Miss. Code § 41-57-19
Any person who was born in the State of Mississippi and whose birth has not been registered and who is unable to secure the proof now required by the registrar of births to register the same, may file a petition under oath in the chancery court of the county of the residence of the petition, or in any chancery court district of the state if the petitioner be a non-resident, setting out the true date of the birth of the petitioner and other facts necessary. The clerk shall issue a summons for the State Board of Health, which summons may be served on the executive secretary, the registrar of vital statistics or a duly qualified county registrar, thirty (30) days prior to the time of the hearing, to appear and contest the same. Alternatively process can be waived as provided by Section 13-3-71. The said petition may be heard by the chancellor in term time or in vacation, and the same shall not be taken as confessed, but proof shall be made of the allegation in the same. When a decree is entered adjudicating the true date of the birth of the petitioner, upon a certified copy of the decree being furnished to the registrar of vital statistics showing the true date of the birth of the petitioner, the same shall be registered upon the proper records of the State Board of Health.
