S.C. Code § 15-61-11
Notwithstanding the provisions of Section 15-61-10, the right to compel judicial partition of lands may be waived by tenants-in-common owning land upon which is to be constructed or has been constructed an electric generating plant producing electric energy for sale or distribution within or without this State, provided the effective period of such waiver does not extend beyond the operating life of the generating plant. If notice is given by the recording of a deed or instrument of conveyance creating a tenancy-in-common and containing an expression of agreement to waive the right of judicial partition, then such agreement shall run with the land and shall be binding upon the heirs, successors and assigns of any tenant-in-common so bound. The power and right to enter into agreements to waive the right of judicial partition authorized by this section shall be in addition to any such powers and rights already authorized by the laws of South Carolina.
