The Certificate of Service is a sworn statement that is signed by the person performing the service, and it must be filed with the clerk of the court as proof that the defendant was properly served. There are two types of Florida Certificates of Service. The first is a Certificate of Service by Mail, which is used when the documents are served by mail. The second type is a Certificate of Service by Personal Service, which is used when the documents are served in person.
