Haw. R. Prof. Cond. 7.5
 A firm may be designated by the names of all or some of its members, by the names of deceased members where there has been a continuing succession in the firm's identity or by a trade name such as the "ABC Legal Clinic." A lawyer or law firm may also be designated by a distinctive website address or comparable professional designation. Although the United States Supreme Court has held that legislation may prohibit the use of trade names in professional practice, use of such names in law practice is acceptable so long as it is not misleading. If a private firm uses a trade name that includes a geographical name such as "Springfield Legal Clinic," an express disclaimer that it is not a public legal aid agency may be required to avoid a misleading implication. It may be observed that any firm name including the name of a deceased partner is, strictly speaking, a trade name. The use of such names to designate law firms has proven a useful means of identification. However, it is misleading to use the name of a lawyer not associated with the firm or a predecessor of the firm or the name of a nonlawyer. See Ruleof the Rules of the Supreme Court of the State of Hawai'i, governing the naming of Lawyers' Professional Business Organizations.
 With regard to paragraph (e), lawyers sharing office facilities, but who are not in fact associated with each other in a law firm, may not denominate themselves as, for example, "Smith and Jones," for that title suggests that they are practicing law together in a firm.
