Internship Convention Electronic Signature 2026

Introduction

Every year in France, more than 2 million internship conventions are established between educational establishments, students and host companies. This three-part documentary framework, regulated by Act No. 2014-788 of 10 July 2014 known as the Cherpion-Gille Act, traditionally involves cumbersome paper circulation, delays of several days and a real risk of signature loss or error. In 2026, internship convention electronic signature has become the natural solution to streamline this process. But is it really legal? What conditions must be met? How do we involve all three signatory parties? This article answers all these questions with precision and guides you step by step towards secure and compliant dematerialisation.

The internship convention: recap of the mandatory framework

What French law says

The internship convention is a mandatory document whenever a student undertakes an internship in a company, regardless of its duration. It is governed principally by the Code of Education (articles L.124-1 to L.124-20) and clarified by Decree No. 2014-1420 of 27 November 2014. Unlike an employment contract, it does not create a relationship of subordination or salary, but it legally commits all three parties: the educational establishment (pedagogical guarantor), the host company (responsible for conditions of practice) and the trainee student (beneficiary of professional training).

The convention must obligatorily include:

• The title of the training programme and the activities assigned
• The start and end dates of the internship
• The weekly duration of attendance
• The amount of compensation (mandatory beyond 2 months) and payment methods
• The identity of the educational supervisor and the internship supervisor
• The methods of assessment and validation

Three parties, three signatures: the logistical challenge

The main barrier to dematerialisation lies in the need to collect three distinct signatures: that of the legal representative (or authorised signatory) of the company, that of the representative of the educational establishment, and that of the student. On paper, this involves printing three copies, physical or postal circulation, and delays that can reach 10 to 15 working days — a timeframe often incompatible with the constraints of rapid internship commencement.

Electronic signature for HR solves precisely this problem by enabling sequential or parallel digital circulation of documents, with automatic notification of each signatory.

Is electronic signature of an internship convention legal?

Principle of equivalence between handwritten and electronic signature

Yes, electronic signature of an internship convention is perfectly legal under French law. Article 1366 of the Civil Code states that "electronic writing has the same probative force as writing on paper", provided that the identity of the person from whom it originates can be duly identified and that the document is established and preserved in conditions that guarantee its integrity.

The European eIDAS Regulation No. 910/2014, applicable throughout the European Union, distinguishes three levels of electronic signature:

1. Simple Electronic Signature (SES): minimal level, suitable for documents with low legal risk
2. Advanced Electronic Signature (AES): uniquely linked to the signatory, capable of identifying the signatory, created using data under the exclusive control of the signatory
3. Qualified Electronic Signature (QES): highest level, absolute legal equivalent of handwritten signature throughout the EU

For a contractual document such as an internship convention — a document with moderate legal risk — Advanced Electronic Signature (AES) constitutes the recommended level. It provides an optimal balance between legal certainty, ease of use and cost.

What level of signature for an internship convention?

Although the law does not explicitly prescribe a minimum level of electronic signature for internship conventions (no specific text requires it), several parameters guide the choice:

• The desired probative value: an AES offers complete traceability (qualified timestamp, IP address, verified email identifier, audit trail) that will withstand any future dispute.
• The profile of signatories: students rarely have a qualified certificate. Advanced signature via OTP (One-Time Password) sent to mobile telephone is therefore the most suitable method.
• Requirements specific to certain establishments: a few major schools or universities have formalised their signature policy in their internal regulations. You should consult this.

How to implement electronic signature of an internship convention?

Step 1: Prepare and structure the document

Before anything else, the internship convention must be drafted in a non-modifiable digital format: PDF/A is the recommended standard for long-term legal archiving. All mandatory provisions must appear in the document before sending for signature. Any modification post-signature would invalidate the document.

Some platforms such as Certyneo integrate an AI-powered contract generator that can automatically pre-fill variable fields (dates, names of parties, job title, supervisors) from a template validated by your legal teams.

Step 2: Configure the tri-partite workflow

The particularity of the internship convention lies in its three-signatory workflow. The recommended configuration is as follows:

• Sequential order: the company signs first (validation of hosting), then the educational establishment (pedagogical validation), then the student (formal acceptance). This order corresponds to the logic of decreasing responsibility.
• Automatic reminder deadlines: set reminders at D+2 and D+5 to prevent circuit blockages.
• Completion notification: upon the final signatory's signature, each party automatically receives a signed copy in PDF format with integrated signature certificate.

A comparison of electronic signature solutions will help you identify the platform best suited to your volumes and technical constraints.

Step 3: Authenticate signatories

Authentication is the heart of the probative value of advanced signature. For each signatory, the platform must collect and record:

• Email address (verified by clicking a confirmation link)
• Mobile telephone number (OTP code sent by SMS at the time of signature)
• IP address and timestamp of the signature act
• Cryptographic fingerprint (hash) of the signed document

These elements constitute the electronic audit trail (LTV — Long Term Validation) that will allow, in case of dispute, to prove before a court that the correct signatory indeed signed the correct document on the correct date.

Step 4: Archive signed conventions

An internship convention signed must be stored securely. The prescription period applicable to obligations arising from a contract between non-merchants is 5 years (article 2224 of the Civil Code). For internship conventions, the recommended retention period is 5 years from the end of the internship.

Prioritise a certified digital safe or electronic archiving system (SAE) compliant with NF Z 42-013 standard. Consult our electronic signature glossary to understand the differences between simple archiving, digital safe and certified SAE.

Particular cases and frequently asked questions

Can minors sign electronically?

Secondary school pupils undertaking discovery internships or periods of professional training (PFMP) are often minors. Under French civil law, a minor does not have full legal capacity to sign alone an act committing their responsibility. The convention must therefore be co-signed by the legal representative (father, mother or legal guardian). Technically, this means that a 4th signatory must be provided in the workflow when the student is a minor.

Internship abroad: what precautions?

For internship conventions involving a company outside the EU, the legal value of advanced electronic signature depends on applicable local law. Several French establishments choose in this case for:

• A qualified signature (QES) to maximise international recognition
• An electronic apostille if the receiving country is party to the 1961 Hague Convention

In any case, the French educational establishment remains subject to French law for the part that concerns it.

What about educational annexes?

The internship convention is often accompanied by annexes (code of ethics, company internal regulations, detailed job description). These documents can be annexed to the main PDF before sending for signature or be subject to separate signature workflows. The golden rule: any document whose signature you want to be able to oppose must be included within the scope of electronic signature, not transmitted separately afterwards.

Our dedicated HR solution enables the management of complex document packages with management of annexes linked to the main convention.

Concrete benefits for the three stakeholders

For the host company

HR services and operational managers are often first hindered by the delays in signing paper conventions. A trainee whose commencement is conditional on receipt of the signed convention may see their integration postponed by several days, which harms productivity and company image.

With electronic signature:

• Reduced signature timeframe: from 8-15 working days to less than 24 hours in the majority of cases
• Zero printing, postage and scanning costs: a SME handling 50 internships/year can save between €500 and €1,500 annually
• Complete traceability: no more risk of lost convention, unsigned version or missing signature

For the educational establishment

Universities, major schools and vocational secondary schools handle massive volumes of conventions. A medium-sized engineering school can manage 1,500 to 3,000 conventions per year. Dematerialisation enables:

• Centralising monitoring in a single dashboard
• Automatically triggering compensation reimbursements or pedagogical validations
• Creating a documented archive database in compliance without additional effort

For the student

The student benefits from a smooth, 100% mobile experience: receive the convention by email, sign it from their smartphone in less than 2 minutes, and immediately have a certified copy. This simplicity is particularly appreciated in a context where administrative procedures perceived as complex harm engagement.

Using a recognised solution, compliant with eIDAS 2.0 regulation, guarantees the student that their signature has the same legal value as their handwritten signature.

Legal framework applicable to electronically signed internship convention

Foundational texts

The legal validity of an electronically signed internship convention rests on a solid legislative foundation:

• Civil Code, articles 1366 and 1367: electronic writing has the same probative force as paper writing; electronic signature consists in the use of a reliable identification procedure guaranteeing its link with the act to which it attaches.
• Act No. 2000-230 of 13 March 2000: first transposition into French law of the European Directive on electronic signatures, the foundation of the legal recognition of electronic documents.
• eIDAS Regulation No. 910/2014 of the European Parliament and Council: establishes the unified European legal framework for electronic signatures, electronic seals, qualified timestamps and trust services. Directly applicable in all Member States without national transposition.
• eIDAS 2 Regulation (EU Regulation 2024/1183): gradual entry into application from 2025 onwards, it strengthens identity requirements and introduces the European digital identity wallet (EUDIW). Providers of qualified trust services must comply with it.
• Code of Education, articles L.124-1 to L.124-20: governs the mandatory content of internship conventions and the responsibility of the parties.

Obligations of trust service providers

Any provider offering qualified electronic signature services must appear on the National Trust List published by ANSSI for France. Certyneo operates in accordance with ANSSI requirements and technical standards ETSI EN 319 132 (XAdES), ETSI EN 319 122 (CAdES) and ETSI EN 319 142 (PAdES) for the creation and validation of advanced and qualified electronic signatures.

GDPR and processing of personal data

The electronic signature process involves the processing of personal data (name, surname, email address, telephone number, IP address) subject to Regulation (EU) 2016/679 (GDPR). The main obligations are:

• Inform signatories of the processing of their data (article 13 GDPR)
• Limit the duration of retention to the strict needs of the purpose (legal proof: 5 years recommended)
• Guarantee data security through appropriate technical and organisational measures
• Conclude a DPA (Data Processing Agreement) with the signature provider if it processes data on behalf of the data controller

Risks in case of non-compliance

The use of a non-eIDAS compliant signature solution exposes the company to concrete risks: unenforceability of the convention in case of dispute with the trainee (claim for requalification as employment contract), engagement of the establishment's responsibility for lack of formalism, and potential GDPR violation if the signatories' data is processed without adequate guarantees (fine up to 4% of worldwide turnover or €20 million).

Use scenarios: electronic signature of internship convention in practice

Scenario 1: A business school managing 2,000 conventions annually

A major business school welcoming approximately 2,500 students in initial and continuing training must process nearly 2,000 internship conventions each year — mandatory final-year internships, gap year internships, short and long missions. Before dematerialisation, the internship service mobilised the equivalent of two full-time staff for tracking paper circulation, with an average delay of 12 days between sending the convention and receiving all signatures.

Following deployment of an advanced electronic signature solution with automated tri-partite workflow:

• Average signature timeframe: reduced to 1.8 working days
• Rate of complete conventions at D+3: 94% compared to 41% in paper version
• Estimated savings: elimination of 60,000 printed pages annually, suppression of 80% of manual reminders
• Student satisfaction: measured improvement of 28 points on the "administrative ease" indicator in internal surveys

The internship service was able to redeploy liberated resources to higher value-added missions (pedagogical support, company relations).

Scenario 2: An industrial SME welcoming 30 to 50 interns annually

An industrial company of approximately 180 employees, specialised in the manufacture of precision mechanical components, regularly welcomes interns from higher national diplomas, professional licences and engineering schools. Conventions involve establishments spread across several French regions, making postal exchanges particularly restrictive.

Before dematerialisation, the HR manager spent an average of 45 minutes per internship file (printing, sending, reminders, numérising returns, filing). With a volume of 40 internships/year, this represented approximately 30 hours annually mobilised on tasks without added value.

After integration of electronic signature:

• Time per HR file: reduced to 8 minutes (sending, workflow configuration, automatic archiving)
• Estimated annual gain: approximately 25 hours/year, equivalent to 3 days of work redirected
• Welcome timeframe: interns can be welcomed from the day after their candidacy is accepted, versus 8 days previously
• Archiving compliance: 100% of conventions accessible and archived with complete audit trail, versus 70% in paper version (losses, incomplete filing)

Scenario 3: A network of health establishments and paramedical training

A hospital group of approximately 900 beds welcomes over 400 interns annually in nursing care, physiotherapy, healthcare assistance and other paramedical fields. Conventions involve training institutes (IFSI, IFAS) and students, some of whom are still minors (secondary school internship students).

Specific constraints are multiple: presence of a 4th signatory (legal representative) for minors, requirements of the Regional Health Agency in terms of documentary traceability, and management of French-language conventions sometimes doubled with sector-specific regulatory annexes.

Following deployment of a configurable electronic signature solution with multi-signatory workflow management:

• Average completion timeframe: 2.5 days (versus 14 days in paper version with multiple establishments)
• Regulatory compliance: 100% of conventions archived with qualified timestamp and audit trail compliant with ARS control requirements
• Reduction in completeness error rate: from 22% to less than 3% thanks to automatic completeness checks before sending for signature

Conclusion

Electronic signature of an internship convention is no longer a futuristic option: it is a legal reality, technologically mature and economically justified in 2026. By combining the legal value guaranteed by eIDAS regulation, the simplicity of an automated tri-partite workflow and the traceability required by GDPR, you offer all parties — company, educational establishment and student — a smooth, secure and compliant experience.
