A child’s treating therapist generally should not make custody recommendations. Whether a therapist can make custody recommendations at all comes down to a distinction courts and professional ethics codes take seriously: the person treating your child is not the person who is supposed to tell a judge which parent should have custody. That job belongs to a forensic custody evaluator appointed to assess the whole family. A treating therapist who crosses into that territory is stepping outside their role, and their opinion is vulnerable on both ethical and evidentiary grounds.
Why a Treating Therapist Shouldn’t Recommend Custody
Parents and attorneys routinely ask a child’s therapist for a letter supporting a particular custody outcome. The request sounds reasonable. The therapist knows the child, has spent months building trust, and presumably has insight worth sharing. But that is exactly the problem. A therapist whose job is to help a child heal cannot also be a neutral fact-finder for a judge without compromising one role or the other.
The American Psychological Association’s Ethics Code, Standard 3.05, tells psychologists to avoid multiple relationships that could reasonably impair their objectivity, competence, or effectiveness, or risk harm to the person they are treating. A therapist who has been working with a child for months has a therapeutic alliance with that child, limited or no exposure to the other parent, and a role as helper rather than investigator. Those are not neutral starting conditions for a custody opinion.
The APA’s Specialty Guidelines for Forensic Psychology are more specific. Guideline 4.02.01 warns that providing both forensic and therapeutic services to the same individual is a multiple relationship that can impair objectivity. Guideline 4.02.02 draws the practical line: testifying about a client’s diagnosis, treatment progress, and prognosis is acceptable clinical testimony, but offering opinions about custody arrangements or parenting quality crosses into forensic practice, which the therapist was not retained to do.
What a Treating Therapist Can Properly Say
Being called into a custody case doesn’t mean the therapist has nothing to offer. It means the therapist has to stay within the treating role. The safe scope of testimony includes:
- How many sessions have occurred and over what period.
- What problems the client presented with.
- What the treatment goals are.
- What progress has been made.
- Diagnosis, treatment plan, and prognosis.
What should not come from the treating therapist: opinions about which parent should have custody, whether a parent is fit, or what parenting-time arrangement serves the child’s best interests. Those opinions require assessment of both parents and the child together, which the treating therapist has not done.
Who Is Supposed to Make Custody Recommendations
Forensic custody evaluators are the professionals a court looks to for custody opinions. They are mental health professionals — psychologists, psychiatrists, licensed clinical social workers, or marriage and family therapists — appointed specifically to help the court understand a family’s dynamics. Unlike a treating therapist, a forensic evaluator has no prior relationship with either parent or the child. Their allegiance is to the court, not to any party.
Most evaluators are appointed by the judge, which reinforces the perception of neutrality. Some jurisdictions allow parents to retain a private evaluator, but a privately hired expert who has only assessed one household has an obvious credibility problem. Judges tend to give more weight to evaluators who have looked at the whole picture.
What the Evaluation Actually Involves
A thorough evaluation typically includes interviewing each parent individually, observing each parent interacting with the child, conducting age-appropriate interviews with the child, administering psychological testing, reviewing medical and school records, and interviewing collateral sources such as teachers, pediatricians, extended family members, and childcare providers.1American Psychological Association. Guidelines for Child Custody Evaluations in Family Law Proceedings Evaluators may also screen for substance use, domestic violence, and child maltreatment.
All of that gets synthesized into a written report that usually contains specific custody and parenting-time recommendations. The report goes into evidence and the evaluator may testify at trial.1American Psychological Association. Guidelines for Child Custody Evaluations in Family Law Proceedings Professional guidelines expect evaluators to actively question their own objectivity, watch for their own values and biases, and seek peer consultation when their impartiality is threatened.
The point isn’t that a forensic evaluator is smarter than a therapist. The point is that the evaluator has methodology, access to both parents, and a role designed for the question the court is asking. The treating therapist has none of those.
When a Child’s Statements Come Through the Therapist
Even when a therapist stays properly out of custody opinions, another problem often arises: someone wants the therapist to repeat what the child said in session. Those out-of-court statements are hearsay and are generally inadmissible unless an exception applies. The exception most often invoked in custody cases is Federal Rule of Evidence 803(4), which allows statements made for the purpose of medical diagnosis or treatment, including descriptions of symptoms, medical history, and their general cause.2Cornell Law Institute. Rule 803 – Exceptions to the Rule Against Hearsay
Courts applying this exception usually ask two questions: Did the child understand the statement was being made for treatment purposes, and was the statement reasonably related to diagnosis or treatment? A child who discloses abuse in a genuine treatment session, after the therapist has explained why truthfulness matters, has a stronger chance of having those statements admitted than a child interviewed in a setting that looked more like a legal investigation than a clinical appointment. If 803(4) doesn’t fit, a residual hearsay exception might still work, but it’s a harder argument.
Mandatory Reporting Sits Outside Confidentiality
One thing about therapist involvement in a custody case that surprises parents: the therapist’s duty to report suspected abuse doesn’t bend to the litigation. Every state has mandatory reporting laws that require mental health professionals — both treating therapists and forensic evaluators — to report suspected child abuse or neglect. The obligation stems from federal requirements under the Child Abuse Prevention and Treatment Act, which conditions state funding on maintaining mandatory reporting statutes.3GovInfo. Child Abuse Prevention and Treatment Act If a therapist has reason to suspect abuse, they must report it to child protective services regardless of what either parent or attorney would prefer. The specifics of who must report and under what circumstances vary by state.
Confidentiality also works differently once a court gets involved. In a court-ordered evaluation, there is no therapist-patient privilege shielding the findings. The report goes to the judge, and both parents and their attorneys will see it. Evaluators are expected to explain these limits at the outset so no one is caught off guard.1American Psychological Association. Guidelines for Child Custody Evaluations in Family Law Proceedings For particularly sensitive materials like raw test data, the evaluator can ask the court for a protective order limiting circulation beyond the proceedings.4American Psychological Association.

If a Therapist Has Already Written a Custody Letter
Suppose the other parent’s child therapist has already submitted a letter or is prepared to testify that your child should live primarily with the other parent. That opinion is not automatically discounted, but it is challengeable on the same grounds that made it problematic to give in the first place.
Cross-examination is the most direct tool. A treating therapist can be questioned about how much time they spent with each parent (usually little or none with the non-client parent), what assessment methodology they used to reach a custody opinion (usually none designed for that question), whether they administered validated instruments, and whether their conclusions actually follow from their clinical data. A therapist offering a custody opinion without having assessed the other parent is exposed on those points.
A parent can also retain their own expert to review the therapist’s letter or testimony and identify its methodological gaps. Competing expert input tends to be more persuasive when the rebuttal expert points to specific procedural failures rather than simply disagreeing with the conclusion. In some cases, the court may order a proper forensic evaluation to replace or supplement whatever the treating therapist has offered.
Judges are not bound by any single professional’s opinion. The judge weighs the totality of the evidence and gives more weight to clinical input that comes from someone qualified to give it, using methodology suited to the question. A treating therapist’s custody recommendation is often given little weight for exactly that reason. A forensic evaluator’s recommendation, grounded in assessment of everyone involved, usually carries considerably more. Neither one decides the case, but they do not sit on equal footing.
