The Exit, Litigated: What Firms Actually Do When Advisors Resign in 2026

The biggest breakaway in history, $129 billion out of Merrill, was met with a raiding lawsuit, a TRO request, and an arbitration fight. The TRO was denied, the arbitration push failed, and the RIA launched anyway. What departure enforcement actually looks like in 2026: who sues, what courts are granting, what the Broker Protocol still covers, and what the record says about how prepared exits fare.

Advisor Departure Litigation in 2026: TROs, Raiding Suits, and the Broker Protocol

The short answer: the best evidence on what firms actually do to departing advisors in 2026 is the biggest test case ever run. When roughly 120 people left Merrill's $129 billion institutional advisory business to launch OpenArc, Merrill answered with the full playbook: a raiding suit naming Schwab and Dynasty, a TRO request, and an arbitration campaign. The TRO was denied in October 2025, the arbitration push was rejected by a federal judge in July 2026, and the firm launched and operates. That is not the whole story, because TROs are still granted where exits are sloppy or engineered to harm, and the Protocol map still splits the industry into two different legal worlds. But the pattern of the last twelve months is unmistakable: prepared exits keep prevailing, and the enforcement machine works best against people who gave it something to work with.

The test case the industry was waiting for

Every departing advisor's real question about litigation is some version of: if my firm truly wanted to stop me, could it? The last year supplied the closest thing to a definitive answer the industry will ever get, because a firm with maximal motivation and unlimited legal budget tried, against the largest breakaway ever recorded.

The facts, from the court record and trade coverage: in September 2025, about 120 of the 170 employees in Merrill's Global Corporate and Institutional Advisory Services business, roughly $129 billion in client assets, resigned to launch OpenArc, an Atlanta RIA built on Dynasty Financial Partners' platform and custodying at Charles Schwab. Merrill filed a raiding suit in Georgia federal court naming Schwab, Dynasty, and twelve former employees, and sought a temporary restraining order to bar the departed advisors from using its information or soliciting its clients.

The judge denied the TRO in October 2025, and OpenArc launched. The case then detoured into a dispute about where the fight would even happen: Merrill argued the parties had agreed to FINRA arbitration, and in July 2026 a federal judge rejected that too, finding Dynasty had never consented, with a ruling blunt enough that trade coverage quoted it directly. InvestmentNews' assessment of the aftermath ran under a headline about the loss shifting the balance of power toward breakaways.

Read carefully, the case teaches three things. Enforcement at full strength is survivable by a prepared team. Courts want evidence of actual misconduct, not the fact of a departure, however large. And naming the destination firm and platform in a raiding theory, the most aggressive move available, subjected the claims to exactly the scrutiny they could not withstand.

What the machine still wins

It would be malpractice to end the story there, because the same twelve months supplied the counterexample. In May 2026, a TRO was granted in a mass-departure case where, per the employer's filings, nearly 300 employees across the country resigned without notice in a coordinated move to a competitor, about 40 from a single office. That case comes from the insurance brokerage world rather than wealth management, but judges do not read industry labels; they read fact patterns, and the fact pattern that keeps losing for advisors is the same one that lost there: coordination that reads as engineered harm, departures timed to cripple, and evidence that information moved before resignations did.

The stable pattern across the recent record: TROs are granted on evidence and denied on indignation. Client data taken on the way out, solicitation before resignation, and choreographed mass exits give a court something to restrain. A clean, counseled resignation gives it nothing, which is the practical meaning of the OpenArc denial. The variable most within an advisor's control is the cleanliness of the exit itself.

The other thing the machine reliably wins is the economics of fear. Demand letters vastly outnumber filed cases, and filed cases vastly outnumber verdicts, because the letter is cheap and the suit is not. An advisor who has prepared with counsel reads the letter as the negotiating document it usually is. An advisor who has not reads it as a verdict, which is precisely its purpose.

The map that decides which game you are playing

Before any of the above applies, one fact sorts every departure into one of two legal worlds: whether both firms are Broker Protocol members on the day of resignation.

Roughly 2,600 firms remain signatories in 2026, including Merrill, Wells Fargo Advisors, Raymond James in both channels, RBC, and Stifel. UBS and Morgan Stanley both exited in 2017 and enforce restrictive covenants instead, a difference that shows up in the movement data every quarter, and which we map firm by firm in The State of Financial Advisor Movement. Between member firms, an advisor who takes only the Protocol's narrow list of client information, in the prescribed manner, resigns into a largely litigation-proof channel. Outside it, the governing documents are the advisor's own agreements: non-solicits, garden leave, forfeiture provisions, and the rest of the toolkit we broke down in can my firm sue me for leaving, with the Protocol's mechanics covered in our Protocol explainer.

Two Protocol details that recur in the case law: membership must be true on the day of resignation, and firms can withdraw with little notice, so it gets verified at the end of planning, not the beginning. And Protocol protection covers information handling, not conduct; pre-resignation solicitation is unprotected regardless of membership.

Team departures add their own layer, because coordination is legally double-edged: the efficiency that makes a team move work is the same fact pattern a raiding claim is built from. Who leaves, in what order, and what is said between partners beforehand belongs in counsel's choreography, a subject that overlaps with the ownership questions in advisor team splits.

What the pattern means for an advisor weighing a move

Strip the drama and the 2026 landscape reduces to an underwriting problem, which is how both sides actually treat it. Firms litigate hardest where the assets are largest and their contractual hooks are strongest, then settle once the clients have voted with their transfers, because the clients largely follow and everyone's lawyers know it. Advisors get in trouble not because enforcement is inescapable but because they improvised: took files for comfort, told a favorite client early, or coordinated a team exit like a heist instead of a legal process.

The honest conclusion from the year's record is neither "relax" nor "be afraid." It is that preparation has never been worth more, because the gap between prepared and unprepared outcomes has never been wider. The biggest breakaway in history walked through the full enforcement machine because it was built, over months, to withstand exactly that. The exits that ended in restraining orders were built in group chats.

A closing note on scope. This article describes the public litigation record and industry practice; it is not legal advice, it does not evaluate any reader's agreements, and nothing here should be read as guidance to act against an existing employment contract. Any transition should be planned with employment counsel experienced in advisor moves. Winthrop & Co. works alongside that counsel: we run the business side of the transition confidentially, coordinate the sequencing, and the advisor never pays our fee. If you are weighing a move and want the process run the prepared way, request an introduction. Held in strict confidence.

Frequently asked

What legal actions do firms actually take when an advisor resigns?
The realistic menu, roughly in order of frequency: a demand letter reciting the advisor's agreements; a TRO or injunction request in court, aimed at halting solicitation or data use while arbitration gets underway; a FINRA arbitration claim for damages against the advisor; and, in team-scale departures, a raiding suit that may also name the destination firm and its partners, as Merrill's case over the OpenArc departure named Schwab and Dynasty. Most departures draw none of these. The odds rise with the size of the book, the coordination of the exit, and the restrictiveness of the contracts signed.
What happened in the Merrill OpenArc case, and why does it matter?
In September 2025, about 120 of 170 employees of Merrill's $129 billion institutional advisory business left to launch OpenArc, an Atlanta RIA on Dynasty's platform custodying with Schwab. Merrill sued Schwab, Dynasty, and twelve former employees for raiding and sought a temporary restraining order. A federal judge denied the TRO in October 2025, the firm launched, and in July 2026 the court rejected Merrill's attempt to compel Dynasty into FINRA arbitration, finding Dynasty never agreed to arbitrate. It matters because it was a full-strength test of the enforcement playbook against the largest breakaway on record, and the playbook mostly failed. Trade coverage has read it as a shift in leverage toward prepared departures.
Are TROs against departing advisors usually granted?
No, but they are not rare either, and the pattern in the outcomes is instructive. Judges grant TROs when the firm shows concrete evidence: client data taken, solicitation before resignation, coordinated mass exits that look engineered to cripple an office. A 2026 example granted a TRO where hundreds of employees resigned without notice in a coordinated move. Judges deny them when the firm offers little beyond the fact of the departure, as in the OpenArc ruling. The variable most within an advisor's control is the cleanliness of the exit: what was taken, what was said to clients and when, and how closely counsel's choreography was followed.
Does the Broker Protocol still protect departing advisors in 2026?
Yes, for departures between member firms, and the membership map is the first thing to verify. Roughly 2,600 firms remain signatories, including Merrill, Wells Fargo, Raymond James, RBC, and Stifel. UBS and Morgan Stanley both exited in 2017 and enforce restrictive covenants instead. Protocol protection covers a specific, narrow list of client information taken in a specific way, and it only applies when both firms are members on the day of resignation; it is also worth confirming membership close to the exit date, since firms can and do withdraw. A Protocol-eligible move and a non-Protocol move are different legal events requiring different preparation.
Can my firm sue me even if I follow the rules?
Filing is always available to a firm with a grievance and a legal budget, which is why the practical question is not whether a suit can be filed but whether it can succeed and what it costs to defend. A clean exit narrows the firm's theories to ones courts have been rejecting, and the economics of pursuing a meritless case against a departed book rarely work, which is why demand letters vastly outnumber filed cases and settlements vastly outnumber verdicts. The full breakdown of the tools firms use, garden leave, non-solicits, and forfeiture provisions among them, is in our companion guide on whether your firm can sue you for leaving.
What should an advisor do before resigning to avoid litigation?
This article is not legal advice, and the first real answer is to engage employment counsel who works advisor transitions before any irreversible step. The pattern in the 2025 and 2026 outcomes, though, is consistent: exits that prevailed took nothing beyond what the Protocol or their agreements allowed, said nothing to clients before resignation, resigned in the manner counsel choreographed, and documented their compliance. Exits that drew successful enforcement actions had taken data, pre-solicited, or coordinated in ways that read as engineered harm. The difference between the two is preparation measured in months, which is a large part of what a transition consultant and counsel are for.
