Quick answer: In Nevada, a support order must be reviewed by the court at least every 3 years on request, and can be reviewed at any time on changed circumstances. A change of 20% or more in a parent’s gross monthly income is deemed changed circumstances requiring a review. Past-due payments cannot be modified retroactively. Support is stated in monthly amounts.

What does this modification calculator check?
The calculator tells you whether Nevada’s review triggers are met (a 20% change in a parent’s gross monthly income, or 3 years since the order or last review), shows the monthly gap against the guideline amount and the accrued difference after notice. It cannot decide whether the court will modify the order, which it does taking the child’s best interests into account.
