Ohio Custody Evaluation and Guardian Ad Litem: What to Expect

When Ohio Courts Order a Custody Evaluation

Not every Ohio custody case involves a custody evaluation. Courts typically reserve evaluations for high-conflict cases where parents can't agree on a parenting plan and the judge needs an independent expert assessment to make a best-interest determination under R.C. 3109.04.

A custody evaluation is a forensic assessment governed by Supreme Court Rule of Superintendence 91. The court appoints a licensed mental health professional — a psychologist, psychiatrist, or clinical counselor — to investigate each parent's home, interview both parents and the children, and submit a confidential report with custody and parenting-time recommendations.

The critical thing to understand: under Sup. R. 91, the evaluator is the court's expert. You cannot hire your own private custody evaluator to submit a competing report. If you disagree with the court-appointed evaluator's conclusions, your remedy is cross-examination at the final hearing.

What the Evaluator Actually Does

The evaluation process typically unfolds over several weeks and includes:

Individual parent interviews. The evaluator meets with each parent separately, usually for two to three hours. They'll ask about your parenting history, daily routines, discipline approaches, and your view of the other parent's involvement with the child.

Child interviews. The evaluator meets with each child, adjusting the approach based on age. For younger children, this often involves observing play. For older children and teenagers, the evaluator will ask about their relationships with each parent, their home environments, and their preferences.

Home visits. The evaluator visits each parent's residence to observe the living conditions, sleeping arrangements, and how the parent and child interact in a natural setting.

Psychological testing. Some evaluations include standardized psychological testing for one or both parents — typically instruments like the MMPI-2 or the Parenting Stress Index. This isn't automatic; the evaluator decides whether testing is warranted based on the case specifics.

Collateral contacts. The evaluator may interview teachers, pediatricians, therapists, coaches, or other people who observe the child regularly.

Under Sup. R. 91.07(A), the evaluator's final report must be submitted to the court, both parties, and the GAL at least 30 days before the final hearing. The report is admitted as the court's exhibit, and the evaluator can be subpoenaed for cross-examination by either parent's attorney.

How a Guardian Ad Litem Differs from a Custody Evaluator

Ohio courts often appoint both a GAL and a custody evaluator in complex cases, but they serve different functions.

A Guardian Ad Litem is an attorney or trained advocate appointed under Supreme Court Rule of Superintendence 48. The GAL's role is to investigate the child's circumstances and represent the child's best interests — not the child's stated preferences, and not either parent's position. GALs are trained investigators, not therapists.

The GAL typically conducts their own interviews, observes exchanges and parenting time, reviews school and medical records, and files a written recommendation with the court. Unlike the custody evaluator's clinical assessment, the GAL's report is a legal document that addresses whether the proposed custody arrangement serves the child's best interests under the R.C. 3109.04(F)(1) statutory factors.

In practice, a GAL's recommendation can carry significant weight with a judge, though neither the evaluator's nor the GAL's recommendation is binding.

What a Parenting Coordinator Does Post-Decree

If your case involves ongoing scheduling disputes after the decree, the court may appoint a Parenting Coordinator under Supreme Court Rule of Superintendence 90. Unlike the evaluator and GAL, who operate during the case, a parenting coordinator works after the decree is final.

The parenting coordinator has authority to make immediate, binding decisions on day-to-day scheduling conflicts — missed exchanges, holiday disputes, extracurricular scheduling. This avoids the cost and delay of filing a contempt motion every time a conflict arises. Either parent can request a review of the coordinator's decision by the court, but the coordinator's ruling stands until the court modifies it.

How to Prepare

Whether you're facing a custody evaluation, a GAL investigation, or both, preparation matters. Document your involvement in your child's daily life — school pickups, medical appointments, homework help, bedtime routines. Keep records organized, because the evaluator and GAL will both ask for specifics, not generalities.

The Ohio Child Custody & Parenting Plan Guide includes a best-interest factor worksheet that maps your parenting evidence to each of the R.C. 3109.04(F)(1) statutory factors — the same framework that evaluators and GALs use to structure their recommendations.
