The normal client-lawyer relationship is based on the assumption that the client, when properly advised and assisted, is capable of making decisions about important matters. When the client is a minor or suffers from a diminished mental capacity, however, maintaining the ordinary client-lawyer relationship may not be possible in all respects. In particular, a severely incapacitated person may have no power to make legally binding decisions. Nevertheless, a client with diminished capacity often has the ability to understand, deliberate upon, and reach conclusions about matters affecting the client’s own well-being.  The fact that a client suffers a diminished capacity does not diminish the lawyer’s obligation to treat the client with attention and respect. Even if the person has a legal representative, the lawyer should as far as possible accord the represented person the status of client, particularly in maintaining communication. PA Rule of Prof. Conduct 1.14, under "Explanatory Comment."
None found. Cases discuss the role of the guardian, not counsel. In Pennsylvania, the power is placed in the guardian to advocate for the wishes of the person and the guardian is held to a high standard regarding their advocacy.
 The client may wish to have family members or other persons participate in discussions with the lawyer. When necessary to assist in the representation, the presence of such persons generally does not affect the applicability of the attorney-client evidentiary privilege. Nevertheless, the lawyer must keep the client’s interests foremost and, except for protective action authorized under paragraph (b), must look to the client, and not family members, to make decisions on the client’s behalf. PA Rule of Prof. Conduct 1.14, Under "Explanatory Comment." (This rule permits a third party/family to attend meetings with the lawyer where the attorney-client privilege will still apply.) Per 20 Pa.C.S. § 5521 (c)(1), each guardian of an incapacitated person shall file with the court appointing him a report, at least once within the first 12 months of his appointment and at least annually thereafter. This most likely is PA's attempt to comply with due process concerns. It shall be the duty of the guardian of the person to assert the rights and best interests of the incapacitated person. Expressed wishes and preferences of the incapacitated person shall be respected to the greatest possible extent. Where appropriate, the guardian shall assure and participate in the development of a plan of supportive services to meet the person’s needs which explains how services will be obtained. The guardian shall also encourage the incapacitated person to participate to the maximum extent of his abilities in all decisions which affect him, to act on his own behalf whenever he is able to do so and to develop or regain, to the maximum extent possible, his capacity to manage his personal affairs. 20 Pa. Cons. Stat. § 5521(a).
