250 CMR, § 5.08
No person, other than a Registrant holding a current License to practice in the applicable profession, shall advertise or hold themselves out as either a Professional Engineer or a Professional Land Surveyor, or use any other title to imply that they are qualified to practice engineering or land surveying in the Commonwealth, or in any other way hold themselves out as able to perform any of the Licensed Branches of engineering or land surveying.
250 CMR 5.08 shall not prohibit a person who is not registered/Licensed in Massachusetts but who holds a current License to practice in another state or Jurisdiction and who declares or otherwise qualifies his or her title in a manner that does not imply that the person is qualified to practice in Massachusetts (e.g., "Professional Engineer, Kansas" would be acceptable).
