1. In your legal system, are there acts which fall within the notion of an authentic instrument as defined in the European Union regulations?<br>[‘authentic instrument’ means a document which has been formally drawn up or registered as an authentic instrument in a Member State and the authenticity of which: <br>(I) relates to the signature and the content of the authentic instrument; and <br>(II) has been established by a public authority or other authority empowered for that purpose by the Member State of origin.]

Yes.

If so, what are they? Are these only notarial acts or also acts of other authorities?

In accordance with Paragraphs (1) and (2) of Article 323 of Act No. CXXX of 2016 on the Code of Civil Procedures, any paper-based or electronic document which has been issued in accordance with the relevant statutory provisions by a court, a notary or another authority, or an administrative body within its sphere of authority shall be construed an authentic instrument.

An authentic instrument shall be treated genuine until proven to the contrary; the court, however, may call upon the issuer of the document of its own motion to provide a statement as to the authenticity of the document.

Therefore, besides the acts of the Hungarian notaries, the acts (decisions) of the courts, bailiffs, administrative bodies (e.g. municipalities), etc. are also considered as authentic instruments.
