RULE 4-4.2 COMMUNICATION WITH PERSON REPRESENTED BY COUNSEL
In representing a client, a lawyer shall not communicate about the subject of the representation with a person the lawyer knows to be represented by another lawyer in the matter, unless the lawyer has the consent of the other lawyer. Notwithstanding the foregoing, an attorney may, without such prior consent, communicate with another's client in order to meet the requirements of any statute or contract requiring notice or service of process directly on an adverse party, in which event the communication shall be strictly restricted to that required by statute or contract, and a copy shall be provided to the adverse party's attorney.
Comment
This rule does not prohibit communication with a party, or an employee or agent of a party, concerning matters outside the representation. For example, the existence of a controversy between a government agency and a private party, or between 2 organizations, does not prohibit a lawyer for either from communicating with nonlawyer representatives of the other regarding a separate matter. Also, parties to a matter may communicate directly with each other and a lawyer having independent justification for communicating with the other party is permitted to do so. Communications authorized by law include, for example, the right of a party to a controversy with a government agency to speak with government officials about the matter.
In the case of an organization, this rule prohibits communications by a lawyer for 1 party concerning the matter in representation with persons having a managerial responsibility on behalf of the organization and with any other person whose act or omission in connection with that matter may be imputed to the organization for purposes of civil or criminal liability or whose statement may constitute an admission on the part of the organization. If an agent or employee of the organization is represented in the matter by the agent's or employee's own counsel, the consent by that counsel to a communication will be sufficient for purposes of this rule. Compare rule 4-3.4(f). This rule also covers any person, whether or not a party to a formal proceeding, who is represented by counsel concerning the matter in question.
