Check a signature

The address notarity.com/signature-check appears in the signature field of every document signed on the notarity platform. This page explains how to check those signatures.

Documents are signed electronically, in compliance with eIDAS. You can check yourself whether a signature is genuine and whether the document has changed since it was signed.

Check online

Upload the PDF to one of these validation services:

• RTR signature check
• European Commission validation service

Check in Adobe Acrobat

1. Open the PDF in Adobe Acrobat and click the Signatures tab on the left.
2. Click “Validate All”.
3. If a signature is shown as invalid, Acrobat also gives the reason, for example “1 Page(s) Added”: a page was added after signing.

To see exactly what changed, right-click the signature and choose “Compare Signed Version to Current Version”.

To check the signature itself, click “View Signed Version”. This opens the document as it was when it was signed. You can save that version separately and upload it to one of the validation services above.
