The Explanatory Comment to Pennsylvania Rule of Professional Conduct 1.18 Duties to Prospective Clients states:
“[1] Prospective clients, like clients, may disclose information to a lawyer, place documents or other property in the lawyer’s custody, or rely on the lawyer’s advice. A lawyer’s discussions with a prospective client usually are limited in time and depth and leave both the prospective client and the lawyer free (and sometimes required) to proceed no further. Hence, prospective clients should receive some but not all of the protection afforded clients.”
[2] Not all persons who communicate information to a lawyer are entitled to protection under this Rule. A person who communicates information, such as an unsolicited e-mail or other communication, to a lawyer, without any reasonable expectation that a client-lawyer relationship will be established is not a “prospective client” within the meaning of paragraphs
(1). A person who participates in an initial consultation, or communicates information, with the intent to disqualify a lawyer from representing a client with materially adverse interests is not entitled to the protections of paragraphs (b) or (c) of this Rule. A person’s intent to disqualify may be inferred from the circumstances.”
“[3] It is often necessary for a prospective client to reveal information to the lawyer during an initial consultation prior to the decision about formation of a client-lawyer relationship. The lawyer often must learn such information to determine whether there is a conflict of interest with an existing client and whether the matter is one that the lawyer is willing to undertake. Paragraph (b) prohibits the lawyer from using or revealing significantly harmful information, except as permitted by Rule1.9, even if the client or lawyer decides not to proceed with the representation. The duty exists regardless of how brief the initial conference may be.”
“[4] In order to avoid acquiring disqualifying information from a prospective client, a lawyer considering whether or not to undertake anew matter should limit the initial interview to only such information as reasonably appears necessary for that purpose. Where the information indicates that a conflict of interest or other reason for non-representation exists, the lawyer should so inform the prospective client or decline the representation. If the prospective client wishes to retain the lawyer, and if consent is possible under Rule 1.7, then consent from all affected present or former clients must be obtained before accepting the representations.”
“[5] A lawyer may condition conversations with a prospective client on the person’s informed consent that no information disclosed during the consultation will prohibit the lawyer from representing a different client in the matter. See Rule 1.0(e) for the definition of informed consent. If the agreement expressly so provides, the prospective client may also consent to the lawyer’s subsequent use of information received from the prospective client.”
“[6] Even in the absence of an agreement, under paragraph (c) the lawyer is not prohibited from representing a client with interests adverse to those of the prospective client in the same or a substantially related matter unless the lawyer has received from the prospective client information that could be significantly harmful if used in the matter.”
“[7] Under paragraph (c), the prohibition in this Rule is imputed to other lawyers as provided in Rule 1.10, but, under paragraph (d)(l), imputation may be avoided if the lawyer obtains the informed consent of both the prospective and affected clients. In the alternative, imputation may be avoided if the lawyer obtains the informed consent of both the prospective and affected clients. In the alternative, imputation may be avoided if the conditions of paragraph (d)(2) are met and all disqualified lawyers are timely screened and written notice is promptly given to the prospective client. See Rule 1 .0(k) (requirements for screening procedures). Paragraph (d)(2)(ii) does not prohibit the screened lawyer from receiving a salary or partnership share established by prior independent agreement, but that lawyer may not receive compensation directly related to the matter in which the lawyer is disqualified.”
“[8] Notice, including a description of the screened lawyer’s prior representation and of the screening procedures employed, generally should be given as soon as practicable after the need for screening becomes apparent.”
