# What is signing evidence

_The record that travels inside the signed document and makes it defensible._

**Responde a:** what is signature evidence · electronic signature audit trail · what information is stored when signing · how to prove someone signed

**Signing evidence** — The set of data recorded during the signing process — sending, opening, identification and signature — that later allows what happened, and when, to be reconstructed.

The signature itself is an instant. The evidence is the path that led to that instant, and it is what answers when someone says "I never signed that".

## What gets recorded

| Moment | What is kept |
| --- | --- |
| Sending | Who it went to, on which channel and when |
| Delivery | Whether it arrived or bounced |
| Opening | When it was opened and from what kind of device |
| Identification | How identity was checked: phone code, certificate, email |
| Signature | The exact instant, with a certified time |

None of those items proves much on its own. Together and in sequence, they force anyone disputing it to explain how all of that happened without them.

> [!IMPORTANT]
> The evidence travels inside the signed copy. If someone sends you only the PDF printed and rescanned, they have lost the evidence: what you hold is a piece of paper that looks like a contract.

**Is my exact location stored?**

Technical access information is recorded, not tracking of the person.

**Can the signer see their own evidence?**

Yes, it travels in the copy they receive.

**Does it hold up in court?**

It is precisely the material a signature is defended with. Its specific weight is for a judge to assess.

## Ejemplos

**A signer denies, two years later, having accepted a clause.**

- The signed copy and its evidence are opened

→ The record shows the code sent to their phone, the opening from that same device and the certified signing time.

**A signer says they never received the document.**

- Checks the send and open evidence

→ It is on record when it was delivered and when it was opened.

**A signature is requested in a procedure and the detail is needed.**

- Provides the signed document with its evidence

→ A complete item is handed over rather than a screenshot.

**Somebody signs from a device other than their usual one.**

- It is recorded where it was opened and signed from

→ The anomaly can be explained rather than suspected.

**Only the final PDF is kept and the context is lost.**

- Keeps the document with its associated evidence

→ The proof is not separated from the document it backs.

**A client asks exactly what is stored about them when signing.**

- Shows them which fields make up the evidence

→ The answer is specific and verifiable.
