Child Support Modification - Nevada

NEVADA CHILD SUPPORT MODIFICATION

Official-Form Companion and Evidence Checklist

Do not file this document by itself. Use the current Nevada Supreme Court Motion to Modify Child Custody, Visitation, and/or Child Support, the current Financial Disclosure Form, the current Child Support Worksheet or calculator, and every required local form. This companion helps assemble and verify those filings.

1. Filing and Jurisdiction Gate

1.1 Existing order

NRS 125B.014 gives Nevada district courts jurisdiction over actions under Chapter 125B. The Nevada Self-Help Center directs a motion to change an order to the same district court where the case was filed. Confirm continuing authority, proper venue, and the exact local filing route before filing.

1.2 Interstate order screen

☐ The support order was issued by a Nevada court.

☐ The support order was issued outside Nevada or another state may retain continuing authority.

If the order was issued outside Nevada, stop and complete a Chapter 130 interstate-support analysis. NRS 125B.012 requires enforcement and modification of an out-of-state support order to comply with Chapter 130 when Chapter 125B is inconsistent with that interstate framework.

1.3 Local procedure profile

2. Statutory Review Ground

Select every ground supported by the current order and evidence.

☐ Three-year review request. At least three years have elapsed since the order was last reviewed. Under NRS 125B.145(1), a parent or legal guardian may file a separate request for review, and the court reviews the order at least every three years in response to such a request.

☐ Changed circumstances. The order should be reviewed before the three-year point because circumstances changed. Describe the change and when it occurred: [________________________________].

☐ Twenty-percent income change. A person's gross monthly income changed by 20% or more. NRS 125B.145(4) treats a 20% or greater change in the gross monthly income of a person subject to the order as changed circumstances requiring review. This is an income-change test, not a 20% difference between the old order and a new calculation.

☐ Custody or actual parenting arrangement changed. Identify the current order and the arrangement actually followed: [________________________________].

☐ A child reached an age or status requiring review. Identify the child and applicable NAC 425.160 route: [________________________________].

☐ Incarceration or involuntary institutionalization. Identify whether NAC 425.155 applies, including the 180-consecutive-day threshold and release date: [________________________________].

☐ Other change authorized by current law: [________________________________].

The court must still determine whether modification is appropriate, take the child's best interests into account under NRS 125B.145(2), and apply the current guidelines. The passage of three years or proof of a changed circumstance opens review; it does not prove a particular dollar result.

3. Required Official Packet

The current Nevada Self-Help Center identifies the following core documents for a request involving child support:

☐ Current Motion to Modify Child Custody, Visitation, and/or Child Support.

☐ Current Financial Disclosure Form.

☐ Three most recent paystubs attached to the Financial Disclosure Form, as directed by the current statewide self-help page.

☐ Current Child Support Worksheet or the current official calculator when the worksheet directs its use.

☐ Current support order and every later order affecting support or custody.

☐ Certificate of Mailing or other proof required by the current official instructions and local rules.

☐ Request for Submission or other local procedure used to place the matter before the judge after response and reply timing closes.

Additional case-specific attachments:

☐ Income records: tax returns, W-2/1099 forms, benefit statements, business records, or other records requested by the court.

☐ Child-care invoices and payment proof.

☐ Medical-support premiums, coverage, and unreimbursed-expense records.

☐ Custody / timeshare calendar and the order on which the existing calculation was based.

☐ Evidence supporting any requested deviation.

☐ Public-assistance notices or agency information.

☐ Other: [________________________________].

4. Caption and Party Information

Use the party designations from the existing case; do not switch “Plaintiff” and “Defendant” merely because a different party files this motion.

5. Current Order and Requested Change

5.1 Current terms

5.2 Requested terms

Do not ask this packet to erase arrears, impose enforcement sanctions, suspend a license, order contempt, or change custody unless the current motion, notice, evidence, jurisdiction, and governing procedure support that separate relief.

6. Guideline Calculation Record

NRS 125B.080 requires the court to apply the guidelines adopted under NRS 425.620 when determining or changing child support. The current operative guidelines are in NAC Chapter 425, not former NRS 125B.070.

6.1 Gross monthly income

NAC 425.025 controls included and excluded income. NAC 425.120 permits income to be determined by stipulation or by the court after considering relevant financial or earning-capacity information.

Do not copy taxable-income figures mechanically. Record overtime, self-employment, benefits, business income, and exclusions exactly as the current rule and evidence require. If imputed income is requested, address NAC 425.125 and the specific evidence bearing on good cause and earning capacity.

6.2 Custody adjustment and base obligation

☐ Primary physical custody calculation.

☐ Joint physical custody offset.

☐ Split or mixed custody calculation for multiple children.

NAC 425.115 controls the custody-based calculation. Use the current Nevada Supreme Court worksheet and NAC 425.140 schedule; do not reuse a former statutory percentage or an outdated worksheet.

6.3 Low-income schedule

☐ The current worksheet or calculator directs use of the low-income schedule.

NAC 425.145 requires the Administrative Office of the Courts to publish the low-income schedule annually. Attach or identify the current-year schedule used: [________________________________].

6.4 Child care, medical support, and deviations

• Reasonable child-care cost and proposed division under NAC 425.130: [________________________________].
• Medical-support provision required by NAC 425.135: [________________________________].
• Guideline amount before deviation: $[________].
• Requested deviation: $[________].
• Specific NAC 425.150 factor and supporting evidence: [________________________________].

If the proposed amount differs from the guideline result, identify the guideline amount and the facts supporting specific findings. NAC 425.100 requires findings explaining a deviation.

7. Public-Assistance and Agency Check

NRS 125B.065 requires the court, before modifying support, to determine whether any party receives or has ever received public assistance. If public assistance was received, the court must give the Division of Social Services notice and an opportunity to be heard before waiving arrears.

☐ The official motion's public-assistance questions are answered accurately.

☐ Any required agency notice or service is completed.

8. Facts Attachment

Use this as an attachment only if the official motion needs additional space.

1. The current support order was filed on [__/__/____] and requires [PARTY] to pay $[________] per month for [____] child(ren).
2. Review is requested under NRS 125B.145 because: [________________________________].
3. The change began on [__/__/____] and is supported by: [________________________________].
4. The current gross monthly income evidence shows: [________________________________].
5. The current custody arrangement and actual schedule are: [________________________________].
6. The current guideline calculation is attached and produces: [________________________________].
7. Child-care, medical-support, low-income, imputation, or deviation issues are: [________________________________].
8. The requested order is: [________________________________].

The declarant shall use the declaration and signature language in the current official motion. Do not add a notary block unless the current form or local rule requires one.

9. Filing, Service, and Submission Checklist

☐ File the completed official motion, Financial Disclosure Form, worksheet, and exhibits with the same district court where the case was filed, unless counsel confirms another lawful route.

☐ Pay the county-specific filing fee or file an approved fee-waiver application.

☐ Serve every filed document on the opposing party or counsel by the method stated in the current official instructions and local rules.

☐ File the required proof of service.

☐ Calendar the opposition and reply dates from the current motion and local rules; do not rely on a copied deadline.

☐ After response and reply timing closes, file the current Request for Submission or follow the district's current hearing-submission procedure.

☐ Obtain and review the signed order. A request does not change support; the existing order remains controlling until the court enters a new order.
