What’s the difference between a notary public and a commissioner of oaths?
A commissioner of oaths (or a commissioner for oaths) is someone authorised by law to take oaths, affirmations, and declarations from people swearing to the truth of certain documents or for certifying true copies of documents for legal purposes. In New South Wales, this role is usually performed by a justice of the peace.
If you must sign a document that requires a ‘prescribed witness’ or you must certify a copy of your original document, then you can usually use a justice of the peace, a lawyer, or a notary public. However, if you have been told that your document must be signed in front of a commissioner of oaths, it is probably because your document will be used in another country (or in another state other than New South Wales) where they have commissioners of oaths. If your document is going to be used in another country, then your document will likely need to be notarised by a notary public instead of being attested by a commissioner of oaths, justice of the peace, or a lawyer (who is not a notary public).
In Australia, a notary public is a senior lawyer who has completed further qualifications to be appointed as a notary public. A notary public, like a commissioner of oaths, is authorised by law to take oaths, affirmations, and declarations from people swearing to the truth of certain documents or for certifying true copies of documents for legal purposes.
The important difference between a notary public from a justice of the peace, a commissioner of oaths, or any other prescribed witness is that if a document is intended to be used in another country then it should be notarised which can only be done by a notary public. On the other hand, if you are using your document in Australia, then you can use a justice of the peace.
If your document must also be stamped with an apostille or authenticated by the Department of Foreign Affairs and Trade (DFAT), then your document must be notarised by a notary public. DFAT will not recognise documents attested by a commissioner of oaths, justice of the peace, or a lawyer (who is not a notary public).
The fact that you are asking this question or searching for answers and you are now reading this page suggests that someone has asked you to use a commissioner of oaths or you are sending your documents overseas which means you will need to use a notary public to notarise your documents.
