The Hidden Data Risk in Firm-to-Firm Attorney Moves

The Moment a Departure Happens

When a partner announces a departure, the operational impact begins immediately. Questions start appearing across the organization within hours. Clients may ask who will now own their matters, IT begins reviewing document management access, and information governance teams check ethical walls and matter assignments.

In many firms, the response to these events is still largely manual. A ticket is opened. Permissions are reviewed one system at a time. Files may be exported to shared drives or packaged into PST files from email accounts. Someone attempts to double-check which documents might be relevant before anything is moved or retained.

Under time pressure, these steps can turn into a scramble. What should be a structured transition instead becomes a series of disconnected actions taken by department teams trying to respond quickly.

Where the Real Risk Appears 

Attorney departures are not simply about moving files from one place to another. They involve chain of custody, client confidentiality, ethical wall enforcement, and the ability to demonstrate how information was handled during the transition.

Many of the risks appear in places firms do not always immediately see. Documents may exist in personal cloud storage, OneDrive, or Box folders outside the document management system, draft agreements not yet saved to a matter workspace, or client communications stored in mailbox folders. Metadata associated with those files can be lost if transfers are handled improperly.

When the process is manual and inconsistent, it becomes difficult to verify later what actually happened. Files may be copied but not validated, permissions may not be fully reviewed, and there may be no reliable record of how information was evaluated during the transition.

Turning Firm-to-Firm Movement into a Workflow 

Firms that manage these transitions effectively approach attorney departures as governed operational workflows rather than isolated events. Instead of reacting to each departure independently, they define trigger points that initiate the process the moment a resignation or transition is confirmed.

From there, standardized workflows guide how matters are reviewed, how files are evaluated, and how permissions are validated before any data is moved. Storage systems associated with the attorney can be identified and checked, ensuring documents outside the primary document management systems are not overlooked. Each step of the process can be logged so that the firm has a clear record of how the transition was handled.

By structuring the process in this way, lateral movement becomes something that can be managed consistently rather than handled differently each time it occurs.

Building Operational Maturity Around Mobility 

Lateral movement is unlikely to slow down. As firms continue to compete for experienced attorneys and practice groups, firm-to-firm transitions will remain a regular operational challenge.

Treating these events as governed workflows rather than manual coordination efforts allows firms to reduce risk, preserve client trust, and maintain clear visibility into how sensitive information is handled during attorney departures.
