When I download a signed contract as PDF, it is unlocked for changes - how can I assure only the original copy is valid?
All PDFs of signed contracts can be edited, once downloaded from our platform.
Nevertheless, all fully signed contracts are cryptographically sealed, and once edited the signature is no longer valid.
If you have more questions or need us to check a specific document, kindly send us the original PDF downloaded from Contractbook and the edited version of the same document.
You can make this submission at email@example.com
