Withdrawing From a Representation: A Practical Checklist

Type: Checklist
Jurisdiction: National
Date: 2024-08-18
Topic: Legal Ethics

Getting out of a matter is one of the most dangerous things a lawyer does, because every exit route runs between two cliffs: abandon the client and face discipline and malpractice exposure, or say too much on the way out and breach confidentiality. This checklist walks the withdrawal decision from diagnosis to closed file. It separates mandatory withdrawal under ABA Model Rule 1.16(a) from permissive withdrawal under Rule 1.16(b), works through the client-fraud and client-perjury scenarios that trigger Rule 3.3's remedial duties, and explains the "noisy withdrawal" problem. It then covers the tribunal's permission requirement under Rule 1.16(c), what a motion to withdraw may and may not say, the Rule 1.16(d) duties to protect the client's interests, the entire-file versus end-product split on file ownership, retaining and charging liens, the refund of unearned fees, the disengagement letter, and the malpractice tail. The Model Rules are a model only — the rules that bind you are your own jurisdiction's, and on file ownership and liens the states genuinely disagree.

Withdrawing From a Representation: A Practical Checklist

Taking a case is a decision. Leaving one is a procedure. The lawyers who get disciplined for withdrawal almost never fail because they left — they fail because they left badly: too loudly, too quietly, too late, or with the client's file still in the drawer.

How to use this checklist

Withdrawal is not a single act. It is a sequence: diagnose the ground, confirm the ground is real, decide whether the tribunal must bless it, draft an exit that discloses nothing it does not have to, hand back what belongs to the client, refund what you have not earned, and close the file in a way that will still make sense to a disciplinary counsel or a malpractice defense lawyer three years from now.

Two framing points before you start.

First: the Model Rules are a model. The ABA Model Rules of Professional Conduct bind no one until a jurisdiction adopts them. Nearly every state has adopted some version of Rule 1.16, but the variations are real — and on the two questions lawyers most often get wrong on the way out the door (who owns the file, and whether you may hold it hostage for fees), the states genuinely disagree. Read this checklist for the framework; read your state's rule, comments, and ethics opinions before you act. For the doctrinal foundation, see Legal Ethics and Professional Responsibility: A Comprehensive Guide to the Model Rules.

Second: most withdrawal problems are intake problems. A well-run conflicts system, a clear engagement letter, and an honest case evaluation prevent most of the representations that later have to be escaped. If you are reading this before you have a problem, read Running a Conflicts Check: A Practical Checklist and Evaluating a New Civil Case: A Practical Checklist instead.

Our running example. Dev Alarcón, a partner at the fictional firm Marbury Lane LLP, represents Tessellate Fabrication LLC, a metal shop, as defendant in a commercial breach-of-contract suit. Tessellate is four months behind on fees. Trial is eleven weeks out. And in a prep session, Tessellate's owner has just told Dev that he intends to testify that a key change order was signed before the delivery date — when Dev has seen the metadata showing it was signed three weeks after. We will follow Dev through every phase.

Phase 1 — Diagnose: is withdrawal MANDATORY under Rule 1.16(a)?

[ ] Determine whether continuing the representation would violate the rules of professional conduct or other law — Model Rule 1.16(a)(1).
[ ] Determine whether your physical or mental condition materially impairs your ability to represent the client — Rule 1.16(a)(2).
[ ] Determine whether you have been discharged by the client — Rule 1.16(a)(3). A client may fire a lawyer at any time, with or without cause.
[ ] Check whether a nonwaivable conflict has arisen (Rule 1.7) or a former-client conflict has surfaced (Rule 1.9).
[ ] Check whether your jurisdiction has adopted the ABA's 2023 amendment to Model Rule 1.16(a), which adds a duty to inquire into and assess the facts and circumstances of each representation — at the outset and during it — sufficient to determine whether the lawyer may accept or continue it, and which requires withdrawal where the lawyer knows or reasonably should know the services will be used to commit a crime or fraud. State adoption of this amendment is uneven and still developing; do not assume it is in force where you practice — pull your state's current rule text and any pending amendments before relying on this item.
[ ] If withdrawal is mandatory, note that you have no discretion — but you still must comply with Rule 1.16(c) (tribunal permission) and Rule 1.16(d) (protecting the client).

Why it matters, and the traps. Rule 1.16(a) is not advisory. If it applies, you must go, and "the client will be prejudiced" is not an answer — though it is a reason to move quickly and to structure the exit carefully. The classic trap is treating a mandatory ground as a negotiating position: the lawyer who discovers a nonwaivable conflict and quietly keeps billing while trying to "manage" it has already committed the violation. The second trap is the mirror image: assuming that because the client is difficult, withdrawal is mandatory. Difficulty is a Rule 1.16(b) question, not a Rule 1.16(a) question, and the two paths have very different consequences.

Note the asymmetry in discharge. The client's right to fire you is nearly absolute — Restatement (Third) of the Law Governing Lawyers § 32 states it plainly. Your right to quit is not. Plan accordingly.

Phase 2 — Or is it PERMISSIVE under Rule 1.16(b)? (and the material-adverse-effect limit)

[ ] Identify which Rule 1.16(b) ground you are actually relying on. The Model Rule lists seven:
- [ ] (b)(1) withdrawal can be accomplished without material adverse effect on the client's interests;
- [ ] (b)(2) the client persists in a course of action involving your services that you reasonably believe is criminal or fraudulent;
- [ ] (b)(3) the client has used your services to perpetrate a crime or fraud;
- [ ] (b)(4) the client insists on action you consider repugnant or with which you have a fundamental disagreement;
- [ ] (b)(5) the client substantially fails to fulfill an obligation to you (paying fees is the paradigm) and has been given reasonable warning;
- [ ] (b)(6) the representation will impose an unreasonable financial burden or has been rendered unreasonably difficult by the client;
- [ ] (b)(7) other good cause.
[ ] Recognize the structural point: grounds (b)(2) through (b)(7) do not require the absence of material adverse effect. Only (b)(1) is the "free exit" ground.
[ ] Document the ground in a contemporaneous memo to file, dated, with the facts as you then knew them.
[ ] Before pulling the trigger, consider whether a less drastic remedy exists: a scope limitation under Rule 1.2(c), a fee restructuring, a candid Rule 1.4 conversation, or associating co-counsel.

Why it matters, and the traps. Lawyers routinely misread Rule 1.16(b)(1) as a general good-faith requirement — as if you may never withdraw where the client would be hurt. That is not the structure. Subsection (b)(1) is one independent ground: if you can leave cleanly, you may leave for any reason at all. The other six grounds exist precisely for the situations where leaving will hurt, and the rule tolerates that harm because the alternative is worse.

The real trap is the unstated ground. A lawyer who is actually leaving because the client is a nightmare (b)(6) but writes a motion invoking nonpayment (b)(5) — when the client is in fact only thirty days late — has created a record that will not survive a fee dispute or a bar complaint. Pick the ground that is true.

Dev's diagnosis. Dev has at least three candidate grounds: nonpayment under (b)(5), client insistence on conduct he finds repugnant under (b)(4), and — once the client actually attempts the false testimony — a mandatory ground under 1.16(a)(1), because offering evidence he knows to be false would violate Rule 3.3. Which one he uses will drive everything that follows.

Phase 3 — The client-fraud scenario and "noisy withdrawal"

[ ] Distinguish prospective fraud (the client wants to do it) from completed fraud (the client did it, using your work).
[ ] Confirm you have knowledge, not suspicion. Rule 1.0(f) defines "knows" as actual knowledge, which may be inferred from circumstances. A hunch is not enough; willful blindness is not a defense.
[ ] Counsel the client first. Under Rule 1.2(d) you may not assist a crime or fraud, but you may — and should — discuss the legal consequences of the proposed course and try to dissuade.
[ ] If the client persists, withdraw under Rule 1.16(a)(1) or 1.16(b)(2)–(3).
[ ] Consider whether to give notice of withdrawal and to disaffirm any opinion, certification, or document of yours the third party is relying on — the "noisy withdrawal." ABA Formal Opinion 92-366 addressed exactly this: a lawyer whose work product is being used to further a client fraud may withdraw and may disaffirm the work product.
[ ] Check your jurisdiction's version of Rule 1.6(b)(2) and (b)(3), which permit (not require) disclosure to prevent or to mitigate substantial financial injury from a client crime or fraud in furtherance of which the client used your services. Some states make disclosure mandatory; California, notably, permits confidential-information disclosure only in a far narrower circumstance — to prevent a criminal act likely to result in death or substantial bodily harm (see Cal. Bus. & Prof. Code § 6068(e) and California's Rule 1.6). Do not import the Model Rule into a state that did not adopt it.
[ ] Consider whether a regulatory overlay compels more: securities counsel, for example, face the SEC's up-the-ladder reporting rules under Sarbanes-Oxley § 307 and 17 C.F.R. Part 205.

Why it matters, and the traps. "Noisy withdrawal" is the most misunderstood move in professional responsibility. It does not mean announcing the client's fraud. It means (1) withdrawing, and (2) telling the relying third party that you disaffirm a specific opinion or document — without stating why. The noise is in the disaffirmance, not in a narrative. Lawyers who convert a noisy withdrawal into a confession of the client's conduct breach Rule 1.6 in the act of trying to comply with it.

The second trap is timing. Rule 1.16(b)(2) requires the client to persist — meaning you must have counseled, and the client must have refused. Withdrawing on the first hint, before counseling, forfeits the chance that the client simply does the right thing, which is the outcome the rules actually prefer. For the broader landscape of when a lawyer's advice tips into participation, see White-Collar Crime and Corporate Criminal Liability: A Comprehensive Guide.

Phase 4 — Nonpayment as a ground — and its limits mid-litigation

[ ] Confirm the client's obligation is substantial — not a single late invoice — and is a failure "regarding the lawyer's services."
[ ] Confirm you gave reasonable warning in writing that you would withdraw absent payment, and that a reasonable cure period has run. Rule 1.16(b)(5) requires the warning.
[ ] Confirm your fee is itself reasonable under Rule 1.5 and consistent with your engagement letter. A lawyer withdrawing over an unreasonable fee is in a very poor position.
[ ] Assess prejudice and timing: how close is trial? Is a dispositive-motion deadline pending? Is the client an entity that cannot proceed pro se?
[ ] Recognize that even a valid ground may be overridden by the court under Rule 1.16(c) if withdrawal would disrupt the proceeding.
[ ] Verify trust-account status: any unearned advance still held must be accounted for and refunded. See Client Trust Accounting and IOLTA Compliance: A Practical Checklist.

Why it matters, and the traps. Nonpayment is the most common ground and the one courts scrutinize most skeptically on the eve of trial. Judges know that a lawyer who takes the case, does the discovery, learns the file, and then leaves when the money runs out has left the client structurally worse off than a lawyer who never appeared. Expect a court to say some version of: you knew the client's finances when you took the case; you may not extract yourself at the moment your departure costs the most.

A specific hazard for entity clients: a corporation, LLC, or partnership generally cannot appear pro se in federal court. Rowland v. California Men's Colony, 506 U.S. 194 (1993), held that the federal in forma pauperis statute's reference to a "person" does not reach artificial entities, and its reasoning rests on the long-standing rule that a corporation may appear in federal court only through licensed counsel. Whether and how that rule applies in a given state court, and what relief a court will grant an entity suddenly left unrepresented, is a matter of that forum's law — check it. Practically, this means a motion to withdraw from an entity client on the eve of trial may leave the entity facing default — and courts will often deny the motion, or condition it on successor counsel appearing first.

Dev's problem. Tessellate is an LLC. If Marbury Lane withdraws and no one replaces it, Tessellate cannot defend itself. That fact alone will shape the court's ruling — and it is why Dev's motion needs to do more than complain about the bill.

Phase 5 — Tribunal permission: Rule 1.16(c) and the motion to withdraw

[ ] Read Rule 1.16(c): you must comply with applicable law requiring notice to or permission of a tribunal, and if ordered to continue, you must continue notwithstanding good cause to withdraw.
[ ] Read the local rule. Most federal district courts and most state trial courts require leave of court once counsel has appeared, and many prescribe the form, the notice to the client, and the service requirements.
[ ] Check whether the court requires that successor counsel appear or that the client consent, and whether a substitution stipulation is available (which is almost always cleaner than a contested motion).
[ ] Confirm whether an evidentiary hearing or in camera submission is contemplated.
[ ] Calendar every deadline that will fall in the gap, and disclose them in the motion.
[ ] Serve the client with the motion and, where required, an advisement of the consequences of proceeding without counsel.

Why it matters, and the traps. Rule 1.16(c)'s last sentence is the one that surprises people: the court can make you stay. Ethical good cause is not a right of exit from a pending case. If the court denies your motion, you must continue to represent the client competently and diligently — and you may not sandbag the representation in protest. A lawyer who is ordered to stay and then under-performs has traded a withdrawal problem for a Rule 1.1 and 1.3 problem, which is far worse.

The practical lesson is to move early. A motion filed six months out is a scheduling inconvenience; the same motion filed three weeks before trial is a continuance request in disguise, and it will be treated as one. For the mechanics of motion practice in federal court, see Federal Civil Litigation Filings: A Comprehensive Guide from Complaint to Appeal and The Civil Pretrial Toolkit: From Pleadings to Summary Judgment.

Phase 6 — What to SAY in the motion: withdraw without breaching confidentiality

[ ] Start from the presumption that the motion says as little as possible.
[ ] Use the Rule 1.16 Comment [3] formulation: a statement that "professional considerations require termination of the representation" ordinarily should be accepted by the tribunal as sufficient.
[ ] For nonpayment, consult ABA Formal Opinion 476 (2016), which addresses precisely how much a lawyer may reveal when moving to withdraw for nonpayment in civil litigation: begin with the generic statement; disclose more only if the court demands it; and then only what is reasonably necessary, seeking in camera, sealed, or ex parte treatment.
[ ] If the court presses, object on the record, invoke Rule 1.6, and ask for in camera review before saying anything substantive.
[ ] Never characterize the client's conduct, motives, or credibility in a public filing.
[ ] Do not attach billing records, privileged emails, or the client's admissions as exhibits.
[ ] Remember Rule 1.6(b)(5): the exception permitting disclosure "to establish a claim or defense in a controversy between the lawyer and the client" is for an actual fee action or defense against a client's allegation — it is not a license to explain yourself in a withdrawal motion.

Why it matters, and the traps. This is where good lawyers get hurt. The instinct, when a judge asks "why?", is to answer fully. But your obligation runs to the client, and the client's confidences do not evaporate because a judge is impatient. The disciplined sequence is: generic statement → if pressed, respectful invocation of Rule 1.6 → request for in camera treatment → minimum necessary disclosure under seal. Courts overwhelmingly accept the generic statement; the ones that do not will usually accept the sealed proffer.

A related trap: the unsealed motion that says too little in the wrong way. "Counsel and client have irreconcilable differences regarding the veracity of anticipated testimony" is not a discreet motion — it is an accusation with a fig leaf. It tells the other side, and the court, exactly what your client is about to do. If you would not say it out loud, do not say it in a parenthetical.

Dev's motion. Marbury Lane files a short motion stating that professional considerations require termination of the representation, that the client has been notified in writing, that no deadline falls within the next 45 days, and that the firm will cooperate fully with successor counsel. It says nothing about the change order, the metadata, or the fees. If the court asks for more, Dev will ask to be heard in camera.

Phase 7 — Protect the client's interests: notice, time, deadlines

Rule 1.16(d) is the operative command on the way out: take steps reasonably practicable to protect a client's interests.

[ ] Give the client reasonable notice — in writing, dated, with proof of delivery.
[ ] Allow time to employ other counsel, and say so explicitly.
[ ] Identify every pending deadline — discovery cutoffs, expert disclosures, dispositive-motion dates, trial — in the notice.
[ ] Where necessary, seek a short continuance or an extension so the gap does not swallow a right.
[ ] Offer to speak with successor counsel and to transfer knowledge, not just paper.
[ ] Preserve the litigation hold and confirm in writing that the client's preservation obligations continue after your departure. See Issuing a Litigation Hold and Preserving ESI: A Practical Checklist.
[ ] Do not take any substantive step in the case after withdrawal is granted — and do not stop taking necessary steps before it is.

Why it matters, and the traps. The gap between "I told the client I'm out" and "the court relieved me" is where malpractice lives. Until the order enters, you are still counsel of record, and a default entered during your self-declared retirement is your default. Conversely, the lawyer who keeps litigating after the order is granted has no authority to do so.

The most valuable single item on this list is the deadline inventory. Successor counsel inherits a case, not a calendar. A withdrawal letter that lists — with dates — the expert-disclosure deadline, the summary-judgment deadline, and the pretrial-order deadline is worth more to the client than any amount of apology. See Preparing for Trial: A Pretrial Order and Trial Readiness Checklist for what that inventory should contain.

Phase 8 — The file: what must you hand over?

This is the item on which jurisdictions genuinely differ. Confirm your own state's rule before you refuse to produce anything.

[ ] Identify your jurisdiction's approach:
- [ ] Entire-file approach (majority): the client is entitled to the entire file — pleadings, correspondence, discovery, investigative reports, expert materials, and, in most such states, the lawyer's notes and drafts — subject to narrow exceptions (e.g., internal firm assignment memoranda, conflicts-check materials, documents that would violate a duty to a third person, and in some states internal candid assessments of the lawyer's own performance).
- [ ] End-product approach (minority): the client is entitled to the "end product" — the documents filed, served, or delivered — but the lawyer may retain internal work product, notes, and drafts.
[ ] Consult ABA Formal Opinion 471 (2015), which addresses the surrender of papers and property to a former client and discusses this very split.
[ ] Consult Restatement (Third) of the Law Governing Lawyers § 46, which requires a lawyer to allow a client access to and copies of documents relating to the representation, with limited exceptions.
[ ] Produce the file promptly, in a usable format, including electronic files — email, ESI, case-management data, and metadata where relevant.
[ ] Address who pays for copying: many jurisdictions require the lawyer to bear the cost of producing the original file; charging the client to get their own file back is a frequent grievance.
[ ] Keep a complete copy for yourself, at your own expense, before you send anything.

Why it matters, and the traps. Two traps dominate. The first is the lawyer who, in an end-product state, hands over only the pleadings — and turns out to be in an entire-file state after all. The second is the modern one: the "file" is no longer a redweld. It is a matter workspace, an email archive, a document review database, and a privilege log. If your privilege log is the only map of what was withheld and why, successor counsel needs it. See Building a Privilege Log: A Practical Checklist.

A third, subtler trap: producing the file does not waive the client's privilege — but producing it carelessly, mixed with another client's material, breaches Rule 1.6 as to that other client. Segregate before you send.

Phase 9 — Return unearned fees and client property promptly

[ ] Reconcile the trust ledger for the matter, to the penny.
[ ] Refund any advance payment of fee or expense that has not been earned or incurred — Rule 1.16(d). This is not discretionary and it is not a bargaining chip.
[ ] Deliver the client's property: original documents, exhibits, deposit funds, settlement proceeds, and any tangible items — Rule 1.15(d) requires prompt delivery.
[ ] Provide a full accounting of funds and property held.
[ ] If a portion of the funds is in genuine dispute, hold the disputed portion in trust and distribute the undisputed portion — Rule 1.15(e).
[ ] If your fee was a flat fee, determine what portion was earned. Many jurisdictions treat unearned flat fees as refundable regardless of "nonrefundable" labels; "nonrefundable retainer" language is prohibited or heavily restricted in a number of states.
[ ] Confirm every trust movement is documented. Trust-account irregularities discovered during a withdrawal dispute are the single most reliable route to a suspension.

Why it matters, and the traps. More lawyers are disciplined for what happens to the money on the way out than for the withdrawal itself. The reason is structural: a fee dispute produces an angry client, an angry client files a grievance, and a grievance triggers a trust-account audit. If the ledger is clean, the grievance is about a disagreement. If the ledger is not clean, the grievance is about conversion — and conversion of client funds is close to a strict-liability offense in most states. The full mechanics are in Client Trust Accounting and IOLTA Compliance: A Practical Checklist.

Phase 10 — Retaining and charging liens

Another point of genuine state-law disagreement. Do not assert a lien you have not verified.

[ ] Understand the distinction:
- [ ] A retaining lien is a possessory lien: the lawyer holds the client's file and property until fees are paid.
- [ ] A charging lien is a claim against the proceeds the lawyer helped the client recover.
[ ] Confirm whether your state permits retaining liens at all. Many do, subject to conditions. Others do not — California, for example, does not recognize an attorney's retaining lien over the client file, and California Rule of Professional Conduct 1.16(e)(1) requires a lawyer to release the client's papers and property promptly on termination, regardless of unpaid fees. That is a state rule, not a national one: the point is not that California's answer is yours, but that you must look up your answer before you hold anything back.
[ ] Even where a retaining lien is permitted, confirm the prejudice exception: courts routinely refuse to enforce a retaining lien where withholding the file would materially harm the client, and Rule 1.16(d)'s duty to protect the client's interests often overrides the lien in practice.
[ ] For a charging lien, confirm the statutory or common-law basis, the notice requirements, and whether it must be asserted before judgment or settlement.
[ ] See Restatement (Third) of the Law Governing Lawyers § 43 on lawyer liens, which treats retaining liens as narrowly available and disfavored.
[ ] Ask the harder question: even if you may assert a retaining lien, should you? It converts a fee dispute into a grievance with near-certainty.

Why it matters, and the traps. The retaining lien is the most tempting and the most self-destructive tool in the withdrawal kit. It feels like leverage. In practice it (a) may be unlawful where you sit, (b) will likely be overridden the moment the client shows prejudice, (c) reads to a disciplinary body as holding a client's rights hostage, and (d) hands the client a defense to your fee claim. If you have a real fee claim, pursue it as a fee claim — with a proper demand and, if needed, the fee-arbitration program most bars offer. On building a defensible demand, see Writing an Effective Demand Letter: A Practical Checklist.

Phase 11 — Confidentiality survives — and so do former-client conflicts

[ ] Confirm that Rule 1.6 continues to apply after the representation ends. There is no expiration date on a client confidence.
[ ] Note that the attorney-client privilege survives even the client's death — Swidler & Berlin v. United States, 524 U.S. 399 (1998).
[ ] Load the former client into your conflicts database immediately, with the matter, the adverse parties, and the subject matter. Rule 1.9(a) bars representing a new client in the same or a substantially related matter adverse to a former client without informed consent, confirmed in writing.
[ ] Note Rule 1.9(c): you may not use information relating to the former representation to that client's disadvantage, nor reveal it, except as the Rules otherwise permit.
[ ] Screen laterals and check imputation under Rule 1.10.
[ ] Re-run the conflicts check the moment a new matter touches the former client. See Running a Conflicts Check: A Practical Checklist.

Why it matters, and the traps. The trap is emotional. A withdrawal that ends badly leaves the lawyer feeling wronged — and feeling wronged is precisely the state of mind in which lawyers say too much: to the next client, to a colleague at a bar function, to a judge in an unrelated case, to a reporter. Rule 1.6 does not care that the client behaved badly. If anything, the duty is most tested exactly when it is least deserved.

Phase 12 — The disengagement letter and closing the file

[ ] Send a written disengagement letter. Always. Even for a friendly, mutual, uneventful ending.
[ ] The letter should state:
- [ ] that the representation has ended, and the effective date;
- [ ] the scope of what you did and did not do;
- [ ] any imminent deadlines or statutes of limitations, with dates, and a clear statement that you are not monitoring them;
- [ ] that the client should promptly retain successor counsel;
- [ ] the status of the file and how to obtain it;
- [ ] the final accounting and any refund enclosed;
- [ ] that you are not rendering an opinion on the merits going forward.
[ ] Avoid two extremes: a letter that gives legal advice (which extends the representation) and a letter so terse the client does not realize it is over.
[ ] Close the matter in your systems: stop the clock, close the trust sub-ledger, move the file to the retention schedule, and update the conflicts record.
[ ] Confirm your file-retention period under your state's rule and your own policy, and remember that some materials (originals, wills, trust records) have their own retention rules.

Why it matters, and the traps. The disengagement letter is the cheapest malpractice insurance in the profession. Its central function is to fix a date. Legal malpractice limitations periods in many states run from the end of the representation, or are tolled during it under a continuous-representation doctrine. A client who reasonably believes you are still their lawyer — because you never said otherwise, because you answered one more question, because you never sent the letter — may keep that clock tolled for years.

The single most important line in the letter is the deadline warning. If the client has a statute of limitations running, say so, give the date, and say that you are not protecting it.

Phase 13 — Calendar the malpractice tail

[ ] Identify your state's legal malpractice limitations period (commonly one to three years) and its accrual rule — occurrence, discovery, or damage.
[ ] Identify whether your state applies the continuous-representation doctrine (tolling while the representation continues) and, if so, what ends it.
[ ] Identify whether your state has a statute of repose capping claims regardless of discovery.
[ ] Notify your malpractice carrier if there is any circumstance that could reasonably give rise to a claim. Claims-made policies typically require notice of circumstances, not just claims, and late notice can forfeit coverage.
[ ] Preserve the file, your notes, your time records, and the withdrawal correspondence for the full tail — not just the retention minimum.
[ ] Do not "fix" the file. Adding a memo after the fact, backdating, or cleaning up is the act that turns a defensible malpractice case into an indefensible one.

Why it matters, and the traps. A legal malpractice claim is a negligence claim with an extra element: the "case within a case," in which the client must prove that but for the lawyer's breach, they would have obtained a better result. For the underlying negligence framework, see Tort Law: A Comprehensive Guide to Negligence, Intentional Torts, and Strict Liability. The practical implication for withdrawal is powerful: a lawyer who leaves early, documents the deadlines, hands over a complete file, and refunds unearned fees has made the case-within-a-case nearly impossible to prove. A lawyer who leaves late, silently, and with the file in hand has practically drafted the complaint.

The perjury endgame: how Dev's matter actually resolves

Tessellate's owner does not back down. Dev now faces the scenario that Rule 3.3 was written for.

Counsel first. Dev explains that testifying falsely is perjury; that Dev cannot present it; that if it is presented and Dev learns of its falsity, Dev must take remedial measures including, if necessary, disclosure to the tribunal — Rule 3.3(a)(3) and 3.3(b). He explains that these duties continue to the conclusion of the proceeding and apply even if compliance requires disclosure of information otherwise protected by Rule 1.6 — Rule 3.3(c). This is the rare place where candor to the tribunal overrides confidentiality.
Refuse to offer the evidence. Rule 3.3(a)(3) permits a lawyer to refuse to offer evidence, other than the testimony of a defendant in a criminal matter, that the lawyer reasonably believes is false. In a civil case, this is not a close question.
Constitutional backstop (criminal cases). Nix v. Whiteside, 475 U.S. 157 (1986), held that a criminal defense lawyer who threatened to disclose and refused to assist his client's planned perjury did not render ineffective assistance. A defendant has no right to counsel's help in committing perjury. Tessellate's matter is civil, but the principle frames the whole area.
Withdraw — now mandatory. Because continuing would require Dev to violate Rule 3.3, withdrawal is mandatory under Rule 1.16(a)(1), not merely permissive.
Say nothing in the motion. Dev moves on "professional considerations." The nonpayment stays out of it. The perjury certainly stays out of it.
If the court denies the motion, Dev must stay — and must still refuse to offer the false testimony, must counsel the client, and if the testimony is somehow given, must take remedial measures up to and including disclosure. Denial of withdrawal is not permission to participate.

For the discipline of controlling what a witness does and does not say on the record, see Defending the Witness on the Record: A Practical Checklist.

Common mistakes to avoid

Waiting for the eve of trial. Every ethical ground you had six months ago you still have today — but the court's willingness to let you use it drops toward zero as the trial date approaches.
Over-explaining in a public filing. "Professional considerations require termination" is a complete sentence. ABA Formal Opinion 476 exists because lawyers cannot resist the urge to justify themselves.
Treating denial of the motion as permission to disengage. Ordered to stay means ordered to represent — competently, diligently, and without sulking.
Asserting a retaining lien without checking whether your state permits one. In some states it is unlawful; in most others it is unenforceable the moment the client shows prejudice.
Withholding the file to collect a fee. The most reliable way to convert a collectible receivable into a bar grievance.
Assuming the "end product" rule applies. Most jurisdictions follow the entire-file approach. Assume you owe more than you think, and verify.
Keeping unearned advances. Rule 1.16(d) requires the refund. "Nonrefundable" labels do not survive scrutiny in many states.
Skipping the disengagement letter for a friendly ending. Friendly endings become hostile lawsuits with the passage of time and the running of a limitations period the client blames on you.
Failing to inventory deadlines for the client and successor counsel. This is the omission that most often causes actual harm — and actual harm is what makes a malpractice case.
Confusing a Rule 1.6 exception with a general right to defend your reputation. The self-defense exception in Rule 1.6(b)(5) is for a controversy between lawyer and client, not for a withdrawal motion, a networking dinner, or a review site.
Withdrawing without counseling the client first in the crime-fraud scenario, when Rule 1.16(b)(2) requires persistence — and when counseling often solves the problem outright.
Forgetting the entity-client problem. An LLC or corporation cannot proceed pro se; your withdrawal may be the proximate cause of a default judgment.

The consolidated withdrawal checklist

Diagnose

[ ] Mandatory under Rule 1.16(a)? (violation of law/rules; impairment; discharge)
[ ] Permissive under Rule 1.16(b)? Identify the specific subsection.
[ ] Is a less drastic remedy available (scope limitation, fee restructuring, co-counsel)?
[ ] Document the ground contemporaneously.

If client crime or fraud

[ ] Actual knowledge, not suspicion.
[ ] Counsel the client; require persistence before withdrawing.
[ ] Consider noisy withdrawal: disaffirm the work product, do not narrate the client's conduct.
[ ] Check your state's Rule 1.6(b) — permissive, mandatory, or (California) far narrower.

If nonpayment

[ ] Substantial failure + written warning + cure period.
[ ] Fee itself reasonable under Rule 1.5.
[ ] Assess prejudice and the entity-pro-se problem.

Tribunal

[ ] Read Rule 1.16(c) and the local rule.
[ ] Move early. Prefer a substitution stipulation.
[ ] Motion says "professional considerations." Nothing more unless compelled.
[ ] If pressed, invoke Rule 1.6 and ask for in camera treatment.
[ ] If ordered to continue — continue, fully.

Protect the client (Rule 1.16(d))

[ ] Written notice, dated, with proof of delivery.
[ ] Reasonable time to retain successor counsel.
[ ] Inventory of every pending deadline, with dates.
[ ] Continuation of the litigation hold, confirmed in writing.
[ ] Offer to brief successor counsel.

The file and the money

[ ] Determine entire-file vs end-product in your state (ABA Formal Op. 471; Restatement § 46).
[ ] Produce promptly, in usable form, including ESI.
[ ] Keep your own complete copy first, at your expense.
[ ] Refund all unearned fees and advances (Rule 1.16(d)).
[ ] Deliver client property and a full accounting (Rule 1.15(d)–(e)).
[ ] Hold disputed funds in trust; distribute the undisputed portion.
[ ] Verify whether a retaining lien is even lawful where you sit. Prefer not to assert one.

Close out

[ ] Disengagement letter with effective date, deadlines, and the "I am not monitoring these" warning.
[ ] Former client into the conflicts database (Rules 1.9, 1.10).
[ ] Confidentiality continues indefinitely (Rule 1.6; Swidler & Berlin).
[ ] Notify the malpractice carrier of any reportable circumstance.
[ ] File to the retention schedule. Change nothing after the fact.

Primary authority

Rules of professional conduct (ABA Model Rules — a model only; the binding rules are your jurisdiction's adopted version, and California's differ notably)

Model Rule 1.16 — Declining or Terminating Representation: (a) mandatory withdrawal; (b) permissive withdrawal; (c) tribunal notice/permission and the duty to continue if ordered; (d) duties on termination, including notice, time to retain counsel, surrender of papers and property, and refund of unearned fees. Comment [3] supplies the "professional considerations" formulation.
Model Rule 1.6 — Confidentiality of Information, including the (b)(2)–(b)(3) crime-fraud disclosure exceptions and the (b)(5) self-defense exception. State variation is substantial; some states make disclosure mandatory, and California permits disclosure only to prevent a criminal act likely to result in death or substantial bodily harm (Cal. Bus. & Prof. Code § 6068(e)).
Model Rule 3.3 — Candor Toward the Tribunal: (a)(3) false evidence and remedial measures; (b) criminal or fraudulent conduct related to the proceeding; (c) duties continue to the conclusion of the proceeding and override Rule 1.6.
Model Rule 1.2(d) — a lawyer shall not counsel or assist a client in conduct the lawyer knows is criminal or fraudulent.
Model Rule 1.15 — Safekeeping Property: prompt delivery, accounting, and the treatment of disputed funds.
Model Rule 1.9 — Duties to Former Clients (substantial relationship; use and disclosure of information).
Model Rules 1.4 (communication), 1.5 (fees), 1.10 (imputation).

Cases

Nix v. Whiteside, 475 U.S. 157 (1986) — no Sixth Amendment violation where defense counsel refused to assist the client's planned perjury and threatened disclosure.
Swidler & Berlin v. United States, 524 U.S. 399 (1998) — the attorney-client privilege survives the client's death.
Rowland v. California Men's Colony, 506 U.S. 194 (1993) — artificial entities are not "persons" for purposes of the federal in forma pauperis statute; reflects the rule that entities appear in federal court only through counsel.

Ethics opinions

ABA Formal Opinion 92-366 — withdrawal and disaffirmance of work product where the lawyer's services are being used to further a client fraud ("noisy withdrawal").
ABA Formal Opinion 471 (2015) — the lawyer's obligation to surrender papers and property to a former client; discusses the entire-file and end-product approaches.
ABA Formal Opinion 476 (2016) — confidentiality when moving to withdraw for nonpayment of fees in civil litigation.

Secondary sources

Restatement (Third) of the Law Governing Lawyers §§ 31–33 (termination of authority; discharge and withdrawal; duties on termination), § 43 (lawyer liens), § 46 (documents relating to the representation), § 60 (use and disclosure of client information), § 132 (former-client conflicts).

Accuracy warnings, repeated because these are the ones that bite

The Model Rules are not law. The ABA Model Rules of Professional Conduct bind no lawyer anywhere until the lawyer's licensing jurisdiction adopts them, and adopting jurisdictions change the text. There is no national rule of legal ethics. Every rule number in this checklist is a model rule number; your obligations come from your own state's adopted rules, its comments, its case law, and its ethics opinions. California's rules, in particular, depart from the Model Rules in ways that matter here — on confidentiality exceptions and on the client file above all.
File ownership varies. Most jurisdictions follow the entire-file approach; a minority follow the end-product approach. Confirm yours before you withhold a single page.
Retaining liens vary. Some states permit them subject to conditions; others do not recognize them (California does not recognize a retaining lien over the client file). Confirm before you assert one — and consider not asserting one even where you may.
Ethics rules and opinions change. Rule 1.16 was amended by the ABA in 2023, state adoption of that amendment is still in flux, and ethics opinions are periodically superseded. Treat every authority below as a starting point to verify against the current text, not as a settled answer.

This checklist is general legal information from UpLaw (uplaw.us), not legal advice, and does not create an attorney-client relationship. The ABA Model Rules bind no lawyer until adopted by a jurisdiction, and states differ materially — particularly on client-file ownership, retaining liens, and the confidentiality exceptions. Laws vary by state and change over time; verify current requirements and consult qualified counsel or your state bar's ethics hotline before acting.
