Custody Evaluation Illinois: GAL, Child's Representative, and 604.10 Evaluations

Three Roles the Court Can Appoint

In contested Illinois custody cases, the court can appoint a professional to investigate, evaluate, or represent the child's interests. Under 750 ILCS 5/506, there are three distinct roles — and understanding the difference matters because each one operates under different rules about confidentiality, reporting, and whose interests they serve.

Guardian ad Litem (GAL)

The GAL acts as the court's independent fact-finder. Their job is to investigate the family situation and report back to the judge with recommendations.

What a GAL does:

• Interviews both parents, the child, teachers, therapists, and pediatricians
• May observe parent-child interactions
• Submits a written report with specific recommendations to the court and attorneys at least 30 days before the final hearing or trial
• Can be called as a witness and cross-examined by either parent's attorney

What a GAL doesn't have: an attorney-client relationship with the child. The GAL reports to the court, not the child. Anything the child tells the GAL can appear in the report. This distinction matters for older children who might share sensitive information.

Child's Representative (CR)

The CR advocates for the child's best interests but operates as a trial attorney rather than an investigator. The CR has the same investigative powers as a GAL but participates in the case differently:

• Files pleadings, examines witnesses, and makes legal arguments
• Does not file a written report and cannot be called as a witness
• Has a duty of confidentiality with the child — communications between the child and the CR are protected
• Considers the child's wishes but isn't bound by them; the CR advocates for what they believe is objectively best

The CR is common in cases with moderate complexity where the child needs an advocate in the courtroom but the court doesn't need a formal investigative report.

Attorney for the Child (AFC)

The AFC provides traditional legal representation to the child — the same undivided loyalty and zealous advocacy any adult client receives from their attorney. The AFC's job is to advocate for what the child wants, not what the AFC or the court thinks is best.

AFCs are typically appointed for older adolescents who can articulate clear, independent preferences. A 15-year-old who wants to live primarily with one parent would have the AFC argue for that position, even if the AFC personally thinks a different arrangement might be better.

Section 604.10 Evaluations

Separate from the three attorney roles, the court can order a professional custody evaluation under 750 ILCS 5/604.10. This brings in a mental health professional — usually a licensed clinical psychologist — to conduct a comprehensive evaluation of the family.

Court-appointed evaluator (604.10(b)): The court selects an independent evaluator who interviews both parents and the child, observes parent-child interactions, consults with teachers and therapists, and conducts psychological testing. The evaluator produces a detailed written report with recommendations that's automatically admitted into evidence unless a party objects.

Party's evaluator (604.10(c)): If you disagree with the court-appointed evaluator's conclusions, you can retain your own evaluator. You pay the full cost. The retaining attorney presents the 604.10(c) evaluator's findings as evidence at trial.

604.10 evaluations are distinct from standard clinical mental health evaluations. They focus on parenting capacity and co-parenting dynamics, not individual diagnoses. An evaluator might assess each parent's emotional regulation, ability to distinguish the child's needs from their own, and capacity to cooperate with the other parent.

What These Evaluations Cost

Costs vary widely, and they add up:

• GAL or CR fees: Fees vary with the professional and case complexity. The court allocates them between the parents based on income and assets, with itemized invoices reviewed every 90 days.
• 604.10 evaluations: Usually $5,000 to $15,000+ for a comprehensive evaluation, split between parents based on the court's allocation.

The financial burden is a serious consideration. In many cases, the cost of a GAL or evaluation exceeds the cost of reaching an agreement through mediation.

How to Navigate the Process

If a GAL or evaluator is appointed in your case, cooperation matters. Respond promptly to interview requests, provide documents when asked, and don't try to coach the child on what to say — evaluators are trained to detect scripted answers, and it backfires.

The Illinois Child Custody & Parenting Plan Guide includes a caretaking documentation log and evidence organization system designed to present your involvement clearly and factually to GALs, evaluators, and the court.
