Iowa Code Title IV. Public Health [Chs. 123-158] § 144.40. Paternity of children--birth certificates

Upon request and receipt of an affidavit of paternity completed and filed pursuant to section 252A.3A, or a certified copy or notification by the clerk of court of a court or administrative order establishing paternity, the state registrar shall establish a new certificate of birth to show paternity if paternity is not shown on the birth certificate. Upon written request of the parents on the affidavit of paternity, the surname of the child may be changed on the certificate to that of the father. The certificate shall not be marked “amended”. The original certificate and supporting documentation shall be maintained in a sealed file; however, a photocopy of the paternity affidavit filed pursuant to section 252A.3A and clearly labeled as a copy may be provided to a parent named on the affidavit of paternity.
