When Do Businesses Need A Notary Public In Australia?

If you run a small business, there’s a good chance you’ll go months (or even years) without ever needing a notary public. Then suddenly, you’ll be asked for “notarised documents” for something important - like opening an overseas bank account, signing an international distribution agreement, or completing an export deal - and it can feel like you’ve hit a paperwork wall.

Notarisation is one of those legal steps that often only appears when you’re dealing with an international party (or an Australian organisation following international compliance rules). The good news is: once you understand what a notary public does, it becomes much easier to work out whether you actually need one, what to prepare, and how to avoid delays.

Below, we break down what a notary public is in Australia, why notarisation matters for small businesses, and the common scenarios where it’s required.

What Is A Notary Public In Australia?

If you’re asking “what is a notary public?”, the simplest explanation is this: a notary public (also called a public notary) is a specially appointed lawyer who can verify and certify documents for use - most commonly - overseas.

In Australia, a notary public is usually an experienced solicitor who has been appointed by the relevant state or territory authority (often through a Supreme Court process). Notaries are trusted internationally because they are authorised to:

• verify a person’s identity
• witness signatures
• certify true copies of documents
• prepare and certify certain notarial certificates
• administer oaths and affirmations (depending on the circumstances)

From a small business perspective, notarisation is often required because an overseas organisation (a bank, government agency, investor, supplier, distributor or customer) wants extra confidence that:

• the person signing is who they say they are, and
• the document is genuine (or a true copy), and
• the signature was applied properly and voluntarily.

Put another way: notarisation is a way of making your document “travel well” internationally - but whether it’s needed (and what form it must take) can depend on the destination country and the organisation requesting it.

Why Notarisation Is Common In International Business

Australian documents don’t automatically carry legal weight overseas. A notary public adds a recognised layer of formal verification, which is why notarisation often pops up when you’re:

• dealing with overseas compliance checks (KYC/AML requirements)
• setting up foreign entities or bank accounts
• signing contracts governed by a foreign law
• providing corporate documents to overseas counterparties

Notary Public vs Justice Of The Peace: What’s The Difference?

A really common point of confusion is whether a notary public is the same as a Justice of the Peace (JP). They’re not the same - and choosing the wrong one can cause frustrating delays (especially when you’re up against a deal deadline).

Justice Of The Peace (JP)

A JP can usually witness signatures and certify copies for many Australian purposes. For example, you might use a JP for local statutory declarations or identity checks that are being used within Australia.

However, many overseas organisations won’t accept a JP certification because they specifically require notarisation by a notary public (and sometimes additional steps like an apostille or consular legalisation).

Notary Public

A notary public is typically used when documents must be accepted outside Australia or by an organisation that needs a higher level of verification. Notaries also often provide a notarial certificate and use their seal, which is an internationally recognised indicator of authenticity.

If the request says “notarised” (or mentions an apostille), it’s a strong sign you need a notary public - not just a JP.

When Do Small Businesses Need A Notary Public?

Most small businesses need a notary public for one main reason: international transactions.

Even if your business is based entirely in Australia, you may still be asked for notarised documents when an overseas party’s internal rules require it (for example, a foreign bank’s onboarding requirements).

Common Business Scenarios Where Notarisation Comes Up

Here are some of the most common times small businesses are asked to notarise documents:

• Opening an overseas bank account or payment facility (including fintech or merchant account providers that use offshore banks).
• Registering a subsidiary or branch overseas, or appointing someone to act for the company in another country.
• Raising funds from overseas (e.g. foreign investors who want certified corporate documents and identity verification).
• Signing international distribution or supply agreements, especially where the counterparty needs formal proof of signing authority.
• Exporting goods where overseas authorities require certified supporting paperwork (depending on the country, the product, and the specific documents requested).
• Overseas property or leasing transactions for business expansion.
• Overseas IP and brand matters (for example, signing documents for foreign trade mark filings in some jurisdictions).

Do You Always Need A Notary For Overseas Documents?

Not always. Some overseas counterparties will accept:

• a plain signed document
• a witnessed document (by a JP or lawyer)
• a certified copy (not necessarily notarised)

But if you’re specifically asked for “notarised” documents, it’s best to treat that as a firm requirement unless the requesting party confirms otherwise in writing.

Also, some countries require an extra step after notarisation (like an apostille). If you’re unsure, it’s worth clarifying the exact requirement early - before you book appointments and sign anything.

What Documents Might Need Notarisation For A Business?

Notarisation can apply to lots of business documents, but the most common ones tend to fall into a few categories.

1. Company And Corporate Documents

Overseas banks, investors and counterparties often ask for certified company records to confirm your business exists and is properly authorised to do what it’s doing.

Examples include:

• company registration extracts and related records
• board resolutions approving a transaction
• shareholder resolutions (depending on what’s being done)
• a copy of your constitution (if requested)
• evidence of who directors and shareholders are

If you’re still setting up your structure (or expanding into a company structure), it can help to have your foundations right from day one - including a proper Company Set Up and a tailored Company Constitution.

2. Proof Of Signing Authority

A big reason businesses get asked for notarisation is to prove that the person signing is authorised to sign on behalf of the business.

For example, you might need notarisation where:

• one director is signing for the company in a high-value deal
• a manager is signing under delegated authority
• an overseas party wants confirmation the signatory can bind the business legally

Depending on the context, you may also be asked for a formal authorisation document - for instance, an Authority to Act Form - so the counterparty can rely on it with confidence.

3. Identity Documents (For KYC / AML Checks)

It’s very common to be asked for notarised copies of identity documents where an overseas bank or platform is running strict onboarding checks. This can include:

• passports
• driver licences
• proof of address documents

These are often required for directors, shareholders, or beneficial owners.

4. Contracts, Deeds And Commercial Agreements

Some international transactions require notarised execution, particularly where the agreement will be relied upon in a foreign jurisdiction or needs extra formality.

While notarisation doesn’t automatically make a contract “better”, it can be part of meeting the other party’s legal or compliance requirements - and it can reduce disputes about whether a signature is genuine.

Before you sign something internationally (especially if it’s governed by foreign law), it’s worth getting it reviewed so the legal and commercial risk is clear. In many cases, a Contract Review can help you avoid signing terms that are unworkable for your business.

5. Business Ownership Or Share Documents

If you have co-founders, investors, or you’re changing your ownership structure, you may deal with documents that an overseas party needs to see in notarised form.

It’s also common for overseas investors to ask how ownership decisions are made and what happens if founders disagree. This is where a tailored Shareholders Agreement can be a practical tool (and it often helps with investor due diligence even before notarisation becomes an issue).

6. Website And Privacy Documents (For International Expansion)

If you’re expanding online into other markets, you may be asked to provide compliance documents as part of the broader onboarding or due diligence process. While these documents aren’t usually notarised themselves, they can come up alongside notarisation requirements (for example, where you’re opening overseas payment accounts or entering foreign platform agreements).

At a minimum, it’s worth making sure your Privacy Policy and Website Terms and Conditions reflect how you actually collect and use customer data.

How Does The Notarisation Process Work In Practice?

If you’ve never arranged notarisation before, it can feel intimidating - but the process is usually straightforward once you have the right documents ready.

Step 1: Confirm Exactly What The Overseas Party Requires

Before booking a notary appointment, clarify:

• Which documents need to be notarised (originals, copies, or both)
• Whether the overseas party needs an apostille or consular legalisation after notarisation
• Whether they require a specific form of notarial certificate wording
• Whether signing must happen in front of the notary (often yes)

This small step can save you a lot of time and rework.

Step 2: Prepare Your Documents And Supporting Information

Notaries generally need to verify identity and understand what they are certifying. You may be asked to bring:

• government-issued photo ID
• the document(s) to be notarised (unsigned if it must be witnessed)
• any instructions from the requesting party (email is often fine)
• company information if signing on behalf of the company (e.g. ACN details, evidence of directorship, or a board resolution)

If you’re signing for a company, make sure the signing method matches what the counterparty expects and what your internal documents allow (for example, signing under a constitution or pursuant to a board resolution).

Step 3: The Notary Verifies, Witnesses And Certifies

At the appointment, the notary may:

• verify your identity
• confirm your capacity/authority (e.g. director, authorised representative)
• witness you sign the document (if required)
• certify copies as true copies (if required)
• attach a notarial certificate and apply the notarial seal

This is also where a notary might flag an issue - for example, if the document appears incomplete, the name on the ID doesn’t match, or the signing party can’t demonstrate authority.

Step 4: Next Steps (Apostille Or Consular Legalisation)

In some cases, notarisation is not the final step. Depending on the destination country, you may also need:

• An apostille: a form of authentication used between countries that are part of the Hague Apostille Convention. In Australia, apostilles are issued by the Department of Foreign Affairs and Trade (DFAT) (including through Australian Passport Offices).
• Consular legalisation: a further authentication process through the relevant foreign consulate or embassy (common for countries that are not part of the Hague Apostille Convention, and for some document types).

Your overseas counterparty should be able to tell you what they require, but if they can’t, it’s usually best to ask for the country-specific instructions in writing.

How Much Does A Notary Public Cost?

Notary fees vary depending on:

• how many documents you need notarised
• whether the notary needs to draft a notarial certificate
• how urgent the request is

Because notarisation is a specialised service, it’s generally more expensive than getting a JP to witness a signature. If cost is a concern, consider whether the overseas party genuinely requires notarisation or whether a standard certification/witnessing will be accepted.

Common Mistakes That Slow Things Down

When a small business is under pressure to move quickly, notarisation issues can cause avoidable delays. Some common pitfalls include:

• signing the document before the appointment (when it needed to be signed in front of the notary)
• bringing the wrong version of the document (for example, an unsigned draft)
• name mismatches between the document and your ID (including middle names)
• not having proof of authority to sign for the company
• finding out too late that an apostille is also required

If you’re handling a bigger transaction with moving parts (contracting, authority documents, corporate approvals, and overseas compliance), it can help to get your documents prepared in a coordinated way, rather than treating notarisation as a last-minute add-on.

Key Takeaways

• What is a notary public? A notary public is a specially appointed lawyer who verifies and certifies documents, most commonly for use overseas.
• Small businesses usually need notarisation when dealing with international banks, investors, government bodies, or overseas counterparties - but the exact requirements can vary depending on the country and organisation.
• A notary public is different from a JP - if the request says “notarised”, a JP certification often won’t be accepted.
• Common documents that may need notarisation include identity documents, corporate documents, proof of authority, and certain international agreements.
• Always confirm whether the destination country requires additional authentication after notarisation (such as an apostille or consular legalisation). In Australia, apostilles are issued by DFAT.
• Good preparation (correct documents, correct signing method, and clear authority) helps you avoid delays and keeps your deal moving.
