S.C. Code Regs. § § 19-701.06
The Ethics Act governs the employment of family members and conflicts of interest. For additional information consult the Ethics Act (Section 8-13-100 through Section 8-13-1520 of the South Carolina Code of Laws), the Ethics Commission opinions, and the State Ethics Commission.
No public official, public member, or public employee may cause the employment, appointment, promotion, reassignment, transfer, or advancement of a family member to a State or local office or position in which the public official, public member, or public employee supervises or manages. Family member means an individual who is (a) the spouse, parent, brother, sister, child, mother-in-law, father-in-law, son-in-law, daughter-in-law, grandparent, or grandchild, or (b) a member of the individual's immediate family. Immediate family is defined as follows:
No employee may accept any work or compensation that could be reasonably construed as a conflict of interest. Acceptance without proper prior approval of work assignment or compensation that is found to be a conflict of interest may be grounds for disciplinary action or termination. The propriety of an employment situation or compensation for services rendered shall be considered by all parties concerned. Counsel from the Office of the Attorney General or the State Ethics Commission may be necessary to make such determinations.
