S.C. Code Ann. § 38-69-30: Nontransferability of annuity death benefits left with insurance company under a trust or other agreement.

When the proceeds of an annuity becoming a claim by the death of the insured are left with an insurance company under a trust or other agreement, the benefits accruing under the agreement after the death of the insured are not transferable nor subject to computation or incumbrance nor to legal process, except in an action to recover for necessaries if the parties to the trust or other agreement so agree.
