This paper focuses on what social scientists and policy analysts have learned about how child support, criminal justice, and reentry are related: How do child support obligations affect reintegration? How does incarceration affect child support repayment and debt? What policies exacerbate the debt-recidivism link? Which policies show promise in ameliorating it? These are complex questions largely because reentry from prison is itself a multifaceted process shaped by many institutional dynamics.
