The integration of theories and techniques is part of family therapists’ daily practice, raising the need to understand which resources are used in this professional’s clinical actions. Our aim is to reflect on the use of theoretical and technical resources by family therapists in their daily practice. We developed an inquiry process inspired by collaborative action research and social constructionism. Couple and family therapy sessions were conducted by two family therapists, and we developed subsequent dialogs with them focused on describing theoretical and technical inspirations for their actions. Next, we named four categories of actions in this process: exploratory actions, actions for the construction of relational visions, actions for the construction of communication, and actions for family orientation. The therapists-participants referred to many theoretical and technical resources that inspired their practice. For them, the choice of using one or another resource was based on the demands of the interactive moment, which involves their relational and embodied responses to what was experienced in the sessions. We argue that epistemological coherence is not something that guides the therapist’s practice a priori, but something that can be achieved by talking about and reflecting on their actions. This article can contribute to clinical practice and training in family therapy by presenting an interesting reflexive process that can be useful to enhance practice in couple and family therapy (FAPESP, Process n. 2015/21316–1).
