Reg BI and Rule 17a-4 Obligations That Survive an Advisor's Departure: A Compliance Checklist for the Firm Left Behind
When an advisor resigns, the firm they left keeps the recordkeeping obligations tied to everything that advisor did while registered there. Reg BI recommendation records, retail-customer information, Form CRS delivery logs, and business communications all remain the firm's responsibility under books-and-records Rule 17a-4, generally for six years for relationship-summary records and at least three years for communications. Departure does not reset the clock, and the records must stay producible on exam long after the advisor is gone.
Most transition content is written for the advisor leaving or the firm receiving them. This checklist is for the firm on the other side of the door: the broker-dealer or RIA whose advisor just walked, and whose compliance team now owns the records that advisor generated. For M&A and recruiting-loss situations especially, understanding what you must keep, and cannot quietly purge, is a discrete compliance obligation. Confirm specific retention periods against the current rule text and your counsel, since this summarizes the framework rather than restating every provision.
The principle: records belong to the firm, not the advisor
The foundational point is that books and records are firm obligations, not personal ones. An advisor generates records in the course of firm business, and those records stay with the firm when the advisor leaves. The advisor cannot take them, and the firm cannot dispose of them ahead of schedule simply because the person who created them is no longer registered there.
This matters because departures create a natural temptation to clean house. An account moves out, the advisor is gone, and it feels like the associated records go stale. They do not. The retention obligation runs from when each record was created, not from the advisor's tenure. What an advisor may and may not take on the way out (client data under the Broker Protocol, for example) is a separate question with its own five-field limit, covered in our breakdown of what the Broker Protocol covers and what it means for repapering. This checklist is about what the firm must keep.
What survives the departure
Here is what remains the departing firm's obligation after the advisor leaves, and the general retention posture for each:
| Record type | What it covers | Retention posture |
|---|---|---|
| Reg BI recommendation records | Recommendations made to each retail customer and the basis, under Rule 17a-3(a)(35) | Preserve per 17a-4 books-and-records periods |
| Retail-customer information | Information collected from and provided to customers supporting recommendations | Preserve as part of the recommendation record |
| Form CRS delivery records | That the relationship summary was delivered and when | At least six years after creation under amended 17a-4(e)(5) |
| Business communications | Originals received and copies sent relating to firm business | At least three years, first two readily accessible |
| Registration records | The advisor's U4/U5 history and associated filings | Per firm and regulatory retention requirements |
The pattern across every row is the same: creation date starts the clock, and the firm holds the record regardless of the advisor's status.
The departing-firm checklist
Run this list when an advisor resigns so nothing that must be preserved gets lost in the churn of the exit.
- Freeze, do not purge. Suspend any routine deletion tied to the departing advisor's accounts. The retention clock runs from record creation, so recently created records may have years left to run.
- Preserve recommendation records. Ensure the Reg BI recommendation records the advisor generated, and the customer information supporting them, are captured in firm systems and indexed for retrieval.
- Secure communications. Confirm that business communications the advisor sent and received are in the firm's preserved channels, not only in a mailbox that may be deactivated at exit.
- Log the exit communications. Client-facing communications about the departure itself, including any required notices, are records too. Note that recruiting firms have their own obligation to deliver an educational communication to affected customers, detailed in our guide to FINRA Rule 2273.
- Retain registration filings. Keep the U4/U5 record and associated documentation per requirements.
- Confirm accessibility. Verify that everything preserved can be produced promptly on exam, since a record you cannot retrieve is a finding even when it technically exists.
The single most common failure is deactivating an advisor's systems and mailbox at exit without first ensuring the records they held are captured elsewhere. Sequence the offboarding so preservation happens before deactivation.
Why this bites hardest in M&A and recruiting losses
Two scenarios raise the stakes. In an acquisition or tuck-in, the acquiring firm inherits recordkeeping obligations for the books it absorbs, and gaps left by the selling side become the buyer's exam problem. Due diligence should include confirming that the target's Reg BI and 17a-4 records are complete and producible, because you are buying the liability along with the assets.
In a recruiting loss, the firm losing the advisor still owns the historical records even as it loses the revenue. The emotional pull is to move on quickly. The compliance reality is that the obligation lingers for years. Firms that run departures on a repeatable process, rather than improvising each exit, avoid the gaps that surface later. This is where a structured advisor transition platform helps the outbound side as much as the inbound: it creates a consistent record of what happened during the exit rather than leaving it to memory and deactivated accounts.
Where automation reduces the risk
The failure modes here are almost all about capture and retrieval, which is exactly where tooling helps. Extracting and indexing account and customer records with document intelligence means the data survives in a structured, searchable form rather than trapped in an advisor's local files. Automated preservation keeps communications in captured channels regardless of mailbox status. And a consistent process across every departure means the firm is not reinventing offboarding each time an advisor leaves, which is the model consultants apply when they standardize this across many client firms, as with our work supporting transition consultants.
What tooling cannot do is decide your retention schedule or make legal judgments about specific records. Those stay with compliance and counsel. The tooling ensures that when those judgments are made, the underlying records are intact and retrievable.
The bottom line
An advisor's departure ends their registration at your firm. It does not end your obligation to preserve what they created while they were there. Freeze deletion, capture recommendation records and communications before you deactivate anything, retain for the required periods, and keep it all producible. Treat the exit as a preservation event, and the records that survive the departure will not become the finding that outlives it.
Frequently asked questions
Do a firm's recordkeeping obligations end when an advisor leaves? No. Books and records are firm obligations, not the advisor's personal ones. Records the advisor created in the course of firm business stay with the firm after departure, and the retention clock runs from when each record was created, not from the advisor's tenure. The firm cannot dispose of them early because the advisor has gone.
How long must the departing firm keep Reg BI and related records? Reg BI amended Rule 17a-4(e)(5) to require preserving certain records, including relationship summaries, for at least six years after creation. Communications generally must be retained for at least three years, with the first two readily accessible. Confirm the exact period for each record type against the current rule and your compliance calendar.
What is the most common recordkeeping mistake when an advisor departs? Deactivating the advisor's systems and mailbox at exit before confirming their records are captured elsewhere. Because communications and recommendation records may live in that mailbox, deactivating first can destroy or orphan records the firm is still obligated to preserve. Sequence offboarding so preservation happens before deactivation.
Who owns the recordkeeping liability in an acquisition? The acquiring firm inherits recordkeeping obligations for the books it absorbs, so gaps on the selling side become the buyer's exam exposure. Due diligence should confirm that the target's Reg BI and Rule 17a-4 records are complete and producible, since you acquire the liability along with the assets.
Can the advisor take their client and recommendation records with them? The advisor cannot take firm books and records. What a departing advisor may take is limited and governed separately; under the Broker Protocol, for instance, it is a narrow set of client contact fields and nothing more. The firm's underlying recommendation records, communications, and customer information remain firm property subject to the retention rules.
