Oregon Custody Evaluation: Process, Cost, and What Evaluators Look For

When mediation fails and the parents can't agree, the court may order a custody evaluation. This is one of the most intensive — and expensive — steps in an Oregon custody case. Understanding what happens during an evaluation helps you prepare effectively and avoid common mistakes.

When Courts Order Evaluations

Custody evaluations are not automatic. Under ORS 107.425, a judge orders one when the custody dispute is complex enough that the court needs expert input to make a best-interests determination. Common triggers:

• Both parents present credible but conflicting accounts of their parenting involvement
• Allegations of abuse, neglect, or substance abuse that require professional assessment
• Concerns about a parent's mental health and its impact on the child
• High-conflict cases where the judge needs an independent assessment of the family dynamic

Either parent can also request an evaluation, though the court decides whether to grant the request.

What the Evaluation Involves

A custody evaluation is conducted by a licensed mental health professional — typically a psychologist or clinical social worker with specialized family court training. The process is thorough and invasive:

Clinical interviews — Separate, in-depth interviews with each parent covering their parenting history, relationship with the child, daily routines, and their perspective on the custody dispute.

Child interviews — Age-appropriate conversations with the child (or children) to assess their emotional state, relationships with each parent, and any concerns. The evaluator is trained to distinguish between genuine statements and coached responses.

Home visits — The evaluator visits each parent's home to observe the living environment, the parent-child interaction, and the child's comfort level in each household.

Psychological testing — Standardized psychological assessments (personality inventories, parenting stress indices) that provide objective data alongside clinical observations.

Collateral contacts — Interviews with teachers, pediatricians, therapists, childcare providers, and other adults who regularly interact with the child and can speak to each parent's involvement.

Records review — School records, medical records, police reports, prior court orders, and any other documentation relevant to the custody determination.

Cost and Payment

Custody evaluations in Oregon typically cost several thousand dollars — fees ranging from $3,000 to $10,000 are common depending on the complexity of the case, the number of children, and the evaluator's rates. The court usually splits the cost between both parents, though a judge can assign a greater share to one parent based on financial circumstances.

If you can't afford a full private evaluation, some counties offer court-appointed evaluators at reduced rates. You can also request that the court consider the evaluation cost when making the final property division and support determinations.

Guardians ad Litem vs Custody Evaluators

Oregon courts can also appoint a Guardian ad Litem (GAL) under ORCP Rule 27. A GAL serves a different function than a custody evaluator:

Custody evaluator — Conducts a comprehensive psychological and behavioral assessment. Produces a detailed report with custody and parenting time recommendations. Functions as an expert witness.

Guardian ad Litem — Investigates the family situation and advocates for the child's objective best interests (not the child's subjective wishes). Conducts home visits, reviews records, and submits recommendations, but without the psychological testing component.

In some cases, the court appoints both. The evaluator provides the clinical data; the GAL provides the child-centered advocacy.

How to Prepare

Be honest. Evaluators are trained to detect inconsistencies, exaggeration, and rehearsed responses. A parent who presents a nuanced, honest picture of their strengths and weaknesses is more credible than one who portrays themselves as flawless.

Document your involvement. Bring evidence of your parenting — school records showing your name as a contact, medical appointments you've attended, emails or texts demonstrating cooperative co-parenting communication.

Keep your home evaluation-ready. This doesn't mean a magazine-perfect house. It means a clean, safe environment where the child has their own space, age-appropriate supplies, and visible signs of a stable routine.

Don't coach your child. Evaluators are specifically trained to detect coached responses, and getting caught coaching permanently damages your credibility. Let your child express their genuine feelings.

Cooperate fully. Refusing to participate in any part of the evaluation, delaying scheduling, or withholding requested documents signals to the evaluator — and the judge — that you have something to hide.
