and with each parent.

Home visits are standard. The evaluator watches how the child interacts with each parent in their own environment and takes stock of the physical home itself. These observations capture dynamics that interviews cannot.

Records and Collateral Contacts

Evaluators review school reports, medical records, police reports, and prior child protective services involvement. They may interview teachers, therapists, pediatricians, or others with relevant knowledge. If a topic falls outside the evaluator’s own expertise, Rule 5.220 allows consultation with other professionals. When psychological testing is used, the evaluator must explain upfront what role the test results will play — whether to confirm or question other findings.⁶

How Long It Takes

Timelines vary with complexity and county. A straightforward evaluation can finish in about two months. Cases involving domestic violence, parental relocation, or a child who refuses to see a parent typically run six months or more. Deadlines vary: some counties set formal time limits on evaluators, while others impose none.

Parents themselves are often the biggest source of delay. Cancelled appointments, slow document production, and difficulty scheduling home visits all stretch the process out. Permanent custody orders generally wait on the finished report, so the delay affects everyone involved, including the child.

What It Costs

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 require more interviews, more collateral contacts, and more time. Court-connected evaluations through family court services may cost less, but availability and wait times vary by county.

The appointment order spells out how the fee is split. Equal division between the parents is common. The court can order a different split if one parent earns significantly more 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

The Report and Who Can See It

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

The report is confidential. It does not become part of the public court file, and California law strictly limits who may see it: the parents, their attorneys, any attorney for the child, and certain court and child welfare professionals who need it to do their jobs.⁷ Anyone else needs a court order. Showing the report to extended family, posting it online, or handing it to a new partner can bring monetary sanctions large enough to deter future violations, plus the other side’s attorney’s fees and costs.¹

The report can come in as evidence if all parties stipulate. Without a stipulation, the evaluator usually needs to testify and be subject to cross-examination before the report’s contents are admitted. Family Code 3117 requires the Judicial Council to adopt guidelines allowing cross-examination of court-appointed evaluators and guarantees written notice of that right.⁸

How Much the Report Shapes the Judge’s Decision

Judges are not required to follow the evaluator’s recommendations, but these reports carry substantial influence in practice. The evaluator is the only person in the case who has spent extended one-on-one time with both parents and the child, observed them at home, and worked through the collateral records. No other witness replicates that depth during a hearing.

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

Still, the report is not destiny. If you believe the evaluator got something wrong, you can contest it. The report is one piece of evidence weighed alongside testimony, documents, and the judge’s own read on credibility.

Your Rights During the Evaluation

The process is designed to be thorough, but you have protections built in.

You receive a written explanation 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 hearing.¹
You can call the evaluator as a witness and question them about methods, data sources, and conclusions.⁸
The evaluator must observe and assess each parent using comparable methods, so one parent should not face significantly more or less scrutiny than the other.⁶

Cross-examination is the primary tool for exposing errors or bias. Effective challenges focus on methodology, gaps in data collection, failure to corroborate key claims, and whether the conclusions actually follow from the evidence. Your attorney can also present contradicting evidence, call rebuttal witnesses, or in some cases request appointment of a different evaluator.

What Happens If You Don’t Cooperate

Refusing to participate is one of the fastest ways to hurt your case. When a parent fails to cooperate, Rule 5.220 requires the evaluator to note that failure in the report as a limitation on its completeness.⁶ Judges draw their own conclusions from that notation, and they are rarely favorable to the non-cooperating parent.

Cooperation means more than showing up to interviews. It means providing accurate information, making documents available, allowing home visits, and facilitating access to the child during your custodial time. Cancelling appointments, giving misleading information, or coaching the child tends to backfire. Evaluators are trained to recognize those patterns, and a report flagging them can do more damage than whatever the parent was trying to hide.

3111 Evaluations and 730 Evaluations

In California custody disputes you may hear both “3111 evaluation” and “730 evaluation.” The names refer to different code sections — Family Code 3111 and Evidence Code 730 — but both produce a custody evaluation report for the court, and both evaluators must meet the same licensing and training requirements under Family Code 3110.5.³

The practical difference is mainly about who performs the evaluation and what it costs. A 3111 evaluation is typically conducted by a court-connected evaluator on the court’s panel, with the cost structure set by the appointment order. A 730 evaluation generally uses a private evaluator chosen by the court or agreed to by the parties, and fees tend to be higher because private evaluators set their own rates. The methodology and the standards the evaluator must follow are the same either way.⁶
