02-280-8 Me. Code R. § 7
A licensee has an obligation to maintain and respect the confidentiality of information obtained in the performance of all professional activities. Maintaining such confidentiality is vital to the proper performance of the licensee's professional activities.
A licensee shall not use or disclose, or permit others within the licensee's control to use or disclose, any confidential client or employer information without the consent of the client or employer. This obligation continues after the termination of the relationship between the licensee and the client or employer and extends to information obtained by the licensee in professional relationships with prospective clients and employers.
This principle shall not be construed to prohibit a licensee from disclosing information as required to meet professional or legal obligations.
