Modification of an administrative order, procedure, effect

In plain English

After a child support order is made by the state division, the parent who owes support, the division, or the person caring for the child can ask to have the order changed. They file a written request explaining why it should change. The other side gets notified and has 30 days to respond. To get the amount changed, someone has to show that things have changed a lot and in a lasting way — not just a little. If the math using the court's standard rules would change the support amount by 20% or more, that counts as enough of a change to qualify. Only future payments can be changed, not ones already owed. A court can also let a parent off the hook from an order if it was entered by mistake or due to excusable neglect.
