An Australian notary's seal is usually a round embossed or inked seal showing the notary's name, the words "Notary Public" and the place where they practise, such as a city and state. It appears on the notarial certificate beside the notary's signature, and often across the binding. There is no single national design, so seals vary from notary to notary.
A notarial seal identifies the notary and their office. Most Australian notaries' seals are circular, and the text around the edge typically includes the notary's full name and the words "Notary Public", with the place where the notary practises, such as "Sydney, New South Wales, Australia" or "Brisbane, Queensland, Australia". Some include an emblem or device in the centre, a reference to the jurisdiction, or other identifying details. The exact wording and design vary.
The seal is used together with the notary's signature, and neither is meant to stand alone. Foreign authorities look for both on the notarial certificate, and DFAT checks them against its records when adding an apostille. Our guide to what a notary public does explains the notarial certificate the seal belongs to.
Traditionally, notarial seals are embossed: a metal press raises the design into the paper, sometimes through a coloured paper wafer stuck to the certificate. Embossed seals are hard to copy convincingly and can be felt as well as seen, which is part of their value. Many notaries also use an inked stamp with the same details, which shows up clearly on photocopies and scans, where an embossed seal may barely register.
Some notaries use both on the same certificate, and some use a seal across the ribbon or staple that binds the pages, so that the binding cannot be undone without disturbing it. Neither method is more valid than the other in general; what matters to a foreign authority is that the seal is clear, genuine and matches the notary. Our guide to why notaries bind documents explains the binding.
The main place is the notarial certificate, next to or over the notary's signature, where it authenticates the certificate itself. Notaries also often place the seal, or their signature, on each page of the document, across the edges of the pages, or over the binding, so that every page is identified as part of the bundle. If DFAT adds an apostille, it is attached to the notarial certificate, and the apostille itself refers to the seal the document bears.
Justices of the Peace commonly use an ink stamp with their name, their JP registration number and the state, when they witness documents or certify copies. It can look official, but it is not a notarial seal, and a JP is not a notary. A JP's stamp shows that a volunteer domestic witness certified a copy or witnessed a signature for use in Australia. Most foreign authorities do not accept it, and DFAT cannot apostille a JP's signature. Our guide to notaries and JPs explains the difference.

| DFAT apostille | Yes | No |
Seals are one of the oldest features of notarial practice, going back centuries in the European and English traditions from which Australian notaries descend. In many legal systems, a document bearing a notary's seal is treated as a formal public act, and officials abroad are trained to look for one. A notarial certificate without a seal can look incomplete to a foreign registry or court, even where the signature is genuine.
The seal also works alongside modern safeguards. DFAT's apostille confirms the seal and signature, the binding ties the certificate to the document, and the notary's register records the act. Together, they make a notarised document something a foreign authority can rely on without knowing the notary personally.
Most foreign registries, courts and banks look for three things on an Australian notarised document: the notary's signature, the notary's seal, and, where required, a DFAT apostille or authentication attached to the notarial certificate. They may also check that the notarial certificate is in a form they recognise, that the pages are bound together, and that any translation covers the certificate and apostille. A clear, complete seal reduces the chance of questions, especially where officials are not familiar with Australian practice.
Where a notarial act is performed electronically, the notary's seal and signature are applied digitally, usually as part of a secure electronic signature that can be verified. Acceptance of electronic notarial acts varies widely between receiving bodies and countries, and many still expect a paper document with a physical seal. If a foreign body asks for a document "under seal", ask whether it accepts an electronic seal before relying on one. Our guide to whether a scanned notarised document is valid covers the related question of scans.
Embossed seals can be faint, particularly on thin paper or after scanning, and inked seals can smudge. A seal that a foreign authority cannot read may lead to questions, although the apostille, which states the seal the document bears, often resolves them. If a seal is badly illegible, contact the notary: they may be able to add a clearer impression or prepare a fresh certificate. Do not try to enhance or trace over a seal yourself. Our guide to an illegible notary seal covers what to do.
A seal alone does not prove much, because designs vary and any stamp can be copied. The reliable check is through DFAT, which holds records of Australian notaries' signatures and seals for the purpose of issuing apostilles and authentications. If the document carries a DFAT apostille, the apostille itself confirms that DFAT verified the notary's signature and seal. You can also check the notary against the records or notaries society in their state or territory. Our guides to verifying a notarised document and verifying an apostille explain the steps.
When a notary retires or stops practising, they stop using their seal, and arrangements in each jurisdiction deal with their register so that past acts can still be checked. Documents they sealed while in practice remain valid notarial acts. If you need to confirm an old notarised document, DFAT's records, the apostille if there is one, and the records or notaries society in the notary's state are the places to start.
Here is an illustration, not a real case. Omar receives a notarised power of attorney back from a notary in Melbourne. The certificate carries an embossed seal that is hard to see in his phone photo, and the foreign lawyer asks whether it has been sealed at all.
Omar explains that the seal is embossed and sends a photo taken at an angle to show the impression. The document also carries a DFAT apostille, which states the seal and the notary's name, and the lawyer is satisfied. For his next document, Omar asks the notary whether they also use an inked stamp, which shows up clearly in scans.
An Australian notary's seal is usually a round embossed or inked seal with the notary's name, the words Notary Public and the place of practice, used on the notarial certificate with the notary's signature and often across the binding. Designs vary, so the seal is verified through DFAT's records, which an apostille confirms. A JP's stamp is not a notarial seal and cannot be apostilled. Our document notarisation services page explains how this works with us.

Usually a round embossed or inked seal showing the notary's name, the words Notary Public and the place of practice, such as a city and state. There is no single national design, so seals vary between notaries.
It can be either, and some notaries use both. Embossed seals are pressed into the paper and are hard to copy; inked stamps show up clearly on scans and photocopies. Both are used with the notary's signature.
On the notarial certificate, next to or over the notary's signature, and often on each page, across the page edges or over the binding, so that every page is identified as part of the bundle.
No. A JP's stamp identifies a volunteer witness for documents used in Australia. It is not a notarial seal, most foreign authorities do not accept it, and DFAT cannot apostille a JP's signature.
Designs vary, so the seal alone proves little. DFAT holds records of Australian notaries' signatures and seals, and an apostille confirms DFAT verified them. You can also check the notary with the records or notaries society in their state.
Contact the notary, who may add a clearer impression or prepare a fresh certificate. Do not trace over or enhance a seal yourself. An apostille, which names the seal, often answers a foreign authority's questions.
Embossed seals are raised impressions with little or no ink, so they often barely appear in scans. A photo taken at an angle shows them better. Some notaries also use an inked stamp for this reason.
No. There is no single national design. Each notary has their own seal, typically with their name, the words Notary Public and their place of practice. What matters is that it matches DFAT's records.
Yes. An apostille records the seal or stamp the document bears, along with the name and capacity of the person who signed. It confirms DFAT verified them.
It depends on the receiving body and how badly the seal or binding is damaged. If the seal is broken or the binding disturbed, contact the notary, as a fresh certificate may be needed.
