Month 0 — the termination
A long-standing adviser’s mandate ended after a strategic disagreement. Counsel issued notices. Corporate records were updated. The relationship was considered closed.
Month 3 — the harmless call
A bank relationship manager telephoned the former adviser to clarify historic ownership. The adviser answered accurately. No one reported the contact because it appeared administrative.
Month 7 — the recovery
A vendor locked a critical account after unusual travel. Support found the former adviser listed as an emergency contact. They confirmed the principal’s identity and the account was restored. Again, the outcome was useful.
Month 11 — the instruction
A staff member received a message from the adviser referring to an urgent legal issue and copied an archive to outside counsel named in the message. The counsel was not appointed. The staff member acted because the adviser still sounded like part of the institution.
What failed
The organisation revoked formal mandate but not recognition. Providers retained old contacts. Staff retained an old mental model. Recovery systems retained a trusted witness. The adviser’s relational authority outlived the legal relationship.
The interruption control
- Maintain an authority inventory that includes recognition by people and providers.
- Send positive replacement instructions, not only termination notices.
- Test former contacts against recovery and exception routes.
- Tell staff which ordinary-looking requests now require independent verification.
- Review six and twelve months after high-authority departures.
The ghost-authority question
Ask each critical provider: “Whose voice, email or relationship could still cause you to act for us?” Compare the answer with the current mandate register. The gap is the population of people who have left on paper but remain inside the operating system.
