What must a firm do when an associate leaves? Client notice and file rules

Start with what the model texts this page can cite actually address.

If the departing associate's new firm screens them from a matter because of a former-client conflict with one of your clients, your client hears from that side: Model Rule 1.10(a)(2)(ii) requires prompt written notice to the affected former client describing the screen, stating that firm's compliance, noting that tribunal review may be available, and agreeing to respond to inquiries.

Comment [9] to the same rule says the notice should describe the screened lawyer's prior representation and go out as soon as practicable after the need for screening becomes apparent.

What your own firm sends is the half our research could not pin to verified text.

The ABA's formal opinions on law-firm departures — Formal Opinions 94-381, 06-444, 99-414 and 489 — and California's Howard v. Babcock decision (1993) are the leads our research map flags on departure clauses, financial disincentives and client notice.

The opinion texts were paywalled or inconsistently archived when we researched, so this page does not summarize their holdings, and no secondhand summary of them is a rule your firm can act on.

Florida Rule 4-5.8 is the state-level lead the same map flags as requiring joint notice to clients when a lawyer departs — also unverified.

Whatever those authorities say, the text your firm must answer to is your state's adopted conduct rules, not the ABA's model text — the framing note below covers why we hedge that.

Read yours, or ask your state bar's ethics counsel, before you decide who sends what and by when.

One framing note, so the citations above are read correctly: the ABA writes the Model Rules as model texts, and our research carries the frame — as an unverified lead — that they bind no one until a state adopts them and that state versions differ in places.

Every model citation on this page is a baseline, not your state's rule.

Practically, the decision in front of you is narrow even where the rule is not: which clients hear from you, who signs the letter, and how fast it goes out.

The client list starts with the matters the departing lawyer worked on materially — pull it from your conflicts system and your docket rather than from memory.

Where your state prescribes what a departure notice says, that text controls and nothing here replaces it.

Where it does not, the letter is a drafting decision — and the way to draft it is around the jobs it has to do.

The first job is factual: who is leaving, when, and which of this client's matters the departing lawyer worked on.

A client who has to guess at scope will call with questions the letter should have answered.

The second job is the client's choice.

State that the client may continue with the firm, continue with the departing lawyer, or place the work elsewhere.

The model rules' own stated reason for banning restrictive covenants, in Comment [1] to Rule 5.6, is that such an agreement limits the lawyer's professional autonomy and the freedom of clients to choose a lawyer — a notice letter that leans on the client works against the second interest, and it reads that way to the client.

The third job is continuity: a working contact at the firm for each matter, the name of the lawyer responsible in the interim, and how to reach the departing lawyer if the client wants to follow them.

Deadlines and court dates do not pause while a client decides, so the letter should make clear that the work continues under a named owner in the meantime.

Have ethics counsel read the draft before it goes out.

Where a state's rule prescribes the notice's content or timing, the prescription governs; where it does not, the wording still travels under your state's conduct rules, and a letter is easier to fix before it ships than after.

Here the honest answer is that our research came up short, and you should plan around that rather than past it.

This page verified no rule text on who holds, releases or copies a client's file when the lawyer who handled it leaves a firm — the kind of question state conduct rules and courts answer, with bar guidance on top.

We will not fill that gap from memory, and your firm should not either: confirm what your state requires with your state bar's ethics counsel before you release, hold or copy any file.

What you can do now is make the file question boring instead of contentious.

Inventory which matters have physical or electronic files the departing lawyer touched.

For each one, decide — and write down — what moves with the lawyer, what stays with the firm, and what gets copied to both, subject to whatever your state's rule actually requires.

Agreeing the process in writing while a departure is cordial is far easier than reconstructing it after a dispute, and file access is a question that gets harder, not easier, once positions harden.

Keep the transition inside the confidentiality the firm already operates under: files and work product should move as part of the agreed process, not through personal drives and forwarding rules set up in the last week of employment.

That is a practical line, not a rule citation — the confidentiality rules themselves are your state's, and they belong on the same list of things to confirm with ethics counsel.

One instinct at a departure is to reach for a restriction — a covenant in the separation agreement that keeps the lawyer from practicing.

The model rules take that tool away.

Rule 5.6(a) bars a lawyer from offering or making "a partnership, shareholders, operating, employment, or other similar type of agreement that restricts the right of a lawyer to practice after termination of the relationship, except an agreement concerning benefits upon retirement," and Rule 5.6(b) bars agreeing to "an agreement in which a restriction on the lawyer's right to practice is part of the settlement of a client controversy."

Comment [1] gives the reason in one sentence: "An agreement restricting the right of lawyers to practice after leaving a firm not only limits their professional autonomy but also limits the freedom of clients to choose a lawyer."

Read that comment as a firm owner: one of the interests it names — the client's freedom to choose a lawyer — is the same choice a well-drafted notice letter leaves open.

A firm that handles notice and coverage well does not need the covenant, and under the model text it could not use one anyway.

The carve-outs are narrow and specific — retirement benefits in the rule's own words, and Comment [3]'s statement that the rule "does not apply to prohibit restrictions that may be included in the terms of the sale of a law practice pursuant to Rule 1.17."

Rule 5.6 non-competes covers those carve-outs, the harder cases our research could not resolve — forfeiture-for-competition clauses and client non-solicits — and what we could and could not verify about the states.

What the firm does control is the employment relationship while it still exists: the departing lawyer remains supervised, remains bound by the firm's confidentiality expectations, and comes off the matters the firm reassigns.

Where supervision duties end and what client contact is appropriate during a notice period are state-rule questions — put your actual arrangement in front of ethics counsel rather than assuming the model baseline covers it.

Coverage is the operational part of a departure, and it starts the day notice lands.

Build the matter list from the conflicts system and the docket.

Put a named owner on every matter the departing lawyer touched before the client letters go out.

Calendar every deadline, filing date and limitation period sitting in that portfolio — transition periods are a window in which dates can get missed.

Then check conflicts before the firm takes on new work adverse to a client who leaves with the departing lawyer.

Model Rule 1.10(b) is the rule for the firm's position after a lawyer leaves: the old firm may act adversely to that lawyer's former client, unless the matter is the same or substantially related to the departed lawyer's work for that client and a remaining lawyer holds material protected information from it.

Those two conditions are the ones to check — run the check per matter, not from the client list in your head.

If the plan is to backfill rather than redistribute, budget the conflicts work that comes with the hire: a lateral can arrive with former-client conflicts of their own, and the screening discipline runs in both directions.

Conflicts checks for lateral hires covers the intake side, and the guides on hiring for your law firm run from the job posting through onboarding.

Treat the exit itself as data.

An associate departure is an expensive prompt for the retention conversation — the better-timed one happens while the lawyer is still yours.

Associate retention covers the levers you still control for the people remaining: pay, workload and the partnership track.
