Co‐therapy has been used widely in marriage and family therapy and counselling, especially in the second half of the last century. In recent years, there has been a decline in the use of co‐therapy, especially for financial reasons. However, currently, with the focus on dialogical ideas, co‐therapy has emerged as a preferable option. Although co‐therapy is now commonly used in dialogical practices, no clear description of the qualities of dialogical co‐therapy exist. Using practitioner research, we attempt to discover/describe specific qualities defining dialogical co‐therapy. The results show how a specific dialogical epistemology is evident in the co‐therapy setting and demonstrate the advantages and disadvantages of such a setting, as well as identifying the challenges co‐therapists working dialogically might face.
