730 Custody Evaluation in California — What It Is and What to Expect

A 730 evaluation — named after Evidence Code §730, which authorizes courts to appoint expert witnesses — is one of the most significant tools available in contested California custody cases. Also called a child custody evaluation under Family Code §3111, a 730 custody evaluation provides the court with an independent, professional assessment of the family dynamics and a recommendation for custody arrangements. Understanding what a 730 custody evaluation involves, how it is conducted, and how to present effectively is essential for any parent in a high-conflict custody proceeding.

What Is a 730 Custody Evaluation?

A 730 evaluation is an investigation conducted by a licensed mental health professional — typically a psychologist or licensed clinical social worker — appointed by the court under Evidence Code §730 and Family Code §3111. The evaluator is a neutral expert, not an advocate for either parent. Their role is to assess the family situation, identify each parent's strengths and limitations, evaluate the children's needs and relationships with each parent, and make specific custody and visitation recommendations to the court.

730 evaluations are ordered in contested custody cases where: the parents make materially conflicting claims about each other's parenting; there are allegations of domestic violence, child abuse, substance abuse, or mental health issues affecting parenting; parental alienation is alleged; the children's adjustment and wellbeing are significantly concerning; or the court finds it cannot make an informed custody decision without independent expert input.

How a 730 Custody Evaluation Works

The evaluation process typically takes three to six months and involves multiple components:

Parent interviews — Each parent is interviewed separately, often multiple times. The evaluator assesses each parent's understanding of the children's needs, their co-parenting relationship, their living situation, and their ability to support the children's relationship with the other parent.

Child interviews — The children are interviewed individually, in age-appropriate ways. Evaluators are trained to elicit genuine expressions of the child's experience rather than coached statements. For young children, play-based observation is used.

Joint observations — The evaluator may observe each parent interacting with the children in a naturalistic setting, assessing the quality of the attachment and the parent's attunement to the children's needs.

Collateral contacts — The evaluator interviews teachers, coaches, therapists, pediatricians, family members, and other people with direct knowledge of the family. These collateral contacts often provide some of the most objective information in the evaluation.

Record review — Medical records, school records, therapy notes, police reports, CPS records, and relevant court documents are reviewed.

Psychological testing — In some cases, particularly where mental health or substance abuse is at issue, the evaluator administers psychological tests to one or both parents.

The evaluator then prepares a written report with specific custody and visitation recommendations. This report is submitted to the court and provided to both parties. While the court is not bound by the evaluator's recommendations, these reports carry substantial weight — judges regularly follow them in full or in substantial part.

Who Pays for a 730 Evaluation?

730 evaluations are expensive — typically $5,000-$20,000 or more for a comprehensive evaluation. The court allocates the cost between the parties, typically proportional to their incomes under the same framework used for add-on child expenses. In cases where one party has significantly greater financial resources, the court may order that party to pay a larger share. Some evaluators offer reduced fees for lower-income parties; court-connected evaluations through some counties are less expensive than private evaluators.

How to Prepare for a 730 Evaluation

The most important principle in a 730 evaluation is authenticity. Evaluators are trained to identify parental coaching, scripted responses, and presentations that do not match the collateral information they receive. Parents who attempt to perform rather than present genuinely are typically identified by experienced evaluators — and this identification significantly damages their credibility.

Productive preparation includes: being specific and factual about your parenting history; being able to describe the children's needs, routines, school situations, and relationships in detail; being able to acknowledge the other parent's strengths rather than presenting all criticism; having records of your involvement (medical appointments, school events, activity participation) available; and following your attorney's guidance on what the evaluator will be assessing.

Using the 730 Report in Court

If you disagree with the evaluator's recommendations, you have the right to cross-examine the evaluator at hearing and to retain your own expert to critique the evaluation methodology. However, successfully challenging a 730 evaluation requires specific, substantive methodological critiques — not simply disagreeing with the conclusions. Courts are reluctant to disregard a thorough evaluation without compelling reason.
