Abstract
Child custody evaluations can have a significant impact on the adjustment and well-being of children and family members. Custody evaluators must be qualified and held to the highest professional standards. The authors of this article review custody evaluations and often witness inadequate and unprofessional evaluations. In this article, ethical mistakes seen regularly are highlighted. Many mistakes occur when cases are complex and include allegations of child maltreatment or intimate partner violence. Therefore, it is important that custody evaluators be trained in family and child psychology, attachment dynamics, psychological assessment, child abuse, and intimate partner violence. Child custody work needs to be monitored closely to ensure that mistakes can be eliminated in order to avoid unnecessary harm to children and families.
