Professional Conduct Rules Table of Contents
(a) A person who provides information to a lawyer regarding the possibility of forming a client-lawyer relationship with respect to a matter is a prospective client.
(b) Even when no client-lawyer relationship ensues, a lawyer who has received and reviewed information from a prospective client shall not use or reveal that information except as Rule 1.9 would permit with respect to information of a former client.
(c) A lawyer subject to paragraph (b) shall not represent a client with interests materially adverse to those of a prospective client in the same or a substantially related matter if the lawyer received and reviewed information from the prospective client that could be significantly harmful to that person in the matter, except as provided in paragraph (d). If a lawyer is disqualified from representation under this paragraph, no lawyer in a firm with which that lawyer is associated may knowingly undertake or continue representation in such a matter, except as provided in paragraph (d).
(d) When the lawyer has received and reviewed disqualifying information as defined in paragraph (c), representation is permissible if:
(1) both the affected client and the prospective client have given informed consent, confirmed in writing, or:
(2) the lawyer who received and reviewed the information took reasonable measures to avoid exposure to more disqualifying information than was reasonably necessary to determine whether to represent the prospective client; and
a. the disqualified lawyer is timely screened from any participation in the matter and is apportioned no part of the fee therefrom; and
b. written notice is promptly given to the prospective client.
Ethics Committee Comment
1. The New Hampshire rule expands upon the ABA Model Rule in one area. The ABA Model Rule 1.18(a) defines a prospective client as one who “discusses” possible representation with an attorney. Similarly, ABA Model Rule 1.18(b) establishes a general rule for protection of information received in “discussions” or “consultations”.
In its version of these provisions, New Hampshire’s rule eliminates the terminology of “discussion” or “consultation” and extends the protections of the rule to persons who, in a good faith search for representation, provide information unilaterally to a lawyer who subsequently receives and reviews the information. This change recognizes that persons frequently initiate contact with an attorney in writing, by e-mail, or in other unilateral forms, and in the process disclose confidential information that warrants protection.
2. Not all persons who communicate information to an attorney unilaterally are entitled to protection under this Rule. A person who communicates information unilaterally to a lawyer, without any reasonable expectation that the lawyer is willing to discuss the possibility of forming a client-lawyer relationship (see ABA Model Rule comment No. 2); or for the purpose of disqualifying an attorney from participation in a matter; or through contemporaneous contact with numerous attorneys; is not a “prospective client” within the meaning of paragraph (a).
3. New Hampshire has concerns with ABA Comment 5, which purports to allow an attorney to secure prior “informed consent” from a prospective client that information provided in initial consultations would not preclude subsequent representation of another client in the matter. Unlike the more detailed analysis contemplated by Comment 22 to Rule 1.7, a prospective client’s prior consent may be made more quickly and less likely to be “informed” as to the potential adverse consequences of such an agreement.

RULE 1.18 DUTIES TO PROSPECTIVE CLIENT
 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.
 Not all persons who communicate information to a lawyer are entitled to protection under this Rule. A person who communicates information unilaterally to a lawyer, without any reasonable expectation that the lawyer is willing to discuss the possibility of forming a client-lawyer relationship, is not a "prospective client" within the meaning of paragraph (a).
 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 that information, except as permitted by Rule 1.9, 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.
 In order to avoid acquiring disqualifying information from a prospective client, a lawyer considering whether or not to undertake a new 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 representation.
 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.
 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.
 Under paragraph (c), the prohibition in this Rule is imputed to other lawyers as provided in Rule 1.10, but, under paragraph (d)(1), imputation may be avoided if the lawyer obtains the informed consent, confirmed in writing, 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)(i) 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.
 Notice, including a general description of the subject matter about which the lawyer was consulted, and of the screening procedures employed, generally should be given as soon as practicable after the need for screening becomes apparent.
 For the duty of competence of a lawyer who gives assistance on the merits of a matter to a prospective client, see Rule 1.1. For a lawyer's duties when a prospective client entrusts valuables or papers to the lawyer's care, see Rule 1.15.
