DElay of time to receive, keeps CSED from unilateraly making increases in support without anyone imputting in for a modification(she or you have to do it) leaves CSED powerless without a court order to modify, and just gives more NCP's a feeling of meaning. For CSED to collect, she either has to be on some sort of assistance(state assistance) or she or you have to enter a application of aid for them to collect, for which they charge a processing fee, that either ways gets charged back to the NCP.
