When Wealth Becomes a Vulnerability: The Hidden Crisis of Elder Financial Abuse

There is a cruel irony at the heart of elder financial abuse: the same formidable individuals who built empires and wealth through determination, guile and an unerring command of their affairs are often, in their later years, the most vulnerable targets of those seeking to exploit them. The very traits that drove their success; loyalty to trusted relationships, confidence in their own judgment, a lifetime of making decisions without question; can be turned against them with devastating precision.

This is not just an abstract issue. Elder financial abuse occurs at a troubling intersection of wealth, cognitive decline and the human need for connection.

In Australia, one in six older Australians now reports experiencing some form of elder abuse, with financial abuse consistently among the most prevalent forms¹. However, when the topic involves high-net-worth individuals, advisers, lawyers and families, too often look away, believing that wealth offers protection. It does not. In many cases, it is the lure.

In France, the concept has a name: abus de faiblesse; abuse of weakness. It gained international notoriety through the case of Liliène Bettencourt, the late L’Oréal heiress and one of the world’s wealthiest women. Her family claimed that artist François-Marie Banier had accumulated over $2 billion in gifts and benefits through sustained influence over a woman of diminished capacity. More recently, the case of Nicolas Puech, a fifth-generation Hermès heir with an estimated $22 billion stake in the company, has raised similarly grave questions about the exploitation of the elderly wealthy. These are not isolated cases; they serve as warnings.

For wealthy Australians, elder financial abuse tends to manifest along three distinct fault lines, each seemingly normal in appearance.

Underlying all three risk vectors is the question of cognitive decline. Undiagnosed Alzheimer’s disease and other dementias do not come with a formal announcement. They develop over years, subtly at first, showing as occasional lapses that the individual might rationalise or conceal. The person who insists they are managing their affairs may be doing so from a position of significantly diminished capacity. The adviser who fails to notice or chooses not to is failing in their duty of care.

This is where the issue shifts from a personal matter to a professional one. Advisers who have been trusted custodians of a client’s financial affairs for decades are uniquely positioned to observe the early indicators of cognitive change. They are also, at times, uniquely motivated to look away out of concern for damaging a valued relationship, fearing they might be seen as overstepping, or worrying about losing the engagement entirely if a challenging observation provokes a reaction. This is a failure of professional courage, and it has consequences.

Against a concerted and patient programme of exploitation, no single safeguard is enough. What is required is a properly integrated, regularly tested architecture of protection. The core elements are well established, though they are too seldom implemented with the rigour the situation demands.

Structural independence within governance frameworks is paramount.

Trusts should have independent appointors or guardians; individuals or institutions with no stake in the outcome and whose explicit approval is required for material transactions. This is not bureaucratic friction; it is a deliberate counterweight against the day-to-day manager of trust assets acting, whether under pressure or of their own volition, outside the intended parameters of the structure.

Professional custody and independent administration of assets, combined with regular, independently verified reconciliations, creates a paper trail that both deters and detects impropriety. The custodian who understands the consents required under the trust deed and who is prepared to enforce them is an invaluable line of defence.

Binding Financial Agreements, Wills, Enduring and Medical Powers of Attorney need to be conceived and documented as parts of an integrated system, not in isolation. That system must undergo stress testing. A well-designed document that has never been reviewed under a realistic stress scenario may fail at precisely the moment it is most needed. Frameworks should be revisited whenever there is a material change in circumstances, such as a new relationship, a death in the family, a health event, or a change in the composition of the advisory team.

Regular oversight meetings bringing together legal, tax, investment and governance advisers serve both practical and protective functions. They maintain a living record of the client’s decision-making capacity and intentions, and they create multiple touchpoints through which early warning signs might be observed and acted upon.

Cognitive health should be approached with the same proactive rigour as physical health. A wealthy individual who undergoes annual cardiac screening but has never had a formal assessment of executive function is not managing their risks comprehensively. Normalising, destigmatising and planning periodic cognitive reviews well in advance allow the protective frameworks to be activated while the individual still has the capacity to instruct their implementation

The adviser who has spent years understanding a client’s values, family dynamics and financial intentions bears a responsibility that extends beyond technical competence.

When the signals of cognitive decline appear - and they will - clients should not wait for a formal diagnosis, or rely on a family member who may be the very party presenting a risk. The obligation is to use the frameworks designed together to protect the client, and to be prepared to name, clearly and on the record, what is being observed.

This is uncomfortable work. It may cost the relationship. In a small number of cases, it may cost the engagement. The alternative, however, is standing by while a client’s carefully built wealth is redirected by those who have identified and are exploiting a vulnerability, which is neither a defensible position, professionally or morally.

The French courts, in the Bettencourt matter, ultimately found that exploitation had occurred over many years before any intervention. The real tragedy was not the sums involved, extraordinary as they were, but the years during which those closest to her, and those paid to serve her interests, failed to act. Australia’s wealthy elderly deserve better. Their advisers should uphold that standard.
