S.C. Code § 35-5-20
Any bank or trust company incorporated under the laws of this State or any national bank located in this State may, when acting as agent, custodian or attorney in fact, upon the request of the principal, including unincorporated fiduciaries, register stocks, bonds or other securities held in such capacity in the name of a nominee or nominees of such corporate fiduciary; provided, that such bank, trust company or national bank shall not deliver or redeliver any such stocks, bonds or other securities to such unincorporated fiduciary or principal who has caused any stocks, bonds or other securities to be so registered in the name of the nominee of such bank, trust company or national bank without first causing such stocks, bonds or other securities to be registered in the name of such unincorporated fiduciary or principal as such. Any sale or transfer of such stocks, bonds or other securities made by such bank, trust company or national bank at the direction of such principal, or unincorporated fiduciary shall not be construed to be delivered or redelivered but any such bank, trust company or national bank or any nominee or nominees in whose name such securities shall be registered shall be deemed to have fully discharged its, his or their responsibilities if any such bonds, stocks or other securities are sold or transferred in accordance with the direction of the principal or unincorporated fiduciary making such deposit, and the proceeds of such sale or transfer accounted for and delivered to such unincorporated fiduciary or principal.
