A South Carolina Affidavit of Service by Mailing — Answer is a legal document used by a respondent in a lawsuit to prove service of a summons and complaint. This document is used to provide proof to the court that the respondent received the summons and complaint and, as a result, has the opportunity to respond to the allegations in the complaint. There are two types of South Carolina Affidavit of Service by Mailing — Answer documents: the Affidavit of Service by Certified Mail and the Affidavit of Service by Regular Mail. The Affidavit of Service by Certified Mail is used to provide proof that the respondent received the summons and complaint via certified mail, while the Affidavit of Service by Regular Mail is used to provide proof that the respondent received the summons and complaint via regular mail. Both documents require the respondent to provide information such as the date of service, the name and address of the respondent, and the name and address of the sender. The affidavit must be signed and notarized before it is submitted to the court.
