California Custody Evaluation: What to Expect and How to Prepare

When a California family court judge orders a custody evaluation under Family Code Section 3110, it means the court needs more information than mediation can provide. This is a forensic investigation of your family — and the evaluator's recommendation carries enormous weight.

Here is what happens during the process and how to approach it.

When Evaluations Are Ordered

A judge typically orders a custody evaluation in cases involving:

• Complex psychological dynamics — parental alienation allegations, personality disorders, or conflicting narratives that mediation could not resolve
• Safety concerns — domestic violence history, substance abuse, or mental health issues that require professional assessment
• Severe parental conflict — parents who cannot agree on any aspect of custody and whose CCRC session (in recommending counties) or mediation did not produce results
• Move-away disputes — one parent wants to relocate, and the court needs a professional assessment of how the move would affect the child

Evaluations are not routine. Most custody cases settle through mediation or CCRC without one. But when they happen, they are the most thorough — and expensive — tool the court has for understanding family dynamics.

Who Conducts the Evaluation

Under Family Code Section 3110, the court appoints a qualified evaluator who must be a licensed psychologist, psychiatrist, licensed clinical social worker, or marriage and family therapist with specialized training in:

• Child development and attachment
• Domestic violence screening
• Psychological testing
• Family systems assessment

The court may appoint a court-employed evaluator (through Family Court Services) or a private evaluator agreed upon by both parties. Private evaluators are more common in complex cases because they have more time to devote to the investigation.

What the Evaluation Involves

A comprehensive custody evaluation typically includes:

Psychological testing of both parents — standardized instruments measuring personality traits, parenting capacity, and psychological functioning. Common tools include the MMPI-2 (Minnesota Multiphasic Personality Inventory) and the PAI (Personality Assessment Inventory).

Parent interviews — multiple sessions, often totaling four to eight hours per parent. The evaluator asks about your childhood, your relationship history, your parenting approach, your co-parenting relationship, and your proposed custody arrangement.

Child interviews — the evaluator meets with each child individually, using age-appropriate techniques. Younger children may be observed in play therapy sessions. Older children may be asked about their preferences, routines, and feelings about each household.

Home visits — the evaluator visits each parent's home, observing the living environment, the child's room, safety conditions, and the parent-child interaction in a natural setting.

Collateral contacts — the evaluator interviews third parties including teachers, pediatricians, therapists, coaches, daycare providers, and other adults who interact regularly with the child. They may also review medical records, school reports, and law enforcement records.

Review of court records — the evaluator examines all prior filings, restraining orders, CCRC reports, and any previous custody orders.

Typical Timeline and Cost

Expect the process to take two to four months from appointment to final report. Some complex evaluations take longer.

Costs range from $1,000 to over $10,000, depending on whether the evaluator is court-employed or private, and on the complexity of the case. The cost is typically split between both parents, though the court may order a different allocation if one parent has significantly more resources.

Court-employed evaluators are generally less expensive but may have longer waiting lists and less time per case.

What the Report Contains

The evaluator produces a written report that includes:

• Clinical observations and psychological test results
• A summary of each parent's strengths and areas of concern
• An assessment of the child's needs, attachment patterns, and preferences
• A specific recommendation for legal and physical custody
• Recommendations for additional conditions (therapy, parenting classes, drug testing, supervised visitation)

This report goes to the judge, both attorneys (or both parties in pro se cases), and becomes part of the court record. Either parent can call the evaluator to testify at trial and cross-examine their findings.

How to Prepare

Be honest. Evaluators are trained to detect deception and exaggeration. Psychological testing includes validity scales that flag inconsistent or socially desirable responses. Getting caught being dishonest is far worse than disclosing unflattering truths.

Be child-focused in every interaction. When the evaluator asks about your co-parent, talk about the child. "I'm concerned about inconsistent bedtimes affecting her school performance" is more productive than "He's irresponsible."

Prepare your home. The home visit should show a safe, organized environment where your child has their own space. Have age-appropriate food, books, and activities visible. The evaluator notices whether the child has a bedroom, whether medications are stored safely, and whether the home is child-proofed for younger children.

Provide documentation proactively. Bring organized records of your involvement — school pickup logs, medical appointment history, extracurricular registrations, and communication records. A parent who shows up with a neatly organized folder signals preparation and engagement.

Follow all court orders. If you have a current custody order, follow it to the letter during the evaluation period. Any violation will appear in the report.

Do not coach your child. Evaluators are specifically trained to identify coached statements. A child who repeats scripted phrases or uses adult legal terminology raises immediate red flags.

After the Report

If the evaluator's recommendation does not support your position, you have options:

• File written objections to the report
• Request a hearing where the evaluator testifies and can be cross-examined
• Retain your own expert witness (a psychologist who can review the evaluator's methodology and findings)
• Present additional evidence the evaluator may not have considered
