The Notaries Public Act (Cap 208) expressly provides that every notary public shall have and may exercise within Singapore all powers and functions which are ordinarily exercised by notaries public in England. Without prejudice to the generality of the powers and functions, the practical functions of a notary public follow those applicable in England, with some variations, and are principally as follows: -

a) administer any oath or affirmation in connection with any affidavit or statutory declaration which is executed-

i) for the purpose of confirming or proving the due execution of any document;

ii) by any master or member of the crew of any vessel in respect of any matter concerning the vessel; or

iii) for the purpose of being used in any court or place outside Singapore;

b) take or attest any affidavit or statutory declaration referred to in (a).

These shall not include the power to administer any oaths or affirmation in connection with any affidavit or statutory declaration which is executed for the purpose of being used in any court or place within Singapore.

In a nutshell, a notary public's duty is to attest deeds, contracts, and other instruments that are to be used abroad and to give a certificate of the due execution of such documents duly authenticated by his signature and notarial seal.

Unlike commissioners for oaths, a notary public is in a position to witness a document signed in front of him which is in a foreign language. It is essential for the notary public to remember that he is witnessing and attesting to the identity of the signature, not the validity of the contents of the document. However, it is prudent for a notary public to only witness a document in an English equivalent thereof translated by an official interpreter, and the deponent signs both, and he so deposes and attests in his notarial certificate.
