This document reviews empirical studies concerning the enforcement of the child support obligation and describes recent research on coparental interactions and father/child visitations. The discussion begins with an overview of the incidence of child support awards among demographically eligible women and then focuses on research on factors determining fathers' payment performance. Chambers' (1979) study of payment patterns of divorced males in Genessee County, Michigan is emphasized. Subsequently, attention is given to factors influencing post-divorce visitation arrangements, father involvement in parenting, and the relationship between child support payment and visitation. Major limitations of the studies are pointed out, and the need for research on the dynamic interface between child support payments and post-divorce spousal and father/child relationships is indicated.
