If a document requiring notarisation is in a foreign language it may be necessary for the document to be translated by an official translator who will then have to sign a statutory declaration certifying that it is a true translation.In some cases the Notary may be able to watch the signing of a foreign document and then prepare a covering certificate to which he will fix his seal of office and signature to confirm that he has witnessed the signing and checked identity. The Notary must be completely satisfied that the person signing is fully conversant with the language of the document and has been properly advised on its contents.
