Primary physical custody in Nevada means one parent has the child for more than 60% of the year — roughly 219 or more overnights — while the other parent has the remainder as visitation. A Nevada court awards it when the evidence shows that a joint, roughly equal timeshare would not serve the child’s best interest. Everything else about the arrangement, from child support to where you can move, flows from that basic split.
The 60/40 Line That Defines Primary Custody
Nevada starts every case from a presumption of shared parenting. Under NRS 125C.0015, both parents automatically have joint legal and joint physical custody of their child until a court orders otherwise.1Nevada Legislature. Nevada Code 125C.0015 – Parents Have Joint Custody Until Otherwise Ordered by Court That presumption applies even to unmarried parents, so neither mother nor father begins with a built-in advantage.
The Nevada Supreme Court drew the line between joint and primary custody in Rivero v. Rivero (2009). Any schedule where each parent has at least 40% of the time counts as joint physical custody. Once one parent has the child more than 60% of the time, the arrangement is classified as primary physical custody with visitation for the other parent. That 40% floor corresponds to the 146-day figure built into the statute itself.
When a Court Will Award Primary Custody
NRS 125C.003 authorizes a court to award primary physical custody when joint custody is not in the child’s best interest.2Nevada Legislature. Nevada Code 125C.003 – Best Interests of Child: Primary Physical Custody; Presumptions; Child Born Out of Wedlock The statute names three situations where joint custody is presumed inappropriate:
- A parent cannot adequately care for the child for at least 146 days of the year (roughly 40% of the time).
- The child was born out of wedlock, paternity has not been legally established, and the father has not acknowledged or has abandoned the child. The reverse applies if the mother has abandoned the child and the father has been the sole caregiver.
- The court finds by clear and convincing evidence that a parent committed domestic violence against the child, the other parent, or anyone living in the household. That finding creates a rebuttable presumption against custody for the perpetrator.
Outside those presumptions, the court decides based on the best-interest factors in NRS 125C.0035, and it cannot favor one parent based on gender.3Nevada Legislature. Nevada Code 125C.0035 – Best Interests of Child: Joint Physical Custody; Preferences; Presumptions When Court Determines Parent or Person Seeking Custody is Perpetrator of Domestic Violence or Has Committed Act of Abduction Against Child or Any Other Child The judge must make written findings on:
- The child’s wishes, if the child is mature enough to express a meaningful opinion.
- Which parent is more likely to encourage a continuing relationship with the other parent.
- The level of conflict between the parents and their ability to co-parent.
- Each parent’s mental and physical health.
- The child’s physical, developmental, and emotional needs.
- The existing bond with each parent and who has historically handled day-to-day caregiving.
- The child’s relationships with siblings.
- Any history of abuse, neglect, domestic violence, or child abduction.
No single factor automatically wins the case. Income is not on the list, so a parent will not lose custody for earning less. Practical logistics often do the real work in contested cases. If one parent lives five minutes from the child’s school and the other lives an hour away, the judge may lean toward primary custody with the closer parent simply to keep the child’s weekday routine intact.
When domestic violence or child abduction is proven, the presumption against custody for that parent shifts the burden onto them to show that custody would still be appropriate. In practice, a documented history of violence often leads to a primary custody award for the other parent, sometimes paired with supervised visitation.
Legal Custody Is a Separate Question
Physical custody and legal custody are not the same thing, and the distinction matters. Physical custody governs where the child lives. Legal custody governs who makes major decisions about the child’s education, healthcare, religious upbringing, and extracurricular activities.4Nevada Legislature. Nevada Code 125C – Custody and Visitation
A court can award joint legal custody even when one parent has primary physical custody, and that combination is common. Under NRS 125C.002, there is a presumption in favor of joint legal custody when either parent has tried to maintain a meaningful relationship with the child. Losing on physical custody does not automatically mean losing a voice in school, medical, or religious decisions. The reverse is also true: having primary physical custody does not give you unilateral control over those decisions if the court has ordered joint legal custody.
What Primary Custody Changes for the Custodial Parent
Child Support
When one parent has primary physical custody, the other parent typically pays child support under Nevada’s statutory formula. NAC 425.140 sets the base obligation as a percentage of the noncustodial parent’s gross monthly income, with percentages that step down at higher income levels and rise with the number of children.5Nevada Legislature. Nevada Administrative Code Chapter 425 – Support of Dependent Children For one child, the formula starts at 16% of the first $6,000 of monthly gross income, then 8% on income between $6,000 and $10,000, then 4% above $10,000. The tiers scale up for additional children. For a low-income parent whose earnings fall below the schedule’s lowest level, NAC 425.145 allows the court to set a different amount based on the parent’s full economic picture.
The custodial parent manages those funds for the child’s benefit and is equally obligated to follow the visitation schedule the court ordered.
Relocation
Primary custody does not let you move the child wherever you want. Under NRS 125C.006, a primary custodian who wants to relocate outside Nevada, or to a distant part of the state that would interfere with the other parent’s relationship with the child, must first try to get the other parent’s written consent.6Nevada Legislature. Nevada Code 125C.006 – Consent Required From Noncustodial Parent to Relocate Child When Primary Physical Custody Established; Petition for Permission From Court; Attorneys Fees and Costs If the other parent refuses, you must petition the court for permission before moving. Relocating without consent or a court order can expose you to criminal liability under NRS 200.359.
If the case reaches a judge, NRS 125C.007 requires the relocating parent to show that the move is for a genuine, good-faith reason and not meant to cut off the other parent’s time, that it serves the child’s best interests, and that the child and relocating parent will gain a real advantage from the new location.7Nevada Legislature. Nevada Code 125C.007 – Petition for Permission to Relocate; Factors to Be Weighed by Court The court then weighs whether the other parent can realistically maintain meaningful visitation from the new distance.
Taxes
The parent the child lives with for more than half the year is generally the “custodial parent” for federal tax purposes. That status unlocks Head of Household filing, which carries a standard deduction of $24,150 for 2026 compared to $15,350 for single filers.8Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One Big Beautiful Bill The Child Tax Credit, worth up to $2,200 per qualifying child under 17 for 2026 with up to $1,700 refundable, also belongs to the custodial parent unless released to the other parent on IRS Form 8332.9Internal Revenue Service. About Form 8332, Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent Some divorce agreements require the custodial parent to sign Form 8332 as part of the settlement.
Filing for Primary Custody
The process begins with filing either a Petition to Establish Custody (for unmarried parents) or a Complaint for Divorce that includes custody requests (for married parents) in the district court. Filing fees vary by county. Your petition should include a detailed parenting plan that spells out the proposed schedule week by week, including holidays, school breaks, and summer.
After filing, the other parent must be formally served with a Summons and copy of the Petition by someone over 18 who is not a party to the case. The other parent then has 21 calendar days to file a response.10State of Nevada Self-Help Center. How to Respond to a Custody Complaint If no response is filed, the court may enter a default judgment based on your petition alone.
Many Nevada courts require parents to attend mediation before holding a contested custody hearing. If mediation does not resolve the dispute, the case moves to a judicial hearing where both sides present evidence and the judge applies the best-interest factors. The final order, usually called a Decree of Custody, binds both parents.
Changing a Primary Custody Order Later
Custody orders are not permanent. To modify one, you must prove two things: that a substantial change in circumstances has occurred since the last order, and that modifying custody is in the child’s best interest.11State of Nevada Self-Help Center. How to Change Custody, Child Support, or Relocate With a Child
Common triggers include a parent’s relocation, a significant change in work schedule, substance abuse, the child aging into different needs, or one parent consistently violating the existing order. You file a Motion to Modify Custody in the same district court that issued the original order, serve the other parent by mail, and submit a Request for Submission once the response period has passed. If child support is also at issue, attach a current Financial Disclosure Form with your three most recent pay stubs.
One boundary worth knowing: if you or the other parent is on active-duty military orders, the Servicemembers Civil Relief Act lets the deployed parent request an automatic 90-day stay of custody proceedings in writing, and the judge can extend it further. A military deployment also cannot be treated as abandonment or an inability to care for the child.
