The initial pleading of a party (be it application, petition, protest, or motion) must identify the party's representative, if any, and state the mailing address and email address, if any, to be used for service of all documents. If a representative is identified, service of documents on the named representative is considered valid service upon the party. If an initial pleading is signed by more than one (1) person without identifying a representative for service of documents, the agency may select the person upon whom documents are to be served. A party is responsible for updating the agency with changes to its contact information for service of documents.
