# Handing an evidence bundle to an expert

_When what you kept separately has to travel together to a lawyer, an expert or a court, and arrive checkable._

**Responde a:** preparing evidence for an expert · handing documents to a lawyer with validity · sending evidence to a court · keeping the file verifiable

The day comes when what you certified over two years has to leave your organisation as a single bundle. And there the question is no longer whether you have the evidence: it is whether it will arrive in a state where the recipient can check it themselves.

## What the bundle must carry

| Piece | What it is for | What happens if missing |
| --- | --- | --- |
| The original files, untouched | They are what gets checked | Without them there is nothing to verify |
| Each one's seal or record | Fixes content and moment | You are left with a file whose date cannot be proven |
| How to check it, explained | So the recipient does it alone | You have to do it for them, and that counts for less |
| An index of what each item is | So it is understood without calling you | The expert works blind and asks about everything |
| The context: what happened and when | It orders the reading | Each document is read in isolation |

> [!IMPORTANT]
> There is a technical error that ruins whole bundles and is invisible while doing it: **if you convert the file, it stops matching its seal**. Reprinting a PDF, recompressing a photo to save space, exporting from another program or even a plain «save as» can change the file's bytes — and verification runs on those exact bytes, not on what is displayed. The original travels as it is, unoptimised and untouched. If a lighter version is needed for comfortable reading, it goes separately and is labelled a reading copy.

## How to prepare it without spoiling it

1. **Export the whole file, not document by document** — That way each file travels with its record.
2. **Do not open and resave the originals** — Reading them changes nothing; saving them again does.
3. **Include a page on how to check it** — Half a page, with the address where anyone can verify.
4. **And number everything with an index** — Whoever receives it usually does not know your work.

> [!WARNING]
> The detail that buys the most credibility for the least effort: **let the recipient run the check, not you**. A screenshot from you saying everything matches is a screenshot from you. Give them the file and the way to check it, and they verify it in a minute — from then on they are not trusting anyone, they are checking. That difference is exactly what certifying is for.

## What to ask before sending it

**En corto**

- In what format and by what channel they want it: some will not accept links.
- Whether they need something signed by you alongside the bundle.
- And whether they will forward it to a third party, so you know where it ends up.

> [!NOTE]
> What is submitted in proceedings, in what form and under which formal requirements is decided by your lawyer — and it varies by type of proceeding. **Ask before preparing the bundle**; here we explain how to make sure what you hand over is still checkable on arrival.

**Can I send it zipped?**

Yes: compressing does not change the files inside. Converting them does.

**What if they ask for paper?**

Print it, but send the digital original too: paper cannot be verified.

**Should I send the whole history?**

Ask: too much also complicates, and sometimes it is unwise.

## Ejemplos

**A company prepares evidence for an expert and recompresses the photos to fit an email.**

- Sends the originals untouched and attaches a lighter reading copy separately

→ The expert verifies each photo independently, which is what had to be possible.

**A folder of loose files is sent to the expert.**

- Provides the evidence with its references

→ They can verify each item themselves.

**Context about what each document is missing.**

- Adds an index of what is provided

→ The bundle is understood without phone calls.

**Files that were opened and re-saved are handed over.**

- Provides the originals exactly as sealed

→ Verification comes out correct.

**More than necessary is handed over just in case.**

- Selects what belongs to the case

→ No unnecessary information is provided.

**There is no record of what was handed over.**

- Records the bundle and its date

→ The handover is demonstrable afterwards.
