A Certificate of Service for Sealed Documents Filed Under Interim Circuit Rule 27-13 is a document used to certify that a document has been properly served to all parties in a legal matter. It is used to prove that a document was filed with the court and that all the necessary parties have been notified of the filing. The certificate is signed by the party filing the document, an attorney, or a process server and attests to the delivery of the document. There are two types of Certificate of Service for Sealed Documents Filed Under Interim Circuit Rule 27-13: a traditional certificate of service and an electronic certificate of service. The traditional certificate of service is used to certify that a document was sent by mail, fax, or other means of delivery to the other parties involved in the legal matter. The electronic certificate of service is used to certify that a document was electronically filed with the court and that all the necessary parties have been notified of the filing. In either case, the certificate must include the names of all parties served, the date the document was served, and the method of service.
