South Carolina Amendment 1 of 2006 amended the South Carolina Constitution to make it unconstitutional for the U.S. state to recognize or perform same-sex marriages or civil unions.

[3] Unlike the other sixteen such state amendments, South Carolina's explicitly disavows any effort to prevent private contracts between same-sex partners from being recognized[4]—Virginia being the only state to do so.
