--- - |2 More than 22 million or 1 in 4 children in the United States are currently served by the child support program. This program, the third largest used to address childhood poverty, regulates non‐custodial parents' financial support of their children through federal, state, and municipal legislation and policies. The collateral consequences, particularly those related to economic stability and criminal justice involvement, associated with child support system participation have been widely studied. However, many of the interpersonal interactions between those who have cases in the system and those who work in the system have been largely ignored. In this article, I use courtroom observations, in‐depth interviews, and cultural artifacts to explore the practices of stigmatization and shaming in this important legal and bureaucratic process. I explore stigma and shame in three thematic areas: (1) shame in social interactions, (2) shame as a tool of social control, and (3) the social consequences of shame. I ultimately suggest that stigma and shame in the child support system, resembling that in the welfare and criminal justice systems, reinforces cognitive boundaries between parents perceived as “responsible” and those perceived as “deadbeats.” - 'Symbolic Interaction, EarlyView.
