At-Home Paternity Testing in Mississippi: One-Year Rescission Window and Disestablishment Rights

Mississippi has no restrictions on at-home paternity testing. You can order a kit, collect DNA samples at home, and mail them to a lab without any state-level barriers. If you want a private answer about biological paternity, any Mississippi resident can do it.

What makes Mississippi's paternity laws distinctive is a combination of features you will not find in most other states. Mississippi gives signatories a full one year to rescind a voluntary acknowledgment of paternity — far longer than the 60-day federal minimum most states follow. The state also has a specific disestablishment of paternity statute (Miss. Code Ann. 93-9-10) that gives legal fathers a defined path to undo a paternity finding based on newly discovered DNA evidence. And Mississippi is one of the few states that explicitly prohibits jury trials in paternity proceedings. These rules create a framework worth understanding before you sign anything or head to court.

Below: how Mississippi defines paternity under the Uniform Law on Paternity, the voluntary acknowledgment process, disestablishment rights, and where at-home DNA testing fits in.

How Mississippi Law Defines Paternity

Mississippi paternity law is governed by the Uniform Law on Paternity, found in Mississippi Code Title 93, Chapter 9, beginning at Miss. Code Ann. 93-9-1. The statute covers who can bring a paternity action, genetic testing requirements, voluntary acknowledgment procedures, and the disestablishment process.

Marital presumption: Mississippi follows the common law presumption that a child born to a married woman is the child of the husband. The husband is automatically treated as the legal father, his name appears on the birth certificate, and he has full parental rights and obligations from birth. This presumption is rebuttable, but overcoming it requires evidence — typically DNA testing.

Who can bring a paternity action: Under Miss. Code Ann. 93-9-9, paternity may be determined upon the petition of the mother, the father, the child, or any public authority chargeable by law with the support of the child. This includes the Mississippi Department of Human Services when public assistance is involved.

No jury trial: Mississippi is one of the states that explicitly bars jury trials in paternity proceedings. Under Miss. Code Ann. 93-9-27, parties to an action to establish paternity are not entitled to a jury trial. The judge alone decides the case. This means DNA evidence and testimony are weighed by a single decision-maker rather than a panel of jurors.

Paternity can be established until age 21: Mississippi law authorizes paternity establishment at any time until the child turns 21 years old or until the child is emancipated, whichever comes first.

Voluntary Acknowledgment of Paternity in Mississippi

For unmarried parents who agree on who the father is, Mississippi offers a voluntary acknowledgment of paternity, known as A Simple Acknowledgment of Paternity (ASAP). This is the simplest way to establish legal fatherhood without going to court.

Under Miss. Code Ann. 93-9-28, both parents can complete the ASAP form at the hospital when the child is born. Hospital staff provide the forms and explain the legal consequences. The signed acknowledgment is filed with the birth certificate through the Mississippi State Department of Health, Vital Records.

Key details about Mississippi's voluntary acknowledgment:

• Both parents must sign voluntarily. The signatures of both the mother and father must be notarized. Neither parent can be pressured or coerced.
• The form can be completed at the hospital or later. If parents did not sign at birth, they can complete the ASAP afterward through Vital Records.
• Once properly completed, it constitutes a full determination of legal parentage. The statute is explicit: when the form has been completed according to established procedure and both signatures are notarized, the voluntary acknowledgment constitutes a full determination of the legal parentage of the child. It has the same legal effect as if the mother and father had been married at the time of birth.
• The father's name is added to the birth certificate. Filing the ASAP amends the child's birth record.

If you are unsure whether you should sign, consider getting a private answer first. A home paternity test costs $79 and gives you results in days. Those results will not hold up in court, but they can help you make an informed decision before putting your name on a legal document that becomes very difficult to undo.

Rescinding or Challenging a Paternity Acknowledgment

What if someone signs an ASAP and later questions whether the biological information is correct? Mississippi provides one of the longest rescission windows in the country.

The One-Year Rescission Period

Under Miss. Code Ann. 93-9-28, any signatory to a voluntary acknowledgment of paternity may rescind the acknowledgment within the earlier of one year from signing or the date of a judicial proceeding relating to the child in which the signatory is a party. Most states follow the 60-day federal minimum. Mississippi gives you a full year. That is a significant difference for anyone who signed under uncertainty.

Genetic testing during the one-year window: The ASAP form itself tells the alleged father about his right to request genetic testing through the Mississippi Department of Human Services during the one-year period. The form also warns about the consequences of not taking advantage of this one-time opportunity to definitively establish biological paternity.

Tolling provision: Mississippi includes a tolling provision that pauses the one-year clock. Under Miss. Code Ann. 93-9-9, if the alleged father files a formal application for genetic testing with the Department of Human Services, the one-year period is tolled — paused — from the date of application until the date the test results are revealed to the alleged father. This prevents the clock from running out while someone is actively pursuing DNA testing.

Challenge After One Year

Once the one-year window closes, the only way to challenge a paternity acknowledgment in Mississippi is through the courts. The challenger must demonstrate fraud, duress, or material mistake of fact, with the burden of proof on the person bringing the challenge. DNA test results showing the man is not the biological father would typically qualify as evidence of a material mistake of fact, but the standard is harder to meet after the rescission period expires.

Because Mississippi gives you a full year, there is time to get a private answer. For $79, a home paternity test gives you an accurate biological answer that can inform your decision about whether to rescind before the window closes.

Mississippi's Paternity Establishment Process

When paternity cannot be resolved through a voluntary acknowledgment, Mississippi provides a court process to establish it.

Under Miss. Code Ann. 93-9-9, the following parties can file a paternity petition:

• The child's mother
• The alleged father
• The child
• Any public authority chargeable by law with the support of the child (typically the Mississippi Department of Human Services)

The court process involves filing a petition, serving the other parties, and proceeding to a hearing. As noted above, Mississippi does not allow jury trials in paternity cases — the judge alone makes the determination based on the evidence presented.

Disestablishment of paternity: Mississippi is one of the states with a specific disestablishment statute. Under Miss. Code Ann. 93-9-10, a legal father who has been ordered to pay child support can petition the court to disestablish paternity if he has newly discovered evidence — specifically, DNA test results administered within one year before filing the petition — showing he is excluded as the biological father. The court considers whether the testing was properly conducted, whether the man adopted the child, and whether the child was conceived through artificial insemination during the marriage. If all conditions are met, the court can terminate the child support obligation going forward. However, relief does not include recovering child support already paid.

Court-Ordered Genetic Testing in Mississippi

Mississippi courts have clear authority to order genetic testing in paternity cases. Under Miss. Code Ann. 93-9-21, in any case where paternity has not been established, the court — on its own motion or on the motion of any party — shall order the mother, the alleged father, and the child to submit to genetic tests.

98% probability threshold: Under Miss. Code Ann. 93-9-27, if genetic test results show a probability of paternity of 98% or greater, a rebuttable presumption of paternity is created. This presumption can only be rebutted by a preponderance of the evidence. Mississippi's 98% threshold is higher than some neighboring states — Alabama and Louisiana, for example, have different standards. The higher threshold means the DNA evidence must be particularly strong before the presumption kicks in, but once it does, the burden shifts to the other side.

Exclusion results: If the conclusions of all experts are that the alleged father is not the father of the child, the question of paternity shall be resolved accordingly. A clean exclusion effectively ends the case.

Administrative reporting: The Department of Human Services may statistically report paternity as positive to the federal Administration for Children and Families when the probability of paternity is 99% or greater, subject to a later court determination.

Refusal consequences: If a party refuses to submit to court-ordered genetic testing, the court can enforce its order or draw adverse inferences. Refusing a court-ordered DNA test in Mississippi works against the refusing party. For more on this, see our article on what happens if you refuse a paternity test.

Mississippi Department of Human Services (MDHS) — Division of Child Support Enforcement

The Division of Child Support Enforcement within the Mississippi Department of Human Services (MDHS) handles paternity establishment and child support enforcement for the state.

The Division can:

• Establish paternity for children born to unmarried parents
• Arrange genetic testing when paternity is in question
• Locate noncustodial parents
• Establish, modify, and enforce child support orders through the courts
• Distribute child support payments to families

If a custodial parent applies for child support through MDHS and the father has not been legally established, the Division will assist with the paternity process. This includes helping parents complete the ASAP form or, if the alleged father is unwilling to sign, arranging DNA testing and pursuing paternity establishment through the court system. MDHS does not represent either parent, but staff assist both sides in completing the necessary steps.

Application fee: The parent applying for child support services pays a $25 application fee, unless they are receiving SNAP, TANF, or Medicaid benefits — in which case there is no charge.

Paternity until age 21: MDHS is authorized to establish paternity at any time until the child turns 21 or is emancipated. More information is available at mdhs.ms.gov.

At-Home vs. Legal Paternity Testing in Mississippi

Mississippi does not restrict at-home DNA testing. Unlike New York, which requires a licensed physician to order genetic tests, Mississippi allows residents to purchase and use home test kits without any special permissions. No doctor's order, no state approval.

The one critical limitation:

At-home paternity test results are not admissible in Mississippi courts.

Home test results are considered "peace of mind" testing. They give you an accurate answer about biological paternity — the lab science is exactly the same — but because there is no chain of custody documentation, a Mississippi court will not accept them as evidence. No witnessed collection, no ID verification, no tamper-evident seals means no admissibility.

If you need results for a legal matter in Mississippi — child support, custody, challenging a voluntary acknowledgment, or filing a disestablishment petition — you will need a legal paternity test with full chain of custody. That means professional sample collection at an approved facility with ID verification and witnessed handling.

Many Mississippi residents start with a home test before deciding whether to pursue legal testing. It costs far less, results come back in days, and it gives you a clear answer before spending money on attorneys and court filings. If the home test confirms what you suspected, you walk into the legal process informed. If it surprises you, you can rethink your next steps before committing to anything. We cover the differences in more detail in our comparison of home vs. legal paternity testing.

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 Mississippi 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). There's no ambiguity.

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 a Mississippi court?

No. Mississippi courts require chain of custody documentation for DNA evidence — witnessed collection, government-issued ID verification, and tamper-evident packaging. A home test skips all of that. The results are scientifically accurate and fine for personal knowledge, but no Mississippi judge will admit them as evidence. For any legal matter, you need a legal paternity test collected at an approved facility.

Why does Mississippi give a full year to rescind a paternity acknowledgment?

Mississippi chose to exceed the 60-day federal minimum under Miss. Code Ann. 93-9-28. The one-year window gives fathers more time to pursue genetic testing and make an informed decision. The ASAP form itself informs the alleged father of his right to request testing through the Department of Human Services during that year. If he files for testing, the one-year clock is paused until results come back — so the window does not run out while testing is in progress.

What is the disestablishment of paternity in Mississippi?

Under Miss. Code Ann. 93-9-10, a legal father who was ordered to pay child support can petition the court to disestablish paternity if he has newly discovered DNA evidence — taken within one year before filing — showing he is excluded as the biological father. If the court grants the petition, it can terminate the child support obligation going forward. It cannot order repayment of child support already paid. The father must also show he did not adopt the child and the child was not conceived through artificial insemination during the marriage.

Is there a jury trial for paternity cases in Mississippi?

No. Under Miss. Code Ann. 93-9-27, parties to a paternity action in Mississippi are not entitled to a jury trial. The judge alone decides the case. This is not unique to Mississippi, but it is explicitly stated in the statute, so there is no ambiguity.

What is the 98% probability threshold in Mississippi?

Under Miss. Code Ann. 93-9-27, if genetic test results show a 98% or greater probability of paternity, a rebuttable presumption of paternity is created. This presumption can only be overcome by a preponderance of the evidence. The 98% threshold is higher than some states (Arkansas uses 95%, for example), meaning the DNA evidence must be particularly strong before the legal presumption applies.

Does MDHS provide free paternity testing in Mississippi?

The Division of Child Support Enforcement within MDHS can arrange genetic testing as part of a child support case. If you are receiving SNAP, TANF, or Medicaid, there is no application fee. For others, a $25 application fee applies. The division assists with scheduling DNA testing and will pursue paternity establishment through the courts if the alleged father is unwilling to sign a voluntary acknowledgment.
