Okla. Stat. tit. 5, Rule 7.5
Oklahoma Rules of Professional Conduct
Chapter 1, App. 3-A
Information About Legal Services
(d) Lawyers shall not state or imply that they practice in a partnership or other organization unless that is the fact.
Comments
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." 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 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. With regard to paragraph (d), lawyers sharing office facilities, but who are not in fact partners, may not denominate themselves as, for example, "Smith and Jones," for that title suggests partnership in the practice of law. Code Comparison Rule 7.5 is substantially identical to DR 2-105. Oklahoma Modification The language of Oklahoma DR 2-105 is adopted in lieu of ABA Rule 7.5. However, the Oklahoma Rule does not vary in significant respects from the ABA Rule. See the discussion in OKLAHOMA MODIFICATION under Rule 7.1. Historical Data Adopted effective July 1, 1988.
