The Effect of Joint-Child-Custody Legislation on the Child-Support Receipt of Single Mothers

Due to the preponderance of single mothers on public assistance, delinquent child support has been a contentious political issue in the U.S. We examine whether joint-child-custody reform affects the child-support receipt of single mothers. We use variation in the timing of joint-custody reforms across states to identify the effect of joint custody on the child-support receipt of single mothers. Joint-custody enactment raises the probability of receiving child support for all single mothers by 8%. The effect on all single mothers is driven by the effect on divorced mothers, as separated and never-married mothers are unaffected by joint-custody reform. We conclude joint-custody reform confers the most benefit on divorced mothers and their children, particularly those who do not receive public assistance.
