How to Establish Paternity in Nevada
Reviewed by DocDraft Legal Team · Nevada · Last updated 2026-09-12
In Nevada, establishing paternity means legally recognizing a child's father so the child can obtain support, custody and visitation, health coverage, inheritance, and benefits. Nevada has adopted the Uniform Parentage Act in Chapter 126 of the Nevada Revised Statutes. Unmarried parents who agree can sign a declaration for the voluntary acknowledgment of paternity developed by the State Board of Health; once signed it has the same effect as a court judgment (Nev. Rev. Stat. 126.053). Two Nevada rules are load-bearing. First, the marital presumption applies when a child is born during a marriage or within 285 days after it ends, a shorter window than most states, and it can be rebutted only by clear and convincing evidence (Nev. Rev. Stat. 126.051). Second, genetic testing that shows a probability of 99 percent or more creates a conclusive presumption of paternity, which can be rebutted only by proving the man has an identical sibling who may be the father (Nev. Rev. Stat. 126.051, 126.121). A court action to declare the father-child relationship is not barred until three years after the child reaches the age of majority, effectively the child's twenty-first birthday (Nev. Rev. Stat. 126.081). Attorney review of your situation is available through DocDraft.

Do I have to go to court to establish paternity in Nevada?
No, not if the parents agree. They can sign the declaration for the voluntary acknowledgment of paternity developed by the State Board of Health, which carries the effect of a judgment (Nev. Rev. Stat. 126.053). Court is required only when parents dispute parentage, and the judge can order genetic testing.
How long do I have to establish paternity in Nevada?
A court action to declare the existence or nonexistence of the father-child relationship is not barred until three years after the child reaches the age of majority (Nev. Rev. Stat. 126.081). Because majority in Nevada is 18, that effectively means the action can be brought until the child's twenty-first birthday.
What is the marital presumption of paternity in Nevada?
A man is presumed to be the father if he was married to the mother and the child was born during the marriage, or within 285 days after it ended (Nev. Rev. Stat. 126.051). That 285-day window is shorter than the 300 days many states use, and the presumption can be rebutted only by clear and convincing evidence.
What genetic-testing result establishes paternity in Nevada?
Under Nev. Rev. Stat. 126.051 and 126.121, genetic tests showing a probability of 99 percent or more create a conclusive presumption that the man is the natural father. That conclusive presumption can be rebutted only if he proves he has an identical sibling who may be the father.
Nevada paternity law at a glance
Nevada's Uniform Parentage Act (Nev. Rev. Stat. Chapter 126) lets unmarried parents establish paternity without court by signing a declaration for the voluntary acknowledgment of paternity developed by the State Board of Health, which carries the same effect as a court judgment (Nev. Rev. Stat. 126.053). A signatory may rescind within the earlier of sixty days or a related proceeding. Two rules make Nevada distinctive. The marital presumption reaches a child born during a marriage or within 285 days after it ends, a tighter window than the common 300 days, and yields only to clear and convincing evidence (Nev. Rev. Stat. 126.051). And genetic testing that reaches a 99 percent probability establishes a conclusive presumption of paternity, overcome only by proof of an identical sibling (Nev. Rev. Stat. 126.051, 126.121). A court action stays open until three years after the child reaches majority, roughly age 21 (Nev. Rev. Stat. 126.081).
Establishing Nevada paternity where a 99 percent test is conclusive
Suppose a child is born in Nevada to unmarried parents who agree. Both sign the declaration for the voluntary acknowledgment of paternity developed by the State Board of Health, which has the same effect as a court judgment (Nev. Rev. Stat. 126.053). Either may rescind within the earlier of sixty days or a related proceeding. Had the parents disputed parentage, either could file a court action, which is not barred until three years after the child turns 18, about age 21 (Nev. Rev. Stat. 126.081). The court could order genetic testing, and a probability of 99 percent or more would create a conclusive presumption of paternity, rebuttable only by proof of an identical sibling (Nev. Rev. Stat. 126.051, 126.121). Had the child been born within 285 days after a marriage ended, the former spouse would be presumed the father. Attorney review is available through DocDraft.

Suggested Compliance Checklist
Confirm whether the marital presumption applies
Before signing or filing anything days after startingDetermine whether the child was born during a marriage or within 285 days after it ended, which triggers Nevada's marital presumption (Nev. Rev. Stat. 126.051). That presumption can be rebutted only by clear and convincing evidence.
Get genetic testing if parentage is uncertain
Before signing the declaration days after startingBecause the declaration carries the force of a judgment, obtain genetic testing first if there is doubt. Under Nev. Rev. Stat. 126.051 and 126.121, a 99 percent probability creates a conclusive presumption of paternity that is very difficult to undo.
Sign and file the Declaration of Paternity

Frequently Asked Questions
Establishing paternity in Nevada means legally identifying a child's father so the child can receive support, custody and visitation, health coverage, inheritance, and benefits.

A court action to declare the existence or nonexistence of the father-child relationship is not barred until three years after the child reaches the age of majority (Nev. Rev. Stat. 126.081). Since majority is 18, the action can generally be brought until the child's twenty-first birthday.
A man married to the mother is presumed the father if the child was born during the marriage or within 285 days after it ended (Nev. Rev. Stat. 126.051).

Under Nev. Rev. Stat. 126.051 and 126.121, a probability of 99 percent or more from genetic testing creates a conclusive presumption of paternity.
