Pre-Settlement Flash Audit for Bunbury Conveyancers: Detect Deepfake-Voice Wire Instructions Before Settlement

The phone rings the morning of settlement. It’s your client — same voice, same cadence, slightly stressed — asking you to redirect the trust transfer to a “new account my bank set up overnight.” You’ve spoken to this person a dozen times. The voice is right. Everything else feels almost right. The Pre-Settlement Flash Audit is a one-shot diagnostic that checks a specific settlement file for the structural indicators most often present when a deepfake-voice instruction is used to redirect settlement funds.

Why it matters now

Under the Electronic Conveyancing National Law, Subscribers (including conveyancers and settlement agents lodging through PEXA) must comply with the Participation Rules determined by the Registrar in each jurisdiction. The current Model Participation Rules (Version 7, published January 2024 by the Australian Registrars’ National Electronic Conveyancing Council) require Subscribers to maintain security controls over their digital signing and to verify their clients’ identity and authority to deal — obligations that long predate generative-AI voice cloning but apply directly to it. The Australian Cyber Security Centre publishes general guidance on social engineering and impersonation threats at https://www.cyber.gov.au/, and ACCC Scamwatch (https://www.scamwatch.gov.au/) tracks payment-redirection scams as one of the highest-loss categories affecting businesses. Voice-based instruction is not, by itself, sufficient evidence of authority — and synthetic voice now removes the last informal trust signal a settlement agent could previously rely on.

The 5-minute view

• ARNECC’s Model Participation Rules Version 7 (January 2024) is the current model framework Registrars use as the basis for jurisdictional Participation Rules under the Electronic Conveyancing National Law
• Subscribers are required under the Participation Rules to take reasonable steps to verify the identity of the person they take instructions from and that person’s authority to deal
• A telephone call alone — even one that “sounds like” the client — is not a Verification of Identity standard under the Model Participation Rules
• Generative-AI voice cloning can reproduce a short voice sample with enough fidelity to deceive a familiar listener; the structural defence is the verification protocol, not the listener’s ear
• Common indicators on a deepfake-voice instruction include: instruction arriving outside the client’s normal contact pattern, a same-day account change, refusal or inability to complete a callback to the previously verified number, and emotional pressure to act before settlement
• Out-of-band verification — calling the client back on a number obtained at the original VOI step, not a number provided in the suspect call — is the recognised control
• A pre-settlement flash audit reviews the specific file’s instruction chain, verification record, and the structural pattern of any voice or phone-based change request

What DRMO does about it

The Pre-Settlement Flash Audit is a single-transaction diagnostic delivered against one settlement file. You submit the file reference, the verification record on file (VOI documents, client authorisation, originally verified contact number), and the sequence of instructions received — including any phone or voice instruction received in the final fortnight before settlement. We run a fixed-scope review against the obligations expressed in the Model Participation Rules and against published guidance on impersonation threats. The audit identifies whether the file’s instruction chain is consistent with the verification record, whether any account-detail change is supported by a re-verification step, and what the recommended verification action is before funds are released. This is the same diagnostic that runs as a checkpoint within the broader Pre-Settlement Shield engagement, productised here for single-file use without a discovery call.

The deliverable

• 15-page PDF audit report scoped to one settlement file
• Executive summary with a Red / Amber / Green status and the recommended next action before funds release
• Per-indicator review of the instruction chain, with the underlying evidence cited from the file you submit
• Verification protocol checklist (callback to verified number, written confirmation, in-person sign-off where required) aligned to the Model Participation Rules obligations
• Delivered via email within 1 business day of file submission and payment
