Rules of Professional Conduct: Rule 1.16--Declining or Terminating Representation
(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) The client fails substantially to fulfill 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;
(4) The representation will result in an unreasonable financial burden on the lawyer or obdurate or vexatious conduct on the part of the client has rendered the representation unreasonably difficult;
(5) The lawyer believes in good faith, in a proceeding before a tribunal, that the tribunal will find the existence of other good cause for withdrawal.
(c) A lawyer must comply with applicable law requiring notice to or permission of a tribunal when terminating a representation. When ordered to do so by a tribunal, a lawyer shall continue representation notwithstanding good cause for terminating the representation.
(d) In connection with any termination of representation, a lawyer shall take timely 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 or expense that has not been earned or incurred. The lawyer may retain papers relating to the client to the extent permitted by Rule 1.8(i).
 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.
 When a lawyer has been appointed to represent a client, withdrawal ordinarily requires approval of the appointing authority. See also Rule 6.2. Difficulty may be encountered if withdrawal is based on the client’s demand that the lawyer engage in unprofessional conduct. The court may wish an explanation for the withdrawal, while the lawyer may be bound to keep confidential the facts that would constitute such an explanation. The lawyer’s statement that irreconcilable differences between the lawyer and client require termination of the representation ordinarily should be accepted as sufficient.
 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.
 Whether a client can discharge appointed counsel may depend on applicable law. A client seeking to do so should be given a full explanation of the consequences. These consequences may include a decision by the appointing authority that appointment of successor counsel is unjustified, thus requiring the client to proceed pro se.
 If the client has diminished capacity, 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 a special effort to help the client consider the consequences and, in an extreme case, may initiate proceedings for the appointment of a surrogate decision-maker or similar protection of the client.SeeRule 1.14.
 A lawyer may withdraw from representation in some circumstances. The lawyer has the option to withdraw if the withdrawal 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.
 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 the timely payment of the lawyer’s fees, court costs or other out-of-pocket expenses of the representation, 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. The lawyer may retain papers as security for a fee only to the extent permitted by Rule 1.8(i).
Compliance With Requirements of a Tribunal
 Paragraph (c) reflects the possibility that a lawyer may, by appearing before a tribunal, become subject to the tribunal’s power in some circumstances to prevent a withdrawal that would otherwise be proper. Paragraph (c) requires the lawyer who is ordered to continue a representation before a tribunal to do so. However, paragraph (c) is not intended to prevent the lawyer from challenging the tribunal’s order as beyond its jurisdiction, arbitrary, or otherwise improper while, in the interim, continuing the representation.
Return of Client’s Property or Money
 Paragraph (d) requires a lawyer to make timely return to the client of any property or money “to which the client is entitled.” Where a lawyer holds property or money of a client at the termination of a representation and there is a dispute concerning the distribution of such property or money – whether such dispute is between the lawyer and a client, the lawyer and another lawyer who is owed a fee in the matter, or between either the lawyer or the client and a third party – the lawyer must segregate the disputed portion of such property or money, hold that property or money in trust as required by Rule 1.15, and promptly distribute any undisputed amounts. See Rule 1.15 and Comments  and  thereto; see In re Haar, 667 A.2d 1350 (D.C. 1995), 698 A.2d 412 (D.C. 1997). Notwithstanding the foregoing, where a lawyer has a valid lien covering undisputed amounts of property or money, the lawyer may continue to hold such property or money to the extent permitted by the substantive law governing the lien asserted. See generally Rules 1.8, 1.15(b).
