S.C. Code Ann. § 15-38-15
(C) The jury, or the court if there is no jury, shall:
(3) upon a motion by at least one defendant, where there is a verdict under items (1) and (2) above for damages against two or more defendants for the same indivisible injury, death, or damage to property, specify in a separate verdict under the procedures described at subitem (b) below the percentage of liability that proximately caused the indivisible injury, death, damage to property, or economic loss from tortious conduct, as determined by item (1) above, that is attributable to each defendant whose actions are a proximate cause of the indivisible injury, death, or damage to property. In determining the percentage attributable to each defendant, any fault of the plaintiff, as determined by item (2) above, will be included so that the total of the percentages of fault attributed to the plaintiff and to the defendants must be one hundred percent. In calculating the percentage of fault attributable to each defendant, inclusion of any percentage of fault of the plaintiff (as determined in item (2) above) shall not reduce the amount of plaintiff's recoverable damages (as determined under item (2) above).
