TL;DR
- Most clients do not leave immediately when their advisor changes firms; they wait, watch, and decide based on how the move is handled.
- Retention depends heavily on relationship depth, communication quality, and how much friction is involved in moving accounts.
- Legal restrictions like non-competes and the broker protocol shape what an advisor can say and when, which directly affects how many clients follow.
- Complex households (trusts, UHNW families, business owners) often need more paperwork and more advisor attention to make the transition smoothly.
- The advisors who retain the most clients tend to plan the transition in advance rather than improvise it after the fact.
What actually happens when an advisor changes firms?
When an advisor resigns from one firm and joins another, clients experience a short window of confusion followed by a decision point. In the days after the move becomes public, clients typically get a letter or call from the old firm, a call from the advisor's new team, and sometimes outreach from both sides at once. They are asked to sign new account opening paperwork, review a new fee schedule, and decide whether to complete an ACAT transfer to move their assets.
This is the moment that determines whether a relationship survives the move. Clients are not evaluating the new firm's brand as much as they are evaluating whether their advisor is still reachable, still organized, and still looking out for them. A clean, well-timed handoff feels reassuring. A messy one, where the client hears about the move from a stranger or gets conflicting paperwork, creates doubt at exactly the wrong time.
Firms on both sides know this. That is why departing advisors often work with counsel and a recruiter to plan the sequence of resignation, client notification, and paperwork before the move is announced. Advisors who instead try to handle a move quietly and alone often lose time they cannot get back, since moving a book of business without a lawsuit generally requires careful sequencing, not improvisation.
How many clients really follow an advisor to a new firm?
The honest answer is that it depends on the relationship, not on a fixed industry number. Advisors and recruiters who have run many transitions generally describe a wide range of outcomes: some books move almost entirely intact, while others lose a meaningful share of assets, usually the smaller or more transactional accounts rather than the largest relationships.
The clients most likely to follow are the ones who see the advisor, not the firm, as the source of value. That includes long-tenured clients, clients who were referred in personally by the advisor, and clients with complex planning needs who rely on the advisor's judgment more than any particular platform. The clients most likely to stay behind are newer relationships, clients who were assigned to the advisor rather than recruited by them, and accounts that are mostly passive or transactional.
Firm type also matters. A move between two large brokerages with similar platforms and similar account structures tends to be less disruptive for clients than a move from a wirehouse to an independent RIA, where the client may be asked to sign an entirely new set of custodial and advisory documents. More paperwork generally means more decision points, and more decision points generally means more chances for a client to hesitate or walk away.
What makes clients stay or leave?
Clients stay when the move feels like an upgrade in service and stability, and they leave when it feels like disruption with no clear benefit to them. Several factors show up again and again in transitions that go well.
- Advance notice and a clear story. Clients who hear directly from their advisor, with a simple explanation of why the move happened and what changes for them, tend to stay calmer than clients who find out secondhand.
- Speed of the paperwork process. The longer a client's assets sit in transfer limbo, the more time they have to take a call from a competing advisor at the old firm or elsewhere.
- Continuity of service team. If the same support staff and service model follow the advisor, clients notice the familiarity and it lowers their anxiety about the change.
- Fee and product changes. A move that comes with a materially different fee structure or a narrower product shelf can prompt a client to shop the relationship even if they were otherwise satisfied.
- How the old firm responds. Some firms let a departure go quietly. Others assign a retention team to call every client within hours. An aggressive retention push from the old firm can peel off clients who would have followed with less friction.
None of these factors guarantee a particular outcome for any single move, but they explain why two advisors with similar books can see very different results.
Does the type of client change the outcome?
Yes. Client complexity and account structure change both the odds of retention and the amount of work required to keep the relationship intact. A simple brokerage account can often be transferred with a signature and a short wait. A trust, a business retirement plan, or a household with multiple entities usually needs more documents, more signatures, and sometimes outside counsel.
Ultra-high-net-worth families are a good example. These households often have layered structures, including trusts, family entities, and outside advisors like attorneys and accountants who are used to a certain level of white-glove service. Firms recruiting advisors who truly serve UHNW families know that these clients are not necessarily harder to retain emotionally, since the relationship is often very personal, but they are harder to retain operationally, because the paperwork and account structure take longer to rebuild.
Estate planning-heavy practices see something similar. Clients who came to an advisor specifically for coordinated estate and legacy planning tend to follow that expertise wherever it goes, but the transfer of trust accounts and beneficiary documentation can slow the process down. This is one reason advisors who truly specialize in estate planning often build in extra time for account transfers when planning a move.
Niche practices, such as those serving a single profession, industry, or community, tend to see strong retention because clients often chose the advisor for that specific expertise and have few equivalent alternatives nearby. The same logic applies to firms built around family office style service, where the relationship is closer to a full-time outsourced staff role than a typical brokerage account. In both cases, the depth of the relationship tends to matter more than the size of the firm on the door.
How do non-competes and legal restrictions affect client transitions?
Legal restrictions shape what an advisor can do before and immediately after a move, and that timing has a direct effect on how many clients ultimately follow. Non-solicitation and non-compete agreements can limit whether an advisor is allowed to contact former clients directly, which forces some transitions to rely on public notice or client-initiated contact instead of a personal outreach plan.
The broker protocol, an agreement some firms follow that allows departing advisors to take limited client contact information with them, changes the calculus significantly. A move between two protocol firms generally allows for a faster, more direct client outreach process. A move involving a non-protocol firm, or an RIA outside the protocol framework entirely, usually requires more caution and more reliance on general notice rather than a direct client list.
Because these details vary by contract and by firm, advisors considering a move are generally advised to review their specific agreement well before resigning. Reviewing the details of non-compete clauses before making a move can prevent a transition plan from running into a restriction that was not anticipated.
Large brokerages each have their own patterns and internal processes for handling departures, and advisors leaving a specific firm often benefit from firm-specific guidance. Advisors leaving Morgan Stanley without losing their book or leaving Merrill Lynch with a pre-resignation plan tend to have smoother transitions when they understand these firm-specific processes ahead of time, rather than learning them in the middle of a move.
What can an advisor do to protect client relationships during a move?
The advisors who retain the most clients generally plan the move before it happens rather than reacting to it afterward. A few practices show up consistently among smoother transitions.
- Talk to counsel and, where relevant, a recruiter before resigning, so the legal boundaries around client contact are clear from day one.
- Prepare simple, compliant client communication in advance so there is no gap between the resignation becoming known and the client hearing from the advisor directly.
- Prioritize the most complex accounts first, since trusts, retirement plans, and multi-entity households take the longest to transfer and benefit from an early start.
- Keep the service team as consistent as possible, since familiar staff voices on the phone can reduce client anxiety during the transfer period.
- Be transparent about fee and platform changes rather than letting clients discover differences on their own.
None of this removes all risk. Some clients will always stay behind, whether because of inertia, a relationship with someone else at the old firm, or simple comfort with the familiar paperwork. But the difference between a transition that retains most of a book and one that loses a large share of it usually comes down to preparation, not luck.
Frequently Asked Questions
Do most clients automatically follow their advisor to a new firm?
No. Following is a decision each client makes, not an automatic outcome. Clients with deep, long-standing relationships and complex planning needs are generally more likely to move with the advisor, while newer or more passive accounts are more likely to stay behind.
How long does it take for a client's account to actually transfer?
It varies by account type. Simple brokerage accounts can transfer in days once the paperwork is signed, while trusts, retirement plans, and multi-entity accounts often take longer because they require additional documentation and sometimes outside counsel.
Can a client's old firm try to keep them from moving?
Yes. It is common for the departing firm to reach out to clients quickly with retention offers or reassurances. How aggressively they do this varies by firm and by the size of the account.
Does moving from a wirehouse to an independent RIA affect client retention?
It can. A move to a different type of firm often involves more new paperwork, a different fee structure, and sometimes a different custodian, all of which add friction that a same-type firm move might not have.
What is the biggest factor in whether a client stays with their advisor after a move?
Communication and speed tend to matter most. Clients who hear directly from their advisor early and experience a fast, low-friction paperwork process are generally more likely to stay than clients left to guess what is happening.
