S.C. Code § 31-3-1110
If any county withdraws from a regional authority under the provisions of Sections 31-3-1090 and 31-3-1100, and it is subsequently determined by a court of competent jurisdiction that the county was, in fact, identified with any aggregate obligation or indebtedness of the regional authority for funds expended prior to its withdrawal from the region, which was not disclosed prior to withdrawal from the regional authority, the county housing authority shall thereupon assume its proportionate share of such aggregate obligation, but only in the manner and to the extent such obligation would apply to the county as a member of the regional authority.
Any county withdrawing from a regional authority pursuant to Sections 31-3-1090 and 31-3-1100 shall not be subject to the provisions of Sections 31-3-1060, 31-3-1070 and 31-3-1080.
