France — Code civil articles 1366–1369 + Décret 2017-1416

Statutory Framework

France implements Regulation (EU) No 910/2014 (eIDAS) through a layered architecture in which the substantive private-law equivalence rules sit in the Code civil and the implementing technical conditions sit in a Conseil d’État décret. The principal national instrument is Décret n° 2017-1416 du 28 septembre 2017 relatif à la signature électronique (JORF n° 0229 du 30 septembre 2017), which fixes the conditions under which an electronic signature benefits from the reliability presumption set by Article 1367 alinéa 2 of the Code civil and aligns French law with the QES architecture of eIDAS. The substantive Code civil provisions — articles 1366 to 1369 — were originally introduced as articles 1316 et seq. by Loi n° 2000-230 du 13 mars 2000 (transposing Directive 1999/93/EC), then renumbered and partially rewritten by Ordonnance n° 2016-131 du 10 février 2016 reforming the law of obligations and proof, in force on 1 October 2016. The Agence nationale de la sécurité des systèmes d’information (ANSSI) is the national supervisory body for trust service providers under eIDAS, designated through Décret n° 2009-834 (creating ANSSI) and the operational provisions of Décret 2017-1416 and earlier Décret n° 2010-112; it maintains the French part of the EU Trusted List and publishes a public catalogue of qualified products and services at cyber.gouv.fr/produits-services-qualifies.

Code Civil — Probative Force of Electronic Documents

Article 1366 — Equivalence with Paper

Article 1366 Code civil establishes the foundational equivalence rule. Its operative sentence reads, verbatim: “L’écrit électronique a la même force probante que l’écrit sur support papier, sous réserve que puisse être dûment identifiée la personne dont il émane et qu’il soit établi et conservé dans des conditions de nature à en garantir l’intégrité.” In English: written form on an electronic medium has the same probative force as writing on a paper medium, subject to two cumulative conditions — the person from whom the writing emanates must be duly identifiable, and the document must be established and preserved under conditions guaranteeing its integrity. The rule is technology-neutral: it does not prescribe a specific cryptographic technique or signature tier. Both the identification element (who) and the integrity element (what) must be satisfied for the electronic medium to be admitted with the same evidentiary weight as a paper original.

Article 1367 — Definition and Reliability Presumption

Article 1367 alinéa 1 fixes the general definition: a signature, necessary to perfect a juridical act, identifies its author and manifests their consent to the obligations flowing from the act. Alinéa 2 — the operative provision for electronic signatures — reads, verbatim: “Lorsqu’elle est électronique, elle consiste en l’usage d’un procédé fiable d’identification garantissant son lien avec l’acte auquel elle s’attache. La fiabilité de ce procédé est présumée, jusqu’à preuve contraire, lorsque la signature électronique est créée, l’identité du signataire assurée et l’intégrité de l’acte garantie, dans des conditions fixées par décret en Conseil d’État.” When electronic, the signature consists of the use of a reliable identification process guaranteeing its link with the act to which it attaches; the reliability of that process is presumed until proof to the contrary when the signature is created, signatory identity is assured, and act integrity is guaranteed under conditions fixed by a Conseil d’État décret — i.e., the conditions of Décret 2017-1416. The presumption is rebuttable but shifts the evidentiary burden to the contesting party.

Articles 1368 and 1369 — Conflicts and Authentic Acts

Article 1368 provides the conflict-of-evidence rule: where there is no statute or contract assigning priority, the judge resolves a conflict between titles of equal probative value by every means, determining by all available evidence which title best reflects the true state of facts — relevant when paper and electronic versions of the same juridical act circulate concurrently. Article 1369, in its electronic-form alinéa, expressly authorises authentic acts (acte authentique) on electronic medium provided they are established and preserved under conditions fixed by Conseil d’État décret; when received by a notary, the authentic act on electronic medium is exempt from any handwritten mention otherwise required by statute. The Conseil d’État conditions for notarial electronic authentic acts are set by Décret n° 2005-973 du 10 août 2005 (modifying Décret n° 71-941 relatif aux actes établis par les notaires), which the acte authentique électronique (AAE) infrastructure relies on.

Décret 2017-1416 — Implementation of the QES Presumption

Décret n° 2017-1416 du 28 septembre 2017 is the Conseil d’État décret to which Article 1367 alinéa 2 refers. Its Article 1 abrogates the prior Décret n° 2001-272 du 30 mars 2001 and crystallises the rule that the reliability of an electronic signature process is presumed, until proof to the contrary, when that process implements a qualified electronic signature. A qualified electronic signature, for these purposes, is an advanced electronic signature within the meaning of Article 26 of eIDAS, created using a qualified electronic signature creation device (“QSCD” — dispositif de création de signature électronique qualifié) meeting the requirements of Article 29 of eIDAS, and supported by a qualified certificate for electronic signature meeting the requirements of Article 28 of eIDAS. The décret therefore plugs French private-law evidentiary effects directly into the eIDAS QES architecture: a signature that is QES under Article 3(12) eIDAS automatically benefits from the Article 1367 alinéa 2 reliability presumption in French civil litigation. Lower signature tiers — eIDAS simple and advanced electronic signatures — remain admissible under Article 1366, but without the rebuttable presumption: the party relying on the signature must affirmatively prove identification and integrity rather than benefiting from a statutory presumption that the opponent must dislodge.

ANSSI — Supervisory Body and Trusted List

The Agence nationale de la sécurité des systèmes d’information (ANSSI) is the national supervisory body designated under Article 17 of eIDAS in conjunction with Décret 2017-1416 and earlier instruments establishing its competence over State information-system security. ANSSI assesses qualification dossiers submitted by candidate qualified trust service providers, conducts supervisory audits in cooperation with conformity-assessment bodies accredited by the Comité français d’accréditation (Cofrac) under Annex II of eIDAS, and signs and publishes the French segment of the EU Trusted List required by Article 22 of eIDAS — that segment is then aggregated by the European Commission into the consolidated EU Trusted List displayed via the Trusted List Browser. ANSSI also maintains the public catalogue des produits et services qualifiés on cyber.gouv.fr, which lists qualified electronic-signature-creation devices, qualified certificates, qualified time-stamps, qualified electronic-registered-delivery services, and the corresponding qualified providers (such as Certinomis, ChamberSign, Universign, Docaposte and others active on the French market), together with the scope and validity period of each qualification. Removal from the catalogue terminates the QES status of certificates issued thereafter.

Blockchain Anchoring

The Code civil and Décret 2017-1416 are technology-neutral by design — eIDAS Recital 27 captures the general principle, and nothing in the French implementation departs from it. Anchoring a document hash to a public or permissioned distributed ledger satisfies the integrity condition of Article 1366 Code civil and the equivalent integrity element of Article 26(d) eIDAS for an Advanced Electronic Signature: once a hash is committed to a chain whose ordering is secured by a sufficient number of independent validators, any subsequent change in the underlying document changes the hash and is therefore detectable. Combined with proper signatory identification, blockchain anchoring can therefore form part of an AES that is fully admissible under Article 1366 and Article 1367 alinéa 1, valued by the trial judge under the libre appréciation des preuves. A Qualified Electronic Signature is a different question: the Article 1367 alinéa 2 reliability presumption attaches only to a QES within the meaning of Article 3(12) eIDAS, which requires that the signing key reside in an ANSSI-listed QSCD and that the corresponding certificate be issued by an ANSSI-listed Qualified Trust Service Provider. A self-custodied wallet — however cryptographically robust — does not on its own produce a French QES. France has separately recognised distributed-ledger registers in defined sectoral contexts: Ordonnance n° 2017-1674 du 8 décembre 2017 introduced the dispositif d’enregistrement électronique partagé (DEEP) regime for the registration and transfer of certain unlisted financial securities, and Loi PACTE n° 2019-486 du 22 mai 2019 consolidated the regulatory framework for digital-asset service providers — but these texts neither modify the QSCD requirement of Article 1367 nor extend the QES reliability presumption to on-chain signatures.

Notable Judicial Precedents

The Cour de cassation has addressed the evidentiary regime of electronic writing under articles 1366 and 1367 in Cass. civ. 1, 11 juillet 2018, pourvoi n° 17-10.458 (Publié au bulletin), which is the canonical post-reform reference cited by the 117e Congrès des notaires report on the probative force of electronic signatures and by subsequent commercial-chamber decisions. The case concerned a sports agent’s mandate exchanged by email; the Court held that the writing condition for the validity of certain juridical acts may be satisfied by an electronic exchange provided that the conditions of Article 1366 are met, and that the absence of a strictly compliant electronic signature does not necessarily defeat the écrit requirement when the trial court finds, on the facts, that identification and integrity are sufficiently established. The decision is instructive because it crystallises the practical operation of articles 1366 and 1367 alinéa 1 — equivalence with paper plus the general signature definition — independently of the QES reliability presumption of alinéa 2 and Décret 2017-1416. Subsequent decisions (notably Cass. civ. 1, 7 octobre 2020, n° 19-18.135 Publié au bulletin) have continued to apply the same framework.
