S.C. Code § 9-18-80
If a member terminates membership in a retirement system by withdrawal of contributions, the retirement system shall pay all or a portion of the amount withdrawn to any alternate payee as directed by a qualified domestic relations order. Any qualified domestic relations order previously accepted with respect to the member's benefits under that system is thereafter void. If the former member later resumes membership in the retirement system, no portion of any benefits subsequently payable on account of the member must be paid to the alternate payee, even if those benefits result in part from reinstatement of service credit initially credited during the marriage, unless the retirement system receives a qualified domestic relations order specifically requiring it to make the payments to the alternate payee.
