S.C. Code Ann. § 37-5-113

An action by a creditor against a consumer arising from a consumer credit transaction shall be brought in the county of the consumer's residence [Section 37-1-201(6)], unless an action is brought to enforce an interest in land securing the consumer's obligation, in which case the action may be brought in the county in which the land or a part thereof is located. If the county of the consumer's residence has changed, the consumer upon motion may have the action removed to the county of his current residence. If the residence of the consumer is not within this State, the action may be brought in the county in which the sale, lease or loan was made. If the initial papers offered for filing in the action on their face show noncompliance with this section, the clerk of court shall not accept them. The court may change the place of trial as otherwise provided by law.
