Electronic Signature of Certum

In an age where business is increasingly digital, organizations need ways to sign documents that are fast, secure, and fully compliant with the law. Through our partnership with Certum, we provide clients with a reliable electronic signature service that combines convenience with the highest standards of data security.
What Is an Electronic Signature?
An electronic signature is the digital equivalent of a handwritten signature. It is a set of electronic data that is attached to or logically associated with a document, allowing the signer to confirm their identity and intent.
Unlike a scanned signature image, a true electronic signature uses cryptographic technology to ensure:
 Authenticity – Proof that the signature belongs to a specific person.
 Integrity – Proof that the document has not been altered after signing.
 Non-repudiation – The signer cannot later deny their involvement.
Certum’s electronic signatures are fully compliant with the EU eIDAS Regulation and the Polish Act on Trust Services and Electronic Identification, ensuring they are recognized in all EU member states.

Types of Electronic Signatures
Certum offers three levels of electronic signatures, each with different security and legal implications:

  1. Simple Electronic Signature – Basic identification; suitable for low-risk transactions.
  2. Advanced Electronic Signature – Uniquely linked to the signer and detects any changes to the signed data.
  3. Qualified Electronic Signature (QES) – Created using a secure device and a qualified certificate issued by Certum; legally equivalent to a handwritten signature in the EU.
    When Is an Electronic Signature Valid?
    A Qualified Electronic Signature from Certum holds the same legal power as a traditional signature for most contracts and official documents, such as:
     Employment contracts
     Service and sales agreements
     Non-disclosure agreements
     Licensing and copyright transfers
     Real estate brokerage agreements
     Lease agreements
    Some legal acts — such as company formation agreements, property transfer deeds, or wills — still require a handwritten signature, but for most day-to-day business, a QES is sufficient.
