Iowa R. Prof. Cond. 32:7.1
A lawyer shall not make a false or misleading communication about the lawyer or the lawyer's services. A communication is false or misleading if it contains a material misrepresentation of fact or law, or omits a fact necessary to make the statement considered as a whole not materially misleading.
Iowa. R. Prof. Cond. 32:7.1
Comment
[1] This rule governs all communications about a lawyer's services, including advertising. Whatever means are used to make known a lawyer's services, statements about them must be truthful.
[2] Misleading truthful statements are prohibited by this rule. A truthful statement is misleading if it omits a fact necessary to make the lawyer's communication considered as a whole not materially misleading. A truthful statement is misleading if a substantial likelihood exists that it will lead a reasonable person to formulate a specific conclusion about the lawyer or the lawyer's services for which there is no reasonable factual foundation. A truthful statement is also misleading if presented in a way that creates a substantial likelihood that a reasonable person would believe the lawyer's communication requires that person to take further action when, in fact, no action is required.
[3] A communication that truthfully reports a lawyer's achievements on behalf of clients or former clients may be misleading if presented so as to lead a reasonable person to form an unjustified expectation that the same results could be obtained for other clients in similar matters without reference to the specific factual and legal circumstances of each client's case. Similarly, an unsubstantiated claim about a lawyer's or law firm's services or fees, or an unsubstantiated comparison of the lawyer's or law firm's services or fees with those of other lawyers or law firms, may be misleading if presented with such specificity as would lead a reasonable person to conclude that the comparison or claim can be substantiated. The inclusion of an appropriate disclaimer or qualifying language may preclude a finding that a statement is likely to create unjustified expectations or otherwise mislead the public.
[4] It is professional misconduct for a lawyer to engage in conduct involving dishonesty, fraud, deceit, or misrepresentation. Rule 32:8.4(c). See also rule 32:8.4(e) for the prohibition against stating or implying an ability to improperly influence a government agency or official or to achieve results by means that violate the Iowa Rules of Professional Conduct or other law.
[5] Firm names, letterhead, and professional designations are communications concerning a lawyer's services. A firm may be designated by the names of all or some of its current members, by the names of deceased members where there has been a succession in the firm's identity, or by a trade name if it is not false or misleading. A lawyer or law firm also may be designated by a distinctive website address, social media username, or comparable professional designation that is not misleading. A law firm name or designation is misleading if it implies a connection with a government agency, with a deceased lawyer who was not a former member of the firm, with a lawyer not associated with the firm or a predecessor firm, with a nonlawyer, or with a public or charitable legal services organization. If a firm uses a trade name that includes a geographical name such as "Springfield Legal Clinic," an express statement explaining that it is not a public legal aid organization may be required to avoid a misleading implication.
[6] A law firm with offices in more than one jurisdiction may use the same name or other professional designation in each jurisdiction.
[7] Lawyers may not imply or hold themselves out as practicing together in one firm when they are not a firm, as defined in rule 32:1.0(c), because to do so would be false and misleading.
[8] It is misleading to use the name of a lawyer holding a public office in the name of a law firm, or in communications on the law firm's behalf, during any substantial period in which the lawyer is not actively and regularly practicing with the firm.
