What is Document Sealing?
Document sealing means the process whereby a document is downloaded as a PDF, and the document is sealed.
In simple words, the sealed document cannot be tampered with or changed. It is the Electronic Seal, together with a Time Stamp that assures that the document has not been tampered with.
Why using Document Sealing is beneficial?
Let us say two parties sign a contract and each of them downloads that document as a PDF. Then, one of the parties changes the content of the contract.
How can it be proven that the original contract was tampered with and that one party changed it?
When a document is sealed with the Electronic Seal and Time Stamping, and these mechanisms remain intact, all Parties added to the document know that nothing has been changed.

How is a Document Sealed?
After Contractbook users have drafted and signed a contract, they get the option of downloading the document as a PDF.
The moment the last signee signs a contract, Contractbook generates the sealed PDF. Everyone who downloads a fully signed contract as a PDF will download that exact same file. The Timestamp will therefore be set to the last moment of the signature.
Contractbook can claim that the content of the document, including the signatures, is true. Then the seal together with the Timestamp proves that the content of the document has not been changed ever since because of the secure Time stamp which shows the passage of time.
Does the Document Sealing affect the Signature in any way?
No. The signature used to sign the document is not in any way affected by the sealing.
When a document is sealed, we merely ensure that the document has not been changed in any way. This means if the document is signed using SMS verification, the sealing of the document will not change its validity in any way.
The technical part of Sealing Documents
When Contractbook seals a document, two services are needed:
- Qualified Certificate for Electronic Seal
- A Time-Stamping Service
Qualified Certificate for Electronic Seal
- According to eIDAS recital (59) “Electronic seals should serve as evidence that an electronic document was issued by a legal person, ensuring certainty of the document’s origin and integrity.”
- A Qualified Certificate for Electronic Seal is issued by a trust service provider (TSP).
- The TSP Contractbook uses for its Qualified Certificate for Electronic Seal is called Buypass.
A Time-Stamping Service
- Contractbook uses a Qualified Time Stamp that is issued by Certum and is valid in all EU states.
