Yes.

If so, what are they?

All acts received and signed by a Notary in Malta are deemed authentic instruments, as they are Notarial Acts drawn up and/or received by notaries who are charged by law to receive acts inter vivos and wills, and to attribute public faith thereto, as defined in Article 2 of the Notarial Profession and Notarial Archives Act, Chapter 55 of the Laws of Malta.

Are these only notarial acts or also acts of other authorities?

All original acts issued by the Public Registry, the Land Registry, Court Registries, the Registrar of Companies, and other such and similar official registers are deemed authentic instruments as they are issued by a competent authority empowered for that purpose by the laws of Malta.

Under the Maltese legal system an authentic act has an enhanced probative value in comparison with other documents in the sense that it is proof of its own contents. A notary public, upon signing and finalising an authentic act attributes public faith to that authentic act. This results from Article 2 paragraph (1) of the Notarial Profession and Notarial Archives Act Chapter 55 of the Law of Malta which states:

Notaries are public officers. They are charged to receive acts inter vivos and wills, and to attribute public faith thereto; they shall be responsible for their custody and shall give out copies and extracts of or from such acts or wills.

• The date on which the authentic instrument was drawn up
• The place where the authentic instrument was drawn up
• The signature by the parties of the authentic instrument
• The parties’ declarations
• Appearance, identification and consent of the parties

Before which authority: Courts of Law

According to which procedure (state the applicable rules):
An authentic act is proof of its own contents, however it may still be contested in a Court of Law. The contestation can be made on various grounds, such as that consent of one of the parties was vitiated or that the one of the parties did not have capacity to contract.

Within what timeframe:
No action for the nullity or annulability of a Notarial Act can be brought about after the lapse of ten or five years respectively, from when the act is registered in the Public and/or Land Registry.
