S.C. Code § 44-29-115
If the Department of Health and Environmental Control believes that a person must be isolated pursuant to Section 44-29-90, 44-29-100, or 44-29-110, it shall file a petition with the probate court of the county where the person is located or where the person resides. The complaint must state the specific harm thought probable and the factual basis for this belief. If the court, after due notice and hearing, is satisfied that the petition is well-founded, it may order that the person must be isolated.
Any person isolated pursuant to Section 44-29-90, 44-29-100, or 44-29-110 has the right to appeal to any court having jurisdiction for review of the evidence under which he was isolated.
A court may not order isolation for more than ninety days. If the department determines that the grounds for isolation no longer exist, it shall file a notice of intent to discharge with the court before the person isolated is released.
The person for whom isolation is sought must be represented by counsel at all proceedings and, if he cannot afford to hire an attorney, the court shall appoint an attorney to represent him. The attorney for the person isolated must have access to any documents regarding the isolation.
