Medical Malpractice: Unanimous Decision Allows Therapist Lawsuit to Proceed

Texas Supreme Court revives malpractice lawsuit brought by detransitioner against therapist and clinic for harm allegedly caused during minor years.

On June 26, 2026, the Texas Supreme Court unanimously ruled to allow a malpractice lawsuit against a therapist and counseling group to proceed, overturning a lower court’s dismissal based on statute of limitations grounds. The decision marks a significant shift in how courts determine when the clock starts ticking on claims brought by minors who allege harm from medical interventions, particularly in cases involving therapists and clinics that provided gender-related medical care.

Soren Aldaco, the plaintiff in the case, is suing his former therapist and Three Oaks Counseling Group for over $1 million in damages, alleging that the defendants facilitated a botched double mastectomy procedure when Aldaco was a minor—a surgical outcome that has since become the basis for a detransition and substantial medical claims. This ruling is not merely a procedural victory; it establishes new legal precedent for how courts should handle the timing of medical malpractice claims when the injury occurs during childhood but the plaintiff does not recognize or pursue the claim until adulthood. The Texas Supreme Court’s unanimous decision signals that lower courts cannot simply dismiss such cases on technical grounds without examining the underlying facts and circumstances.

What Does This Texas Supreme Court Decision Mean for Therapist Malpractice Cases?

The Texas Supreme Court’s unanimous ruling addresses a fundamental question in medical malpractice law: when does a cause of action begin for a minor who claims harm from medical treatment provided by a therapist or physician? Previously, the lower court had dismissed Aldaco’s case entirely, arguing that too much time had passed since the procedure. The Supreme Court rejected this approach, recognizing that determining when a plaintiff discovers—or should have discovered—a malpractice claim is complex, particularly when minors are involved and the harm may not be immediately apparent.

This decision opens the door for other detransitioners and individuals who claim harm from medical interventions provided during their minor years. The ruling does not automatically mean Aldaco will win at trial, but rather that the case will proceed on its merits, allowing a jury to hear the evidence, examine the therapist’s actions, and decide whether negligence or malpractice occurred. For medical professionals and counseling groups, the decision means they can no longer rely solely on statute of limitations dismissals in cases involving minors and potentially controversial medical interventions.

Understanding the Statute of Limitations Challenge in Medical Malpractice Cases Involving Minors

The statute of limitations is designed to prevent plaintiffs from bringing claims years or decades after an alleged injury, when memories fade, evidence disappears, and defending against old claims becomes nearly impossible. However, medical malpractice law has long recognized an exception: when a plaintiff is a minor at the time of injury, courts often pause the statute of limitations until the minor reaches adulthood. The complication in Aldaco’s case involves determining the precise moment when the clock should have started—was it the date of the surgery, the date of detransition, or the date when Aldaco reasonably discovered that medical negligence had occurred? The lower court’s dismissal assumed a specific trigger date, while Aldaco’s legal team argued that the harm and its cause were not reasonably discoverable until much later.

This distinction is critical. Unlike a surgical error that causes immediate, obvious injury, the harm in gender-related medical cases may involve a combination of factors: the passage of time, changing personal perspective, and the psychological journey of detransition. A plaintiff might not associate previous medical decisions with malpractice until much later in life, when the consequences become clear. The Texas Supreme Court acknowledged this complexity and refused to allow an automatic dismissal, recognizing that statute of limitations questions in these cases require careful factual analysis, not blanket application of rigid timelines.

The Aldaco Case: A Detransitioner Seeks Accountability for Medical Harm

Soren Aldaco’s lawsuit centers on allegations of a botched double mastectomy procedure performed when Aldaco was a minor. The case involves both the individual therapist and Three Oaks Counseling Group, suggesting institutional involvement in facilitating or recommending the procedure. Over $1 million in damages is being sought, a figure that reflects claims of physical harm, psychological injury, and the long-term consequences of surgical intervention.

The specific allegations indicate that the defendants either performed medical procedures themselves or recommended and facilitated procedures that Aldaco now contends were improper, unnecessary, or negligently executed. Aldaco’s case is part of a broader movement among detransitioners—individuals who have transitioned and then later reversed that transition—seeking legal accountability from medical providers. These cases raise complex questions about informed consent, the duty of care owed to minors, and the appropriate standard of care for therapists working with gender-questioning adolescents. Unlike routine medical malpractice cases, these lawsuits often intersect with debates about the propriety of certain medical interventions for minors, making them particularly contentious and legally novel.

The Texas Supreme Court’s decision has immediate practical consequences for similar cases. First, it signals that courts must carefully examine the facts of each case rather than dismissing claims on statute of limitations grounds without a hearing. Second, it establishes that the discovery rule—the principle that the statute of limitations begins when a plaintiff discovers, or should have discovered, the injury and its cause—applies with particular force in cases involving minors and complex medical interventions. Third, it suggests that courts should hesitate before assuming that a plaintiff “should have discovered” malpractice at any particular moment, especially when the injury’s cause is not immediately obvious or when the plaintiff’s understanding of their own medical history evolves over time.

For defense attorneys representing medical providers, this ruling means that dismissal on statute of limitations grounds is no longer a reliable path out of litigation. Instead, defendants will need to prepare to defend the merits of their care and conduct. For plaintiffs’ attorneys, the decision validates the argument that cases involving minors and complex medical claims deserve a fuller hearing before being dismissed on technicalities. The ruling also has implications for settlement dynamics: defendants may be more willing to negotiate when dismissal is no longer a viable early-stage tactic.

The Growing Number of Detransitioner Lawsuits and Legal Accountability

The Aldaco case does not exist in a vacuum. In early 2026, Fox Varian, another detransitioner, won a $2 million settlement in New York—described as the first-of-its-kind settlement of its magnitude in this emerging area of law. That settlement demonstrated that courts and juries are willing to award substantial damages in detransitioner malpractice cases, at least in some jurisdictions.

The Varian settlement established a benchmark for compensation and validated the legal theory that medical providers owe duties of care to minor patients, even when the claim is brought years after the intervention. The Aldaco ruling in Texas and the Varian settlement in New York suggest that detransitioner litigation is becoming a significant area of medical malpractice law. More cases are likely to follow, particularly in states with favorable discovery rules or where courts are willing to look past statute of limitations defenses. These cases raise important questions about the standard of care for therapists and medical providers working with gender-questioning minors, the adequacy of informed consent, and the long-term consequences of medical interventions provided during vulnerable years of development.

What Happens Next: The Path to Trial and Potential Damages

With the Texas Supreme Court’s decision, Aldaco’s case will proceed to trial unless the parties reach a settlement. The next phase involves discovery, during which both sides will exchange evidence, depose witnesses, and build their cases. Aldaco’s legal team will need to prove that the therapist and Three Oaks Counseling Group breached the standard of care, that this breach caused injury, and that damages resulted. The defendants will present their own evidence regarding the care provided, the appropriateness of recommendations, and any complications that were unavoidable or unforeseeable.

The damages calculation in this case will be complex. Beyond the direct costs of the surgical procedure and any corrective surgeries, Aldaco will likely seek damages for pain and suffering, psychological harm, and the costs of reversing or managing the consequences of the initial procedure. The $1 million figure suggests substantial claims, though the actual award could be higher or lower depending on what a jury decides. Comparable cases, such as the Varian settlement, suggest that juries and settlement negotiators are willing to award significant compensation in detransitioner malpractice cases, particularly when harm to a minor is involved.

Why This Decision Matters for Patients and Medical Providers

The Texas Supreme Court’s unanimous decision sends a clear message: medical providers cannot rely on the passage of time to escape accountability for potential malpractice involving minors. For patients, particularly detransitioners who have had time to reflect on their medical history and current circumstances, the ruling opens a pathway to pursue legal claims that might otherwise have been barred by statute of limitations defenses. This is particularly significant because detransition—the process of returning to one’s previous gender identity—often involves both psychological and medical components that unfold over years, making it difficult for individuals to recognize and act on potential malpractice claims immediately.

For therapists, medical clinics, and healthcare institutions providing services to minors, the decision underscores the importance of careful documentation, rigorous informed consent processes, and adherence to appropriate standards of care. Medical providers who work with gender-questioning or gender-dysphoric youth should ensure that all recommendations are well-documented, that minors and their parents or guardians understand the implications of any proposed interventions, and that alternative approaches have been considered. The ruling does not necessarily mean that any particular medical intervention is improper, but it does mean that courts will scrutinize the care provided and that providers cannot assume they will escape liability based on technicalities or the mere passage of time.
