The Duty to Be Replaceable: A Contingency File for Small UK Advisory Firms

In a sole practice or a small advisory firm, the principal is often the firm. Clients know the name on the door; they rely on the judgement behind it. That concentration is a strength in relationship terms, but it creates a continuity risk that clients rarely see and firms rarely document. A contingency file is the practical answer. It is also, properly understood, an instrument of client care.

Continuity Is a Client-Care Obligation

Clients instruct a firm on the assumption that the work will continue. They expect deadlines to be met, files to be available and someone to answer when they call. When the principal is suddenly unavailable — through illness, accident, bereavement or another enforced absence — those assumptions are tested. If no one else knows where the file is, which matters are urgent or who has authority to speak to clients, the harm is not merely commercial. It is a failure of care.

Professional bodies increasingly expect firms to have arrangements in place to protect clients if a principal is incapacitated or otherwise unable to act. Whether or not a regulator prescribes a particular format, the duty of care does not disappear when the principal does. A contingency file is the evidence that the firm has thought about the client's position, not just its own.

What the File Is — and What It Is Not

A contingency file is not a will, a data room or a substitute for succession planning. It is a controlled, secure index and authority document that allows a designated deputy to stabilise the firm and protect clients for a defined period. It should be short enough to be used under pressure and specific enough to prevent guesswork. It should also be reviewed, because a contingency file that describes last year's client list is worse than no file at all: it creates false confidence.

The Core Contents

At a minimum, the file should contain:

• A client contact schedule for live matters, including the principal contact, matter reference, critical deadlines and any known vulnerability.
• Key professional contacts: accountant, solicitor, bank, professional indemnity insurer, IT provider, professional body and any relevant regulator.
• File locations, both physical and electronic, with naming conventions and access instructions. Credentials should be held in a secure password manager, not written into the file itself.
• A list of authorities: who may access systems, who may notify clients, who may instruct the bank and who may deal with the regulator or insurer.
• A handover protocol setting out the sequence of actions for the first 24 hours and the first week.
• Pre-approved client notification wording, so that clients receive a calm and accurate message rather than rumour or silence.
• Billing and banking instructions, including work in progress, signatories and payment approvals.

Authority to Notify Clients

Client confidentiality does not prevent contingency planning; it shapes it. Engagement letters can include a clause explaining that, in the event of the principal's unavailability, a named deputy may contact clients about the continuity of their matters. That clause should be drafted carefully and explained plainly. It is not a licence to disclose matter details unnecessarily.

The authority document should name the deputy, define the scope of the role and set out who may communicate with clients. Pre-approved wording helps: it allows the deputy to say that the firm has arrangements in place, that the client's matter is being reviewed and that a named contact will follow up. The message should be accurate, restrained and consistent. Clients do not need a full account of the principal's circumstances; they need to know that their interests are protected.

A Handover Protocol for the First 24 Hours and First Week

A handover protocol should be simple enough to follow when no one is thinking clearly. In the first 24 hours, the deputy should secure premises and systems, locate the contingency file, identify matters with imminent deadlines and contact clients whose work cannot wait. The insurer and professional body should be notified where required. In the first week, the deputy should confirm handling arrangements for each live matter, update clients on who is responsible, review the deadline calendar and record decisions in writing.

The protocol should also identify a second deputy. A contingency plan that depends on one alternative person is only a partial plan. Where appropriate, the principal should introduce the deputy to key clients before any absence occurs. That introduction is not an admission of fragility; it is a demonstration of professionalism.

Testing, Review and Culture

An untested contingency file is a hope, not a control. Firms should review the file annually and after any significant change in clients, personnel or systems. A short tabletop exercise — asking the deputy to locate the file and explain the first three actions — will reveal more than a lengthy policy document. The file should be stored securely, version-controlled and accessible only to those who need it.

For a small firm, the contingency file is a quiet expression of professionalism. It says that clients will not be abandoned if the principal cannot work. It says that the firm takes continuity seriously, even when continuity is inconvenient to plan for. In a market where clients can choose between firms that look similar on paper, that quiet assurance is a meaningful difference.
