Electronic signature for SARL articles of association in 2026

Introduction: dematerialising SARL creation, a consolidated legal reality

Since the PACTE Act of 2019 and Ordinance No. 2021-1192 of 15 September 2021 reforming the law on security interests and confirming the probative value of acts signed with a private electronic signature, the electronic signature of SARL articles of association is legally valid in France. In 2026, the majority of commercial court registries accept fully dematerialised creation files via the INPI single gateway, which opened in January 2023. For entrepreneurs, partners and accountants, understanding when and how to use electronic signature when establishing a company has become an essential skill. This article details the applicable framework, the signature levels required, pitfalls to avoid and best practices for smooth and compliant business creation.

Why electronic signature is becoming essential in SARL creation

A favourable regulatory context since 2021

Ordinance No. 2021-1192 amended Article 1367 of the French Civil Code to consolidate the recognition of electronic signature in legal acts, including articles of incorporation. In parallel, Decree No. 2021-1572 of 2 December 2021 clarified the implementation procedures for acts signed with a private electronic signature filed with the registry. Concrete result: an SARL articles of incorporation signed electronically by all founding partners has the same evidential value as an original paper document, provided the solution used complies with eIDAS regulations and their technical requirements.

In practice, the INPI single gateway has allowed since 2023 the filing of the entire creation file online, attaching the articles in PDF format signed electronically. Registries process these files within the same timeframes as paper files — even faster in some cases, as OCR and automated checks reduce rejections for formal errors.

Concrete benefits for founders and their advisers

Sector studies published by CPME and the National Federation of Accountants estimate that dematerialising the creation process reduces by 40 to 60% the administrative time devoted to document collection and sending. For an accountancy practice managing several dozen creations per year, this represents several hundred hours saved. For an individual entrepreneur creating their first SARL, the elimination of postal or physical back-and-forth with co-partners is a decisive advantage, especially when they are geographically dispersed.

What level of electronic signature for SARL articles of association?

The three eIDAS levels and their applicability

Regulation eIDAS No. 910/2014, directly applicable in French law, distinguishes three levels of electronic signature:

• Simple Electronic Signature (SES): basic identification of the author, limited evidential value.
• Advanced Electronic Signature (AES): linked uniquely to the signer, enabling their identification, created using data under their exclusive control, and detecting any subsequent modification of the document.
• Qualified Electronic Signature (QES): the highest level, equivalent to a handwritten signature in European law, issued by a Qualified Trust Service Provider (QTSP) registered on the national trust list.

For SARL articles of association under private deed — the most common form — Advanced Electronic Signature (AES) is generally sufficient and constitutes the standard recommended by legal practitioners. It offers a level of security appropriate to articles of incorporation whilst remaining accessible and smooth for signers.

Special case: SARLs with property contributions or notarial acts

When contributions in kind include real estate property, the articles must be drawn up by notarial act (Article L.223-9 of the French Commercial Code). In this case, it is the notary who uses their own qualified electronic signature, in accordance with the rules of the notary's chamber. The "SaaS" electronic signature of the partners does not replace the compulsory notarial intervention.

Similarly, if the SARL is subject to specific formalities (for example: regulated sector requiring prior approval), it is advisable to check with a specialist law firm whether particular form requirements apply.

Time stamping and archiving: overlooked obligations

Beyond the signature itself, the legal value of an electronic act also rests on qualified time stamping (ETSI EN 319 422 standard) and the ability to produce a complete audit trail in the event of dispute. A professional electronic signature solution must generate an unfalsifiable audit log mentioning the signer's identity, the time and date of signature, the IP address and the cryptographic hash of the document. These elements are essential to enforce the signature against a third party — including the registry or tax authorities.

Practical process: sign your SARL articles online step by step

Step 1 — Document preparation

SARL articles must necessarily mention, according to Article L.223-7 of the French Commercial Code: the legal form, the corporate purpose, the company name, the registered office, the share capital, the contributions of each partner, the distribution of shares and the company's duration. It is recommended to work from models compliant with current regulations. The Certyneo AI contract generator offers updated article templates, pre-formatted for filing at the INPI single gateway.

Once the document is finalised and converted to PDF/A (long-term archival format recommended by ISO 19005 standard), it is ready to be sent for signature.

Step 2 — Identification of signers and sending

Each founding partner must be invited to sign via the electronic signature platform. For AES compliant with eIDAS, signer identification is generally carried out by:

• An OTP code (one-time password) sent by SMS to the previously verified telephone number;
• Identity document verification (scan of ID card or passport) for larger amounts or more significant matters.

The platform then generates a secure signature link transmitted to each partner. They can sign from any device (computer, tablet, smartphone) without software installation.

Step 3 — Retrieval and filing with the registry

Once all partners have signed, the platform produces an electronically signed PDF document, accompanied by its signature certificate and audit trail. This document can be directly filed on the guichet-entreprises.fr or formalites.entreprises.gouv.fr portal (INPI). The registry checks the validity of the electronic signature via ETSI standards and validates the registration.

For teams handling many company creations, integrating electronic signature into an automated workflow — via API — allows triggering the sending for signature as soon as the articles are validated in the business software. This approach is detailed in our comprehensive guide to electronic signature in business.

Common mistakes to avoid when electronically signing SARL articles

Using a non-compliant eIDAS solution

Not all electronic signature solutions are equal. A simple text input field or a scribble image inserted into a PDF does not constitute an electronic signature in the legal sense. To be enforceable, the signature must be produced by a registered or compliant trust service provider (TSP). In case of dispute, a non-compliant signature will be rejected by the court, which could result in the nullity of the act.

It is therefore essential to choose a certified solution, such as those compared in our electronic signature solutions comparison.

Failing to retain audit evidence

The audit log generated during signing must be retained for the entire life of the company, and at minimum for the five-year prescription period applicable to civil acts (Article 2224 of the French Civil Code). Certyneo automatically archives signed documents and their evidence for 10 years, in compliance with GDPR requirements and CNIL recommendations.

Confusing SARL and EIRL in terms of formalities

Whilst EIRL (Entrepreneur with Limited Liability) was abolished for new creations since the Act of 14 February 2022 — replaced by the sole status of self-employed individual — some practitioners still manage existing EIRLs. The procedures for modification or closure of an EIRL do not follow the same rules as those of an SARL. For these situations, please consult the electronic signature glossary and, if necessary, specialist legal advice.

Legal framework applicable to electronic signature of articles of association

Foundational European legislation

The Regulation (EU) No. 910/2014 of the European Parliament and of the Council of 23 July 2014, the eIDAS regulation, constitutes the regulatory foundation for electronic signature in Europe. It establishes the three levels of signature (simple, advanced, qualified), defines qualified trust service providers (QTSP) and creates national trust lists overseen by supervisory authorities — ANSSI in France. eIDAS Regulation 2.0, progressively deployed since 2024, strengthens interoperability requirements and introduces the European digital identity wallet (EUDI Wallet).

GDPR No. 2016/679 applies to the processing of signers' personal data (name, email address, telephone number, biometric data where applicable). Electronic signature providers must be able to produce a processing activities record, appoint a DPO if necessary, and guarantee individuals' rights (access, rectification, erasure).

National law

Article 1366 of the French Civil Code establishes the principle of equivalence between electronic writing and paper writing: "An electronic writing has the same evidential value as a writing on paper, provided that the person from whom it emanates can be duly identified and that it is established and retained in such conditions as to guarantee its integrity."

Article 1367 of the French Civil Code defines electronic signature as "the use of a reliable identification process ensuring its link with the act to which it relates" and creates a presumption of reliability for qualified signatures.

Ordinance No. 2021-1192 of 15 September 2021 strengthened the consistency between the provisions of the French Civil Code and eIDAS regulation, particularly on the notion of electronic authentic act and act signed with a private electronic signature.

Decree No. 2017-1416 of 28 September 2017 specifies the conditions for reliability of the electronic signature process for acts signed with a private signature, in particular requiring the use of certificates compliant with ETSI EN 319 132 (XAdES) or ETSI EN 319 122 (CAdES) or ETSI EN 319 142 (PAdES) standards.

Practical obligations and risks

A non-compliant electronic signature exposes founders to the risk of nullity of the articles of incorporation, which may result in the registry's refusal to register the company or, subsequently, challenge by a partner or creditor. On a tax basis, the tax authority may also question the date certainty of an act whose signature is not validly established. It is therefore imperative to choose a provider whose eIDAS compliance is documented and audited, and to retain all audit evidence for at least the prescription period applicable.

Use scenarios: electronic signature of SARL articles in practice

Scenario 1 — An accountancy practice handling creations on a large scale

An accountancy practice with about ten staff accompanies on average 80 to 120 company creations per year, with the majority being SARLs. Before dematerialisation, each file required printing, handwritten signature and digitalisation of the articles, followed by postal sending or physical delivery to each partner. The average time between finalisation of the articles and receipt of documents signed by all partners reached 7 to 12 business days.

Since integrating an advanced electronic signature solution connected to their management software, this timeframe has fallen to less than 48 hours in more than 85% of files. Partners sign from their smartphone, wherever they live. The audit log is automatically archived in the client file. The practice estimates a saving of 3 to 4 hours of administrative work per file, equating to a total saving of 240 to 480 hours annually redirected to value-added advice.

Scenario 2 — Founding partners geographically dispersed

Three entrepreneurs wish to establish an SARL to develop consulting activities. One lives in the Paris region, the second in Bordeaux, the third works remotely from Lisbon under the digital nomadism scheme. Without electronic signature, coordinating signature of the articles would have required either a common meeting or successive recorded mail exchanges with unavoidable delays of 10 to 15 days.

Thanks to an advanced electronic signature platform, the three partners simultaneously receive a signature link by email. Each identifies themselves via an OTP SMS, consults and signs the document in under 5 minutes. The total time for collecting the three signatures is under 2 hours. The complete file is filed on the INPI single gateway the same day, and registration occurs within 5 business days.

Scenario 3 — A business creation support structure

A public business creation support structure (business incubator) accompanies between 50 and 80 business project leaders each year in the establishment of their first company. It offers a turnkey service including drafting articles via a customisable generator and collecting electronic signatures from founding partners.

Integration of an electronic signature API into its support platform allows automatically triggering the signature process as soon as the articles are validated by an adviser. Registry rejection rates for formal reasons (missing signatures, illegible documents) fell from 18% to less than 3% after complete dematerialisation of the process. The average creation support duration was reduced from 22 to 14 days, significantly improving satisfaction among accompanied entrepreneurs.

Conclusion

Electronic signature of SARL articles is today a legally sound, technically accessible and economically advantageous practice. The European regulatory framework (eIDAS) and national law (French Civil Code, Ordinance 2021-1192) provides robust legal security provided the solution used complies with Advanced Electronic Signature standards. Time savings — measured at 40-60% of the overall administrative process — and elimination of geographical constraints make dematerialisation a major lever for founders, accountants and legal advisers.

The key takeaway: choose an eIDAS-compliant provider, use the right signature level (AES as a general rule), retain audit evidence and take into account the specificities of SARLs with notarial contributions.
