Sign loan agreements digitally in Germany: AES, QES and remote signatures

• Under Sections 491 and 492 of the German Civil Code (BGB), consumer loan agreements involving payment are, as a general rule, subject to the written form requirement.
• A biometric AES on a signature pad does not replace this written form; for this, a QES is required in electronic form.
• Remote signing enables the QES to be created without a card reader at the customer’s premises, directly as part of the online or in-branch process.
• In the physical branch, supporting documents can still be captured on the signature pad using signoSign/2 without the need to comply with the written form requirement.

Is a signature pad sufficient for digitally signing a loan agreement? In most cases, no. Under Section 492 of the German Civil Code (BGB), consumer loan agreements require the written form, which can only be validly replaced by a qualified electronic signature in accordance with the eIDAS Regulation. For banks and financial service providers, this means that the signature process for the actual loan agreement differs from that for accompanying documents such as the cancellation policy or SEPA mandate. However, not every loan agreement is subject to this requirement: if the customer pays neither interest nor any other costs, there is no consumer loan agreement in legal terms, and the written form requirement does not apply. This applies, for example, to some 0% finance schemes, which can then also be concluded using an advanced electronic signature (AES). The decisive factor here is not the advertised interest rate, but whether no fees are actually incurred.

Section 492(1) of the German Civil Code (BGB) generally requires consumer loan agreements for consideration to be in writing. The contracts covered are set out in Section 491 of the German Civil Code (BGB); interest-free loans and financial assistance are regulated separately in Sections 514 and 515 of the German Civil Code (BGB). Under Section 126(3) in conjunction with Section 126a of the BGB, this written form may be replaced by an electronic form – but only with a qualified electronic signature. In the past, courts have ruled that simple signatures captured on a tablet were insufficient for contracts requiring the written form if no qualified electronic signature (QES) was present. In the case of a consumer loan agreement requiring the written form, therefore, only a QES effectively replaces a handwritten signature.

A signotec signature pad captures the handwritten signature biometrically and embeds it verifiably into the PDF – this constitutes an advanced electronic signature (AES). For many banking documents without any statutory formal requirements, such as consultation records or internal memos, this is sufficient and significantly quicker than sending them by post. For the loan agreement itself, however, a QES is also required; this is issued by a qualified trust service provider and usually requires the customer to be identified, for example via video identification or eID.

Remote signature solves a practical problem: instead of a physical signature card with a card reader, the qualified certificate is held by the trust service provider, and the customer triggers the signature using a one-time password or an app. This makes the QES feasible even for online transactions, without customers having to apply for a hardware certificate in advance. For banks, this means that the loan application process can be carried out online seamlessly, from the application stage right through to the legally valid signature.

signoSign/Universal can be connected to trust service providers for remote signatures and integrated into existing lending systems. Different signature levels can be configured for each document type within the same workflow: QES for the loan agreement, AES for supporting documents. At the branch, signoSign/2 complements the process for all documents that do not require a QES, so that customer advisers do not have to switch between different systems.

Is an advanced electronic signature sufficient for a consumer loan?

In the case of a consumer loan agreement for consideration under Sections 491 and 492 of the German Civil Code (BGB), this is generally not the case. The statutory requirement for the written form can only be replaced electronically by a qualified electronic signature (QES). Separate rules apply to interest-free loans and financial assistance.

Does the customer have to visit the bank to provide a remote signature?

No, that is precisely the advantage of a remote signature: identification is usually carried out via video identification or eID, and the signature is then provided online using a one-time password or an app.

Does the written form requirement also apply to commercial loans?

Section 492 of the German Civil Code (BGB) relates to consumer loan agreements. Different formal requirements may apply to commercial loan agreements in some cases; this should be checked on a case-by-case basis.

What happens if a loan agreement is signed electronically without a QES?

If the required form is not met, the contract may be invalid or voidable. Banks should therefore clarify the formal requirements for each document type before switching to digital signatures.

Can the cancellation policy and the SEPA direct debit mandate be signed using a lower level of digital signature?

Often yes, as there is no statutory requirement for these to be in writing. However, the specific classification should still be checked on a document-by-document basis.

Does the written form requirement also apply to 0% financing?

Not necessarily. If the consumer pays neither interest nor any other costs, there is no consumer loan agreement within the meaning of Section 491 of the German Civil Code (BGB), and the written form requirement under Section 492 BGB does not apply. If, on the other hand, fees or other costs are incurred, the contract is for consideration despite the 0 per cent interest rate. Whether an offer is actually free of charge should therefore be assessed on a case-by-case basis.

In the case of digital credit agreements, the appropriate signature level depends on the specific contract. For a consumer loan agreement requiring written form and involving consideration, a QES is required if it is concluded electronically. For many supporting documents, a lower level is sufficient. With signoSign/Universal for remote signing and signoSign/2 for in-branch appointments, signotec covers both scenarios in a single, integrated process.
