When two people in Nevada decide to have a child, there is an expectation that they will support that child. If the parents subsequently divorce, one may gain custody of the children while the courts may order the non-custodial parent to pay a set amount of child support every month. Some parents are diligent about making their payments, but others neglect to send any financial support to their children.
There is no law against being legitimately unable to cover the support, and there are cases where the non-custodial parent is destitute and has nothing to send. On the other hand, there are parents who have the means to support their children but choose not to. When the evidence supports the idea that a person is willfully refusing to pay child support, then the criminal justice system may become involved in the case.
