The South Carolina Affidavit of Mailing is a legal document filed with the court to certify that the person filing the document has mailed certain documents to another party. It is usually used in civil matters such as divorce proceedings or other court actions. There are three types of South Carolina Affidavit of Mailing: the Unworn Declaration of Service by Mail, the Affidavit of Mailing, and the Certified Mail Receipt. The Unworn Declaration of Service by Mail is a statement that the person filing the document has sent the documents to the other party through the mail. The Affidavit of Mailing is a sworn statement that the documents have been sent by mail and that the person filing the document is aware of the contents of the documents. The Certified Mail Receipt is proof from the post office that the documents have been mailed. All three of these documents must be filed with the court to certify that the documents have been sent.
