Is a blood or genetic test required to prove who the father is?

In a case to establish paternity, the court may 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. See Iowa Code § 600B.41. There may be fees for blood or genetic tests.

If an expert concludes that the test results show that the probability of the alleged father’s paternity is 95% or higher, there is a presumption that the alleged father is the father. This presumption can be disproved only by clear and convincing evidence.
