Knowing who you are working with

In some activities, taking on a client means checking who they really are — and doing it before you start.

Updated on 13/08/2026

A new client arrives with an urgent job. Documentation gets requested «as we go», because nobody wants to open by raising objections. Three months later, when things get complicated, it turns out all that is known about the client is a trading name — and that whoever was signing did not hold the authority they claimed.

Beneficial owner

The natural person actually behind it. Not the director who signs nor the company on the contract: whoever controls. Identifying them is precisely where a superficial check parts company with a real one.

The four steps, and where people skip

StepWhat is checkedThe shortcut taken
Who they areIdentity of the person or companyAccepting whatever the introduction email says
Who really controlsThe beneficial owner behind the companySkipped once the structure has two levels
Who may signCurrent powers and their scopeThe power is read, its currency is not
Where the money comes fromSource of funds, depending on the caseAssumed, because the client «is known to us»

Important

The rule that avoids 90 % of the trouble is about timing, not content: **the check happens BEFORE starting, not alongside**. Once you have worked for a month, saying no is an expensive decision, which is why it almost never gets taken. Starting without checking is not gaining time: it is giving up the only window in which saying no is cheap.

What makes the file useful later

  1. 1

    Keep what you checked and WHEN

    Undated, you cannot show it happened before starting.

  2. 2

    Note what you could not check, and why

    An explained gap is defensible; a silent one is not.

  3. 3

    Review whenever something changes

    Change of director, of ownership, of activity or of how they pay.

  4. 4

    And look again periodically even when nothing changes

    A four-year-old check describes a four-year-old company.

Watch out

The most repeated blind spot is the long-standing client: **reviews are run on new clients and never on old ones**. The file of the client of eight years holds day-one documentation, and in those eight years they have changed owner, sector and billing country. A periodic sweep of the old portfolio turns up more than ten checks on new arrivals — and it is precisely the one nobody schedules, because there is nobody waiting on the other end of the phone.

When something does not add up

Worth knowing

Who counts as an obliged entity, which checks correspond to each case, when there is a duty to report and what may NOT be told to the client is set by anti-money-laundering rules and their implementation. **Your adviser or compliance officer settles that, and it is not improvised**; here we cover the documentary side: check first, keep it dated, and look again.

Does this apply to my activity?

It depends on sector and transaction. That is exactly the question to take to your adviser beforehand.

How often do I review long-standing clients?

On a frequency you set, and whenever something relevant changes.

Can I start while completing the documentation?

It is the most expensive decision available. If taken, take it in writing and with a deadline.
