Electronic Signature for Private Company (SARL) Articles in 2026

Introduction: digitalising SARL creation, a consolidated legal reality

Since the PACTE law of 2019 and Order No. 2021-1192 of 15 September 2021 reforming the law of securities and confirming the probative value of acts under private electronic signature, the electronic signature of SARL articles is legally valid in France. In 2026, the majority of commercial court registries accept applications for creation entirely digitalised via the INPI single window, open since January 2023. For entrepreneurs, associates and accountants, understanding when and how to use electronic signature when forming a company has become an essential skill. This article details the applicable framework, required signature levels, pitfalls to avoid and best practices for seamless and compliant business creation.

Why electronic signature is becoming essential in SARL creation

A favourable regulatory context since 2021

Order No. 2021-1192 amended article 1367 of the Civil Code to consolidate recognition of electronic signature in legal acts, including corporate constitutional acts. In parallel, Decree No. 2021-1572 of 2 December 2021 clarified the conditions of application for acts under private electronic signature filed with the registry. Concrete result: a SARL constituent act signed electronically by all founding associates has the same probative force as a paper original, provided that the solution used complies with the eIDAS regulation and its technical requirements.

In practice, the INPI single window has enabled, since 2023, the filing of the entire creation dossier online, by attaching the articles in electronically signed PDF format. Registries process these dossiers within the same timeframes as paper dossiers — or even faster, since OCR and automated checks reduce rejections for formal errors.

Concrete benefits for founders and their advisers

Sectoral studies published by the CPME and the National Federation of Chartered Accountants estimate that digitalising the creation process reduces by 40 to 60 % the administrative time spent on document collection and sending. For an accountancy firm 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-associates is a decisive advantage, especially when they are geographically dispersed.

What level of electronic signature for SARL articles?

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 probative value.
• Advanced Electronic Signature (AES): uniquely linked to the signatory, allowing 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 under European law, issued by a Qualified Trust Service Provider (QTSP) registered on the national trusted list.

For SARL articles under private deed — the most common form — Advanced Electronic Signature (AES) is generally sufficient and constitutes the standard recommended by legal practitioners. It provides a level of security suited to constituent acts whilst remaining accessible and seamless for signatories.

Special case: SARLs with property contributions or notarial acts

When contributions in kind include immovable property, the articles must be executed by notarial deed (article L.223-9 of the Commercial Code). In this case, it is the notary who resorts to their own qualified electronic signature, in accordance with the rules of the notarial profession. The "SaaS" electronic signature of associates does not replace the mandatory notarial intervention.

Similarly, if the SARL is subject to specific formalities (e.g. regulated sector requiring prior approval), it is advisable to check with a specialised legal firm whether special form requirements apply.

Timestamping and archiving: overlooked obligations

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

Practical process: signing your SARL articles online step by step

Step 1 — Document preparation

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

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

Step 2 — Identification of signatories and sending

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

• A one-time password (OTP) sent by SMS to the previously verified telephone number;
• Document identity verification (scan of ID card or passport) for higher-value or more important stakes.

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

Step 3 — Recovery and filing with the registry

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

For teams processing numerous company creations, integrating electronic signature into an automated workflow — via API — allows triggering signature sending 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 errors to avoid when electronically signing articles

Using a non-compliant eIDAS solution

Not all electronic signature solutions are equal. A simple name entry field or a paraph 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 trust service provider (PSC) or compliant with European standards. If contested, 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 comparison of electronic signature solutions.

Not preserving audit evidence

The audit trail generated when signing must be retained for the entire lifetime of the company, and at minimum for the five-year prescription period applicable to civil acts (article 2224 of the 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

Although the EIRL (Sole Trader with Limited Liability) was abolished for new creations since the Law of 14 February 2022 — replaced by the unified status of sole trader — some practitioners still manage existing EIRLs. The formalities for modification or closure of an EIRL do not follow the same rules as those of an SARL. For these situations, it is advisable to consult the electronic signature glossary and, if necessary, a specialised legal adviser.

Legal framework applicable to electronic signature of corporate articles

Fundamental European texts

The Regulation (EU) No. 910/2014 of the European Parliament and of the Council of 23 July 2014, known as the eIDAS Regulation, constitutes the regulatory foundation of electronic signature in Europe. It establishes the three levels of signature (simple, advanced, qualified), defines qualified trust service providers (QTSP) and creates national trusted lists supervised by competent 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 personal data of signatories (name, e-mail address, telephone number, biometric data where applicable). Electronic signature providers must be able to produce a record of processing activities, appoint a DPO if necessary, and guarantee individuals' rights (access, rectification, erasure).

National law

Article 1366 of the Civil Code establishes the principle of equivalence between electronic writing and paper writing: "Electronic writing has the same probative force as writing on paper medium, provided that the person from whom it emanates can be duly identified and that it is established and preserved in conditions such as to guarantee its integrity."

Article 1367 of the Civil Code defines electronic signature as "the use of a reliable identification procedure guaranteeing its link with the act to which it is attached" and creates a presumption of reliability for qualified signatures.

Order No. 2021-1192 of 15 September 2021 strengthened the consistency between the provisions of the Civil Code and the eIDAS Regulation, particularly regarding the concept of electronic authentic act and act under private electronic signature.

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

Obligations and practical risks

Non-compliant electronic signature exposes founders to the risk of nullity of the constituent act, which may result in refusal of registration by the registry or, subsequently, challenge by an associate or creditor. In tax matters, the tax authorities may also question the date of certainty of an act whose signature is not validly established. It is therefore essential to choose a provider whose eIDAS compliance is documented and audited, and to retain all audit evidence for at least the applicable prescription period.

Usage scenarios: electronic signature of SARL articles in practice

Scenario 1 — An accountancy firm managing creations in series

An accountancy firm with around ten employees assists on average 80 to 120 company creations per year, the majority of which are SARLs. Before digitalisation, each dossier required printing, handwritten signature and digitalisation of the articles, then postal sending or physical delivery to each associate. The average time between finalising the articles and receiving signed documents from all associates reached 7 to 12 working days.

Since the integration of an advanced electronic signature solution connected to their management software, this timeframe has fallen to less than 48 hours in over 85 % of dossiers. Associates sign from their smartphone, regardless of where they live. The audit trail is automatically archived in the client file. The firm estimates a saving of 3 to 4 hours of administrative work per dossier, a total saving of 240 to 480 hours annually reallocated to value-added advice.

Scenario 2 — Founding associates geographically dispersed

Three entrepreneurs wish to form an SARL to develop a consulting business. One lives in the Paris region, the second in Bordeaux, the third works from Lisbon as part of digital nomadism. Without electronic signature, coordinating signature of the articles would have required either a joint meeting or successive registered mailings with unavoidable delays of 10 to 15 days.

Thanks to an advanced electronic signature platform, the three associates simultaneously receive a signature link by e-mail. Each identifies themselves via an SMS OTP, views and signs the document in less than 5 minutes. The total timeframe for collecting three signatures is less than 2 hours. The complete dossier is filed on the INPI single window the same day, and registration takes place within 5 working days.

Scenario 3 — A business creation support structure

A public structure supporting business creation (business incubator or accelerator) assists each year between 50 and 80 project leaders in forming their first company. It offers an all-in-one service including drafting of articles via a customisable generator and collection of electronic signatures from founding associates.

Integration of an electronic signature API into its support platform allows automatically triggering the signature circuit upon validation of the articles by an adviser. The rejection rates at the registry for formal reasons (missing signatures, illegible documents) fell from 18 % to less than 3 % following complete digitalisation of the process. The average duration of creation support was reduced from 22 to 14 days, significantly improving the satisfaction of assisted 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 framework (Civil Code, Order 2021-1192) provides robust legal certainty as long as the solution used respects Advanced Electronic Signature standards. Time savings — measured at 40-60 % on the overall administrative process — and the elimination of geographic constraints make digitalisation a major lever for founders, accountants and legal advisers.

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