A 730 evaluation is a court-ordered child custody evaluation by a mental health professional the judge appoints under Evidence Code section 730 to investigate and report on the child’s best interests in a contested custody case. The evaluator interviews the parents and child, gathers records, and writes a confidential report recommending a parenting plan; those findings often carry significant weight when the judge decides custody and visitation.

For parents and guardians in Orange County facing a custody dispute, it helps to know who performs the evaluation, how the process works, what happens when there are domestic violence or abuse allegations, how long it can take, what it can cost, how to prepare, how the report is used, how to challenge it, and how it differs from mediation.

What a 730 Evaluation Is

Family Code section 3111 lets the court appoint a child custody evaluator in a contested custody case when that serves the child’s best interests. Evidence Code section 730 lets the court appoint an expert to investigate, report and testify, on its own motion or at a party’s request.

Section 730 is a general rule of evidence, not a custody statute, so courts also use it to appoint experts outside family law. Evidence Code section 731, for example, addresses paying those experts in criminal actions and juvenile court proceedings.

Under the California Rules of Court, rule 5.220, a child custody evaluation is an expert investigation of the health, safety, welfare and best interests of the child. It can be full, or limited by court order in time or scope. The rule treats evaluation, investigation and assessment as the same thing, and each exists to assist the judge with disputed custody and visitation issues.

The California Courts self-help guide says judges order evaluations when they need more information, when a mediator recommends one, or when a parent asks. In high-conflict cases, an evaluation can look into concerns that declarations alone cannot resolve, such as a parent’s mental health or substance abuse; Family Code section 3011 lists habitual illegal drug use or alcohol abuse among the best-interest factors.

Who Can Be a Child Custody Evaluator

Family Code section 3110.5 generally limits the role to a psychiatrist, licensed psychologist, marriage and family therapist, clinical social worker, or professional clinical counselor, or a court-connected evaluator the court has certified. Each must complete domestic violence and child sexual abuse training. Before starting, the evaluator must declare under penalty of perjury that they meet all education, experience and training requirements and, if applicable, hold a license in good standing.

The evaluator may be a private professional or a court employee, but not your mediator. The court order defines the assignment, and the parties sometimes agree on an evaluator for the judge to appoint. Either way, these professionals answer to the court, not to either parent. The ethics rules in rule 5.220 require the evaluator to maintain objectivity, gather balanced information from both parties, control for bias, and disclose conflicts of interest.

What Happens During Child Custody Evaluations

Rule 5.220 requires the evaluator to give the parties a written explanation of the process: its purpose, procedures, timeline, confidentiality limits and costs. Both parents must be assessed in comparable ways.

Interviews are central. The evaluator may speak with each parent separately or together, interview the child in an age-appropriate way, and conduct observation of each parent with the child. The self-help guide says the evaluator may visit your home.

Collateral contacts follow. The evaluator may speak with the child’s teacher, daycare provider, doctors, a therapist, and other adults involved in the child’s life, including significant others who live in the home.

The evaluator may review school and medical records, police reports and court records. The evaluator may also require psychological testing of a parent. Psychological tests are one source among several, and the evaluator must explain whether the results confirm or question other information. For example, what teachers report can be checked against school records and each parent’s account.

Domestic Violence and Child Abuse Allegations

Rule 5.220 says joint interviews should not be held when domestic violence makes them inappropriate. You can request separate interviews and should give the evaluator any restraining orders.

When the court finds a serious allegation of child sexual abuse, Family Code section 3118 requires a more lengthy evaluation, including consultation with child welfare services and law enforcement. Child abuse allegations in other circumstances can trigger the same steps.

How Long It Takes and What It Costs

The self-help guide says an evaluation generally takes at least two months. The timeline depends on the issues the evaluator must investigate.

Costs vary. Parents usually pay, and the court allocates the fees. No statute sets a fee schedule; Evidence Code section 730 lets the court fix reasonable compensation.

For comparison, the Orange County court’s Family Court Services list estimates its Child Custody Investigation at $2,500 to $4,000, billed hourly with a $500 deposit, with the report typically 90 to 120 days after referral.

The Confidential Report

If the court directs a written report, it must be filed and served at least 10 days before the custody hearing. It goes into the confidential portion of the court file.

The report must summarize the evaluator’s findings and sources, including facts that do not support its conclusions, and note any limits such as a party’s failure to cooperate. A court can sanction a parent who shares the report recklessly or maliciously.

How to Prepare, and What Not to Do

The Judicial Council’s information sheet tells parents to follow the order on contacting the evaluator, sign record releases, cooperate fully, and send documents to the evaluator and the other parent at the same time.

Complete any intake forms on time. Bring organized, relevant documents. A calendar of your parenting time, school records and messages about the child help more than a stack of grievances.

Speak about your child’s needs and your plan to meet them. Show you support the child’s relationship with the other parent where it is safe. Family law attorneys often tell clients to present themselves honestly, including about their own weaknesses, because evaluators compare each account against other sources and candor helps credibility.

Do not coach your child or ask what they said afterward. Orange County’s Family Court Services gives parents the same instruction for child interviews, and rule 5.220 bars evaluators from pressuring children to state a preference.

Do not post about the evaluation, exaggerate allegations, or miss appointments.

How to Challenge a 730 Evaluation Report

An evaluator’s recommendations are not a court order. The judge may adopt, modify or decline them, and you may object and request a hearing to explain your concerns.

Under Evidence Code section 732, either party can call the evaluator to testify and conduct a cross examination. Your attorney may challenge whether the evaluation followed the California rules, since section 3111 says the court may consider an evaluation only if it meets the Judicial Council standards.

For concerns about how the evaluation was conducted, every court must have a complaint procedure under rule 5.220. Raise it promptly, and ask your lawyer whether a separate expert should review the evaluator’s methods.

730 Evaluations vs. Orange County Family Court Services

Some California counties use child custody recommending counseling under Family Code section 3183, where the mediator can recommend a custodial arrangement to the judge.

Orange County’s Family Court Services describes its mediation as confidential. If parents do not agree, the mediator does not make custody recommendations, though the mediator may recommend a 730 Evaluation or other services.

Family Court Services also offers a partial Child Custody Investigation. It is limited to up to four court-specified safety concerns and does not include a home visit. A private 730 evaluation can be broader. Our guide to a first custody hearing in Orange County explains where these services fit.

Frequently Asked Questions

What Is a Forensic Child Custody Evaluation?

It is another name for a court-ordered custody evaluation: an expert investigation prepared for the court, not therapy. The evaluator’s job is to gather facts and assess the child’s needs for the judge.

How Long Does a Court-Ordered Mental Health Evaluation Take?

A custody evaluation generally takes at least two months, according to the California Courts self-help guide. Child custody evaluations involving abuse allegations can take longer because of the added steps.

How to Win a Custody Modification Case?

Judges decide based on best interests under Family Code section 3011. An evaluator can be ordered to assess whether an existing order should change, so evidence about your child’s needs matters.

How to Impress a Judge in Family Court?

Follow every court order, be on time and prepared, and keep the focus on your child rather than on the other parent’s faults.
