Paternity Lawyer: Missouri & Illinois

Establishing parental rights and responsibilities for fathers, mothers, and children on both sides of the Mississippi River.

Establishing paternity is about more than a name on a birth certificate. It determines parental rights, child support obligations, inheritance, and a child's access to both parents. Mary C. Neff handles paternity matters in both Missouri and Illinois courts.

How Paternity Cases Work

1

Voluntary Acknowledgment or Petition

Paternity can be established voluntarily or through a court petition, and Mary explains which path fits your situation.

2

DNA Testing (if contested)

When paternity is disputed, genetic testing provides a clear, legally recognized answer.

3

Rights & Responsibilities

Once paternity is established, Mary helps secure appropriate parenting time, support, and custody arrangements.

4

Court Order

A formal paternity order protects everyone: the child, the mother, and the father.
