Understanding the Three Different Types of Electronic Signatures in Germany

In today's digital world, electronic signatures (e-signatures) have become a fundamental part of streamlining business processes. Whether you’re signing a simple document or a legally binding contract, understanding the different types of e-signatures and their legal validity is crucial. In Germany and across the EU, e-signatures are regulated by the eIDAS Regulation (EU Regulation No. 910/2014), ensuring their compliance and legal recognition.

This guide breaks down the three main types of electronic signatures used in Germany, their applications, and how they can be effectively implemented in practice.

What Are the Different Types of Electronic Signatures?

The three types of electronic signatures recognised under eIDAS vary by their level of security, legal validity, and use cases. Each type serves specific purposes, depending on the legal risk and level of assurance required. Let’s talk about these types in detail:

1. Simple Electronic Signature (SES)

A Simple Electronic Signature (SES) is the most basic form of e-signature. It can take many forms, such as:

• Typed name or ticked box
• Scanning and attaching an image of a handwritten signature
• Clicking an "Accept" button on a website or form

Legal Standing:
The SES is often used in low-risk situations, where legal disputes are rare. Although it is admissible as evidence in legal cases, it does not offer the highest level of security or certainty about the signer’s identity.

Practical Uses:
SES is ideal for internal documents, informal agreements, and transactions with low legal risk. For example, it can be used for approving internal policies or minor procurement agreements.

2. Advanced Electronic Signature (AES)

An Advanced Electronic Signature (AES) offers a higher degree of security and verification compared to SES. According to eIDAS, an AES must meet four specific criteria:

• It is uniquely linked to the signatory.
• It can identify the signatory.
• It is created using electronic signature data that only the signatory controls.
• Any subsequent changes to the signed data must be detectable.

Typically created through cryptographic methods, the AES ensures that the signer’s identity is secure, and any alterations to the signed document are immediately visible.

Legal Standing:
An AES is considered valid evidence in court and is often used in situations where medium levels of legal risk exist. It provides stronger guarantees compared to SES, but it’s not as legally binding as a qualified signature (QES).

Practical Uses:
This type of signature is suitable for medium-risk contracts, such as permanent employment agreements, B2B sales agreements, or cross-border transactions. For instance, companies engaged in international business often use AES to ensure that agreements are secure and compliant with multiple jurisdictions.

3. Qualified Electronic Signature (QES)

The Qualified Electronic Signature (QES) represents the highest standard of e-signatures under eIDAS. It is essentially an advanced signature that includes additional measures to ensure the signer's identity. A QES must:

• Be created using a qualified electronic signature device
• Be based on a qualified certificate issued by a trusted service provider.

A QES is legally equivalent to a handwritten signature and is required by law for certain high-risk transactions.

Legal Standing:
The QES holds the strongest legal recognition, making it the only e-signature that can fully replace a handwritten signature in regulated industries like finance, healthcare, or labour law. It is mandatory for transactions involving high legal risk, such as notary services or long-term employment contracts.

Practical Uses:
This signature is perfect for high-stakes transactions, such as entering into complex financial agreements or regulatory filings. For example, the QES is often used in situations where personal identity verification is legally required, like signing loan agreements or establishing power of attorney.

How Are E-Signatures Applied in Practice?

With the help of modern legal management platforms like GAIA, signing a document digitally has become a seamless experience. Here’s how the process works:

1. The signatory receives an email containing a link to the document.
2. After clicking the link, the signatory is directed to a secure signing interface.
3. Depending on the pre-selected signature type (SES, AES, or QES), the platform guides the signatory through the relevant steps.
4. Real-time updates track the signing progress, and once all signatures are complete, the system securely stores the finalized document.

This streamlined process ensures that all parties can sign from anywhere, at any time, without compromising legal integrity.

Configuring Signature Settings in GAIA

Setting up the signature process in GAIA is simple and intuitive. Here’s a step-by-step guide:

1. Select "Send for Signature": Choose the document you want to send.
2. Adjust Signature Settings: Under "Signature Settings," pick the desired signature type—SES, AES, or QES.
3. Choose Signature Order:some text
   • Parallel: All signers can sign simultaneously.
   • Sequential: Each signer is prompted to sign one after the other.

By leveraging the right e-signature for your document, you can efficiently digitize your workflows while ensuring full legal compliance.

Conclusion

E-signatures have revolutionized how businesses handle document signing, offering flexibility, security, and legal assurance. Understanding the different types of electronic signatures—SES, AES, and QES—enables you to choose the most appropriate solution for your needs.

GAIA makes it easy to implement these e-signatures, ensuring your documents are signed quickly and securely, no matter the legal requirements.
