Electronic signature vs handwritten: the comparison

Two signatures, one and the same function

The signature, whether electronic or handwritten, fulfils three identical legal functions: it identifies the signatory, expresses their consent to the content and guarantees the integrity of the document. What changes is the technique that provides proof of each of those three functions.

Contrary to popular belief, the electronic signature is not a digital imitation of paper. It is a cryptographic process that is, in many respects, more robust than a handwritten initial.

Legal standing

Both signatures are recognised as equivalent under French law since Act no. 2000-230 of 13 March 2000 (article 1367 of the Civil Code). The European eIDAS regulation reinforced that equivalence in 2016 by laying down the principle of non-discrimination: an electronic signature cannot be refused as evidence on the sole ground that it is electronic.

For perfect equivalence with a handwritten signature, aim for a qualified signature (QES): it carries the same legal value as a handwritten signature throughout the European Union. Advanced (AES) and simple (SES) signatures remain perfectly valid, but their probative value is assessed case by case by the judge — see the differences between the three levels.

Speed

This is the most striking point for operational teams.

Step | Paper | Electronic

Preparing the document | 10 min | 2 min

Sending to the signatory | 1 to 3 days (post) or minutes (scan) | < 1 minute

Signed copy returned | 2 to 5 days on average | Minutes to a few hours

Filing / archiving | Manual | Automatic

Over a full sales cycle, the electronic signature divides the turnaround by 5 to 10. At high volumes (HR, real estate, training), the impact on cash flow and customer satisfaction is measurable.

Traceability

Paper leaves nothing but a scribble. There is no way to prove when exactly the signature was applied, where it came from, or whether the document has been altered since.

The electronic signature, by contrast, carries a time-stamped audit trail:

• the precise date and time of every viewing and signature
• the signatory's IP address and browser identifier
• proof of identification (OTP code entered, authentication)
• a cryptographic hash of the document that invalidates any later change

That audit trail is embedded in the final PDF and stays consultable for 10 years. In a dispute it is the main evidence you can bring before a court. See electronic signature evidence.

The full cost

The direct cost of paper (sheet plus printing) is deceptively low. The full cost includes:

• printing and consumables
• recorded delivery with acknowledgement of receipt (between €5 and €10 per envelope)
• administrative time (preparation, chasing, filing)
• physical storage for 10 years
• the risk of loss or alteration

The estimates commonly accepted in the profession put the full cost of a paper cycle at around €15 to €35 per document. An electronic signature typically costs less than one euro per envelope on a business plan.

The advantages that tip the balance towards electronic

• a drastic time saving (cycles divided by 5 to 10)
• lower administrative costs
• better traceability thanks to the audit trail
• remote signing, with no travel
• signed documents centralised in a dashboard
• automatic reminders for inactive signatories
• instant archiving and retrieval
• a smaller paper and carbon footprint
• a smooth, modern customer experience

Where paper keeps its place

Some instruments still require paper form or specific procedures:

• notarial deeds executed before a notary (certain wills, gifts)
• civil registry documents (signed before the registrar)
• certain judicial procedures (service by a bailiff)

For every other document in a company's daily life, the electronic signature is far preferable.

A side-by-side use case: a freelance contract

Take a freelance services contract worth €5,000.

On paper: printing, recorded delivery (€7), a 2-4 day wait, a phone chase, the return 3-5 days later, scanning for the archive, physical filing. Total: a 5-9 day cycle, a risk of loss, and weak evidence in a dispute.

With an electronic signature: envelope prepared in 3 minutes, sent instantly, signed by OTP in under an hour, signed PDF archived automatically with its audit trail. Strong evidence, marginal cost.

FAQ

Is an electronic signature easier to challenge?

No — in most cases it is the opposite. The time-stamped audit trail, the IP address and strong authentication make an electronic signature harder to challenge in good faith than a simple handwritten initial.

Can an electronically signed document be printed?

Yes, but the printout loses the probative value. It is the digital PDF that carries the cryptographic signature and the hash. Once printed, you only have a visual copy.

Can a handwritten signature be scanned and used as an electronic signature?

A scanned image pasted into a PDF is not an electronic signature within the meaning of eIDAS — it offers neither identification nor integrity. For a valid signature, go through a dedicated platform.

Do bilingual contracts need two signatures?

No. A single bilingual PDF can be signed once. The electronic signature has nothing to do with the language of the document.

How do I archive an electronically signed document?

The signed PDF is archived like any other digital file, but it is advisable to keep the audit trail and the timestamp. See how to archive a signed document.

Conclusion

The electronic signature is not a "substitute" for paper: it is an improvement. Faster, more traceable, cheaper, legally equivalent in the vast majority of cases. The real question is no longer whether to go digital, but when.
