Leaving a law firm well is a sequence of mechanics: give the notice your own agreement sets, tell clients only after checking what your state's ethics rules say, sort out who keeps the files, and leave the firm's property behind.
None of it is hard to describe; all of it is easy to get wrong in the final weeks.
Here is the sequence, with the rules named and the places to verify them.
How much notice to give
Start with the documents you already signed.
Our research found no single profession-wide notice figure: what sets yours is the employment agreement, offer letter or — for partners — partnership agreement you signed, and firm policies add terms on top.
Read what you signed before you tell anyone you are going.
If the agreement is silent, the honest answer is that the date becomes a judgment call about what your matters and your team need for a clean handoff.
Put the resignation in writing.
A short written resignation does what a hallway conversation cannot: it fixes the leaving date, gives the firm something to plan around, and leaves a clean record.
Address it to the person your agreement or the firm's policies name, keep it brief and professional, and save a copy.
Keep the letter itself to the date and the handoff — where you are going is a separate disclosure decision.
Expect the conversation that follows to be about transition — timing, handoffs, what happens to each active matter.
If the firm responds with a separation agreement, read anything it asks you to agree to about your future practice before signing.
Telling clients: joint notice and ethics
Taking clients when you leave a law firm is, day to day, a communication question.
The client may hear from both the firm and the departing lawyer, and one form that moment can take is the joint notice: a notice the firm and the departing lawyer send to the client together.
Our research could not confirm what, if anything, the ethics rules require of one.
At the national level, the ABA publishes formal ethics opinions on departing lawyers; the ones our research flags are Formal Opinion 99-414 and Formal Opinion 489, both on departing lawyers.
This page does not paraphrase either text, because the research behind it never read them — and a summary that is off by a nuance is worse than none.
Read the opinions directly, and read the rules as your state has adopted them, before any client communication goes out.
Whether your state's rules say what a client notice must contain, when it goes out or who signs it is something our research did not establish.
That is why the verify-first habit matters more here than anywhere else in the process.
State rules govern — confirm before anything goes out
Who gets the files and the clients?
Where the work goes and where the files sit are two different questions.
Who holds or controls a client file after a lawyer departs is a question our research did not settle, and this page will not guess at the answer for your state.
Your state bar can point you to it — ask early, before the last week compresses every decision at once.
One structure has its own rule.
If the exit is a sale rather than a quiet departure — you are selling your practice, or an area of practice, to the firm or to another lawyer — ABA Model Rule 1.17 allows a lawyer or firm to sell or buy a law practice, or an area of practice, including goodwill, when the rule's conditions are met.
As model text, the version your state adopted is the one that governs.
What you should not expect on the way out is a contract that restricts your right to practice afterward.
ABA Model Rule 5.6(a) bars partnership, employment or similar agreements that restrict a lawyer's right to practice after the relationship ends, except agreements about retirement benefits — and states adopt their own versions of the rule.
If a separation agreement asks for a promise about where you will not practice, have counsel check it against your state's version of the rule; our guide to non-competes for lawyers covers that territory in depth.
Fiduciary duties before you leave
Between the resignation and the last day sits the stretch where departures actually go wrong.
Your clients' matters do not pause while you work your notice, and neither should your attention to them.
The practical translation: keep working your active matters to the same standard, promise no client an outcome on who keeps their work, and route every question about files and funds through the transition plan you and the firm agree on.
Two areas deserve particular care in a departure: client confidences and client trust funds.
If your matters touch either, raise the question early and in writing rather than improvising in the final week — neither should be settled from memory after the fact.
The honest limit of this page: the specific duties of a departing lawyer — what happens to files, funds and confidences in the final weeks — are not something this page can state for your state: it works from the model text and general practice, not from your state's version.
Confirm them with your state bar before your last day, not after.
It is a short conversation, and it is the one part of this process that should not run on a career-site summary — including this one.
Exit interviews
If the firm asks for an exit interview, treat it as the short, professional conversation it is meant to be.
Keep the answers about process and specifics rather than personalities: what made the firm run well, what slowed it down, what a successor will need.
You will want this firm's good will, and its lawyers' good memory of you, long after the last day — an exit interview is an inexpensive place to protect both.
It is also the moment to collect your own answers in writing: the date of your final pay, what happens to your benefits, how the firm wants its property returned and who to contact once you are gone.
Ask in the room and confirm by email, so your last week is not spent reconstructing agreements from memory.
If no one asks, do not demand an audience.
A clean handoff, a gracious note to the colleagues you leave behind and a files-and-funds picture your successor can actually use do more for your reputation than any exit meeting.
Where to find attorney jobs
Once you have worked out how to leave a law firm cleanly, the open question is where you are going.
Open attorney jobs are listed on LawFirmHires, and the attorney careers library covers the decisions on both sides of a move — including lateral moves, if the destination is another firm.
Career information, not legal advice. The ethics rules discussed here are adopted state by state — confirm the rules that govern your departure with your state bar, and have employment counsel review any agreement before you sign it.
