# Certifying photos of a site or a delivery

_Making the photo prove when it was taken, which is what always gets disputed._

**Responde a:** certify site photos · prove the condition of a delivery · photos with a certified date · evidence of damage to goods

A photo without a trusted date proves little: the date inside a file can be changed by anyone, and the other side knows it. Certifying them turns "this is how it was" into something that admits no argument.

## When it pays off

| Moment | What is protected |
| --- | --- |
| Receiving goods | The condition they arrived in |
| Handing over work | What was delivered and how |
| Starting a job | The prior condition, before anything is touched |
| Damage or an incident | That it happened when you say, not after |

## How to take them so they count

**En corto**

- One wide shot for context, then the details.
- Include something that anchors the place: a serial number, a registration, a sign.
- Certify them the same day, not when the problem appears.

> [!IMPORTANT]
> Certifying months later fixes nothing: the certified date is today's. If the photos matter, the moment to certify them is the day they are taken.

> [!WARNING]
> Do not retouch or crop photos before certifying. Any edit changes the file, and the other side will ask why it was edited.

> [!NOTE]
> Prior condition is the most forgotten and the most argument-saving: four photos before starting costs two minutes and closes the "that was already broken" claim.

**How many photos can I certify at once?**

A whole set, certified as a set.

**Does a phone photo count?**

Yes. What is certified is the file, not the camera.

**Can it be shared with the client?**

Yes, and they can verify without an account.

## Ejemplos

**An installer receives a claim for damage that predated their work.**

- Retrieves the certified photos from the day they started

→ The claim closes in an afternoon; without them it would have been their word against the client's.

**A site photo carries no provable date.**

- Seals the photo the same day

→ The date stops being argued.

**Photos live on the foreman's phone.**

- Uploads and seals them from that phone

→ The record outlives the handset.

**There is a dispute whether damage predated a delivery.**

- Seals the receipt photos

→ The initial condition is provable.

**A hundred photos are taken and sealing one by one is impractical.**

- Seals the set at once

→ The cost does not grow with the number of photos.

**The photo is sealed weeks after being taken.**

- Seals at the moment of capture

→ The seal says what you want it to say.
