Iowa Law Overview

Procedures to establish paternity and to compel child support by the father can be found in Iowa Code chapters 252F (PDF) and 600B (PDF)

Is a blood test required?

In a case to establish paternity, the court may, on its own motion or at the request of a party, require the child, mother, and alleged father to submit to blood or genetic tests. The party requesting testing must file a written motion with the clerk of court and provide copies to the opposing parties. The judge will then consider the request.

Is a blood or genetic test conclusive?

If an expert concludes that the test results show that the alleged father is not excluded and that the probability of the alleged father’s paternity is ninety-five percent or higher, there is a rebuttable presumption that the alleged father is the father. This presumption can be rebutted only by clear and convincing evidence. 

What if I want to challenge paternity that was previously established?

Iowa law provides that under certain circumstances paternity that was previously established may be overcome if subsequent blood or genetic testing indicates that the established father of a child is not the child’s biological father.
