This chapter focuses on the issue of shared physical custody (SPC) in the broader context of coparenting interventions. To identify if and how these interventions address the issue of SPC, we provide a systematic overview of the currently available types of coparenting interventions after marital dissolution. To be selected, the interventions had to be published in peer-reviewed journals, target separated or divorced parents, integrate work on coparenting, and include a custody focus within the intervention curriculum or as a targeted outcome. Finally, they had to be subject to empirical evaluation.As a second step, using a case study, we investigate how the issue of SPC may be addressed before divorce, during couple therapy. We describe the therapy sessions to highlight the factors that may protect or undermine the development of a cooperative coparenting relationship while separating, and eventually create a positive shared-custody scenario after divorce. We also analyse the couple’s progress regarding individual symptomatology and coparenting satisfaction based on self-reported questionnaires and on the quality of their observed coparenting interactions.From a therapeutic perspective, this chapter aims to deepen our understanding of the challenges and opportunities of coparenting during and after separation and its intertwinement with the issue of SPC.
