A notary public gives Know Your Customer (KYC) checks something a scanned passport and a webcam cannot: an independent, legally accountable officer who has seen the person, examined the original document, and put their seal to it.

Banks, fund managers, fintechs, law firms and offshore counterparties all run KYC under anti-money-laundering rules. In Australia that means the AML/CTF Act 2006 and AUSTRAC’s customer identification requirements, now extending to lawyers, accountants and real estate agents under the Tranche 2 reforms. The common friction point is the same everywhere: proving that a document is genuine and that the person presenting it is who they say they are. That is precisely what notaries do.

Verifying identity and certifying documents

The core notarial service for KYC is the certified true copy. The notary inspects the original passport, driver licence or proof of address, compares it with the person in front of them, and certifies that the copy is a true copy of the original sighted. The certificate carries the notary’s signature, seal and registration details, so the receiving institution can verify it independently.

A notary can also take a statutory declaration or affidavit confirming identity, residential address, source of funds or tax residency, and can witness the KYC forms themselves. Because a notary is a court-appointed officer with professional obligations, compliance teams treat notarised evidence as a higher tier of verification than a self-certified upload.

Making KYC documents work overseas

Where a notary becomes indispensable is cross-border onboarding. A foreign bank, exchange, fund administrator or company registry will rarely accept a copy certified by a local JP or pharmacist, but a notarial certificate is recognised internationally.

For countries in the Hague Apostille Convention, the notary’s signature and seal are authenticated by DFAT with an apostille, and the document is then accepted without further steps. For non-Convention countries, the notary prepares the document for DFAT authentication and consular legalisation. The notary can also certify translations and confirm that a document complies with the destination jurisdiction’s formal requirements, saving a rejected application and weeks of delay.

Corporate and beneficial-owner KYC

Companies face a heavier KYC burden than individuals, and this is where notaries add the most value. A notary can:

• Certify company extracts, constitutions, trust deeds and board resolutions as true copies
• Verify the identity of directors, authorised signatories and ultimate beneficial owners
• Attest that a signatory held office and had authority to sign on a given date
• Prepare a notarial certificate of incumbency or good standing for foreign counterparties
• Witness powers of attorney appointing a local representative to complete onboarding

For a trust, SPV or multi-layered group, a single notarial certificate that sets out the ownership chain and certifies the supporting documents can replace a dozen separate requests from a compliance team.

What a notary does not do

A notary verifies documents and identity; the notary does not perform the institution’s risk assessment. Sanctions screening, politically exposed person checks, ongoing monitoring and the decision to onboard remain the reporting entity’s obligation. Notarisation supplies reliable evidence into that process rather than replacing it.

The practical message for anyone opening a foreign account, admitting an offshore investor or onboarding a corporate client is simple. Ask the receiving institution exactly what form of certification it will accept, bring original documents to the notary, and have the apostille or legalisation arranged at the same time. Done properly once, the notarised KYC pack can be reused across multiple institutions and jurisdictions.
