37 CFR 11.102: Scope of representation and allocation of authority between client and practitioner.

(a) Subject to paragraphs (c) and (d) of this section, a practitioner shall abide by a client's decisions concerning the objectives of representation and, as required by § 11.104, shall consult with the client as to the means by which they are to be pursued. A practitioner may take such action on behalf of the client as is impliedly authorized to carry out the representation. A practitioner shall abide by a client's decision whether to settle a matter.

(b) [Reserved]

(c) A practitioner may limit the scope of the representation if the limitation is reasonable under the circumstances and the client gives informed consent.

(d) A practitioner shall not counsel a client to engage, or assist a client, in conduct that the practitioner knows is criminal or fraudulent, but a practitioner may discuss the legal consequences of any proposed course of conduct with a client and may counsel or assist a client to make a good-faith effort to determine the validity, scope, meaning or application of the law.
