Yes.
If so, what are they? Are these only notarial acts or also acts of other authorities?
According to the provisions of § 205 Civil Code for contentious procedures (160/2015), documents issued by public authorities within their powers and documents declared by special regulations as being public (for example notarial act, birth certificate, marriage certificate, etc.) shall confirm, unless the contrary is proven, that testimonials and confirmations included in such documents are accurate.
Therefore, besides the acts of Slovak notaries, the acts of the courts (except court decisions falling under the EU definition of “decision”), bailiffs, administrative bodies (e.g. municipalities), etc. are also considered as authentic instruments.
