Gatekeeping has been used as a theory and a measure to describe and assess family dynamics within the context of separation and divorce. In this article, we explore adaptive and maladaptive gatekeeping behaviors and attitudes that can affect the other parent's relationship with the child. Implications are presented for connecting adaptive and maladaptive gatekeeping responses to child outcomes of safety, well-being, and positive parent-child relationships following separation and divorce. We build on the recent attention to gatekeeping as a potential framework within the child custody context. Key Points for the Family Court Community: Gatekeeping is a useful framework for assessing parental behaviors and attitudes that can facilitate, protect, or restrict the involvement of the other parent with the child. Gatekeeping originally focused on maternal behaviors that facilitate or restrict the involvement of fathers with the children, Attention has shifted toward a more gender-neutral framework for assessing how parents' attitudes and actions affect the involvement and quality of the relationship between the other parent and child. Rather than a set of hardline rules that govern behaviors, gatekeeping requires working hypotheses to consider the various factors that may contribute to both adaptive and maladaptive gatekeeping responses.
