Expert Witnesses and Evaluators

This guide is for informational purposes only and is not legal advice.

Your Situation

If your divorce or custody case involves a dispute about parenting — where your child lives, how decisions get made, or whether one parent poses a risk — the court may bring in a neutral professional to investigate and help it decide. In Colorado family (domestic relations) cases, that professional is usually a Child and Family Investigator (CFI) or a Parental Responsibilities Evaluator (PRE). A CFI investigates and reports on a narrower, court-defined set of questions; a PRE is a licensed mental health professional who conducts a deeper, often psychological, evaluation. The court can also appoint a Child Legal Representative (CLR) — an attorney who advocates for your child's best interests — and may receive written advice from other professionals.

This matters enormously because these experts carry real weight with the judge. Their reports and testimony can shape the parenting time schedule and decision-making responsibilities that govern your family for years. At the same time, their involvement adds cost, time, and a layer of scrutiny into your parenting. This guide will help you understand who these professionals are, how they're appointed, what they can and cannot do, how to work with them, and how to protect yourself if something goes wrong.

What the Law Requires

Colorado law lets the court appoint a neutral CFI in any case involving the allocation of parental responsibilities — on either party's motion or on the court's own initiative. The court's written appointment order spells out exactly what the CFI is authorized to investigate. A CFI must come from an official eligibility roster, must have independent perspective and appropriate training, and the court cannot appoint someone as a CFI unless it finds that person competent in domestic violence, coercive control, child abuse, and child sexual abuse. The same person cannot serve as both your child's legal representative and the CFI.

For a deeper mental health evaluation (a PRE), the court appoints or approves the evaluator, who must be a qualified licensed mental health professional selected from an eligibility roster. Before ordering a full evaluation, the court weighs whether a CFI investigation would be enough instead. If an evaluation touches an area outside the evaluator's expertise — such as substance abuse or psychological testing — the evaluator must consult a qualified specialist.

Several protections run in your favor:

• Disclosure of conflicts. Within seven days of appointment, a CFI, PRE, or child's legal representative must disclose any family, financial, or social relationship with you, the other party, the attorneys, the child, or the judge. You then have seven days to object based on that disclosure.
• Written disclosure of duties. Before doing any work, a CFI or evaluator must give you a written description of their specific duties, responsibilities, and limitations, plus how to file a complaint.
• The report doesn't control the outcome. The court must consider the entire report and any testimony before adopting any recommendation — it is not bound by what the CFI or evaluator suggests.
• Your right to cross-examine. You may call the evaluator (and anyone they consulted) for cross-examination at the hearing, and you cannot be made to waive that right before the hearing. A PRE's report must reach the court and all parties at least 21 days before the hearing, along with the underlying data.
• Limits on scope. A CFI cannot conduct psychological testing or order drug, alcohol, or polygraph testing unless the court specifically authorizes it, and cannot have private, off-the-record (ex parte) communication with the judge.
• Mandatory abuse reporting. A CFI must report child abuse to the proper agency and the court — this is non-discretionary.

💡

The court is required to weigh the full report and testimony before relying on any recommendation, so an expert's opinion is evidence the judge considers — not a verdict.

A quick but important distinction: a Guardian ad Litem (GAL) is not used in divorce/custody (domestic relations) cases — GALs appear in juvenile proceedings like dependency and neglect. In your divorce case, the attorney-for-the-child role is the Child Legal Representative, who files pleadings and advocates for the child's best interests but does not write a recommendation report and cannot be called to testify.

What Courts Typically Do

In practice, filing a motion to appoint a CFI does not guarantee one will be appointed — the court has discretion, and it often starts with the less intensive option (a CFI) before ordering a full psychological evaluation. When the court does appoint a CFI, the appointment order defines the scope, the fee split, and the report deadline, so courts expect you to read that order closely and stay within it.

Courts give real attention to whether the expert followed the rules. An evaluator's report is admissible only if the statutory procedural requirements are met — timely delivery, access to underlying data, and preserved cross-examination rights. In practice, judges weigh how reliable and well-supported the expert's conclusions are; for valuation and similar technical questions, how much weight an expert's method gets is left to the trial court's assessment of reliability.

Courts also pay close attention to cooperation. A CFI has explicit authority to report to the judge whether you cooperated — and in practice, uncooperative behavior ends up on the record and can count against you in parenting time and decision-making determinations. Where abuse is alleged, courts must consider admitting expert testimony from professionals experienced with abuse victims, even when that expertise isn't purely forensic.

Realistically, outcomes vary. A favorable report can strengthen your position, and an unfavorable one can hurt it — but because the judge weighs the whole record, neither is the final word.

Step by Step: What to Do

1. Confirm court authorization and request the right professional. To ask for a CFI, the court must first authorize the filing of your motion. The guided wizard on this site will prepare and pre-fill the motion to appoint a CFI, including the required authorization date, the reason for the request, and your proposed fee allocation — so you don't have to track down and complete the forms by hand.

2. Address cost up front. When you request a CFI, you'll propose how the fees should be split between the parties; the court makes the final call. If you can't afford your share, you can apply to have the state cover part of the cost based on indigency, determined by the parties' combined income and assets. The wizard can prepare the indigency application alongside your motion so the appointment isn't delayed.

3. Serve the other party. Your motion must be served on the other party, with proof of service filed. The wizard will handle this paperwork as part of the process.

4. Read the appointment order carefully. Once the court appoints the CFI, the order defines exactly what the CFI may investigate, the fee allocation, and deadlines. Know these boundaries — they protect you, and they tell you what's off-limits.

5. Review the appointee's disclosure. When the CFI, evaluator, or child's representative discloses their background and any relationships, read it closely. If it reveals a conflict, raise it with the court within seven days.

6. Make first contact promptly. You (or your attorney) must contact the CFI within 10 days of the appointment order to set up a first meeting. Don't let this slide — delay can be reported as non-cooperation.

7. Cooperate fully and completely. Confer with the CFI whenever and however they direct. Provide all court orders about parenting time or parental responsibilities issued after the appointment, disclose any related cases (protection orders, juvenile, criminal) when asked, and sign the releases the CFI needs.

8. Know the limits. A CFI cannot order psychological, drug, alcohol, or polygraph testing without a specific court order, and cannot make unsolicited referrals — if you want a referral, put the request in writing.

9. Prepare for the report and hearing. Expect a PRE's report at least 21 days before the hearing. Review it and the underlying data carefully, and preserve your right to cross-examine the evaluator and anyone they consulted.

10. If there's a problem, use the complaint process. If the CFI acts outside the appointment's scope, communicates privately with the judge, delays or writes a vague report, refuses to share their file, or commits another violation, you can file a formal complaint identifying each standard violated and explaining how. You can also challenge whether the expert is qualified to opine on specific issues — raising that before the final hearing preserves it for the court.

What Research Shows Can Help

The items here focus mostly on law and court practice rather than social science, so there is limited research-based guidance to offer on this specific topic. One research-informed point does appear in Colorado's own legislative findings worth knowing: when an alleged or known abusive parent claims the other parent is "alienating" the child, courts have been found to be roughly four times more likely to disbelieve a parent who reports physical or sexual abuse. If abuse is part of your case, be aware of how alienation claims and abuse allegations can interact, and make sure credible, well-documented evidence reaches the investigator and the court.

What to Do Today

• Start the guided wizard to begin preparing your motion for a CFI (and an indigency application if cost is a concern) so you're ready to file once the court authorizes it.
• Gather your documents — every court order about parenting time or parental responsibilities, and a list of any related protection order, juvenile, or criminal cases — so you can hand them over the moment a CFI is appointed.
• Calendar the deadlines you already know: the 10-day window to contact a CFI after appointment, and the 7-day window to object to a disclosed conflict.
• Write down your parenting concerns factually — dates, specifics, and what you observed — so your account to any investigator is concrete rather than general.
• If safety or abuse is a factor, start organizing any supporting evidence now, since courts must consider expert testimony from professionals experienced with abuse victims.

Related Issues to Be Aware Of

• Creating the parenting plan. Everything a CFI or evaluator investigates feeds into the best-interests analysis the court uses to allocate parenting time and decision-making, with the child's safety paramount. The factors they'll examine — your past involvement, the child's adjustment to home and school, each parent's values and commitment — are the same factors that will ultimately shape your plan.

• Substance use concerns. If drug or alcohol use is an issue, remember a CFI cannot order testing without a specific court order, and the evaluator may need to consult a substance-abuse specialist. After an abuse finding, the court can restrict a party from using alcohol or controlled substances during and in the 24 hours before parenting time.

• Mental health. A parent's or child's mental and physical health is a statutory best-interest factor, and the court can order evaluations to assess its impact — but a disability by itself cannot be used to deny or restrict parenting time. Watch for this if health is being raised against you.

• The child's voice in proceedings. A CFI's report must disclose the child's wishes if the child expresses them, which is one of the main ways your child's voice reaches the court without testifying. The court can also appoint a legal representative for the child or, on motion, interview the child in chambers.

• Parental alienation. If alienation is alleged, be especially careful: Colorado's legislative findings flag that abuse reports are more likely to be disbelieved when the other side claims alienation, and any court-ordered reunification treatment must rest on scientifically valid proof of its safety and effectiveness.
