Independent Legal Advice and Loan Enforcement

Loan agreements and mortgages are among the most significant legal documents individuals and business owners will sign. They carry long-term financial consequences and, if default occurs, expose borrowers to possession proceedings and substantial cost liabilities.

The recent Supreme Court of Victoria decision in ANZ Bank v Hau Thi Nguyen [2026] VSC 31 provides a detailed examination of what happens when a borrower later alleges that loan documents were forged and that the lender acted unconscionably. While the case was decided in Victoria, the principles applied are equally relevant in New South Wales, particularly in mortgage enforcement proceedings.

The decision is also a timely reminder of the protective function of independent legal advice before signing finance, refinance or guarantee documentation.

The Background to the Dispute

In 2016, ANZ advanced $298,000 to Ms Nguyen for the purchase of a commercial property. The loan was secured by a registered mortgage over the property. It was not disputed that the funds were advanced or that repayments were made for a period before default occurred.

The dispute arose years later, after arrears accumulated and enforcement proceedings were commenced. Ms Nguyen alleged:

• She did not sign the Letter of Offer or Mortgage;

• Her signature had been forged;

• The loan documents were backdated;

• The bank had engaged in unconscionable conduct.

The Court was therefore required to determine whether the borrower had in fact executed the documents and whether the bank was entitled to enforce the loan, including interest and charges.

The Forgery Allegation and Expert Evidence

Central to the borrower’s defence was the assertion that the signature on the Letter of Offer and Mortgage was not hers.

Both parties relied on forensic handwriting experts. Initially, the borrower’s expert expressed a view that the signatures were the product of simulation or forgery. However, after reviewing a broader range of specimen signatures, that expert revised his opinion and concluded that he could not form a concluded view as to authorship. The bank’s expert similarly described the examination as inconclusive.

As Matthews J observed, neither expert ultimately expressed a concluded opinion that the signatures were forged. In the absence of persuasive expert evidence, the allegation of forgery was not made out.

Importantly, the Court did not approach the issue solely through the lens of handwriting comparison. Her Honour assessed the surrounding circumstances, including the advance of funds, the making of repayments, the internal bank records and the credibility of witnesses.

This reflects a broader evidentiary principle: allegations of forgery are serious and must be supported by cogent and persuasive evidence. Mere assertion, even when strongly held, is insufficient.

The Date Discrepancy

A further complication concerned an inconsistency between the typed date on the Letter of Offer (19 July 2016) and a handwritten date of 20 June 2016 appearing beneath the borrower’s signature.

Earlier in the proceedings, this discrepancy was sufficient to prevent summary judgment for interest and fees. At trial, however, the relevant ANZ employee gave evidence that the handwritten reference to “June” was an error and should have been “July”.

Matthews J carefully considered this issue. Her Honour was not persuaded that the discrepancy established fabrication or fraud. Rather, it was consistent with an administrative mistake.

The Court’s reasoning underscores an important practical reality: clerical inconsistencies may complicate proceedings, but they do not automatically invalidate otherwise enforceable agreements. The broader factual matrix remains critical.

Unconscionable Conduct

Ms Nguyen also alleged that ANZ engaged in unconscionable conduct.

In addressing this issue, Matthews J applied orthodox principles. Unconscionable conduct requires more than a disadvantageous transaction. It requires exploitation of a special disadvantage.

Her Honour noted the importance of procedural fairness given that the defendant was self-represented and spoke limited English. The Court took deliberate steps to ensure that the defendant understood the process and was able to present her case.

However, on the evidence, the Court was not satisfied that ANZ had exploited any special disadvantage. The loan funds were advanced, the mortgage was registered, and the defendant had made repayments for a period of time.

Her Honour observed that while the defendant “would have benefitted from independent legal advice and assistance”, she had been given every opportunity to obtain such advice but had refused. That observation is particularly significant.

It highlights a recurring feature in finance disputes: borrowers frequently assert misunderstanding or lack of awareness after default has occurred. Courts will examine whether the borrower had the opportunity to seek advice and whether there was evidence of pressure or exploitation.

Absent clear evidence of unconscientious dealing, courts will enforce the bargain made.

The Court’s Findings

Having considered the lay evidence, expert evidence and documentary material, Matthews J concluded that:

• The defendant signed the Letter of Offer and Mortgage;

• The loan agreement was proven;

• The mortgage was enforceable; and

• ANZ was entitled to recover the outstanding interest and charges and to pursue possession .

The decision demonstrates that where funds have been advanced, security registered, and repayments made in accordance with the agreement, courts will be slow to invalidate the transaction without compelling evidence.

The Relevance for New South Wales Borrowers

Although this case arose in Victoria, the reasoning aligns with principles applied in New South Wales.

Under the Real Property Act 1900 (NSW), a registered mortgage confers significant rights, including a statutory power of sale. Once default occurs and proper notices are served, lenders may accelerate the debt and seek possession.

Similarly, allegations of forgery in NSW require clear and persuasive proof. Courts will look at the totality of evidence, including conduct after execution.

Claims of unconscionable conduct are assessed in accordance with equitable principles and statutory provisions such as the Australian Consumer Law and, in appropriate cases, the Contracts Review Act 1980 (NSW). However, mere regret or misunderstanding does not suffice.

Why Independent Legal Advice Is So Important

One of the more striking aspects of the judgment is the Court’s acknowledgment that the defendant would have benefitted from independent legal advice.

Independent legal advice serves several critical functions.

First, it ensures that the borrower understands the legal effect of the documents. Letters of Offer frequently contain acceleration clauses, default interest provisions, indemnities for enforcement costs and administrative charges. These provisions are enforceable if properly incorporated.

Secondly, advice clarifies the risk associated with granting a mortgage. A mortgage is not merely a formality; it is a proprietary security interest. Upon default, the secured property is at risk.

Thirdly, independent advice reduces the scope for later disputes. Where a solicitor has explained the documents and certified that advice was given, it becomes significantly more difficult to argue that the borrower did not understand the transaction.  This is particularly important in refinance and guarantee situations. Guarantors, especially spouses or family members, may be exposed to liability without direct benefit. Courts in both NSW and Victoria have long recognised the importance of ensuring that guarantors receive independent advice to avoid later challenges.

Finally, independent advice provides an opportunity to identify inconsistencies before execution. In Nguyen, the date discrepancy became a focal point of litigation. A careful review at the time of signing may have clarified or corrected that issue.

A Broader Lesson

The broader lesson from ANZ Bank v Nguyen is not simply that banks can enforce their securities. It is that courts will undertake a detailed evidentiary analysis and will enforce properly executed finance documents where the evidence supports their validity.

Matthews J approached the matter methodically, assessing witness credibility, documentary records and expert opinion. Her Honour reiterated established principles about evaluating lay evidence and the fallibility of memory, noting that contemporaneous documents are often more reliable than recollection.

In that context, borrowers who sign complex finance documents without legal advice assume considerable risk. Years later, when disputes arise, recollection may be uncertain, documents may have been digitised, and positions hardened.

Independent legal advice at the outset is not merely a procedural formality. It is a substantive safeguard.

ANZ Bank v Nguyen [2026] VSC 31 reinforces that allegations of forgery and unconscionable conduct must be supported by persuasive evidence. Courts will not lightly set aside loan agreements and registered mortgages where funds were advanced and repayments made.

For borrowers and guarantors in New South Wales, the case serves as a clear reminder: finance, refinance and guarantee documents should never be signed without careful review and independent legal advice. The cost of advice at the outset is modest when compared with the cost and uncertainty of mortgage enforcement litigation.
