(a) When a client's capacity to make adequately considered decisions in connection with a representation is diminished whether because of minority, mental impairment or for some other reason, the attorney shall, as far as reasonably possible, maintain a normal client-attorney relationship with the client.
(b) When the attorney reasonably believes that the client has diminished capacity, is at risk of substantial physical, financial, or other harm unless action is taken and cannot adequately act in the client's own interest, the attorney may take reasonably necessary protective action, including consulting with individuals or entities that have the ability to take action to protect the client and, in appropriate cases, seeking the appointment of a guardian ad litem, conservator, or guardian.
(c) Information relating to the representation of a client with diminished capacity is protected by Rule 19-301.6 (1.6). When taking protective action pursuant to section (b) of this Rule, the attorney is impliedly authorized under Rule 19-301.6 (a) (1.6) to reveal information about the client, but only to the extent reasonably necessary to protect the client's interests.
