Leaving Your Firm Cleanly: The Practical and Ethical Playbook

How you leave matters as much as where you go. The legal profession in England and Wales is small, deeply interconnected, and has a long memory. The partners you leave behind today will be on the other side of a transaction next year, sitting on the same Law Society committee in three, and almost certainly referring work to (or away from) you for the rest of your career. Leave well. It compounds.

Read the contract first

Before you do anything else — before you tell a single colleague, before you sign with a platform firm, before you announce on LinkedIn — read your employment contract, partnership deed or members' agreement carefully. Pay attention to: notice period (sometimes longer than you remember), restrictive covenants on solicitation, non-dealing, non-compete, garden leave provisions, holiday accrual, treatment of client files, return of property, confidentiality obligations that survive termination, and any clawback of bonuses or training costs. Take it home. Read it twice. If it's a partnership deed, take independent legal advice — these are not standard documents and they often contain surprises.

Plan the timing

Resign at a moment that respects the firm's rhythm. Don't resign the day before a big trial or completion. Don't resign in the middle of an audit week. Don't resign by email when you could resign in person. Don't resign just before your holiday. None of these are legal requirements; all of them affect how the conversation goes and how the firm chooses to handle the handover.

The conversation itself

Tell your line manager or managing partner first, in person, in private, with a written letter of resignation ready to hand over. Be brief. Be respectful. Don't apologise. Don't over-explain. Don't name the platform firm in the conversation unless asked, and if asked, answer briefly. Don't complain about anyone. Don't list grievances. The conversation should take ten minutes. Anything longer is you trying to justify yourself, which is unnecessary and unhelpful.

Garden leave and notice

Some firms will put you straight on garden leave. Some will work you hard until your last day. Some will be graceful and let you taper. None of these are personal — they are business decisions about protecting client relationships and operational continuity. Whatever the firm decides, respect it. Don't try to negotiate shorter notice unless you have a genuine commercial reason and the firm has options.

Client matters and handover

This is where most disputes start. Be scrupulous. Active files belong to the firm and the clients, not to you. Handover notes should be substantive, in writing, and on the file. Clients should be told of your departure by the firm in the way and at the time the firm chooses, not by you privately. Restrictive covenants on contacting clients are taken seriously by the courts when they are breached in the period covered. The downside risk of getting this wrong — an injunction, a costs order, professional reputation damage — is enormous. The upside of moving quickly is small.

The clients you can talk to — and when

Once you have left and your covenants permit it, you can (and should) tell your professional network about your move. The line between “professional network” and “clients of the firm” is the line that covenants police. People you knew before the firm, referrers who never instructed the firm directly, peers in the profession — fine. People who became clients of the firm during your employment — careful, and depending on your covenants, potentially off-limits for a defined period. If in doubt, ask an employment specialist for an hour of their time.

What to leave behind

All firm property. All firm documents. All firm data. All firm software access. All firm-issued devices. The temptation to keep “just my own contacts list” or “just my old precedents” is the single most common cause of post-departure disputes between solicitors and former firms. Don't. Your contacts are in your head and in LinkedIn already. Your precedents you can rebuild faster than you can defend a misappropriation claim.

The exit interview

Be calm, be polite, be brief. Don't use it to settle scores. Don't use it to deliver a manifesto. Don't use it to negotiate. The exit interview is not the place to be honest in the way you might be over a drink with a trusted friend; it's the place to confirm process and preserve your reputation.

The afterglow

Six months after you leave, send a short note to the people you respected at the old firm. Not a sales pitch. Just “hope you're well, here's how it's going.” Most consultants don't do this. The ones who do find that referrals from former colleagues become one of their better sources of work over the long run. The profession is small. Leave doors open.
