In the rapidly evolving business landscape of 2026, the transition to a paperless environment is no longer a luxury—it is a strategic necessity. Whether you are an entrepreneur launching a startup in the heart of Warsaw or a multinational corporation expanding across Poland, the ability to authenticate documents remotely with full legal validity is paramount.
Lex Corporation, a premier business consultancy in Warsaw, is proud to be an authorized partner and reseller of Certum by Asseco Data Systems S.A. We provide comprehensive support in obtaining and implementing the most trusted digital authentication tools on the market: the Qualified Electronic Signature, SimplySign, and e-Doręczenia.
Why Choose a Qualified Electronic Signature?
A Qualified Electronic Signature (QES) is the digital equivalent of a handwritten signature. Under the EU eIDAS Regulation, a qualified signature carries the same legal weight as a traditional pen-and-paper signature. This means it is recognized not only by Polish administrative offices but across all European Union member states.
The Core Benefits:
- Legal Equivalence: Fully compliant with Polish law and EU regulations.
- Security: Advanced cryptographic technology ensures that the document cannot be altered after signing.
- Efficiency: Eliminate the need for printing, scanning, and physical archiving.
- Mobility: Sign contracts, tax declarations, and official applications from anywhere in the world.

As an authorized Certum Partner Point, Lex Corporation acts as your local hub for digital trust services. Certum, operated by Asseco Data Systems, is the largest and oldest certification center in Poland, boasting over 20 years of experience and more than 1 million issued signatures.

Frequently Asked Questions (FAQ)
1. Can a foreigner obtain a qualified electronic signature in Poland? Yes. Foreigners can obtain a QES using a valid passport or an EU ID card. You do not strictly need a PESEL number to have a signature, though it is highly recommended for easier interaction with Polish tax (e-Deklaracje) and social security (Płatnik) systems.
2. How long does the process take? At Lex Corporation, we offer an express service. If all documents are in order, we can often complete the identity verification and issue the certificate within 30 to 60 minutes.
3. Is SimplySign secure? Absolutely. SimplySign uses two-factor authentication (2FA) and is audited by the National Certification Center (NCCERT). It meets the highest security standards set by the eIDAS regulation.
4. Can I use my Certum signature for KSeF? Yes. For sole proprietorships (JDG), a qualified signature is sufficient. For larger companies, Lex Corporation also provides Qualified Electronic Seals, which allow for automated, entity-level authentication of invoices in the KSeF system.
5. Do I need to renew my signature? Yes, qualified certificates are issued for a fixed term (usually 1–3 years). Lex Corporation tracks your expiration date and assists with the renewal process to ensure your business continuity is never interrupted.
