Insider — departing attorney or staff

The lawyer who left took the client list. Or staff snooped in a high-profile matter.

The lawyer who leaves with a book of business and a copy of the client files, or staff snooping in a high-profile matter. Audit-log review, the conflicts-and-trade-secret overlay, and the ethics dimension (Rules 1.6, 1.9, 5.3 supervision).

The first hour

What to do, in order.

  1. 01

    Disable accounts on the last day — not the next morning.

  2. 02

    Pull DMS download logs, email-export logs, and USB-device logs for the 90 days before departure.

  3. 03

    Inventory devices, including personal devices that had firm email.

  4. 04

    If client files were copied, the client owns the file — coordinate the handoff in writing with both firms.

Key decisions

The questions you'll be asked.

Is it ethics, civil, or both?
Often both. Confidentiality (1.6 / 1.9), supervision (5.1 / 5.3), and trade-secret / restrictive-covenant exposure run on parallel tracks.

Regulatory & ethical hooks

What the rules say.

  • ABA Model Rules 1.6, 1.9, 5.1, 5.3
  • State trade-secret statutes / DTSA

Cited for orientation, not as legal advice. Your firm's ethics counsel and LPL carrier should be consulted on every specific incident.
