An Australian loan with an Australian lender almost never involves a notary. The lender identifies you itself, and any mortgage is handled through its own systems and your conveyancer or lawyer. When a notary does appear in a loan, it is because one side of the transaction is overseas.
The common situations are:
In each case the foreign party cannot see you sign and cannot check an Australian identity document. A notary's certificate, usually with an apostille, answers both problems.
If the other party is in Australia and the lender is Australian, ask why a notary has been requested. A domestic loan rarely needs one.
Bring the agreement unsigned, every page, along with photo identification (a passport is safest) and any instructions the lender has given about how it wants the document executed.
The notary will:
The notary does not review the terms. A notarial certificate says who signed and when. It says nothing about whether the interest rate is fair, whether the security is enforceable, or what the lender's country's law makes of the document. For those questions, you need a lawyer, ideally in the lender's country.
A document in a language you do not read raises a particular problem, because the notary must be satisfied you understand what you are signing. Expect to need a translation. Our page on notarising documents in a language you do not read explains the options.
A guarantee is where the notary's checks on capacity and free will matter most. Guarantees for family members are signed under pressure more often than any other document, and a guarantor can end up liable for the whole debt.
Expect the notary to speak with you on your own, to ask whether you understand the extent of your liability, and possibly to ask whether you have had independent legal advice. A notary who is not satisfied may decline to act. That protects you as much as the lender.
Some foreign lenders also require a certificate that the guarantor has received independent legal advice. That comes from a lawyer who advises you, not from the notary witnessing your signature. Before signing any guarantee, especially one secured over your home, see a lawyer.
If a company is the borrower, lender or guarantor, the notary will usually need evidence that the people signing are authorised to bind it: company records and often a board resolution approving the transaction. Some foreign lenders also want the notary to certify the company's existence and the signatories' authority. See our pages on notarising for a company and notarising a board resolution.
After signing, keep a complete copy. If the agreement later has to be produced to a foreign court, registry or tax authority, a notary can certify a copy after sighting the signed original. If the original went to the lender, ask it for a certified copy from its own records, or keep a notarised copy made at the signing appointment.
Only DFAT issues apostilles in Australia; a notary cannot.
Some countries require security documents, such as mortgages over their land, to be signed before their own notary or at their consulate rather than before an Australian notary. Ask the lender or its lawyer before booking anything, because a document signed the wrong way may have to be signed again.
Notarial fees are not set by statute and vary between practitioners. As a market estimate only:
Long agreements with every page initialled, several signatories, or company authority certificates take longer and cost more. DFAT and embassy fees are separate and charged per document.
Can I sign first and bring it to the notary later? Usually not. The notary witnesses the signature being made. Our page on what to do when the document is already signed covers the options.
Does notarising make the loan enforceable? No. It proves who signed. Enforceability depends on the agreement and the law that governs it.
Can a Justice of the Peace witness it? For a document going overseas, generally not. A JP is not recognised abroad and a JP-witnessed document cannot be apostilled.
