E-signature legality in Poland
Polska
Poland recognises e-signatures under eIDAS and the 2016 Trust Services Act.
The law in plain language
Poland's Act of 5 September 2016 on Trust Services and Electronic Identification implements eIDAS. Electronic signatures are admissible in Polish courts; qualified electronic signatures have the legal force of handwritten signatures.
- Primary framework
- eIDAS + Ustawa o usługach zaufania oraz identyfikacji elektronicznej
- National act
- Ustawa z dnia 5 września 2016 r. o usługach zaufania oraz identyfikacji elektronicznej
Signature tiers recognised in {country}
Poland recognises the three eIDAS-aligned tiers. The right tier depends on the contract — most B2B documents are fine with SES; AES adds an identity-binding factor; QES carries the legal force of a handwritten signature for documents that require written form.
The baseline — admissible as evidence in court. Suitable for everyday commercial contracts.
SES + a second factor (typically SMS) that uniquely binds the signature to the signer.
AES + a qualified certificate from a Qualified Trust Service Provider. Equivalent to a wet signature.
Routinely signed electronically
- B2B service agreements, SaaS contracts, supplier MSAs
- NDAs, sales orders, partner agreements
