S.C. Code Ann. § 26-1-20

(A) Each county legislative delegation shall determine whether the endorsement of notaries public must be by: (1) one-half of the members of the legislative delegation representing the county in which the applicant resides; or (2) endorsement by the senator and representative in whose district the applicant resides, without other endorsers. (B) Each county legislative delegation shall notify the Secretary of State in writing if it chooses to utilize subsection (A)(2) within the individual county.
