(a) Title to real property previously treated as being subject to the jurisdiction of the State of South Carolina but that is recognized as being within the boundaries of this State as a result of the certification of the boundary is not affected by the certification of the boundary or the recognition of the real property as being within the boundaries of this State. All conveyances and instruments of title, of any sort, made prior to the certification of the boundary shall be recognized and given full faith and credit in this State according to the law, jurisdiction, and terms in effect at the time of the conveyance in the jurisdiction the property was previously treated as being subject to. For the purposes of this subsection, “instruments of title” means any instrument that affects title or constitutes the chain of title to real property, including, but not limited to, all deeds, wills, estate documents evidencing transfer of title, plats, surveys, easements, rights-of-way, outstanding mortgages and deeds of trust, judicial orders or decrees, and documents evidencing intestate succession.

(b) Liens recorded prior to the date of boundary certification with the register of deeds or docketed with the clerk of superior court in the county in this State where the affected parcel is situated shall attach, as a class, to the affected parcel as of the effective date and time of the boundary certification. This class of liens shall be assigned priority as of the date of boundary certification but shall retain the same priority among themselves as if this subsection did not apply.
