In Nebraska, a signed and notarized acknowledgment of paternity can establish legal fatherhood, even when later DNA testing identifies a different biological father. Until recently, that could leave a biological father with limited ability to challenge an existing acknowledgment and seek legal recognition.
Effective April 15, 2026, Nebraska amended Neb. Rev. Stat. § 43-1409 to create a potential path for a biological father to challenge an existing acknowledgment using qualifying genetic evidence. The change does not automatically alter legal parentage. A court must still decide whether the legal requirements are met and what outcome serves the child’s interests.
Why the Nebraska Legislature Changed the Law
Before the amendment, Nebraska courts consistently emphasized the finality of voluntary acknowledgments of paternity.
Once an acknowledgment became effective, it generally could only be challenged by proving:
- fraud;
- duress; or
- a material mistake of fact.
However, this was generally limited to being brought by the father listed on the birth certificate. If the father on the birth certificate did not wish to be removed, there generally was not a method for the biological father to challenge the paternity finding.
Although DNA testing could prove biological fatherhood with extraordinary accuracy, Nebraska law generally did not allow the biological father to reopen the paternity issue.
As DNA technology became increasingly reliable, this legal framework created situations where biology and legal parentage did not align. The Legislature addressed that concern by amending Neb. Rev. Stat. § 43-1409 to expressly permit challenges by the biological father based upon accredited genetic testing.
What Does the New Law Allow?
Under the amended statute, a person may challenge an acknowledgment of paternity when accredited genetic testing establishes that:
- the acknowledged father is not the biological father; and
- the person filing the action is the child’s biological father.
Unlike prior law, reliable DNA evidence can now provide the legal basis for asking a Nebraska court to reconsider an existing acknowledgment of paternity.
Importantly, the amendment does not automatically change legal fatherhood. Instead, it gives the court authority to consider genetic evidence that previously could not independently support such a challenge.
What the New Law Does Not Do
- It does not automatically remove the acknowledged father from a birth certificate.
- It does not automatically establish the biological father as the child’s legal father.
- It does not make an at-home DNA test automatically admissible in court.
- It does not automatically end an existing child-support order.
- It does not guarantee a particular custody, parenting-time, or support outcome.
The Biological Father Must Be Seeking to Become the Legal Father
One of the Legislature’s most important safeguards is that the statute is generally intended to substitute one legal father for another—not simply eliminate an existing legal parent.
In most cases filed after April 15, 2026, the biological father must also seek to establish legal paternity in himself.
This reflects the Legislature’s effort to balance several competing interests:
- the child’s need for stability;
- the rights of biological fathers;
- the legal responsibilities associated with parenthood; and
- the state’s interest in ensuring children have legally responsible parents.
DNA Testing Must Meet Nebraska’s Legal Requirements
Not every DNA test will satisfy Nebraska law.
The statute requires scientifically reliable genetic testing performed by qualified laboratories that comply with Nebraska’s statutory requirements.
Home DNA kits or informal testing may not satisfy the evidentiary standards necessary for court proceedings.
An experienced family law attorney can determine whether existing testing is legally sufficient or whether additional testing should be obtained before filing a case.
What About Child Support?
One common misconception is that DNA testing automatically ends child support.
It does not.
Existing child support orders and legal obligations generally remain in effect unless and until the court orders otherwise.
No parent should stop paying court-ordered support simply because DNA testing has been completed.
Questions That Require Case-Specific Legal Advice
Because this amendment is new, court decisions will continue to clarify how it applies in different family circumstances. Cases may involve existing custody or parenting arrangements, the child’s relationship with a legal father, the type of genetic testing available, child-support orders, and procedural deadlines. A lawyer can review the facts and explain what the current law may allow in your situation.
What Should Biological Fathers Do?
If you have DNA test results establishing that you are a child’s biological father, the new law may provide legal rights that were previously unavailable. However, every case involves unique facts, filing deadlines, procedural rules, and evidentiary requirements. Prompt legal advice is important because waiting too long could affect your ability to pursue available remedies. You should speak with an attorney about whether you now have the ability to file a case and establish a legal relationship with your biological child.
Frequently Asked Questions
Can a DNA test overturn paternity in Nebraska?
Not automatically. Under the amended Neb. Rev. Stat. § 43-1409, qualifying DNA evidence may provide the legal basis to challenge an acknowledgment of paternity, but only a Nebraska court can determine whether the statutory requirements have been satisfied and whether it is in the minor child’s best interests to legally change paternity.
When did Nebraska’s new paternity law take effect?
The amendments became effective on April 15, 2026.
Can a biological father establish legal paternity?
Yes. The amended statute allows biological fathers, under qualifying circumstances, to seek both to challenge an existing acknowledgment of paternity and establish legal paternity in themselves.
Should I hire a lawyer?
Because these cases involve evolving law, strict procedural requirements, custody issues, and potential child support consequences, consulting an experienced Nebraska family law attorney is strongly recommended.
Why This Law Matters
Nebraska’s amendment to Neb. Rev. Stat. § 43-1409 recognizes what modern science has long established—that accredited DNA testing is an exceptionally reliable method of determining biological parentage.
By creating a legal mechanism for courts to consider that evidence, the Legislature has provided biological fathers with a new opportunity to establish a legal relationship with their child while preserving judicial oversight to protect the interests of children and families.
If you believe the new law may apply to your situation, obtaining legal advice early can help you understand your rights and determine the most appropriate course of action.
