When non-custodial parents are ordered to pay child support, they are not being given the Federal Child Support Enforcement Handbook for Non-Custodial Parents. This handbook informs them of their rights to free legal representation to modify a support order, and about CSE grants to states for programs to enforce access rights to the children, without hiring an attorney. As a result, many fall into arrears in child support when they get laid off, because they think they need to hire an attorney. Further, they don't know what to do about being denied access to the children, without paying an attorney.
