R. Regul. Fl. Bar 4-4.3
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. In order to avoid a misunderstanding, a lawyer will typically need to identify the lawyer's client and, where necessary, explain that the client has interests opposed to those of the unrepresented person. For misunderstandings that sometimes arise when a lawyer for an organization deals with an unrepresented constituent, see rule 4-1.13(d).
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.
