Information and communication technologies (ICT) have been gaining momentum in recent years. In the context of parental separation, these technologies represent privileged means for co-parents to communicate with each other on the organization of family life in shared custody, but also for parents to keep in touch with their children and maintain a relationship with them despite their absence. This article proposes a review of the literature on the use of ICT to communicate in the context of parental separation. Research findings are presented in four dimensions: 1) the different types of technologies used; 2) the influence of the quality of the co-parental relationship on communication; 3) perceived advantages; and 4) the perceived disadvantages of ICTs by the parents, children and professionals involved. Conclusions about the use of ICT in separated families are ambivalent, since the quality of the relationship between parent and child can be influenced positively and negatively by this type of communication. The shortage of scientific literature on this topic is an important limitation. Avenues for future research and recommendations for intervention are suggested.
