Yes.
If so, what are they? Are these only notarial acts or also acts of other authorities?
According to Article 269 of the Romanian Civil Procedure Code, an authentic instrument is a document which has been formally drawn up or which has been registered and authenticated by a public authority, by a notary or by another person vested with public authority by the State, in the form and under the conditions set out by the law. The authenticity of the document refers to the identification of the parties, to the recording of the consent of the parties with regard to the content of the document, to the signature of the parties and to the date of the document. Pursuant to paragraph 2 of the same article, any other document issued by a public authority that the law deems authentic shall be an authentic document.
Therefore, not only notarial documents are authentic documents, but also other documents issued by other authorities which meet the criteria set out above, e.g., documents issued by courts, by the civil registry, etc.
