This article outlines a new supervision practice of narrative therapy‐informed reflecting team‐based relational interviewing for a high‐conflict stuck case of a separated middle‐aged couple. The article demonstrates the supervision method consisting in five parts. First, the supervisor interviews the couples' relationship while the team watches from behind the one‐way mirror. Second, the team responds to the interview while the couple and the supervisor witness their conversation. The couple is then invited to respond back to the team. Furthermore, there is a meta‐conversation about the supervision in collaboration with the couple. The intervention ends with therapeutic letter writing to the relationship. The couple showed a meaningful shift in their positioning towards a more relational awareness and found valuable ways for continuing their therapy. The theoretical elements of the approach underpinning practice to tackle high conflict are considered through the illustration of the case.
