S.C. Code Ann. § 20-7-738
(C) Upon receipt of a petition under this section, the family court shall schedule a hearing to be held within thirty-five days of the filing date of receipt to determine whether intervention is necessary.
The parties to the petition must be served with a summons and notices of right to counsel and of the hearing date and time along with the petition. Personal jurisdiction over the parties is effected if they are served at least seventy-two hours before the hearing. No responsive pleading to the petition is required. The court may authorize service by publication in appropriate cases and may waive the thirty-five days requirement when necessary to achieve service. A party may waive service or appear voluntarily.
