Who may represent a party in arbitration in New Jersey is a recurring issue without a definitive answer. Looking at arbitration's historic roots in medieval guilds and contemporary business associations, parties in commercial arbitration have been allowed to select a representative that best fits their needs and predilections, whether the party is an individual or an entity or the representative is a lawyer, accountant, financial advisor or other professional. The commercial rules for some of the best-known arbitration forums, such as the American Arbitration Association, JAMS, or the CPR, reflect this flexibility, though the AAA rules acknowledge the obvious caveat—that a party's choice of representation will be respected unless otherwise affected by "law," such as a statute or ethics or other rule.
