Anyone who hasn't already typed "sign a Word doc" into the Google search bar, raise your hand! There are a lot of you out there, and that's no surprise, since Word is a mainstay of digital documentation, especially in the corporate world. 

It's not uncommon, for example, to find attachments for signature in e-mails, often in PDF or Word format... It's then up to the person sending the document to make sure it's signed, and for the person receiving it to sign it properly. This procedure is commonplace, but can prove time-consuming and a source of potential errors, especially at a time when every company is dealing with a considerable number of documents, each with its own distinct challenges.

So how do you sign or have signed all your business documents in Word efficiently, simply and securely? Here's how.

Word: an essential tool in the professional world

You won't deny it: Microsoft Word has established itself as theword-processing tool par excellence in the professional world. Its universal adoption by organizations of all sizes underlines not only its accessibility, but also its ability to meet a multitude of documentation needs.


💡 Please note: 

Word can refer to both a tool (the software) and a format (generally .docx in its latest version): 

  • The Word tool It offers a wide range of advanced features for editing, formatting and revising content.
  • Word format Word format: This is a standardized format for sharing and storing digital documents, facilitatinginteroperability between different users and systems. This format makes professional exchanges more fluid.


The types of documents that can be written and signed electronically in Word are varied and include, among others :

  • Employment contracts,
  • Partnership contracts,
  • Sales proposals and quotations,
  • Balance sheets and annual reports,
  • Internal company policies, 
  • Etc.


Each type of document has specific specific implicationslegal, contractual or financial legal, contractual or financialrequiring particular care in the choice of signature method. This decision must be taken with discernment to guarantee the validity and conformity of the signed document.


💡 The 4 levels of electronic signature

The European eIDAS provides for several levels of security for electronic signatures:

  • Simple, for documents with few regulatory constraints or financial implications (internal company documents, low-value orders, etc.). 
  • Advanced, for documents with regulatory constraints and moderate financial implications (employment contracts, sales agreements, etc.).
  • Advanced based on a qualified certificate, specifically dedicated to utilities.
  • Qualified, for documents with regulatory constraints and high financial stakes (life insurance contracts, government contracts, etc.).


On Word, all these levels of electronic signature can be used, but there are a number of sometimes restrictive conditions to be met, which tip the balance in favor of a dedicated signature tool.

The Word electronic signature in practice

Limits to using Word to sign documents electronically 

L'he use of Word for electronic signatures is possible, but has several disadvantages disadvantages, in several respects:

  • Document management Managing separate files requires rigorous classification. What's more, documents have to be sent by e-mail for signature, making follow-up more time-consuming and lengthening the process.
  • Tool accessibility Using Word requires signatories to have a license to open the file. This requirement can be restrictive, as not all potential signatories have access to Word.
  • Legal validity of printed/scanned documents When a Word document is printed, manually signed and then scanned, this signature is not an electronic signature in the eyes of the French civil code. This process does not guarantee the integrity of the document. In other words, there is no guarantee that the content of the document has not been altered or modified after it has been signed. This method, although widely used, also fails to meet the criteria for a simple signature under the eIDAS regulation.
  • A demanding process for qualified signatures The integration of a qualified electronic signature via Word requires the prior acquisition of a qualified electronic certificate, stored on a cryptographic medium. This requirement can be a complex and costly process to set up.


💡 What is a digital certificate on a cryptographic medium?
The digital certificate on cryptographic medium is a secure digital certificate associating identification information with a pair of cryptographic keys (a public key and a private key), stored on a secure hardware device. Schematically, this certificate is a digital identity card, making it possible toauthenticate the identity of the signatory in an electronic signature process. It is used to prove the validity, reliability and level of security of the electronic signature.

💡 Why convert to PDF/A format?

To ensure the legibility (remember that PDF stands for "Portable Document Format") and semantic stability (thanks to PDF's "/A" format) of electronically signed documents over time and in all environments, it is crucial to convert Word files into PDF/A format before signing. This step is essential because, unlike Word documents which may contain software-specific macros or fonts, PDF/A files remain readable and stable over time. This is crucial for legal and official documents whose content must be indisputable.
