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. The lawyer shall not give legal advice to an unrepresented person, other than the advice to secure counsel, if the lawyer knows or reasonably should know that the interests of such a person are or have a reasonable possibility of being in conflict with the interests of the client.

Comment:
1. 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 legal advice to an unrepresented person who may foreseeably become adverse to the client, other than the advice to obtain counsel. With regard to the special responsibilities of a prosecutor, see Rule 3.09.
2. The Rule distinguishes between situations involving unrepresented persons whose interests may be adverse to those of the lawyer's client and those in which the person's interests are not in conflict with the client's. In the former situation, the possibility that the lawyer will compromise the unrepresented person's interests is so great that the Rule prohibits the giving of any legal advice, apart from the advice to obtain counsel. Whether a lawyer is giving impermissible legal advice may depend on the experience and sophistication of the unrepresented person, as well as the setting in which the behavior and comments occur. This Rule does not prohibit a lawyer from negotiating the terms of a transaction or settling a dispute with an unrepresented person. So long as the lawyer has explained that the lawyer represents an adverse party and is not representing the person, the lawyer may inform the person of the terms on which the lawyer's client will enter into an agreement or settle a matter, prepare documents that require the person's signature, and explain the lawyer's own view of the meaning of the document or the lawyer's view of the underlying legal obligations.
3. This Rule maintains the traditional distinction between "legal advice" and "legal information" and does not restrict the latter. "Legal information" includes providing information about court rules, court terminology, and court procedure; directing to legal resources, forms, and referrals; offering educational classes and informational materials; recording on forms verbatim; reviewing forms and other documents for completeness and, if incomplete, stating why the form or document is incomplete; and explaining how to navigate a courthouse, including providing information about security requirements and directional information and explaining how to obtain access to a suit file or request an interpreter.
