§ 93-9-30. Full faith and credit to foreign paternity determinations

In any proceeding in Mississippi, either before a court or administrative tribunal, wherein the question of paternity may arise, and a determination or adjudication of paternity has been made through either a voluntary acknowledgement procedure, an administrative determination or a judicial order in another state or jurisdiction, then upon certification of that determination or adjudication by competent administrative or judicial authority of such state or jurisdiction, the court or administrative tribunal in Mississippi shall give full faith and credit to that foreign determination or adjudication, and it shall be conclusive proof of its substance.
