S.C. Code Ann. § 15-78-190: Compensation of plaintiff pursuant to underinsured or uninsured defendant provisions of plaintiff's insurance policy.

If the amount of the verdict or judgment is not satisfied by reason of the monetary limitations of this chapter upon recovery from the State or political subdivision thereof, the plaintiff's insurance company, subject to the underinsured and uninsured defendant provisions of the plaintiff's insurance policy, if any, shall compensate the plaintiff for the difference between the amount of the verdict or judgment and the payment by the political subdivision. If a cause of action is barred under SECTION 15-78-60 of the 1976 Code, the plaintiff's insurance company must compensate him for his losses subject to the aforementioned provisions of his insurance policy.
