Electronic signature of employment contract: 2026 guide (legal framework, levels, procedure)

Yes, without ambiguity. The Labour Code imposes no particular form for the employment contract (except fixed-term contracts which must be in writing). Electronic signature is fully valid for permanent contracts, fixed-term contracts, apprenticeship contracts, training contracts, and amendments.

Legal framework 2026: what the Labour Code and eIDAS say

Electronic signature of an employment contract has been explicitly authorised by French and European law for over 20 years. Three texts govern its legal validity:

• Article 1366 of the Civil Code (law of 13 March 2000): electronic writing has the same probative force as paper writing, provided that the author can be identified and the integrity of the document is guaranteed.

• Article 1367 of the Civil Code: electronic signature compliant with the European eIDAS regulation is legally equivalent to handwritten signature. This equivalence is total for qualified signature (QES) and presumed for advanced signature (AES).

• Labour Code: no provision requires paper form for the employment contract. The permanent employment contract (CDI) can even remain verbal — only writing secures it. For fixed-term contracts and temporary work, writing is mandatory (articles L1242-12 and L1251-16) but may take electronic form.

• Regulation (EU) No 910/2014 (eIDAS): defines the three levels of electronic signature recognised throughout the European Union — Simple (SES), Advanced (AES) and Qualified (QES). The eIDAS 2.0 regulation (EU 2024/1183, June 2026) strengthens this framework with qualified remote signature.

No case law in France has challenged the validity of an employment contract signed electronically since the law of 2000. Employment tribunals unanimously accept electronic signature as evidence, provided the conditions of article 1366 are met.

Why is AES level recommended for employment contracts?

The employment contract binds the employer to long-term obligations (salary, working conditions, termination compensation). In case of dispute, the burden of proof lies with the employer. Advanced signature (AES) benefits from a legal presumption of integrity and origin: it is the employee who must prove the signature is forged, not the employer who must prove it is valid. This reversal of the burden of proof is decisive in case of litigation.

In practice, AES on Certyneo relies on strong authentication of the signatory (email + SMS OTP, compliant with ANSSI requirements), a timestamped RFC 3161 audit trail, and storage with probative value for 10 years. These three elements are sufficient to establish the validity of the contract before employment tribunals, civil courts or courts of appeal.

The Court of Cassation and the Directorate-General for Labour have recalled this on several occasions: a contract signed electronically has the same value as a paper contract.

Which signature level to choose

For an employment contract, advanced signature (AES) is strongly recommended:

• strong identification of the employee (email + SMS OTP)

• detailed audit trail

• presumption of reliability before employment tribunals

Simple signature (SES) is legally possible but proof is weaker in case of dispute. See the 3 levels.

Recommended procedure

• Prepare the contract in your template (Word/PDF)

• Attach mandatory annexes: internal rules if more than 50 employees, IT charter, profit-sharing scheme

• Send in AES with SMS OTP to the employee's personal telephone

• Monitor signature in real time

• Archive the signed PDF + audit trail for 5 years after the end of the contract

Mandatory provisions

The electronic employment contract must contain the same provisions as a paper contract:

• identity of the parties

• position, classification

• remuneration, frequency

• duration (for fixed-term contracts) or CDI mention

• probation period

• place of work, working time

• applicable collective agreement

Documents to attach

Depending on the context, remember to attach to the same envelope:

• internal rules (companies ≥ 50 employees)

• IT charter

• mutual insurance/provident notice

• profit-sharing or participation plan

• teleworking agreement if applicable

Common mistakes

• SES for a contract with significant stakes: prioritise AES

• Sending the contract alone without mandatory annexes

• Keeping only the PDF without the audit trail

• Printing the signed contract (loss of probative value)

• Failing to verify receipt of the contract by the employee before starting work

Use case: remote permanent contract

A candidate based in Nantes accepts an offer from a Parisian SME. Course of action:

• Tuesday 10am: oral acceptance by email

• Tuesday 11am: sending contract + internal rules + IT charter in AES

• Tuesday 12:30pm: contract signed (SMS OTP), return in PayFit

• Wednesday 9am: start of remote work

Entire process in less than 24 hours, zero travel, enforceable proof established.

Special case: apprenticeship contract

The apprenticeship/training contract goes through the CERFA system. Electronic signature is now accepted by training bodies on the condition of using an eIDAS-compliant provider.

Does the employee sign from their telephone?

Yes, it is the most commonly used channel.

Can minors on apprenticeship contracts sign?

Yes, with co-signature of the legal representative in the same envelope.

Can termination by mutual agreement be signed electronically?

Yes, since the DGT order. Subsequent online homologation.
