How to Establish Paternity in Mississippi

Reviewed by DocDraft Legal Team · Mississippi · Last updated 2026-09-12

In Mississippi, establishing paternity means legally identifying a child's father so the child gains rights to support, custody and visitation, health coverage, inheritance, and benefits. The area is governed by the Mississippi Uniform Law on Paternity in Title 93, Chapter 9. Unmarried parents who agree can sign an Acknowledgment of Paternity, which when properly completed has the same legal effect as a court order establishing paternity. When parents do not agree, a paternity action decides the question. Mississippi's load-bearing timing rule is generous: a paternity action may be brought at any time until the child attains the age of 21, unless the child has been emancipated (Miss. Code Ann. 93-9-9). A child born to a married woman is presumed to be the husband's child, a presumption that can be rebutted with genetic evidence. Genetic testing is powerful: under Miss. Code Ann. 93-9-27, a probability of paternity of 98 percent or greater creates a rebuttable presumption of paternity that affects the burden of proof, which the disputing party must overcome by a preponderance of the evidence. Under federal law, either parent may rescind a signed acknowledgment within 60 days. Attorney review of your situation is available through DocDraft.

What are the ways to establish paternity in Mississippi?

There are two routes. Unmarried parents who agree can sign an Acknowledgment of Paternity, which has the same legal effect as a court order establishing paternity. If parents disagree, a paternity action is filed under the Mississippi Uniform Law on Paternity and the court can order genetic testing before deciding (Miss. Code Ann. 93-9-9).

How long do I have to establish paternity in Mississippi?

Mississippi allows a long window. A paternity action may be brought at any time until the child attains the age of 21, unless the child has been emancipated (Miss. Code Ann. 93-9-9). That gives parents and the child a wide period to seek a legal determination of parentage.

What genetic-testing result establishes paternity in Mississippi?

Under Miss. Code Ann. 93-9-27, if genetic tests show a probability of paternity of 98 percent or greater, a rebuttable presumption of paternity arises that affects the burden of proof. The party disputing the result must then overcome it by a preponderance of the evidence.

What is the marital presumption of paternity in Mississippi?

Mississippi recognizes a presumption that a child born to a married woman is the child of her husband. The presumption can be rebutted in court, most persuasively with genetic testing that excludes the husband, and the paternity of another man can then be established under the Uniform Law on Paternity.

Mississippi paternity law at a glance

Mississippi governs paternity through the Uniform Law on Paternity in Title 93, Chapter 9. Unmarried parents who agree can establish parentage without a hearing by signing an Acknowledgment of Paternity, which when properly completed has the same legal effect as a court order. What stands out in Mississippi is the long filing window: a paternity action may be brought at any time until the child attains the age of 21, unless the child has been emancipated (Miss. Code Ann. 93-9-9). A child born to a married woman is presumed to be the husband's child, and that presumption can be rebutted with genetic testing. Genetic evidence is decisive: under Miss. Code Ann. 93-9-27, a probability of paternity of 98 percent or greater creates a rebuttable presumption that affects the burden of proof, which the disputing party must overcome by a preponderance of the evidence.

Establishing Mississippi paternity for a child born to unmarried parents

Suppose a child is born in Mississippi to unmarried parents who agree on the father. At the hospital both sign an Acknowledgment of Paternity, which when properly completed has the same legal effect as a court order establishing paternity. Weeks later one parent has second thoughts and can still rescind within 60 days of signing under the federal rule that applies in Mississippi. Had the parents disputed parentage instead, either could file a paternity action, which may be brought at any time until the child attains the age of 21 unless emancipated (Miss. Code Ann. 93-9-9). The court could order genetic testing, where a probability of paternity of 98 percent or greater creates a rebuttable presumption that shifts the burden of proof (Miss. Code Ann. 93-9-27). Attorney review is available through DocDraft.

Suggested Compliance Checklist

Confirm whether the child was born to a married woman

Before signing or filing anything days after starting

Determine whether the child was born to a married woman, which triggers Mississippi's presumption that the husband is the father. Rebutting it requires a court action and typically genetic testing that excludes the husband before another man's paternity can be established.

Get genetic testing if biological parentage is uncertain

Before signing an acknowledgment days after starting

Because a signed acknowledgment carries the force of a court order, obtain genetic testing first if there is any doubt. Under Miss. Code Ann. 93-9-27, a probability of paternity of 98 percent or greater creates a rebuttable presumption that shifts the burden of proof.

Sign and file the Acknowledgment of Paternity

At the hospital or a local office days after starting

Unmarried parents who agree sign the Acknowledgment of Paternity, provided through the State Department of Health and the Department of Human Services, giving it the effect of a court order. Keep a copy. Attorney review of your paternity matter is available through DocDraft.

Track the federal 60-day rescission window

Within 60 days of signing days after starting

If you need to cancel a signed acknowledgment, rescind within 60 days of signing under the federal rule that applies in Mississippi. After 60 days it can be challenged only on the basis of fraud, duress, or a material mistake of fact.

File a paternity action if parents disagree

Before the child's twenty-first birthday days after starting

If parents do not agree, file a paternity action under the Uniform Law on Paternity, which may be brought at any time until the child attains the age of 21 unless emancipated (Miss. Code Ann. 93-9-9). The court can order genetic testing and enter an order with support terms.

Keep records of the acknowledgment, testing, and orders

Ongoing days after starting

Save copies of the signed acknowledgment, any genetic-test results, and court papers, and calendar the child's twenty-first birthday as the outer filing limit and the federal 60-day rescission window so you do not miss a right-forfeiting date.
