Tex. R. Disc. Prof'l. Cond. 4.03
In dealing on behalf of a client with a person who is not represented by counsel, a lawyer shall not state or imply that the lawyer is disinterested. When the lawyer knows or reasonably should know that the unrepresented person misunderstands the lawyer's role in the matter, the lawyer shall make reasonable efforts to correct the misunderstanding.
Tex. Disc. R. Prof. Cond. 4.03
Comment:
An unrepresented person, particularly one not experienced in dealing with legal matters, might assume that a lawyer is disinterested in loyalties or is a disinterested authority on the law even when the lawyer represents a client. During the course of a lawyer's representation of a client, the lawyer should not give advice to an unrepresented person other than the advice to obtain counsel. With regard to the special responsibilities of a prosecutor, see Rule 3.09.
