When a Client’s Loss Points to Professional Negligence Disputes 6th August 2026 Author Jessica Latimer For accountants, financial advisers and other trusted referrers, one of the hardest conversations with a client is the moment they realise that a financial loss may not simply be the result of market conditions, commercial risk or bad luck. Sometimes a loss has been caused by a professional who failed to exercise reasonable care, acted outside their authority, gave unsuitable advice, missed a critical deadline, or failed to protect the client’s position. We are seeing an increasing number of claims involving professionals, including against lawyers, financial advisers and stockbrokers. These matters often involve substantial capital loss, but the true loss can be much broader. A client may also have lost the opportunity to deploy that money elsewhere, protect their financial position, pursue another investment, reduce debt, fund retirement, or preserve working capital for a business. Professional negligence is more than a disappointing outcome Not every poor outcome gives rise to a claim. Investments can fall, litigation can be uncertain, and commercial decisions can carry risk. The critical question is whether the professional met the standard expected of a reasonably competent practitioner and whether the failure caused loss. Claims may arise where, for example, a financial adviser recommended an unsuitable strategy, failed to explain material risks, failed to consider the client’s objectives or risk tolerance, or placed the client into a product that was not appropriate for their circumstances. Claims against lawyers may arise where a limitation period was missed, advice on a loan fell short of the required standard or a client was not warned about a material risk. Claims against stockbrokers may arise where unauthorised trades were made, shares were sold without authority, a client’s mandate was exceeded, or an employee misappropriated client funds or assets. Insurance can make recovery realistic A common reason clients do not pursue a claim is the assumption that it will be too difficult, too expensive, or that the professional will not have the resources to meet a judgment or settlement. In most professional negligence matters, there is likely to be professional indemnity insurance or other responsive cover. Where insurance is available, it can significantly change the commercial dynamics of a claim. Insurance does not guarantee recovery, and every claim must be assessed on its facts. But it can provide a practical pathway to resolution, particularly where the claim is well-prepared, causation is addressed carefully, and the loss is properly quantified. In the right case, early investigation and strategic engagement with an insurer can deliver outcomes that restore the client’s financial position or materially reduce the damage suffered. Consequential loss: the loss is not always limited to the money taken or lost One of the most important issues in these claims is consequential loss. The immediate loss may be obvious: the value of shares sold without authority, money paid into an unsuitable investment, legal rights lost because of negligent advice, or capital eroded by an inappropriate strategy. But that is not necessarily the full extent of the damage. Clients may also have lost opportunities that had real financial value. They may have been unable to purchase another asset, invest in a different opportunity, reduce interest-bearing debt, contribute to superannuation, fund business expansion, meet tax obligations, or maintain liquidity during a difficult period. Where those losses can be linked to the professional’s conduct, they should be considered as part of the claim. Loss of opportunity can be particularly important. The law recognises that the loss of a real and valuable chance may itself be compensable. A client does not always need to show that an alternative outcome was guaranteed. In appropriate cases, the question is whether the client was deprived of a genuine opportunity with measurable value. Warning signs for accountants and financial advisers Referrers are often the first to identify that something is not right. A client may present with unexplained losses, missing shareholdings, unusual transaction histories, advice that does not match their risk profile, documents they did not understand, or a missed opportunity that has caused broader financial harm. Potential red flags include: investment advice that appears inconsistent with the client’s objectives, age, or risk appetite; transactions the client says they did not authorise or understand; shares or funds moved, sold or transferred without clear instructions; advice that was not properly documented or explained; missed legal deadlines, limitation periods or settlement opportunities; or a sudden deterioration in a client’s financial position following reliance on professional advice What clients should do early Timing matters. Professional negligence claims can be affected by limitation periods, document retention issues, insurance notification requirements and the availability of evidence. Clients should obtain advice early, preserve all relevant records, and avoid assuming that a loss is unrecoverable simply because the professional denies responsibility or the underlying transaction appears complex. Key documents will often include the professional’s file, engagement letters, written advice, file notes, emails, transaction records, account statements, instructions, portfolio histories, insurance correspondence and any complaints or internal reviews. A careful chronology is also valuable, particularly where the claim involves consequential loss or a lost opportunity. How we can help Our Disputes team acts for clients in professional liability matters. We assess both liability and the claimable losses and can often achieve a commercial outcome without litigation. We have recently achieved successful outcomes for our clients against former solicitors who breached their obligations and against a former accountant for failing to consider tax consequences of a course of action, where the loss was identified by the client’s new accountant. If you have a client who has suffered financial loss and there is a concern that professional advice, misconduct or unauthorised conduct may have contributed to that loss, it is worth having the position reviewed. The loss may well be recoverable, and it may be broader than the amount first apparent. Contact us Please contact us for more detailed and tailored help.
