Iowa Code § 600B.36: Report to registrar of vital statistics.

Upon the entry of a judgment determining the paternity of a child the clerk of the district court shall notify in writing the state registrar of vital statistics of the name of the person against whom such judgment has been entered, together with such other facts disclosed by the records as may assist in identifying the record of the birth of the child as the same may appear in the office of said registrar. If such judgment shall thereafter be vacated that fact shall be reported by the clerk in the same manner.
