 Non-custodial parents who avoid their child support obligations are sometimes termed "deadbeat" parents.Parents who share an equal role in parenting are far more likely to comply, with child support compliance going up above 90% when the payer states she (or he) believes he has a relatively equal role in parenting.The US Department of Health and Human Services estimates that 68% of child support cases had arrears owed in 2003, a 15% increase from 53% in 1999.
