S.C. Code Ann. § 9-9-70
(A) Until the first payment on account of a retirement allowance becomes normally due, any member or beneficiary may elect, by filing with the system, to convert the retirement allowance otherwise payable on his account after retirement into a retirement allowance of equivalent actuarial value under one of the optional forms named below, the retirement allowance under the option selected being due and payable on the date of retirement:
Option 1. A reduced retirement allowance payable during the retired member's life, with the provision that it continues after his death to and for the life of the beneficiary, or the trustee of the beneficiary nominated by him by written designation duly acknowledged and filed with the board at the time of retirement if the person survives him. Any retirement allowance payable under this option, except an allowance for disability retirement pursuant to Section 9-9-65, shall be subject to the incidental death benefit limitation upon the payment of survivorship benefits to a nonspouse beneficiary under Section 401(a)(9)(G) of the Internal Revenue Code and Treasury Regulation Section 1.401(a)(9)-6, Q&A-2
Option 2. A reduced retirement allowance payable during the retired member's life, with the provision that it continues after his death at one-half the rate paid to him to and for the life of the beneficiary or the trustee of the beneficiary nominated by him by written designation duly acknowledged and filed with the board at the time of retirement, if the person survives him;
Option 3. A member may elect either Option 1 or 2 with the added provision that, if the designated beneficiary predeceases the member, the retirement allowance payable to the member after the designated beneficiary's death must be equal to the retirement allowance which would have been payable had the member not elected the option;
Option 4. A member may elect Option 1 or 2 with the added provision that the reduced retirement allowance after his death is payable in equal shares to and for the life of each of two or more beneficiaries, or to the trustee or trustees of the beneficiaries, for so long as each beneficiary survives him. The benefit reduction factor must be based on the average age of the beneficiaries.
(B) A member having elected Option 1, 2, or 3 and nominated his spouse to receive a retirement allowance upon the member's death may revoke the prior nomination and elect a new option only after the death of his spouse, a divorce, or other change in the member's marital status. This change may be accomplished only by filing with the system:
