S.C. Code Ann. § 20-1-230
(A) The judge of probate or clerk of court with whom a marriage license application was filed shall issue a license upon:
(B) A man and a woman who successfully complete a qualifying premarital preparation course and who have a South Carolina marriage license which attests the completion of the course shall be entitled to receive a one-time fifty-dollar non-refundable state income tax credit, as permitted in Section 12-6-3381. In order for the course to qualify pursuant to this section, the couple must:
(4) complete the course together rather than individually.
A couple who completes a premarital preparation course pursuant to this section must be issued a certification of completion at the conclusion of the course by their course provider. The certification must include the number of hours that the couple completed together and the credentials of the course provider. A couple must produce this certification when applying for the marriage license in order to receive the non-refundable state income tax credit. The judge of probate or clerk of court must certify on the marriage license that the couple met the statutory requirements to qualify for this income tax credit. The judge of probate court or clerk of court is not responsible to authenticate the information contained in the certification of completion unless the certification of completion is wholly fraudulent on its face.
