Idaho Admin. Code r. 58.01.23.040
The initial pleading of each party must name the party's representative(s) for service and state the representative's(s') address(es) for purposes of receipt of all official documents. No more than two (2) representatives for service of documents may be listed in an initial pleading. Service of documents on the named representative(s) is valid service upon the party for all purposes in that proceeding. If no person is explicitly named as the party's representative, the person signing the pleading will be considered the party's representative. If an initial pleading is signed by more than one (1) person without identifying the representative(s) for service of documents, the presiding officer may select the person(s) upon whom documents are to be served. If two (2) or more parties or persons file identical or substantially like initial pleadings, the presiding officer may limit the number of parties or persons to be served with official documents in order to expedite the proceeding and reasonably manage the burden of service upon the parties.
