What Client Information Can You Take When You Leave a Wirehouse? A Plain-English Guide

Under the Broker Protocol, advisors leaving a wirehouse may take five categories of client information: client name, address, phone number, email address, and account title — and nothing else. That list is exhaustive, not illustrative. Account statements, portfolio holdings, performance data, and any information beyond those five elements must stay with the firm. Non-Protocol advisors face even stricter limits: only publicly available information may be removed.

Why the Rules Around Client Data Are the Most Dangerous Part of Going Independent

Most advisors spend months planning their transition — the BD choice, the tech stack, the client communication strategy. Then they get the data question wrong in the first 48 hours and face a temporary restraining order before they've opened a single account.

The legal framework governing what client information you can take when you leave a wirehouse is controlled by two overlapping systems: the Broker Protocol (a voluntary agreement between member firms) and FINRA Rule 4511, which governs record retention and client data ownership more broadly. Getting these wrong isn't a compliance footnote — it's the difference between a smooth transition and a lawsuit that delays your launch by months.

According to a 2024 review of wirehouse-to-RIA transition disputes by Investment News, the most common legal action against breakaway advisors involves allegations of misappropriating client records — almost always because the advisor took more than the Broker Protocol permits.

Key Takeaway: The safest rule is this — if it isn't explicitly listed in the Broker Protocol (or your firm's specific policy), assume you cannot take it. Every additional piece of data you copy before you resign is potential evidence in a civil action.

What Exactly Is the Broker Protocol, and Does It Apply to You?

The Broker Protocol is a 2004 voluntary agreement — originally signed by Smith Barney, Merrill Lynch, and UBS — that allows advisors moving between member firms to take a narrow set of client information without triggering legal claims. Today, more than 1,800 firms have signed it.

Before you plan your transition, verify: Is your current firm still a member? Several major wirehouses have withdrawn from the Protocol. Morgan Stanley withdrew in 2017. Firms can withdraw at any time, and if they do, the more restrictive non-Protocol rules apply retroactively to your situation.

To check current Protocol membership, consult RIA in a Box, which maintains an updated member list, or ask your compliance attorney.

If your firm is a Protocol member, you may take:

Client name
Client address
Client phone number
Client email address
Account title (e.g., "John Smith Revocable Trust")

That's the complete list. There is no room for interpretation.

If your firm is not a Protocol member, the landscape is much more restrictive. You may only contact clients using information that is publicly available — such as a phone number listed in a public directory. You cannot take any firm records, including CRM exports, account lists, or internally documented contact information.

What You Absolutely Cannot Take — Even If You Think It's "Your" Data

This is where advisors make expensive mistakes. Here is a clear breakdown:

Data Type	Protocol Advisor	Non-Protocol Advisor
Client name, address, phone, email	✅ Permitted	❌ Not permitted
Account title	✅ Permitted	❌ Not permitted
Account number	❌ Not permitted	❌ Not permitted
Portfolio holdings/values	❌ Not permitted	❌ Not permitted
Account statements	❌ Not permitted	❌ Not permitted
Performance reports	❌ Not permitted	❌ Not permitted
Internal notes / CRM entries	❌ Not permitted	❌ Not permitted

The "it's my client" argument doesn't hold in court. The records created on the firm's systems, using the firm's infrastructure, belong to the firm. This is true even if you brought that client to the firm twenty years ago.

According to FINRA Rule 4511, member firms must preserve all records relating to customer accounts for a minimum of six years. This obligation runs with the firm, not the advisor.

How Do You Rebuild Your Book Without the Data?

This is the practical question that follows the legal one. You leave with five data fields per client — no account numbers, no holdings, no performance history. How do you rebuild operational context quickly enough to not lose clients during the transition?

The answer is: client consent combined with automated repapering.

Step 1: Contact clients using permitted information. Reach out using the phone numbers and email addresses you're permitted to take. Most breakaway advisors are surprised by how quickly clients respond when the advisor they trust calls personally.

Step 2: Clients authorize data transfer. Once a client agrees to follow you to your new firm, they complete an Account Transfer Authorization (ATA) or ACATS form. This authorizes the transfer of all account data, including holdings, statements, and transaction history, from the old custodian to the new one. The data comes with the account — legally, because the client authorized it.

Step 3: Repapering happens in parallel. New account forms are generated for all accounts moving to the new custodian. For advisors moving $150M+ in client assets, this repapering volume is where transitions stall — often 300 to 1,000+ account forms across multiple custodians, each with unique requirements.

FastTrackr AI's advisor transition platform automates the repapering workflow — pulling authorized client data from custodians, pre-filling forms with validated data, and eliminating the NIGO rejections that typically delay completions by two to four weeks. Advisors who previously managed transitions manually in 90 days are completing them in 21 days with automated repapering.

What Happens If You Take More Than You're Permitted To?

The firm finds out. This is not hypothetical — it is routine.

Wirehouses use departure monitoring systems that flag unusual CRM queries, mass email downloads, and bulk data exports in the weeks before an advisor resigns. A 2025 report from the Securities Litigation and Consulting Group found that most firms conduct a forensic analysis of departing advisors' digital activity as standard practice.

If unauthorized data removal is found, the firm's legal department typically seeks:

A temporary restraining order preventing you from contacting the clients on the copied list
An injunction requiring you to return or destroy any copied records
Civil damages for any business lost as a result of your unauthorized solicitation

This is why compliance attorneys who specialize in breakaway transitions consistently advise a simple rule: delete everything from personal devices before you resign, and start the transition with only what the Protocol explicitly permits.

Frequently Asked Questions

What client information can I legally take when leaving a wirehouse?

Under the Broker Protocol, advisors may take only five categories: client name, address, phone number, email address, and account title. Account numbers, holdings, statements, and any other records must remain with the firm. If your firm is not a Broker Protocol member, even those five fields may be restricted to publicly available information only.

Does the Broker Protocol still apply to Morgan Stanley advisors?

No. Morgan Stanley withdrew from the Broker Protocol in 2017. Advisors leaving Morgan Stanley face more restrictive rules and cannot take even the five standard Protocol data fields from firm records. They may only contact clients using publicly available information. Consult a transition attorney before resigning from any non-Protocol firm.

Can I take my book of business when I go independent?

You can take your relationships — but not the records. Clients are free to follow you, and once they authorize their accounts to transfer via ACATS, their complete account data moves with them legally. The distinction is between taking data before authorization (prohibited) and receiving it after client authorization (permitted).

How long does the ACATS transfer process take?

Standard ACATS transfers complete in six business days. Non-ACATS transfers (mutual funds, alternative investments, annuities) vary by asset type and custodian — commonly two to six weeks. Total transition timelines for advisors moving $100M+ in assets typically run 45 to 90 days when managed manually, and 21 to 35 days with automated repapering technology.

What should I do if my firm is not a Broker Protocol member?

Retain a securities attorney who specializes in advisor transitions before you resign. Non-Protocol transitions carry significantly higher legal risk, and the approach differs substantially from Protocol transitions — particularly around pre-resignation preparation, client communication timing, and what you can say to clients in the first 24 hours after you resign.

Can I take notes I wrote myself about clients?

No. Notes created in the firm's CRM system, even if you wrote them yourself, belong to the firm. Personal notes written in personal notebooks or personal apps (not the firm's systems) exist in a legal gray area — consult your attorney. The safest approach is to assume all records touching the firm's infrastructure belong to the firm.

How do I rebuild client relationship context after a Protocol transition?

Client consent forms and ACATS transfers bring the account data legally. For the relationship context — investment preferences, risk tolerance, family details — the answer is the first client conversation after the transition. Most advisors find that a 20-minute onboarding call with each client restores the working relationship context faster than they expected.
