Certifying that you said what you said

When what needs proving is not a document but a notice.

Updated on 13/08/2026

Some communications are not documents and still need proving: notice of a cost overrun, notice of a defect, a warning that a deadline will slip. They get disputed just like a contract, and usually with less evidence behind them.

What exactly gets certified

What it does not certify is that the other party agreed. That needs their signature, which is a different and stronger thing.

Notify or get it signed

If what you are communicating...Do this
Is informative and changes nothingNotify; the send record is enough
May have financial consequencesCertify the communication
Modifies what was agreedSend it for signature, not as a notice
The gap between "I told you" and "you accepted" is the whole difference.

Important

Certifying a communication does not replace notification methods required by a contract or a rule. If your contract says communications go through a specific channel, that channel remains mandatory; this is additional evidence, not a shortcut.

Watch out

Certify the text you actually sent, not a summary of what you remember sending. A reconstructed text proves nothing and, if the original turns up and differs, it weakens your position.

Worth knowing

The most useful thing is usually the dullest: certifying, at the time, the email warning about the delay — not the fifty-page report at the end.

Is it the same as recorded delivery?

They are different things and worth asking your adviser about for your case. This proves content and date; recorded delivery adds a postal operator.

Can I certify it days later?

You can, but the certified date is today's. If it matters, do it the same day.

Can the other party check it?

Yes, with no account, on the public verification page.
