At-Home Paternity Testing in West Virginia: The 98% Filing Rule and the Clear-and-Convincing Challenge Bar

There are no restrictions on at-home DNA testing in West Virginia. Any resident, from Charleston to Morgantown to the small towns along the Ohio River, can order a home paternity test kit and receive results without a court order, a lawyer, or an agency referral. Testing at home is a private decision. It stays between the people who took the test until someone chooses to share the results.

What makes West Virginia unusual is the way state law treats DNA evidence once paternity moves into a legal setting. Under W. Va. Code § 48-24-103, a blood or tissue test showing more than 98% probability of paternity, confirmed by additional testing, is treated as clear and convincing evidence. When results above that threshold go undisputed, they legally establish the man as the father for all purposes. That is a lower DNA bar than most states use to reach a conclusive finding. At the same time, once a father signs an acknowledgment and the 60-day rescission window closes, the standard to unwind it climbs to clear-and-convincing evidence of fraud, duress, or material mistake of fact — higher than the preponderance-of-the-evidence default most states apply. Lower bar to establish. Higher bar to unwind. That asymmetry matters.

Below: how West Virginia law defines paternity, how voluntary acknowledgment works, what happens if you want to challenge one, how court-ordered testing plays out, what the Bureau for Child Support Enforcement does, and where an at-home test fits in.

How West Virginia Law Defines Paternity

West Virginia's paternity statute lives in Chapter 48, Article 24 of the West Virginia Code. Unlike most states, West Virginia has not adopted any version of the Uniform Parentage Act. The state's paternity code is a stand-alone framework within the broader domestic-relations code, structured as a summary or equitable proceeding rather than the UPA template used across most of the country.

Under § 48-24-101, a paternity proceeding may be brought by the mother, the alleged father, the child, or the state through the Bureau for Child Support Enforcement. There is a statute of limitations in § 48-24-102: an action to establish paternity can generally be brought at any time until the child's 18th birthday. The child themselves may file on their own behalf up to age 21, giving adult children a short additional window to seek a determination.

West Virginia recognizes the common-law marital presumption. A child born to a married woman is presumed to be the child of her husband. There is an important procedural wrinkle written into § 48-24-101: a married woman is generally barred from filing a paternity action naming a man other than her husband unless the complaint alleges she was living separate and apart from her husband before the birth and did not cohabit with him during that separation. That threshold pleading requirement is one West Virginia-specific gate on marital-presumption cases.

Voluntary Acknowledgment of Paternity in West Virginia

Unmarried parents in West Virginia can establish legal paternity without going to court by signing an Affidavit of Paternity. The form is offered at the hospital shortly after the child's birth and can also be completed later through the Vital Registration Office.

• Form: West Virginia Affidavit of Paternity
• Filed with: State Registrar, Vital Registration Office (Health Statistics Center, WV Department of Health)
• Requirements: Signed by both parents, notarized, submitted with the birth registration or filed afterward
• Automatic transmission: A copy of a completed acknowledgment is forwarded to the Bureau for Child Support Enforcement (BCSE)
• Effect: Once filed and outside the rescission window, the acknowledgment establishes legal paternity with the same force as an adjudication

Because signing has the same legal weight as a court judgment, the moment before you sign is the moment to take testing seriously. If there is any doubt, an at-home paternity test gives you a private answer before a signature makes anything binding. You can order a home paternity test kit from US Diagnostics Center for $79, get results in about 7 to 10 business days from order to results, and make the decision with real information rather than assumption. At-home results are not admissible in West Virginia court, but they are for you — for the private question of whether to sign at all.

Rescinding or Challenging a Paternity Acknowledgment in West Virginia

Once a signature is on the affidavit and it has been filed, West Virginia gives signatories a short window to change their minds and a much harder path afterward.

The 60-Day Rescission Window

Under W. Va. Code § 16-5-10, either parent may rescind an acknowledgment of paternity within 60 days of execution, or by the date of an administrative or judicial proceeding relating to the child in which the signatory is a party, whichever comes first. That cutoff matters — a support proceeding, a custody hearing, or any similar action can close the rescission door before the 60 days run out.

Rescission during this window is procedural. You file the required form with the State Registrar and, if applicable, notify the other signatory. You do not need to prove fraud or mistake. This is the intended off-ramp for signatories who acted quickly and want to reconsider.

Challenge After the 60-Day Window

Once rescission closes, the standard changes sharply. West Virginia does not use the preponderance-of-the-evidence bar that most UPA states apply after rescission. Instead, a challenger must prove fraud, duress, or material mistake of fact by clear and convincing evidence. That is a heavier burden — the same standard applied in fraud cases generally — and it reflects a policy decision to treat filed acknowledgments as strongly binding once the initial window closes.

The practical result is that a signed acknowledgment in West Virginia is closer to a final judgment than in many other states. Genetic testing evidence still matters, but the challenger has to persuade the court that the original signature was tainted by fraud, coercion, or a serious factual misunderstanding — not merely that the tested man turned out not to be the biological father. The weight of that later burden is one reason people with real doubts test before they sign.

West Virginia's Paternity Adjudication Process

When paternity is not resolved by acknowledgment, West Virginia establishes it through a judicial proceeding. The action is filed in the circuit court or family court with jurisdiction over the child or the alleged father. Standing to file rests with the mother, the alleged father, the child, or the state through the Bureau for Child Support Enforcement when a child receives public assistance or when a parent applies for BCSE services.

The proceeding is framed as a summary or equitable action under Chapter 48, Article 24. The court can order genetic testing on request of any party or on its own motion. When results come in above the 98% threshold and are undisputed, the statute treats them as legally establishing paternity for all purposes when filed — meaning the court can enter a paternity finding without a full trial.

West Virginia also runs an administrative track through BCSE for cases already in the child-support system. In administrative proceedings, BCSE can order testing, obtain results, and use them to establish support orders. Contested cases move from the administrative track to family or circuit court.

Court-Ordered and Administrative Genetic Testing in West Virginia

Under § 48-24-103, court-ordered genetic testing is the backbone of contested paternity in West Virginia. The statute lays out three thresholds worth understanding:

• More than 98% probability, confirmed by additional testing: clear-and-convincing evidence of paternity. Undisputed results at this level legally establish the man as the father when filed.
• Below the 98% threshold: results remain admissible as evidence, but do not carry the same conclusive weight and are weighed alongside other evidence in the case.
• Exclusion: a properly conducted test that excludes the tested man is conclusive that he is not the biological father.

The 98% figure is notable. Many states set their conclusive statutory threshold at 99% or use CPI (combined paternity index) ratios of 100 to 1 or higher. West Virginia sets the bar slightly lower, which means state-approved testing can produce a legally dispositive result faster than in some peer states.

Genetic testing in West Virginia paternity cases must be performed by an accredited lab using an approved chain of custody. Home paternity tests do not meet those requirements. If a case reaches court, the parties should expect the court to order a fresh test at an accredited facility.

Refusing a court-ordered test carries consequences. Courts routinely treat refusal as evidence supporting the opposing party's position. For a broader look at what happens when a party refuses, see our article on what happens if you refuse a paternity test. For an overview of how the court process works, timelines, and cost, see the court-ordered paternity test process.

West Virginia Bureau for Child Support Enforcement

The Bureau for Child Support Enforcement (BCSE), housed within the West Virginia Department of Human Services, is the state agency responsible for administering the federal child-support program. BCSE gets involved automatically when a family receives public assistance and by application in cases where a parent seeks help establishing paternity or collecting support.

• Establishing paternity through voluntary acknowledgment or by referring contested cases to court
• Setting child-support orders using West Virginia's guidelines
• Enforcing orders through income withholding, license suspension, tax intercept, and lien authority
• Modifying orders when circumstances change
• Locating absent parents and administering interstate cases through UIFSA

BCSE routinely orders genetic testing early in a case to avoid establishing support against the wrong man. If you are on the receiving end of a BCSE letter asking you to submit to testing, do not ignore it — the administrative process moves without you. For a full explanation of how testing intersects with child support, see paternity testing for child support.

At-Home vs. Legal Paternity Testing in West Virginia

The two options exist for different purposes. An at-home test answers the biological question for the family. It uses the same laboratory analysis and the same genetic markers as a legal test, so the accuracy is the same. What differs is the chain of custody. At-home tests are self-collected and mailed back, which means they are not admissible in a West Virginia paternity proceeding.

A legal paternity test is court-admissible. Sample collection is supervised by a neutral third party, identities are verified with photo ID, and the chain of custody is documented from collection through analysis. Legal tests are appropriate when the result will be used in court, in a child-support proceeding, in a birth-record correction, or in an immigration matter.

Many families start with an at-home test to answer the question privately, then move to a legal test only if the result matters for a legal purpose. For a full comparison, see our article on home paternity test vs. legal paternity test. Note that US Diagnostics Center's legal paternity testing service is marked Coming Soon; the current at-home kit is designed for private, informational use.

How At-Home DNA Testing Works

The DNA testing process works the same way regardless of where you live:

1. Order your kit. You can order a home paternity test kit from US Diagnostics Center for $79. The kit ships to your West Virginia address and includes a prepaid return envelope for mailing your samples back.
2. Collect samples. The kit includes cheek swabs for the alleged father and the child. You rub the swab on the inside of each person's cheek for about 30 seconds. No blood, no needles, no pain.
3. Mail samples back. Seal the samples in the provided packaging and drop the prepaid envelope in the mail.
4. Lab analysis. Once the lab receives your samples, processing takes 2-3 business days. Our lab analyzes up to 28 genetic markers — well above the industry standard of 20 or more markers.
5. Get your results. Results are delivered securely online. You'll see either an inclusion (99.99% or greater probability of paternity) or an exclusion (0% probability).

The mother's sample is not required but can strengthen the analysis. A mother's kit can be added during checkout if you want to include it. Express result options are also available during checkout for faster turnaround.

Frequently Asked Questions

Can I use a home paternity test as evidence in West Virginia court?
No. At-home tests do not meet the chain-of-custody requirements for court admissibility. A West Virginia family court or circuit court considering a paternity question will order a fresh test at an accredited facility, typically through the Bureau for Child Support Enforcement or a court-approved lab. Home tests are for private use.

What is West Virginia's DNA threshold for legally establishing paternity?
Under § 48-24-103, a test result showing more than 98% probability of paternity, confirmed by additional testing, is treated as clear-and-convincing evidence. When such results go undisputed and are filed, the statute treats them as legally establishing the man as the father for all purposes. Results below the 98% threshold are admissible but do not carry the same conclusive weight, and are weighed alongside other evidence in the case.

How long do I have to rescind a Voluntary Acknowledgment of Paternity?
Sixty days from execution, or by the date of an administrative or judicial proceeding relating to the child in which the signatory is a party, whichever comes first. Because a support hearing can close the window early, act quickly if you have doubts.

What if I want to challenge an acknowledgment after 60 days?
You would need to prove fraud, duress, or material mistake of fact by clear and convincing evidence. That is a higher bar than most states use after rescission. Courts do not undo acknowledgments in West Virginia based on genetic evidence alone once the window closes — you have to show the signature itself was tainted.

Does West Virginia have a marital presumption?
Yes. A child born to a married woman is presumed to be the child of her husband. West Virginia adds a specific procedural hurdle: a married woman filing a paternity action against a man other than her husband must allege in the complaint that she lived separate and apart from her husband before the birth and did not cohabit during the separation.

Can the state force me to submit to genetic testing?
Yes, under a court order or a BCSE administrative order. Refusing generally leads to sanctions and can be treated by the court as evidence supporting the opposing party's case.
