Digital signature Liechtenstein: eIDAS/EEA-compliant electronic signature
actaSIGN is the signature platform for businesses in Liechtenstein that want to sign contracts electronically and digitally with legal validity. The solution supports SES, AES and QES within the eIDAS/EEA framework, respects Liechtenstein's Signature and Trust Services Act (SigVG), and offers Swiss hosting from the Sargans region.
Short answer
Is a digital or electronic signature legally valid in Liechtenstein?
Yes. In everyday use, digital signature and electronic signature are often used synonymously; Liechtenstein is an EEA member and applies the eIDAS framework for electronic signatures and trust services.
The Signature and Trust Services Act (SigVG) complements this framework nationally. SES or AES is sufficient for many form-free contracts; where written form matters, QES is the strongest signature level.
actaSIGN is especially close for businesses in Liechtenstein: axelity ag is based in Sargans, Swiss hosting stays next door, and regional partners support integration.

Legal framework for electronic signatures in Liechtenstein
As an EEA member, Liechtenstein applies the eIDAS framework. The Signature and Trust Services Act (SigVG) and national form requirements complement it.
eIDAS Regulation (via EEA)
The eIDAS Regulation was adopted into Liechtenstein law via the EEA Agreement. All three signature qualities (EES, AES, QES) are recognised.
SigVG — Signature and Trust Services Act
SigVG governs national supervision and implementation for electronic signatures and trust services. The Office for Communications is the competent authority.
Form requirements and regional proximity
Freedom of form applies to many business processes. Where written form is required, QES is relevant. actaSIGN combines this legal framework with Swiss hosting right next to Liechtenstein.
Which signature level fits in Liechtenstein?
The right signature level depends on risk, evidentiary need and possible form requirements.
| Signature level | When sufficient? | When QES? | Typical examples |
|---|---|---|---|
| SES — simple electronic signature | For simple, form-free internal or external processes with low risk. | Not suitable where written form must be replaced electronically. | Internal approvals, simple confirmations, operational documents. |
| AES — advanced electronic signature | For many form-free business documents with higher evidentiary needs. | Not sufficient for processes where written form is explicitly required. | NDAs, mandate agreements, supplier contracts, HR documents. |
| QES — qualified electronic signature | When maximum evidentiary value or a written-form requirement is decisive. | Strongest signature level in the eIDAS/EEA framework. | Compliance-relevant contracts, finance and trust documents, high-value agreements. |

Digital signature or electronic signature — what's the difference?
In Liechtenstein the terms are often used interchangeably. Via the EEA Agreement, eIDAS applies — legally relevant is the "electronic signature" with its three quality levels (SES, AES, QES). A "digital signature" strictly refers to the underlying cryptographic technique. For legal validity, what matters is the signature quality, not the wording.
