A Pennsylvania Affidavit of Service is a legal document used to prove that legal papers have been served to the person or parties involved in a lawsuit. This document is used to demonstrate that this process has been carried out correctly and in accordance with the law. There are two types of Pennsylvania Affidavit of Service: the Affidavit of Service by Mail and the Affidavit of Service by Personal Service. The Affidavit of Service by Mail is used when the legal documents have been served to the person or parties through the mail. The Affidavit of Service by Personal Service is used when the documents have been served in person. Both types of Affidavit of Service require the signature of the person who delivered the documents and must be notarized. The Affidavit of Service must include the date, time, and place of service, the name of the person being served, and the name of the person who performed the service.
