In making custody determinations, a court’s only goal is evaluating and effectuating the child’s best interest. This Contribution argues that courts making child custody decisions must treat a parent’s sexual conduct with greater consistency and analytical rigor. Although the “best interests of the child” standard requires courts to weigh factors like parental fitness, stability, and capacity to provide care, the analysis of sex addiction within this framework remains fragmented and often distorted by moral judgment. This Contribution contends that sex addiction should only be considered by courts making custody determinations through a structured inquiry that distinguishes between diagnosis and conduct, resists moralistic reasoning, and requires a causal nexus between the conduct and potential or actual harm. By reframing courts’ consideration of sex addiction in custody determinations with regard to parenting capacity, courts will be better equipped to protect children’s welfare without encroaching on parents’ liberty.
