S.C. Code Ann. § 62-2-114
Notwithstanding any other provision of law, if the parents of the deceased would be the intestate heirs pursuant to Section 62-2-103(2), upon the motion of either parent or any other party of potential interest based upon the decedent having died intestate, the probate court may deny or limit either or both parent's entitlement for a share of the proceeds if the court determines, by a preponderance of the evidence, that the parent or parents failed to reasonably provide support for the decedent as defined in Section 20-7-40 and did not otherwise provide for the needs of the decedent during his or her minority.
