The danger was never resigning. Advisors leave firms constantly — Diamond Consultants counted more than eleven thousand experienced advisors changing firms in 2025, up about sixteen percent from the year before. The ones that went badly almost always failed for the same reason: the advisor treated a legal and procedural event as an emotional one, skipping the homework that would have made the day forgettable.
The five things sit in a deliberate order.
Five decisions determine how a resignation goes: the agreement you signed, your firm's Broker Protocol status, your timing, firm property, and the letter itself. The order matters, because each settles a different question. The agreement tells you which rules bind you personally; Protocol status tells you which govern the client information. And the letter — the part everyone dreads — takes about ninety seconds to deliver once the first four are handled.
Read the agreement you actually signed.
Every advisor thinks they remember their contract, and almost no one does. The version in your memory is usually friendlier than the version on file. Look for notice provisions and any garden-leave term, restrictive covenants, the definitions of firm property, and the money leaving puts at risk — unvested deferred compensation and any unforgiven balance on a recruiting note. Agreements also change, so the document that governs your departure is the current one.
What the Protocol permits, and what it forbids.
The Protocol for Broker Recruiting was created in 2004 by Smith Barney, Merrill Lynch, and UBS. Where it applies, it lets a departing advisor take five pieces of client information, only for clients they personally served: name, mailing address, phone number, email address, and account title. That is the complete list.
Take a sixth thing and you are no longer operating under the Protocol's protection at all — which is the fastest way to convert a routine departure into a lawsuit.
The protection is also conditional on procedure. You resign in writing to local branch management and leave a copy of the client information you are taking. There is a two-list nuance that trips people up: the list you take contains only the five fields, while the copy you leave with the branch adds the account numbers — those go to the firm, never with you.
Membership shifts, so nobody assumes coverage.
The Protocol is voluntary. More than two thousand firms are signatories as of the administrator's October 2025 list, but Morgan Stanley withdrew in November 2017, UBS followed that December, and Smith Barney's parent Citigroup exited in January 2018. Two of the three founders are no longer in it, so nobody assumes coverage — you check the current list, for both firms, close to the day you move.
- If both firms are signatories and you follow the procedure, the covered path is routine.
- If either is not a member, your employment agreement governs, and a non-solicit can bind you regardless.
- Firm property is where good people get into trouble — a forwarded spreadsheet, a printed statement, all logged by firm systems.
The letter should be the boring part.
Hand in the letter after your preparation is done and your landing spot can genuinely receive you — not before. No day of the week rescues a resignation that arrives before the destination firm can onboard you, and none of that calendar folklore appears in the Protocol's text. The letter itself is short, professional, and respectful: you are resigning, effective when, and nothing more. No reasons, no grievances, no long goodbye. Settle the five things in order, with a securities attorney involved before the day, and the moment shrinks to a short conversation and a page of paper.
