Deciding to change legal representation is usually the straightforward part. What follows – notifying the court, moving the file, settling the final bill, and handing the matter to a new lawyer – is where most practical questions arise. The mechanics differ by jurisdiction and by the type of case, but the broad sequence is fairly consistent across common-law systems. This guide explains what generally happens, using the ABA Model Rules of Professional Conduct in the United States and the SRA Code of Conduct in England and Wales as reference points.
The client can usually change lawyers without giving a reason
In most common-law jurisdictions, the decision to end a lawyer’s instruction belongs to the client. The commentary to Model Rule 1.16 states that 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. Under the rule itself, a lawyer shall withdraw when discharged.
That is a broad right, but it is not unconditional in every setting. Where a lawyer has been appointed by a court, or where a client is funded through legal aid, the appointing authority or the funding rules may shape what happens next. Courts sometimes require a client to show good reason before appointed counsel is replaced. The practical lesson is that the right exists almost everywhere, but the procedure attached to it varies.
The step clients forget: telling the court
When a case is already in litigation, changing lawyers is rarely a private matter between client and counsel. Model Rule 1.16(c) requires a lawyer to comply with any law requiring notice to, or permission of, a tribunal when terminating a representation, and a related comment notes that court approval or notice is often required before an attorney withdraws from a pending case.
In practice, successor counsel typically files a document – variously called a notice of appearance, a notice of substitution, or a change of attorney – while outgoing counsel may need leave to withdraw. Which forms apply depends on the court. What does not change is the calendar: filing deadlines, discovery cut-offs, hearing dates, and any limitation period continue to run throughout the transition. A gap in representation does not pause them.
What actually moves – and what can be held back
When a representation ends, the outgoing lawyer must take reasonable steps to protect the client’s interests. Model Rule 1.16(d) describes those steps: giving reasonable notice, allowing time to engage 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. A comment adds that even where a lawyer has been unfairly discharged, the lawyer must still take all reasonable steps to mitigate the consequences to the client.
The one place the rules leave room is a lawyer’s claim over the file for unpaid fees. In many jurisdictions a lawyer may keep certain papers as security only to the extent permitted by law, an arrangement often described as an attorney’s lien (sometimes a retaining lien over the file, or a charging lien over proceeds). Whether such a lien is available, and how far it extends, is a matter of local law and the terms of the engagement.
| Item | What generally happens | Where the rule is usually found |
|---|---|---|
| Case file (pleadings, correspondence, evidence) | Delivered to the client or successor counsel on request | Model Rule 1.16(d); local court rules |
| Original documents and physical evidence | Returned to the client | Property and ethics rules |
| Unearned portion of an advance fee | Refunded | Model Rule 1.16(d) |
| Internal notes and administrative records | Handling varies; may be retained | Jurisdiction-specific ethics opinions |
| Lien over the file or proceeds for unpaid fees | May be asserted where local law permits | State or national lien law |

Fees, retainers, and the final invoice
How the money is settled depends heavily on how the lawyer was paid. Under an hourly arrangement, the client generally owes for time actually worked and for costs incurred, and any unearned balance of an advance is refunded. Under a flat fee, the position depends on the agreement and on local rules about when a fee is considered earned; if the work is not completed, a refund may be owed. Under a contingency agreement, where the lawyer is paid a percentage of any recovery, a discharged lawyer may still seek payment – often measured by the reasonable value of the work done rather than the original percentage.
Where a fee dispute exists, many jurisdictions offer a formal assessment or arbitration process, and bar associations often run fee-dispute programs. A discharged lawyer may also assert a lien over any eventual settlement or judgment, again subject to local law. These are established mechanisms for resolving who is owed what; the outcome turns on the agreement, the jurisdiction, and whether the discharge was with or without cause.
The commercial architecture around legal claims – funding, fee structures, and how firms are financed – is a subject in its own right, and related business reporting tracks those developments as they shape the wider market.
Confidentiality does not switch off when the lawyer does
A change of representation ends the instruction, not the duty of confidence. Model Rule 1.9(c) prohibits a lawyer who has formerly represented a client from using information relating to the representation to the former client’s disadvantage, or revealing it, except in limited circumstances. The attorney–client privilege belongs to the client, not the lawyer, so it survives the change and can only be waived by the client. In England and Wales, the SRA Code of Conduct similarly requires solicitors to keep the affairs of current and former clients confidential unless disclosure is required or permitted by law or the client consents.
Two routine exceptions are worth knowing. Privilege does not protect communications used to further a crime or fraud, and a lawyer may disclose limited information when pursuing unpaid fees or defending against a claim brought by the client. Beyond those, the incoming lawyer usually requests the file from the outgoing one, and the outgoing lawyer is expected to cooperate with that handover.
A new lawyer may first have to clear conflicts
Before taking over, a successor firm generally runs a conflict check. Model Rule 1.9 restricts a lawyer from representing a new client in the same or a substantially related matter where that person’s interests are materially adverse to a former client, absent informed consent. Rules on imputation can extend that restriction across a firm. Conflict screening is ordinary practice rather than an obstacle, but it can add time to onboarding, particularly in large or highly specialised matters.
A practical sequence for switching
- Put the decision in writing. A dated instruction to the outgoing lawyer creates a clear record of when the representation ended.
- Read the engagement letter. It usually sets out notice terms, fee arrangements, and how a lien, if any, would be handled.
- Ask for an itemised final statement. This shows fees earned, costs incurred, and the balance of any advance.
- Request the file. Ask for it in a usable format and confirm what will be delivered and when.
- Instruct successor counsel. New counsel can often request the file directly and coordinate the handover.
- File any required notice. Substitution or withdrawal documents go to the court where a matter is already pending.
- Confirm every deadline. Share the case calendar so nothing falls between the two firms.
- Reconcile the retainer. Request the refund of any unearned balance and settle the final invoice.
What changes, and what does not
The lawyer changes; the case does not restart. Evidence already filed remains on the record, discovery already exchanged stays in the case, and procedural positions taken by the first firm generally carry forward. A new lawyer inherits the file and the record, and may revisit strategy – but as a matter of continuity rather than a blank slate. For that reason, the most consequential risks in a switch tend to be administrative: a missed deadline, an unfiled notice, or a file that arrives incomplete.
Frequently asked questions
Can a client change lawyers if a retainer has already been paid?
Generally, yes. A retainer does not lock a client into a relationship. The unearned portion of an advance is typically refundable, while the lawyer remains entitled to payment for work actually performed and costs incurred.
Does the court need to be told?
Where a matter is in litigation, notice to the court or permission to withdraw is often required. The exact procedure depends on the court and the stage of the case, and successor counsel usually handles the filing.
Can the outgoing lawyer keep the file until being paid?
Only where local law permits a retaining lien. In many jurisdictions the client is entitled to the file on request, and any fee dispute is resolved separately through an assessment, arbitration, or a claim over proceeds.
Will switching lawyers damage the case?
Not automatically. The record carries over. The practical risk lies in the transition itself – continuity of deadlines and a complete handover are what protect the case.
Is information shared with the first lawyer still confidential?
Yes, generally. Confidentiality and privilege continue after the representation ends and are owed to the client, subject to narrow exceptions such as the crime-fraud exception.
Can a new firm decline the case because of a conflict?
It can. Former-client and imputation rules may prevent a firm from acting in a substantially related, adverse matter, unless the affected former client gives informed consent or effective screening measures apply.
Changing representation is less a break than a handover. The rules exist not to make the change difficult but to ensure that, when it happens, the client’s interests, files, and confidences make the journey intact – while the case itself keeps moving forward on its own schedule.
