S.C. Code Ann. § 27-40-230: Unconscionability.

(a) If the court as a matter of law, finds:

(1) a rental agreement was unconscionable when made, the court may refuse to enforce the rental agreement;

(2) any provision of a rental agreement was unconscionable when made, the court may enforce the remainder of the agreement without the unconscionable provision or limit the application of any unconscionable provision to avoid an unconscionable result; or

(3) a settlement in which a party waives or agrees to forego a claim or right under this chapter or under a rental agreement was unconscionable when made, the court may refuse to enforce the settlement, enforce the remainder of the settlement without the unconscionable provision, or limit the application of any unconscionable provision to avoid an unconscionable result.

(b) If unconscionability is put into issue by a party or by the court upon its own motion, the parties must be afforded a reasonable opportunity to present evidence as to the setting, purpose, and effect of the rental agreement or settlement to aid the court in making the determination.
