Is an Electronic Signature Legally Valid in France? (2026)

The short answer is yes. In France an electronic signature is legally valid and can bind a contract for the great majority of agreements. France applies the European Union's eIDAS Regulation and has long recognised electronic signatures in its own Civil Code. French law places real weight on the reliability of the signature method, and it gives a special presumption to the highest-assurance form. This page explains the governing law, the three signature types, the presumption that matters, and what is excluded. It is general information, not legal advice. ## The law behind French e-signatures Two layers apply together. The first is the EU eIDAS Regulation (Regulation (EU) No 910/2014), which applies directly in France. It provides that an electronic signature is not denied legal effect simply because it is electronic, and it defines the three types of electronic signature used across the EU. The second is the French Civil Code (Code civil). Its provisions on proof recognise the electronic signature and give it the same evidential value as a handwritten signature where the method reliably identifies the signer and guarantees the link between the signature and the document. The Civil Code articles on the electronic signature, supported by a decree, set out how that reliability is assessed. <!-- [VERIFY] confirm current Code civil articles on the electronic signature (around articles 1366 and 1367) and the implementing decree before relying on specific article numbers. --> ## The three eIDAS signature types eIDAS defines three levels, all used in France: 1. Simple electronic signature (SES). The broadest category, such as a typed name, a scanned signature, or a click to agree. Suitable for most everyday contracts. 2. Advanced electronic signature (AES). Uniquely linked to and capable of identifying the signer, created under their sole control, and linked to the data so any later change is detectable. 3. Qualified electronic signature (QES). An advanced signature created by a qualified signature creation device and based on a qualified certificate from a qualified trust service provider. Under eIDAS it has the same legal effect as a handwritten signature across the EU. ## The presumption of reliability French law adds an important point. A qualified electronic signature benefits from a presumption of reliability: it is presumed to reliably identify the signer and to guarantee the integrity of the document, so the burden shifts to anyone who wants to dispute it. A simple or advanced signature can still be valid and used as proof, but it does not carry that automatic presumption, so the party relying on it may have to show the method was reliable if it is challenged. This is why, for high-value or high-risk documents, French practice often favours a qualified or at least an advanced signature: it makes the signature far easier to defend. ## What is excluded or needs special care As in other systems, some documents need more than an ordinary electronic signature or are kept out of electronic form: - Private deeds relating to family law and the law of succession, such as certain acts concerning wills and inheritance, have historically been treated with special formality.

• Documents requiring a notarised deed (acte authentique), such as many real estate transfers, must follow the notarial process, although notaries themselves can produce electronic authentic acts within their own secure system.
• Certain documents where a specific statute prescribes a particular form. Because these rules are specific, confirm the requirement for the exact document before assuming an ordinary electronic signature will work. <!-- [VERIFY] confirm the current list of acts excluded from electronic form under French law, especially in family and succession matters, before relying on it. --> ## When you should use a qualified signature Use a qualified electronic signature for high-value or high-risk contracts, when you want the presumption of reliability, when you need a signature with the same legal effect as handwriting across the EU, and when a counterparty or authority expects it. For ordinary commercial contracts where both sides clearly intend to sign, a simple or advanced signature is generally sufficient. ## How to keep a French e-signature defensible To make an electronic signature easy to defend, match the signature type to the stakes (a qualified signature for important documents), use a provider whose method reliably identifies the signer and protects document integrity, keep the certificate and audit trail, check that the document is not one reserved for notarisation or special form, lock the document after signing, and store the signed version safely. ## Keeping the signed document safe afterwards Signing is only the first step. Once a contract is signed it still has to be stored, tracked, and renewed, and a signed PDF sitting in someone's inbox is easy to lose.

See how it works. The guidance above stands on its own. ## Bottom line In France, electronic signatures are legally valid for the great majority of contracts under the EU eIDAS Regulation and the Civil Code rules on proof. A simple or advanced signature works for ordinary contracts, while a qualified electronic signature carries a presumption of reliability that makes it much easier to defend and gives it the same legal effect as handwriting across the EU. Notarised deeds and certain family and succession acts need special formalities. For those, confirm the exact requirement before you rely on an electronic signature.
