Massachusetts Rules of Professional Conduct Rule 1.16: Declining or Terminating Representation
(a) Except as stated in paragraph (c), a lawyer shall not represent a client or, where representation has commenced, shall withdraw from the representation of a client if:
(1) the representation will result in violation of the rules of professional conduct or other law;
(2) the lawyer's physical or mental condition materially impairs the lawyer's ability to represent the client; or
(3) the lawyer is discharged.
(b) Except as stated in paragraph (c), a lawyer may withdraw from representing a client if withdrawal can be accomplished without material adverse effect on the interests of the client, or if:
(1) the client persists in a course of action involving the lawyer's services that the lawyer reasonably believes is criminal or fraudulent;
(2) the client has used the lawyer's services to perpetrate a crime or fraud;
(3) a client insists upon pursuing an objective that the lawyer considers repugnant or imprudent;
(4) the client fails substantially to fulfil an obligation to the lawyer regarding the lawyer's services and has been given reasonable warning that the lawyer will withdraw unless the obligation is fulfilled;
(5) the representation will result in an unreasonable financial burden on the lawyer or has been rendered unreasonably difficult by the client; or
(6) other good cause for withdrawal exists.
(c) If permission for withdrawal from employment is required by the rules of a tribunal, a lawyer shall not withdraw from employment in a proceeding before that tribunal without its permission.
(d) Upon termination of representation, a lawyer shall take steps to the extent reasonably practicable to protect a client's interests, such as giving reasonable notice to the client, allowing time for employment of other counsel, surrendering papers and property to which the client is entitled, and refunding any advance payment of fee that has not been earned.
(e) A lawyer must make available to a former client, within a reasonable time following the client's request for his or her file, the following:
(1) all papers, documents, and other materials the client supplied to the lawyer. The lawyer may at his or her own expense retain copies of any such materials.
(2) all pleadings and other papers filed with or by the court or served by or upon any party. The client may be required to pay any copying charge consistent with the lawyer's actual cost for these materials, unless the client has already paid for such materials.
(3) all investigatory or discovery documents for which the client has paid the lawyer's out-of-pocket costs, including but not limited to medical records, photographs, tapes, disks, investigative reports, expert reports, depositions, and demonstrative evidence. The lawyer may at his or her own expense retain copies of any such materials.
(4) if the lawyer and the client have not entered into a contingent fee agreement, the client is entitled only to that portion of the lawyer's work product (as defined in subparagraph (6) below) for which the client has paid.
(5) if the lawyer and the client have entered into a contingent fee agreement, the lawyer must provide copies of the lawyer's work product (as defined in subparagraph (6) below). The client may be required to pay any copying charge consistent with the lawyer's actual cost for the copying of these materials.
(6) for purposes of this paragraph (e), work product shall consist of documents and tangible things prepared in the course of the representation of the client by the lawyer or at the lawyer's direction by his or her employee, agent, or consultant, and not described in paragraphs (2) or (3) above. Examples of work product include without limitation legal research, records of witness interviews, reports of negotiations, and correspondence.
(7) notwithstanding anything in this paragraph (e) to the contrary, a lawyer may not refuse, on grounds of nonpayment, to make available materials in the client's file when retention would prejudice the client unfairly.
Adopted June 9, 1997, effective January 1, 1998.
 A lawyer should not accept representation in a matter unless it can be performed competently, promptly, without improper conflict of interest and to completion.
 A lawyer ordinarily must decline or withdraw from representation if the client demands that the lawyer engage in conduct that is illegal or violates the Rules of Professional Conduct or other law. The lawyer is not obliged to decline or withdraw simply because the client suggests such a course of conduct; a client may make such a suggestion in the hope that a lawyer will not be constrained by a professional obligation. Paragraph (c), taken from DR 2-110(A)(1) of the Code of Professional Conduct, has been substituted for ABA Model Rule 1.16(c) because it better states the principle of the need to obtain leave to withdraw.
 When a lawyer has been appointed to represent a client, withdrawal ordinarily requires approval of the appointing authority. See also Rule 6.2.
 A client has a right to discharge a lawyer at any time, with or without cause, subject to liability for payment for the lawyer's services. Where future dispute about the withdrawal may be anticipated, it may be advisable to prepare a written statement reciting the circumstances.
 An appointed lawyer should advise a client seeking to discharge the appointed lawyer of the consequences of such an action, including the possibility that the client may be required to proceed pro se.
 If the client is mentally incompetent, the client may lack the legal capacity to discharge the lawyer, and in any event the discharge may be seriously adverse to the client's interests. The lawyer should make special effort to help the client consider the consequences under the provisions of Rule 1.14.
 A lawyer may withdraw from representation in some circumstances. The lawyer has the option to withdraw if it can be accomplished without material adverse effect on the client's interests. Withdrawal is also justified if the client persists in a course of action that the lawyer reasonably believes is criminal or fraudulent, for a lawyer is not required to be associated with such conduct even if the lawyer does not further it. Withdrawal is also permitted if the lawyer's services were misused in the past even if that would materially prejudice the client. The lawyer also may withdraw where the client insists on a repugnant or imprudent objective.
 A lawyer may withdraw if the client refuses to abide by the terms of an agreement relating to the representation, such as an agreement concerning fees or court costs or an agreement limiting the objectives of the representation.
Assisting the Client upon Withdrawal
 Even if the lawyer has been unfairly discharged by the client, a lawyer must take all reasonable steps to mitigate the consequences to the client. Whether or not a lawyer for an organization may under certain unusual circumstances have a legal obligation to the organization after withdrawing or being discharged by the organization's highest authority is beyond the scope of these Rules.
 Paragraph (e) preserves from DR 2-110(A)(4) detailed obligations that a lawyer has to make materials available to a former client.
