Commercial contracts qualify as written if they are signed with a handwritten signature. If the contract is in electronic form, it has an equal legal effect to a written legal statement if it is signed with a qualified electronic signature (QES). 

As a rule, commercial contracts must be in written form only when this is legally required. Among others, examples include: powers of attorney, commercial proxies, leasing agreements, agreements on the acquisition of debt, a statement by a guarantor in a guarantee agreement, agreements on the assignment of economic copyrights, and exclusive licensing agreements. 

This means that a QES must be used if the written form is mandatory under the law, i.e. in the aforementioned cases.

However, an AES, SES and other forms of electronic signature can be used for any other commercial contracts where a written form is not required.

4. Main and relevant court practices

Pursuant to the doctrine and practice of the Polish courts, only documents in an electronic form which are signed with a qualified electronic signature can be deemed legally binding written documents if the law requires a (simple) written form.

5. In which cases are documents only with wet ink signatures accepted?

If the law requires a notarial deed, the contract cannot be signed electronically even with a QES. An example being sale agreements obliging the transfer of ownership, and substantive legal documents granting the right for entry in the land and mortgage register, as well as agreements on easements, pledges, mortgages, usufruct, and cooperative ownership rights to premises, where wet-ink signatures are mandatory.
