Establishing Paternity: Legal Steps and Implications for Parents

Howard L. Lotven, P.C. March 29, 2025

In Missouri, establishing paternity is an essential legal step for parents who want to secure the rights and responsibilities associated with their child's upbringing. At Howard L. Lotven, P.C., I understand that this process can be an emotionally charged and challenging experience. 

However, it’s important to recognize that establishing paternity is a significant part of family law, and it has profound implications for both the child and the parents. Here, I’ll explore the legal steps involved in establishing paternity in Kansas City, Missouri, and the potential legal and emotional effects for parents.

Paternity and Its Importance

Paternity refers to the legal recognition of a father’s relationship to his child. It’s a crucial aspect of family law because it determines the legal rights and obligations of a father, including financial support, inheritance rights, and the ability to make important decisions about the child’s welfare. 

Establishing paternity also plays an essential role in determining custody and visitation rights, as well as access to certain benefits for the child, such as insurance or social security.

For mothers, establishing paternity provides a means to hold the father accountable for child support and other financial responsibilities. For fathers, it confirms recognition of their parental rights and provides an opportunity for them to be involved in their child's life.

Legal Steps to Establish Paternity in Missouri

There are several ways to establish paternity in Missouri through family law, each with its own process and requirements. The state allows both voluntary and involuntary methods for establishing paternity, and the correct path will depend on the circumstances of the case.

1. Acknowledgment of Paternity

The most straightforward and common method of establishing paternity is through a voluntary acknowledgment of paternity. This is a formal legal declaration that the father accepts responsibility for the child. In Missouri, this process is typically completed at the time of the child's birth.

If both parents are present at the hospital, they may sign a voluntary acknowledgment form, which is filed with the Missouri Bureau of Vital Records. Once signed, the father's name is placed on the child’s birth certificate, and the legal relationship between the father and the child is established.

If the father is not present during the birth or if the parents choose not to complete the acknowledgment at that time, the father can still sign an acknowledgment of paternity at a later date. This can be done at a local Family Support Division office or another designated location.

It’s important to note that the acknowledgment is legally binding once signed. If there is any doubt about the father’s paternity or the parties are not certain of the child’s biological father, it’s recommended to seek legal advice before completing this step.

2. DNA Testing

In some cases, the father may not be sure of his paternity, or there may be a dispute about who the biological father is. In such instances, DNA testing can be used to establish paternity. DNA testing is a highly accurate way of determining biological relationships, with a test typically providing results with a 99.9% accuracy rate.

The process begins when one or both parties file a petition with the court to request DNA testing. This is usually done in cases where there is a dispute about paternity or if one parent refuses to acknowledge the father’s paternity under family law.

Once the court orders the DNA test, a sample is collected from the mother, child, and alleged father. The samples are then sent to a laboratory for analysis, and the results are provided to the court. If the test confirms that the man is the biological father, the court will issue an order establishing paternity.

In Missouri, parents may also request DNA testing through the Missouri Family Support Division, which provides paternity testing services. This is often part of child support enforcement efforts when paternity is in question.

3. Court Order for Paternity

In situations where the parents are unable or unwilling to voluntarily acknowledge paternity, a court order may be necessary to establish legal paternity. This typically occurs in family law disputes, such as child custody or child support cases.

One or both parents may file a petition in family court to request a determination of paternity. The court may order DNA testing or consider other evidence to make a determination. If paternity is established, the court will issue an order, granting the father legal rights and responsibilities regarding the child, including child support and custody.

If the father is found to be the biological parent, the court will also address other important matters such as child custody, visitation rights, and child support. In Missouri, the courts follow specific guidelines for determining child support and custody based on the best interests of the child.

Implications of Establishing Paternity

Establishing paternity carries significant legal and emotional implications for both parents and the child. Once paternity is established, it triggers certain rights and responsibilities that affect the entire family.

1. Parental Rights and Responsibilities

For fathers, establishing paternity grants legal rights, including the right to seek custody or visitation, as well as the ability to make decisions about the child’s upbringing, such as education, healthcare, and religious upbringing. It also imposes responsibilities, including the obligation to pay child support.

For mothers, establishing paternity helps confirm that the father contributes to the child’s financial support and is held accountable for his parental duties. It also provides the opportunity for the mother and father to make joint decisions regarding the child's welfare.

2. Custody and Visitation

One of the most important outcomes of establishing paternity is the ability to seek custody or visitation rights. In Missouri, both parents have the right to request custody or visitation, regardless of whether they were married at the time of the child’s birth. 

Establishing paternity through family law is essential for fathers who wish to be involved in their child’s life, as it grants them legal standing in custody and visitation matters.

If paternity is established, either parent may file for custody or visitation through the court system. The court will then determine custody arrangements based on the best interests of the child. This may include joint custody, sole custody, or visitation schedules.

3. Child Support

Another significant implication of establishing paternity is the imposition of child support obligations. Once paternity is established, the father is legally obligated to provide financial support for the child, regardless of the custody arrangement. 

In Missouri, child support amounts are determined based on the Missouri Child Support Guidelines, which take into account both parents’ income and the child’s needs.

If the parents cannot agree on child support, the court will determine an appropriate amount. Establishing paternity also allows for enforcement of child support payments through the Missouri Family Support Division, which has the authority to collect and enforce payments.

4. Emotional and Legal Stability

For children, the establishment of paternity provides emotional and legal stability. Children benefit from knowing both parents are legally recognized and can have relationships with both mother and father. 

Additionally, children may gain access to benefits such as health insurance, social security, or inheritance rights that would not be available without legal paternity.

Challenges and Disputes in Paternity Cases

While establishing paternity is an important step, it can also lead to disputes, especially if one party is unwilling to cooperate. Some common challenges include:

  • Refusal to acknowledge paternity: In some cases, the alleged father may deny paternity and refuse to cooperate with DNA testing or voluntary acknowledgment.

  • Paternity fraud: In rare instances, paternity can be disputed if there is a belief that the wrong individual is being identified as the father.

  • Custody disputes: Once paternity is established, disagreements over custody, visitation, and child support may arise.

If you’re facing a paternity dispute, it’s essential to seek guidance from a family law attorney to help you understand your rights and legal options.
