Traceability and compliance

When someone asks you to delete their data

What can be deleted, what must be kept, and why that is not a contradiction.

Updated on 13/08/2026

The request arrives and the instinctive reaction is one of two: delete everything quickly, or delete nothing out of fear. Both are wrong. The right answer separates what must be kept from what there was no reason to hold.

The three categories

What it isWhat to do
Data you hold with no current reasonDelete it. It is what the request asks for and what you should not have
Data with a legal retention obligationKeep it, and explain why and until when
Evidence of a signature or deliveryKeep it while the document has effects

Important

A signature is not deleted. This is not a technical limitation: a signature that could be made to disappear at the signer's request would prove nothing, and then no signed document would hold. That gets explained; it is not negotiated.

What to do, in order

  1. 1

    Check who is asking

    That it is the person the data concerns. An erasure request is also an impersonation vector.

  2. 2

    Talk to whoever handles data protection

    Someone in your company is responsible for this, even if the title says otherwise. There are deadlines.

  3. 3

    Separate the three categories

    With the retention policy in front of you, not from memory.

  4. 4

    Reply with reasons

    What was deleted, what is kept and why. A reasoned reply closes nearly every request.

Watch out

If there is a live claim or litigation touching that data, delete nothing without checking. Deleting material relevant to open proceedings is a bigger problem than the one you were solving.

Worth knowing

The best way to answer these requests well is not to have kept too much. A retention policy genuinely applied turns this into a ten-minute task.

Is this legal advice?

No. It is the practical criterion; the specific deadlines and duties come from your adviser.

How long do I have to respond?

There are legal deadlines and they are short. Which is why step one is telling the right person.

Is my deletion recorded?

Yes, and that helps: it is what shows you honoured the request.
