Establishing Paternity

Establishing Paternity is for both parents. You must both sign a Affidavit Acknowledging Paternity at the hospital when the baby is born or you can establish paternity at a later date. This form is for people who are not married. The father’s name is added to the child’s birth certificate and the man becomes the legal father once the form is signed by both parents.

If the parents don’t complete an Affidavit Acknowledging Paternity in the hospital. They can contact the Bureau of Vital Records or the Family Support Division. – Missouri Child Support Enforcement to get an Affidavit. Staff at these offices will help parents complete the form so the father’s name can be added to the child’s birth certificate and the man can become the legal father.

If either the mother or the man who believes he may be the child’s father are not absolutely sure who the biological father is, a genetic test should be done. If the results of the genetic test show at least a 98 percent probability that the man is the father, then Missouri law says he is the presumed father.

A genetic test is done by collecting tissue samples from the mother, the man and the child. Tissue samples are usually collected by rubbing the cheeks inside the mouth with a swab. The samples are then sent to a laboratory for testing. If the results of the genetic test show at least a 98 percent probability that the man is the father, then Missouri law says he is the presumed father.
