Clinical psychologists and therapists are increasingly taking advantage of internet and mobile‐based technologies to deliver mental health services for individuals and groups since the COVID‐19 pandemic. However, there is a dearth of research evaluating the appropriateness of virtual platforms for family interventions. Further, no research has examined the effectiveness of weekly emotion‐focused family therapy (EFFT). This case study presents a virtually delivered 8‐week EFFT intervention, which supported caregivers to manage child symptoms of depression, anxiety, and anger, facilitate emotion processing, and strengthen relationships. Two parents from one family during a marital separation participated and completed brief measures of therapeutic alliance, family functioning, parental self‐efficacy, and parental and child psychological distress at 12 time points as well as a posttreatment semistructured interview. A strong therapeutic alliance was formed, and general family functioning, parental self‐efficacy, parent psychopathology, and child depression, anger, and anxiety symptoms improved over the course of therapy.
