Regulatory framework

Qualified signatures are strictly regulated by EU and French law.

This page lists all applicable texts with their exact references and links to official sources. All our commercial claims are verifiable.

1. The eIDAS European Regulation

European Regulation (EU) No 910/2014 of 23 July 2014, known as the eIDAS Regulation, harmonizes electronic signatures across all EU member states. It defines three signature levels:

  • Simple electronic signature (SES) — basic consent (a checkbox).
  • Advanced electronic signature (AES) — requires signer identification (typically by SMS).
  • Qualified electronic signature (QES) — additionally requires a certificate issued by a Qualified Trust Service Provider (QTSP) on the EU Trusted List.

Only the qualified signature benefits from a presumption of reliability and is legally equivalent to a handwritten signature across the entire Union (Article 25.2 of the Regulation).

Article 25.2 of the eIDAS Regulation:
"A qualified electronic signature shall have the equivalent legal effect of a handwritten signature."

Article R123-5 of the French Commercial Code

FR · Decree 2017-1416

"When the act is executed electronically, the signature must be applied through a process compliant with the requirements of Regulation (EU) No 910/2014."

This article requires a qualified electronic signature for filings on the INPI single-window in sensitive cases: company creation, dissolution, modification, trademark filing, patent filing. A simple or advanced signature is legally insufficient.

Article 1367 of the French Civil Code

FR · Law 2016-1547

"The signature necessary to perfect a legal act identifies its author. It manifests his consent to the obligations resulting from this act. […] When electronic, it consists of the use of a reliable identification process guaranteeing its link with the act to which it attaches."

This founding text of French law enshrines the legal value of electronic signatures. Combined with the eIDAS Regulation and Decree No 2017-1416, it positions the qualified signature as the procedural and legal equivalent of the handwritten signature in French courts.

EU Trusted List (EU TL)

EU · Article 22 eIDAS

"Each Member State shall establish, maintain and publish a trusted list, including information related to qualified trust service providers as well as information related to the qualified trust services provided by them."

Our partner Qualified Trust Service Provider is listed on the EU Trusted List. You can verify their status directly on the official Commission site: eidas.ec.europa.eu/efda/tl-browser

Decree No 2017-1416

FR · eIDAS implementation

"The reliability of an electronic signature process shall be presumed, until proof to the contrary, when this process implements a qualified electronic signature."

This decree transposes the technical requirements of the eIDAS Regulation into French law. It establishes the presumption of reliability: in case of dispute before a court, it is up to the contesting party to prove that the qualified signature is not valid — not the other way around.

GDPR — Regulation (EU) 2016/679

EU · Data protection

Certif Europe processes only the personal data strictly necessary for certificate issuance: identity, email, document to sign. All data is hosted in the European Union. See our privacy policy for details.

ETSI EN 319 411

EU · QTSP technical standard

European technical standard defining requirements for Qualified Trust Service Providers issuing electronic signature certificates. Our partner QTSP is annually audited against this standard by an accredited compliance body, in accordance with Article 17 of the eIDAS Regulation.

2. Scope — INPI Single-Window

Since 1 January 2023, the INPI single-window has replaced all French Centres de Formalités des Entreprises (CFE). For sensitive acts, the qualified signature is mandatory:

  • Company creation (registration in commercial register)
  • Company modification (articles, directors, capital, registered office)
  • Dissolution (voluntary, liquidation, deregistration)
  • Trademark filing (national, European, international)
  • Patent filing (national, PCT, validation)
  • Industrial designs and models filing

4. Limitations of our service

For full transparency, here is what we are not:

  • We are not a Qualified Trust Service Provider (QTSP) within the meaning of Article 24 of the eIDAS Regulation. We work with a partner QTSP listed on the EU Trusted List.
  • We are not ANSSI Visa de Sécurité-qualified — this qualification is granted to entities operating their own cryptographic infrastructure, which is not our case.
  • We are not a law firm. For legal questions concerning the content of your act (articles, patent, etc.), consult a lawyer or accountant.

We are an online service simplifying access to a qualified signature certificate issued by a partner QTSP compliant with the eIDAS Regulation.
