Massachusetts Rules of Professional Conduct Rule 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 or is authorized by law to do so.
Adopted June 9, 1997, effective January 1, 1998. Amended effective June 5, 2002.
 This Rule does not prohibit communication with a represented person, or an employee or agent of such a person, concerning matters outside the representation. For example, the existence of a controversy between a government agency and a private party, or between two 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 or legal authorization for communicating with a represented person 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. Counsel could also prepare and send written default notices and written demands required by such laws as Chapter 93A of the General Laws.
 Communications authorized by law also include constitutionally permissible investigative activities of lawyers representing governmental entities, directly or through investigative agents, prior to the commencement of criminal or civil enforcement proceedings, when there is applicable judicial precedent that either has found the activity permissible under this Rule or has found this Rule inapplicable. However, the Rule imposes ethical restrictions that go beyond those imposed by constitutional provisions.
 This rule applies to communications with any person, whether or not a party to a formal adjudicative proceeding, contract or negotiation, who is represented by counsel concerning the matter to which the communication relates. See the definition of "person" in Rule 9.1(h).
 In the case of an organization, this Rule prohibits communications by a lawyer for another person or entity concerning the matter in representation only with those agents or employees who exercise managerial responsibility in the matter, who are alleged to have committed the wrongful acts at issue in the litigation, or who have authority on behalf of the organization to make decisions about the course of the litigation. If an agent or employee of the organization is represented in the matter by his or her own counsel, the consent by that counsel to a communication will be sufficient for purposes of this Rule. Compare Rule 3.4(f).
 The prohibition on communications with a represented person only applies, however, in circumstances where the lawyer knows that the person is in fact represented in the matter to be discussed. This means that the lawyer has knowledge of the fact of the representation; but such knowledge may be inferred from the circumstances. See the definition of "knowledge" in Rule 9.1(f). Such an inference may arise in circumstances where there is substantial reason to believe that the person with whom communication is sought is represented in the matter to be discussed. Thus, a lawyer cannot evade the requirement of obtaining the consent of counsel by closing eyes to the obvious.
 In the event the person with whom the lawyer communicates is not known to be represented by counsel in the matter, the lawyer's communications are subject to Rule 4.3.
 Nothing in this rule prohibits a lawyer from seeking and acting in accordance with a court order permitting communication with a person known to be represented by counsel.
