S.C. Code Ann. § 63-15-536: Nature of authority created by order.

(A) A grant made pursuant to this subarticle is temporary and terminates pursuant to Subarticle 4 following the return from deployment of the deployed parent, unless the grant has been terminated before that time by court order. The grant does not create an independent, continuing right to caretaking authority, decision-making authority, or limited contact in an individual to whom it is granted.

(B) A nonparent granted caretaking authority, decision-making authority, or limited contact pursuant to this article has standing to enforce the grant until it is terminated pursuant to Subarticle 4 or by court order.
