A qualified electronic signature is a type of electronic signature that has the same legal validity as a handwritten signature. It is created using a qualified certificate that verifies the identity of the person signing a document.
Because the signer’s identity is confirmed through the qualified certificate, documents signed in this way can be used in many situations where a handwritten signature would normally be required.

How Does a Qualified Electronic Signature Work?
A qualified electronic signature consists of two key elements:
- A qualified certificate that confirms the identity of the signer.
- A secure signature creation method that protects the certificate and signing process.
When a document is signed, the signature is linked to both the document and the signer’s identity. If the document is modified after signing, the signature becomes invalid, making unauthorized changes detectable.
Qualified vs. Non-Qualified Electronic Signatures
Qualified Electronic Signature
- Has the legal effect of a handwritten signature.
- Uses a qualified certificate issued by a trusted certification authority.
- Can be used in many official, business, and administrative processes.
- Does not require separate agreements between parties to establish its validity.
Non-Qualified Electronic Signature
- Does not automatically have the legal effect of a handwritten signature.
- Is often used for internal document workflows and business processes.
- May require prior agreement between the parties involved.
- Is generally subject to fewer regulatory requirements.
Legal Framework
The issuance and use of qualified certificates are regulated by electronic signature legislation and applicable trust service regulations.
Because qualified electronic signatures can be used in legal and administrative procedures, certificate providers and signature creation tools must meet specific security and compliance requirements.
These requirements help ensure:
- The identity of the signer is verified.
- The certificate is protected against unauthorized use.
- Signed documents can be validated reliably.
Practical Applications
Qualified electronic signatures are commonly used for:
- Signing contracts and agreements
- Submitting documents to public institutions
- Corporate document approval workflows
- Financial and legal transactions
- Electronic communication requiring a verified identity
Summary
A qualified electronic signature is an electronic signature backed by a qualified certificate that verifies the signer’s identity. It provides the same legal effect as a handwritten signature and is designed for situations where secure and legally recognized electronic document signing is required.
