S.C. Code Ann. § 34-21-260

Any trust institution in its capacity as a fiduciary or cofiduciary, whether such fiduciary capacity arose before or is created after this article takes effect, may invest funds which it lawfully holds for investment in such capacity in participations in one or more common trust funds, if such investment is not prohibited by the instrument, judgment, decree or order creating the fiduciary relationship, and if, in the case of cofiduciaries, the trust institution procures the consent of its cofiduciary or cofiduciaries to such investment.
