Paternity

Cavanagh & Associates successfully represents you.

St. Louis Paternity Lawyer

Advocating For Fathers ' Rights in Missouri

A paternity case is a legal action to determine the father of a child. Establishing paternity is a necessary step to allow unmarried parents to gain legal rights to child custody, support, and visitation. A paternity action may be necessary if the child’s father will not voluntarily establish paternity, or the mother will not recognize the father.

If paternity is in question, an experienced attorney can guide you through the necessary steps to establish or contest custody, parenting time, or child support. At Cavanagh & Associates, we help clients with paternity matters in and around St. Louis, St. Charles, Chesterfield, and the surrounding communities. Led by Jack Cavanagh, a St. Louis paternity lawyer with well over 50 years of legal experience, we know how to effectively represent our clients’ interests in these often emotional and challenging cases.

How Is Paternity Established In Missouri?

Different states often have varying methods of establishing paternity. In Missouri, either of the biological parents can file a petition to establish paternity within state court or with the Missouri Family Support Division. Once this has been established, the opposing party (other biological parent) has 30 days to file an answer.

In Missouri, paternity may be established in two ways:

  • Paternity can be established by DNA testing, but may not be necessary in all cases. It will be necessary if the identity of the biological father is unclear
  • Paternity can also be determined by signing an affidavit acknowledging paternity in Missouri. This is the easiest method and can be done even if it was not signed at the time of the child's birth

How Long Does a Father Have to Establish Paternity in Missouri?

The Missouri paternity statute states that the father may establish paternity up until the child turns 18 years of age. The child has until the age of 21 to establish paternity themselves.

Does Paternity Influence Parental Rights & Responsibilities?

Paternity may influence one’s parental rights and responsibilities in various ways:

  • Establishing paternity may grant a father the right to custody or parenting time with his child.
  • Establishing paternity may grant a mother the right to pursue child support from the father.
  • Challenging paternity may prevent a man from gaining custody or parenting time with a child.
  • Challenging paternity may help a man avoid paying support for a child that is not his.

Commonly Asked Questions

What steps should I take to establish paternity in St. Louis?

To establish paternity in St. Louis, you can file a petition in state court or with the Missouri Family Support Division. If the biological father’s identity is uncertain, DNA testing may be required. Alternatively, if both parents agree, they can sign an affidavit acknowledging paternity, which is a straightforward process. It’s advisable to consult with a knowledgeable attorney who can guide you through the legal requirements and help ensure that your rights and the child's best interests are protected.

How does establishing paternity affect child support in Missouri?

Establishing paternity is crucial for child support matters in Missouri. Once paternity is legally recognized, the mother can pursue child support from the father. This ensures that the child receives financial support from both parents, which is essential for their upbringing. If paternity is contested, it may complicate the process of obtaining support. Therefore, understanding your rights and obligations regarding paternity can significantly impact your financial responsibilities and the welfare of your child.
