Are electronic signatures legally valid in Germany?
Yes. No court in the EU may reject a signature solely because it is electronic. Whether it is enough for your document depends on the form requirement, and what it proves in court depends on the signature level and the documentation. You will find both here, with the statutes quoted word for word.
Yes, throughout the EU. Under the EU eIDAS Regulation, electronic signatures may not be denied legal effect solely because they are electronic (Art. 25 (1) eIDAS).
For which contracts?
For all contracts with no form requirement, and that is the vast majority. Since 2025, also for many cases in which the law now only requires text form (Textform).
Written form?
If the law requires the statutory written form (Schriftform), only the qualified electronic signature (QES) will do. It replaces the handwritten signature (§ 126a BGB, German Civil Code).
What does not work?
Declarations for which the law excludes the electronic form, such as a guarantee (Bürgschaft) given by a private individual (§ 766 BGB), and anything that requires notarial recording (notarielle Beurkundung).
In court?
The court freely assesses SES and AES, and the audit trail is decisive. For the QES, there is a presumption of authenticity (§ 371a ZPO, German Code of Civil Procedure). German sources call the three levels EES, FES and QES.
Legally valid and provable are two different questions
When people ask whether an electronic signature is valid, they usually mean both at once. Legally, these are two separate tests, and different things count for each.
Is the contract valid?
Decided by: the form requirement
Most contracts have no form requirement, and any electronic signature is enough for them. If the law prescribes a form, the signature must meet that form. If it does not, the legal transaction is generally void (§ 125 BGB).
If someone denies having signed, it comes down to proof. The better the identity is secured and the more complete the record of the signing process, the stronger your position in court.
From contracts with no form requirement to notarial deeds: the stricter the form, the higher the signature level. The last two steps cannot be met electronically at all.

The minimum level is what the law requires. Where a dispute is likely or a lot of money is at stake, going one level higher often pays off. Not legal advice for individual cases.
The legal basis, word for word
Seven provisions carry the entire legal framework. Here is their wording, the EU regulation in its official English version and the German statutes in an unofficial translation, each with what it means for your contracts.
An electronic signature shall not be denied legal effect and admissibility as evidence in legal proceedings solely on the grounds that it is in an electronic form or that it does not meet the requirements for qualified electronic signatures.
Every signature level has legal effect and is admissible in court, throughout the EU.
If the written form prescribed by law is to be replaced by the electronic form, the issuer of the declaration must add their name to it and provide the electronic document with their qualified electronic signature.
In Germany, the electronic form means: name plus QES.
If text form is prescribed by law, a legible declaration in which the person making the declaration is named must be made on a durable medium.
Text form requires no signature at all, so an SES is always enough.
§ 371a (1) sentence 2 ZPO (unofficial translation) Statute text
The prima facie evidence of the authenticity of a declaration in electronic form that results from verifying the qualified electronic signature […] can only be shaken by facts that give rise to serious doubt that the declaration was made by the person responsible for it.
With the QES, the other side has to cast doubt on its authenticity; you do not have to prove it.
What counts in court
Legally valid does not yet mean proven. If the other side disputes the signature, what matters is the level and how the signing process was documented.
SES
Free assessment of evidence (§ 286 ZPO)
Whoever relies on the signature must prove that it is authentic. The audit trail is the most important evidence.
AES
Free assessment of evidence, strong indications
The second factor, such as the SMS code sent to the mobile number, clearly links the signature to the signer and makes any denial harder.
QES
Presumption of authenticity (§ 371a ZPO)
Authenticity is presumed. Whoever disputes it must present specific facts that give rise to serious doubt.
From case law
The LAG Berlin-Brandenburg (Regional Labor Court) held the fixed term of an employment contract invalid because the employer had only used a scanned signature. A scan is neither handwritten nor a QES and does not meet the statutory written form under § 14 (4) TzBfG, the Part-Time and Fixed-Term Employment Act (judgment of March 16, 2022, 23 Sa 1133/21).
What robust evidence includes
The signed PDF, sealed so that any later change is detectable
Timestamps for sending, opening and signing, for every person
The email address to which the personal signing link was sent
For the AES, proof of the second factor, such as the SMS code
A completion certificate that brings all the data together in one document
What has changed since 2025
Lawmakers are dismantling form requirements. For many documents, a simple electronic signature is now enough where a QES used to be needed.
Text form instead of written form
The Fourth Bureaucracy Relief Act (Viertes Bürokratieentlastungsgesetz) lowers the form for commercial leases of more than one year, temporary agency work, the statement of employment terms and agreements on the standard retirement age to text form. Employment references are possible electronically with consent, by QES.
Consumer credit in text form
Text form is enough for general consumer credit agreements. Pre-selected options are not enough for consent. Real estate consumer credit agreements still require the statutory written form.
EU Digital Identity Wallet
All EU member states are to offer a digital identity wallet that lets natural persons create qualified signatures free of charge for non-professional purposes (Art. 5a (5) (g) eIDAS).
Yes. The eIDAS Regulation applies directly throughout the EU: an electronic signature may not be denied legal effect solely because it is electronic (Art. 25 (1) eIDAS). That is why any electronic signature is enough for all contracts with no form requirement. Only where the law requires the statutory written form do you need the qualified electronic signature (§ 126a BGB).
Only the qualified electronic signature has the same legal standing (Art. 25 (2) eIDAS). Simple and advanced signatures are still fully effective as long as the law does not prescribe the statutory written form, and that is the case for most contracts.
In two cases. First, when the law excludes the electronic form, for example for the termination of an employment relationship (§ 623 BGB), a guarantee given by a private individual (§ 766 BGB) or an acknowledgment of debt (§ 781 BGB). Second, when notarial recording is required, for example for a real estate purchase (§ 311b BGB).
For contracts with no form requirement, yes: the scan is a simple electronic signature, though with weak evidential value. If the law requires the statutory written form, a scan is not enough: the LAG Berlin-Brandenburg held a fixed term with a scanned signature to be invalid (23 Sa 1133/21).
With simple and advanced signatures, the party relying on the signature. The court assesses the evidence freely (§ 286 ZPO), and a complete audit trail is decisive. With the qualified signature, there is a presumption of authenticity, and the other side must establish serious doubt (§ 371a ZPO).
Yes. Art. 25 (1) eIDAS applies in all member states, and a qualified electronic signature based on a qualified certificate issued in one member state is recognized as a QES in all other member states (Art. 25 (3) eIDAS). Which form a contract requires depends on the applicable national law.
Not for contracts with no form requirement; each party can use a different level. If the law requires the statutory written form and it is met electronically, all parties must sign an identical document with a qualified electronic signature (§ 126a (2) BGB).
Statutory written form (Schriftform, § 126 BGB) requires a handwritten signature or, as the electronic form, a QES. Text form (Textform, § 126b BGB) only requires a legible declaration on a durable medium that names the person making it; no signature is needed. So any electronic signature is enough for text form.
