Children's perspectives can enlighten decisions regarding custody and parenting plans, but different opinions exist about how best to involve children in the decision-making process. This article discusses why most procedures for soliciting children's preferences do not reliably elicit information on their best interests and do not give children a meaningful voice in decision making. Instead, these procedures provide children with forums in which to takes sides in their parents' disputes. In addition to hearing an individual child's voice, decision makers can use the collective voice of children, as revealed in research on such topics as joint custody, overnight stays, and relocation to help understand what children might say about these issues with the hindsight of maturity and in the absence of parental pressure, loyally conflicts, inhibitions, and limitations in perspective and articulation.
