# A sample certificate of signing: The page you'd show a court, a regulator or the other side.

> A sample sig certificate of signing: what was signed, who signed with a still from their video, where and on what, and what happened, to the second.

Source: https://unforged.ai/sig/proof

Every package ends with one of these. It's added to the back of each signed copy and you can download it on its own. The people and places here are made up.

1. **What was signed**: Each document's fingerprint before signing, so a swapped page would show.
2. **Who signed**: A still from their video beside their signature, with how we know it was them.
3. **Where and on what**: Their location and its source, the network address and the device in plain words.
4. **What happened, in order**: Every send, view, signature and reminder, to the second.
