S.C. Code Ann. § 44-63-90
When the birth of a person born in the State has not been registered, a certificate may be filed subject to these regulations prescribed by the state registrar of vital statistics. However, when it appears that an applicant for a certificate of birth cannot produce minimum prescribed documentation, satisfactory as to validity, to the state registrar, the applicant may be denied a certificate of birth and advised as to the reason for the denial. No delayed birth certificate may be registered for a deceased person.
