Damage verification: how to document damage so your evidence holds up
Damage appears and the argument begins: who caused it, when, who pays. Damage verification has two halves. The first is confirming the damage. The second is being able to prove it weeks or months later, when someone calls it into question. Almost everyone does the first. Almost no one prepares for the second.
This guide is about the second.
The three moments where everything is decided
Before the damage exists. The day you move into a rental. The day a renovation starts. Documenting the previous state is what later lets you say “this wasn’t here” — or “this already was.”
Right after the damage. An insurance claim, an incident, a delivery that arrives battered. The first few hours are worth more than the next ten days: damage evolves, things get moved, memory adjusts.
Never “when I get a moment.” Every day that passes between the damage and the documentation is a day the other side can use. The perfect photo taken late is worth less than the mediocre photo taken on time.
How to photograph so it makes sense
Three shots per area of damage: wide, medium, close-up. The wide shot establishes the room. The medium one places the damage within it. The close-up shows it. A close-up of a crack, with no context, doesn’t even prove which house it’s in.
Include references. Something for scale (a coin, a tape measure) and something that places it (a window, a door, a recognizable piece of furniture).
Add one continuous video. An uncut sweep of the whole room complements the photos: it’s harder to challenge as cherry-picking.
Don’t delete the “bad” photos. The full series, with repeats and crooked shots, gives more context than three chosen photos — and leaves no room for the question of what you left out.
The paperwork that goes with it
Photos alone tell half the story. Add a written inventory or report with the date and a list of the damage, repair estimates, and your communications with the other party. And one rule that applies to everything: always keep the original files, even if you send copies.
The weak spot: the date
This is the easiest flank to attack in any documentation.
A photo’s date lives in its metadata, and metadata can be edited in seconds with any free tool. WhatsApp, on top of that, strips it when compressing the image. And the “file date” your computer shows may change when you copy or transfer it. The result: “this photo is from the 3rd” is a claim, not proof.
The classic trick of including today’s newspaper doesn’t solve what matters either: it proves the photo isn’t earlier than that date, when what you need to prove is that it isn’t later — that it already existed by then.
The way to fix the date is to seal the file: its digital fingerprint is computed (a kind of unique ID for that exact file) and recorded, with a date, in an independent, verifiable system. The photo is never modified; and depending on the sealing mode, the fingerprint can be computed on your own device, without the file ever leaving it. Later, anyone can check that the file you present is identical, bit for bit, to the one that existed that day. If someone alters it, even by a single pixel, the check fails.
That turns “I had photos” into “I have photos with a provable date.” And that’s exactly the difference between your word against theirs and a conversation with a foundation.
What the proof doesn’t decide
Let’s be clear: sealing proves that this exact file existed, as is, on the date it was sealed. It doesn’t prove when the photo was taken, nor rule out that it was edited before sealing — which is exactly why you seal the same day: the shorter the window between photo and seal, the less room that objection has. It also doesn’t decide who caused the damage or who pays, and it doesn’t replace the insurance adjuster or a technical report. Unsealed documentation can have value too; sealing strengthens it by fixing date and integrity. It’s the foundation on which these conversations stop being he-said-she-said.
Mistakes that weaken your documentation
- Sending photos only through WhatsApp and not keeping the originals.
- Photographing only the damage, with no context shots.
- Documenting days later, “when there was time.”
- Editing or cropping the originals (edit copies; store the originals separately).
- Trusting that “the gallery already keeps the date.”
The two-minute checklist
- Wide, medium and close-up of each area of damage.
- One continuous video of the room.
- A written inventory with the date.
- Originals stored, unedited.
- Everything sealed the same day.
Sealing takes less time than taking the photos and costs cents. What’s usually at stake — a deposit, a repair, an insurance claim — doesn’t.
