By examining non-custodial fathers' relationships with their children and former spouses or partners and involvement with informal and formal networks, this study attempts to further the discussion on child support compliance among non-custodial fathers. Using data from the Fragile Families and Child Wellbeing Study, this study examines the influence non-custodial fathers' relationships and involvement with intra and extra-familial networks have in their achieving compliance toward their child support obligations including, establishment of paternity, establishment of child support orders, and timeliness of child support payments. Using logistic regression and linear regression, this analysis finds that non-custodial fathers' relationships with their former spouses or partners and involvement with formal networks contribute toward these fathers complying with their child support obligations. More specifically, non-custodial fathers' relationships with their former spouses or partners contribute to an increase in the establishment of paternity. Non-custodial fathers' involvement with formal institutions and organizations contributes to an increase in the establishment of child support orders. These results have implications for future research, policy, and programs that address non-custodial fathers and the child support enforcement system.
