Establishing Paternity in Missouri

For unmarried parents in Missouri, welcoming a new child is a momentous occasion—but it also introduces unique legal complexities. A common misconception among unmarried fathers is that signing the birth certificate at the hospital automatically grants full parental rights.

In reality, signing a birth certificate does not give an unmarried father enforceable custody or visitation rights in Missouri. To secure these rights and protect your relationship with your child, you must formally establish legal paternity.

1. How Paternity is Established in Missouri

Missouri law recognizes three primary pathways to establish paternity for a child born outside of marriage:

A. Voluntary Acknowledgment of Paternity (VAP)

 The simplest path is for both parents to sign an Affidavit Acknowledging Paternity. This form is typically completed at the hospital immediately after the child’s birth, but it can also be submitted later to the Missouri Bureau of Vital Records. Signing this form officially places the father's name on the birth certificate and establishes legal fatherhood.

B. Administrative Paternity Orders

If the mother or the state applies for child support benefits, the Missouri Department of Social Services Family Support Division (FSD) may initiate an administrative paternity action. The FSD can order genetic testing. Under RSMo § 210.822, a DNA test result showing a 98% or greater probability legally establishes paternity.

• Important Note: An administrative order by the FSD only establishes paternity and child support obligations. The FSD does not have the legal authority to grant child custody or visitation rights.

C. Court Actions (A Paternity Lawsuit)

• If either parent disputes paternity, or if a father wants to secure official custody and visitation rights, a formal paternity petition must be filed in a Missouri circuit court. A judge can order genetic testing to resolve disputes and will issue a final legal judgment.

2. Why Establishing Paternity Matters

For both mothers and fathers, establishing legal paternity is the foundation for securing vital financial and emotional protections for the child.

For Fathers: Securing Your Rights

Until paternity is legally established, an unmarried mother holds sole legal and physical custody of the child. Establishing paternity allows a father to:

• Petition for Custody and Visitation: Request a court-ordered, legally enforceable parenting plan.

• Have a Say in Legal Decisions: Gain the right to participate in major life decisions regarding the child's education, healthcare, and religious upbringing.

For Mothers: Sharing the Responsibility

Establishing paternity ensures the child receives the support they deserve from both parents, including:

• Child Support: The legal right to seek financial support for housing, food, and daily needs.

• Medical Insurance: The ability to add the child to the father’s employer-sponsored healthcare plan.

For the Child: Benefits and Heritage

Children benefit immensely from knowing both parents. Beyond emotional ties, legal paternity gives the child access to:

• Medical Histories: Crucial genetic health information from both sides of the family.

• Financial Benefits: Eligibility for Social Security dependent benefits, military benefits, and inheritance rights.

3. The Next Step: Securing a Parenting Plan

Once paternity is established—whether through a voluntary affidavit or a DNA test—the legal journey for an unmarried father is only half complete. To protect your relationship with your child, you must file a petition in court to obtain a Judgment of Paternity, Custody, and Support.

This court order will outline a formal parenting plan, establishing a clear schedule for physical custody (visitation) and determining how legal custody decisions will be shared.
