In Nevada, SSDI (Social Security Disability Insurance) counts as gross monthly income for child support under NRS 125B.070 and Metz v. Metz, 120 Nev. 786 (2004), while SSI (Supplemental Security Income) is fully exempt under 42 U.S.C. § 407(a). A disabled obligor pays 16% on the first $6,000 of monthly income for one child. Support for a disabled child can continue indefinitely under Nev. Rev. Stat. § 125B.110.
Disability changes the arithmetic of Nevada child support in two directions: when a paying parent becomes disabled, and when a child's own disability extends the obligation past age 18. Both scenarios turn on which federal benefit is involved and on the tiered percentage guidelines that replaced Nevada's old flat-rate system in 2020. This guide explains how SSDI, SSI, derivative dependent benefits, and lifelong support for disabled children work under current Nevada law, with the specific dollar figures and statute sections courts actually apply.

How Does Disability Affect Child Support in Nevada?
Disability affects Nevada child support in two ways: SSDI benefits received by a paying parent count as income under the 16%/8%/4% tiered guidelines, while SSI is excluded entirely. Separately, a child's disability can extend support past age 18 indefinitely under Nev. Rev. Stat. § 125B.110. The distinction between SSDI and SSI is the single most important fact.
Nevada calculates child support as a percentage of the obligor's gross monthly income (GMI) under Nev. Rev. Stat. § 125B.070, with the detailed methodology in Nevada Administrative Code Chapter 425, effective February 1, 2020. When a parent's income shifts from wages to disability benefits, the court re-runs that percentage against the new income figure. For one child, the obligor pays 16% on the first $6,000 of GMI, 8% on income between $6,001 and $10,000, and 4% on income above $10,000. The 2020 reforms eliminated the former presumptive maximum cap of roughly $1,165 per child. Whether a disabled parent's payment goes up or down depends on how their benefit amount compares to their prior earnings.
Is SSDI Counted as Income for Child Support in Nevada?
Yes. SSDI is counted as gross monthly income for Nevada child support under Nev. Rev. Stat. § 125B.070 and the Nevada Supreme Court's decision in Metz v. Metz, 120 Nev. 786, 101 P.3d 779 (2004). A disabled parent receiving the 2026 national average SSDI benefit of about $1,580 per month would owe roughly $253 monthly for one child at the 16% tier.
The reasoning is federal. In Metz v. Metz, the Nevada Supreme Court held that Congress waived the anti-attachment exemption for Social Security Disability Insurance, so a district court may treat SSDI as income when setting a child support obligation. This aligns with the definition of gross monthly income in NAC Chapter 425, which lists Social Security disability benefits and old-age insurance benefits among countable income sources. Because SSDI is based on the disabled worker's own earnings record, the law treats it as a wage replacement rather than a needs-based grant. This is the core of the child support disability Nevada analysis: disability income child support obligations attach to SSDI just as they would to a paycheck. A disabled parent whose SSDI is their only income will still owe support calculated on that benefit.
Is SSI Exempt from Child Support in Nevada?
Yes. SSI (Supplemental Security Income) is fully exempt from Nevada child support under 42 U.S.C. § 407(a), as confirmed by Metz v. Metz, 120 Nev. 786 (2004). A Nevada court is prohibited from using SSI to set or enforce a support obligation because SSI is a needs-based grant, not earned-benefit income. SSI averages about $967 monthly in 2026.
The distinction matters because the two programs share a name but not a legal character. SSI provides a minimum income floor for people with little or no work history and limited resources. In Metz, the Nevada Supreme Court explained that forcing a parent to pay child support from SSI would do "major damage to a clear and substantial federal interest" — the guaranteed subsistence income Congress created. Under the Supremacy Clause, this federal exemption preempts Nevada's state child support statute. As a result, a disabled parent child support case built entirely on SSI produces a zero or nominal obligation, and SSI cannot be garnished. If a parent receives both SSI and SSDI, only the SSDI portion enters the disability income child support calculation.
What Is a Derivative SSDI Benefit and Does It Credit Against Support?
A derivative (dependent) SSDI benefit is a monthly payment the Social Security Administration pays directly to a child because a parent is disabled and drawing SSDI. Nevada courts generally credit these dependent benefits against the disabled parent's child support obligation, consistent with the offset principle recognized in Nevada authority such as Hern v. Erhardt, 113 Nev. 1330 (1997).
Here is how the SSDI child support math works in practice. When a parent qualifies for SSDI, each eligible minor child can receive a derivative benefit — typically up to 50% of the disabled parent's primary insurance amount — paid straight to the custodial household. Because that money already flows to the child on the disabled parent's earnings record, most courts treat it as satisfying the support obligation dollar-for-dollar up to the ordered amount. If the derivative benefit equals or exceeds the calculated obligation, the disabled parent may owe nothing further. If it falls short, the parent pays the difference. If the derivative benefit exceeds the obligation, the excess generally is not refunded to the parent but benefits the child. A disabled parent should promptly apply for these dependent benefits, because they can significantly reduce out-of-pocket support and, in some cases, offset arrearages that accrued during the disability determination waiting period.
SSDI vs. SSI: How Nevada Child Support Treats Each
SSDI is countable income and SSI is exempt — this table shows the practical differences that determine a disabled parent's Nevada child support obligation under Nev. Rev. Stat. § 125B.070 and Metz v. Metz. The single distinction between an earned-benefit program and a needs-based grant drives nearly every outcome for a disabled obligor.
| Feature | SSDI | SSI |
|---|---|---|
| Counts as income for support | Yes | No |
| Can be garnished for support | Yes | No |
| Based on | Worker's earnings record | Financial need |
| 2026 average monthly benefit | ~$1,580 | ~$967 |
| Derivative child benefit available | Yes (up to ~50%) | No |
| Governing authority | 42 U.S.C. § 407 waiver; Metz v. Metz | 42 U.S.C. § 407(a) exemption |
| Effect on obligation | Sets/continues support | Reduces to zero/nominal |
How Does Nevada Handle Child Support for a Disabled Child?
Nevada allows child support to continue indefinitely past age 18 for a child with a disability under Nev. Rev. Stat. § 125B.110, provided the handicap arose before the child reached the age of majority and renders the child unable to be self-supporting. Ordinary Nevada support otherwise ends at 18, or 19 if the child is still in high school.
This child support disabled child provision is one of the most consequential and least understood parts of Nevada law. Under Nev. Rev. Stat. § 125B.110, the obligation does not automatically terminate at the age of majority when a child has a qualifying disability. The statute requires that the handicap have occurred before the child turned 18, that it leave the child unable to be self-supporting, and that the child in fact not be self-supporting. When those conditions are met, a Nevada court can extend the support obligation for the child's lifetime, or until the disability resolves or the child becomes self-supporting. Courts weigh the child's own resources — including any SSI or other benefits the disabled child receives — alongside each parent's ability to pay. Parents raising a permanently disabled child should raise § 125B.110 explicitly in the divorce or support proceeding, because the extended obligation is not granted automatically and must be established while facts about the pre-majority onset are still provable.
Can You Modify Child Support After Becoming Disabled in Nevada?
Yes. Either parent may request a Nevada child support modification when there is a material change in circumstances, and Nev. Rev. Stat. § 125B.145 allows a review at least every three years. A change of 20% or more in gross monthly income is specifically defined as a changed circumstance, so a shift from wages to SSDI almost always qualifies.
Becoming disabled is a textbook basis for modification because it typically produces a large income swing. If a parent earning $6,000 monthly loses that job and begins receiving $1,580 in SSDI, the drop far exceeds the 20% threshold, and the disabled parent child support obligation should be recalculated against the lower figure. The modification is not automatic — the parent must file a motion with the district court that issued the order and provide documentation of the new income. Support does not adjust retroactively before the filing date, so a disabled parent should file promptly rather than assuming SSDI approval alone changes the order. Conversely, a custodial parent can seek an upward modification if the disabled parent's SSDI plus other income rises. Under Nev. Rev. Stat. § 125B.145, the court reviews the whole income picture, not just the disability benefit in isolation.
What Are the Filing Requirements and Costs in Nevada?
Nevada requires just six consecutive weeks (42 days) of residency before filing under Nev. Rev. Stat. § 125.020, one of the shortest residency requirements in the United States. Clark County charges approximately $364 to file a divorce complaint or about $328 for a joint petition as of June 2026 — verify current amounts with your local clerk.
To establish or modify child support tied to disability, you file in the district court of the Nevada county where a spouse resides or where the parties last cohabited, per Nev. Rev. Stat. § 125.020. The Eighth Judicial District Court handles Clark County (Las Vegas) matters through the eFileNV system, which adds a small per-document surcharge of about $3.50. Beyond filing fees, budget $50 to $125 for a process server if your spouse must be served, and roughly $174 for a responding spouse's answer. Fee waivers are available: Clark County grants an Application to Proceed In Forma Pauperis if household income falls below 150% of the federal poverty level ($22,590 for a single person in 2026), which is realistic for many disabled parents living on SSDI or SSI. A granted waiver eliminates filing fees for one year and permits free service by the county sheriff. Filing-fee figures change over time — confirm the current schedule with the district court clerk before filing.
