Changing firms and taking the archive

The change is decided in an afternoon and the handover takes months. Whatever you do not request before announcing it costs double after.

Updated on 13/08/2026

The decision to switch is usually taken quickly and for reasons that are not documentary: price, service, one error too many. The handover, by contrast, is slow, quiet work that starts badly if done in the wrong order — **and the wrong order is announcing first and requesting afterwards**.

The order that works

  1. 1

    Request a copy of what they hold of yours, before saying anything

    It is a normal request from an active client, and is treated as such.

  2. 2

    Check what is missing against your index

    If you have no index, that is the first job.

  3. 3

    And only then announce the change

    With the copy already in your house, the handover stops being leverage.

  4. 4

    Put the formal handover in writing

    What is delivered, in what format and when.

Important

**Requesting your documentation while still a client is not a manoeuvre: it is elementary prudence, and the whole sector knows it.** After the notice, the same request competes with the diary of someone who has just lost a client. It is not bad faith —it is priority— but the result is the same: weeks of delay precisely when the new adviser needs everything to start.

What to ask for, and it is not «everything»

WhatWhy it matters
What was filed in your name, by yearIt is what will be demanded of you
The original documents you providedThey are yours and sometimes there is no copy
The calculations or criteria they appliedWithout them the new adviser starts from zero
**And in what format you get it****A box of paper is not a handover**

Watch out

What is most often lost in a switch is not documents: **it is the reasoning**. Why something was done a particular way, what was agreed at the time with an authority, what is peculiar about your case. That lives in the head of whoever handled you and is in no folder. A one-hour meeting between outgoing and incoming adviser is worth more than half the archive — and it must be requested while the relationship is still cordial.

Worth knowing

What a professional must hand over on ending an engagement, within what period and what may be withheld depends on professional rules and on what was agreed. **If the handover becomes difficult, your new adviser or professional body settles that**; here we explain the order that avoids reaching that point.

Can they withhold my documentation?

It depends on professional rules and what was agreed. Ask before it becomes a problem.

What format should I ask for?

One that can be used. A box of paper with no index is half a handover.

Is a handover meeting worth it?

It is the most easily lost and cheapest thing to preserve. Ask for it.
