A South Carolina Affidavit of Service by Mailing is a legal document used to confirm that a document was served to another party by mail. It is typically used in legal proceedings to verify that the recipient was properly served with legal documents. There are two types of South Carolina Affidavit of Service by Mailing: the Affidavit of Service by Certified Mail and the Affidavit of Service by Regular Mail. The Affidavit of Service by Certified Mail must include proof of delivery, and typically requires the sender to sign a return receipt or provide a tracking number. The Affidavit of Service by Regular Mail does not require proof of delivery, but must include a statement that the envelope containing the documents was properly addressed, stamped, and mailed. Both types of Affidavits of Service by Mailing must include a detailed description of the documents that were served, the date of service, and the name and address of the person served.
