S.C. Code § 43-5-70
The department shall require that all persons applying for assistance shall provide acceptable identification and proof of residence and the department shall by regulation specify what constitutes adequate identification and proof of residence. The department shall require that all reports of employment or income be verified by letter or direct contact with the employer of the applicant or recipient and if the verification is made by letter, a stamped self-addressed envelope shall be enclosed and request for prompt return shall be made. The department shall verify all other information related to the eligibility in any case in which there is reason to believe that the applicant has falsified, misrepresented, or omitted any material facts such as age and number of children, real and personal property, including bank accounts and insurance policies or any other resources. No person shall be eligible for aid to families with dependent children unless he is a resident of the State.
If a recipient is or will be absent from the State for a period of thirty days or longer, the department shall consider the recipient ineligible for assistance.
It is not the intent of the General Assembly in enacting this section to create any durational residence requirement.
