in the state of sc how old does a child have to be to be able to make their own decision on which parent they want to live with

This answer in no way creates a lawyer/client relationship.  This will depend on the maturity level of the child in the eyes of the Family Court Judge.  Certainly by 18 years old, the child is capable of making this type of decision, but it remains the Judges decision before this time, as to how mature the child is.
