How to Modify Child Support in Nevada
Reviewed by DocDraft Legal Team · Nevada · Last updated September 21, 2026
In Nevada, a child support modification is a court changing the amount of an existing support order after a parent's circumstances change, and the state gives you a clear signal for when to ask: a change of 20 percent or more in the gross monthly income of a parent who is subject to the order is deemed changed circumstances (NRS 125B.145). You can also ask a court to review the order at least every three years, even without that big a change (NRS 125B.145). Child support in Nevada follows a statewide guideline tied to income and the number of children (NRS 125B.080), so a raise, a job loss, or a new parenting arrangement can make the current amount too high or too low. You have two paths. You can file a motion to modify in the district court that issued your order, or, if the Nevada Child Support Enforcement Program under the Division of Welfare and Supportive Services (DWSS) manages your case, you can ask that agency to review it. A change reaches only support that has not already come due; installments that were already owed are a judgment that cannot be reduced retroactively (NRS 125B.140). Because of that, file as soon as your circumstances change rather than waiting, and keep paying your current order until a judge signs a new one.

How do I modify child support in Nevada?
File a motion to modify in the district court that issued your order, or ask the Nevada Child Support Enforcement Program to review it if that agency manages your case. You generally must show changed circumstances, and a 20 percent change in a parent's gross monthly income qualifies (NRS 125B.145).
How much does income have to change to modify child support in Nevada?
Nevada deems a change of 20 percent or more in the gross monthly income of a parent subject to the order to be changed circumstances that warrant a review for modification (NRS 125B.145). A smaller change can still qualify if you show it is substantial, but the 20 percent figure is the clear statutory trigger.
How far back can a child support change go in Nevada?
A modification reaches only installments that had not yet come due when a party gives notice that a motion to modify was filed (NRS 125B.140). Support that already became due is a judgment by law and cannot be reduced retroactively, so filing promptly protects you. Keep paying the current order meanwhile.
Which court handles child support modifications in Nevada?
The district court that issued your existing order handles modifications, since that court keeps jurisdiction over the case. If the Nevada Child Support Enforcement Program under the Division of Welfare and Supportive Services manages your case, you can also ask that agency to review the order and take it back to court if needed.
Nevada child support modification at a glance
In Nevada, a child support modification is a district court changing an existing support order after a parent's circumstances change. The state sets a clear trigger: a change of 20 percent or more in the gross monthly income of a parent subject to the order is deemed changed circumstances that warrant a review (NRS 125B.145), and you can also request a review at least every three years. Support follows a statewide guideline tied to income and the number of children (NRS 125B.080). You file a motion to modify in the district court that issued your order, or ask the Nevada Child Support Enforcement Program under DWSS to review it. A change reaches only installments not yet due when notice of the filed motion is given; support already owed cannot be reduced retroactively (NRS 125B.140).
Lowering a Nevada order after a 25 percent pay drop
Suppose your gross monthly income in Nevada dropped by 25 percent after a layoff, which clears the 20 percent change that Nevada deems changed circumstances (NRS 125B.145). You prepare a motion to modify child support, attach a financial disclosure of your lower income, and file it in the district court that issued your order. You serve the other parent and get a hearing date. Because a change reaches only installments not yet due when you give notice of the filed motion (NRS 125B.140), you file right away and keep paying the current amount until the judge rules. At the hearing the judge recalculates support under the guideline and signs a lower order. Attorney review of your filing is available through DocDraft.

Frequently Asked Questions
A genuine, involuntary income drop can support a modification, especially a fall of 20 percent or more in your gross monthly income (NRS 125B.145). You must still file a motion to modify; support keeps accruing at the old rate until a judge changes it (NRS 125B.140). Do not simply stop paying.
No. Either parent can file a motion to modify on their own in the district court, and the other parent is served and can respond. If both parents agree on a new amount, they can submit a written stipulation for the judge to approve, checked against the Nevada guideline (NRS 125B.080).
After you file your motion in district court, the court sets a hearing, often several weeks to a few months out depending on the county. An uncontested change or a Nevada Child Support Enforcement Program review can be faster. Because a change dates back only to notice of your filed motion, filing promptly protects you (NRS 125B.140).
Yes. If the Nevada Child Support Enforcement Program under the Division of Welfare and Supportive Services manages your case, you can ask it to review your order. The agency can pursue a modification through the district court when changed circumstances, such as a 20 percent income change, are shown (NRS 125B.145).
You can request a review at least every three years without showing a change, and sooner whenever changed circumstances occur (NRS 125B.145). A change of 20 percent or more in a parent's gross monthly income is deemed changed circumstances, so there is no need to wait when income shifts that much.
A modification changes support only going forward. Installments that already came due are a judgment by operation of law and cannot be retroactively modified or reduced (NRS 125B.140). Those arrears remain owed and continue to accrue interest, so keep paying your current order while your motion is pending.
Nevada has no single statewide numbered form for a support modification, so you file a motion to modify child support with the district court. The Nevada Self-Help Center, run by the Supreme Court, provides free forms, financial disclosure forms, and instructions, and some counties add their own local packets.
Yes. A modification can raise or lower support. A change of 20 percent or more in the paying parent's gross monthly income is deemed changed circumstances (NRS 125B.145), and you file a motion in district court so the judge can recalculate the amount under the state guideline (NRS 125B.080).
