The notary performs notarial activities pursuant to the provisions of the Polish law. Pursuant to Article 2 § 3 of the Act on Notarial Services, notarial activities are performed in Polish language. At the request of a party, the notary may additionally perform this activity in a foreign language, using his or her own knowledge of a foreign language certified in a manner specified for sworn translators or with the help of a sworn translator.

If a foreigner who does not have a command of Polish language is a party to a notarial activity, assistance of a sworn translator is necessary.

Preparatory activities may take place without the assistance of a sworn translator.
