Their affairs may be spread across trusts, companies and investment vehicles, with accountants and advisers co-ordinating much of the administration behind the scenes.The question is less whether a family has a family office than whether its structure remains fit for purpose.According to LGT Wealth Management Australia, the most successful family offices are built around a clearly articulated purpose rather than a desire to emulate larger peers or react to the latest tax changes.“The premise for a family office really should be about how the family’s wealth will be protected, preserved and grown for the benefit of future generations,” says Kaajal Prasad, head of family advisory at LGT Wealth Management Australia, part of LGT Group.That distinction matters because families often establish offices for the wrong reasons. Some are responding to tax reforms while others are drawn to the cachet associated with the concept. But without a shared understanding of what the structure is meant to achieve, complexity can quickly become a burden rather than a benefit.Kaajal Prasad, head of family advisory at LGT Wealth Management Australia, part of LGT Group. One of the most common pitfalls is mistaking formal structures for genuine governance.A family may establish investment committees, appoint well-connected advisers and create sophisticated legal arrangements, yet still lack a common set of principles to guide decision-making. In such cases, what appears robust on paper can provide only the illusion of control.This often occurs when decision-making remains concentrated in the hands of a patriarch or matriarch, with younger generations excluded from meaningful discussions about the purpose of the family’s wealth and how it should be managed.That approach may work while the founding generation remains actively involved. But when control passes to heirs who have not been prepared, disagreements can emerge over investment strategy, spending priorities and long-term objectives.“Poor decision making that leads to wealth erosion and family conflict,” Prasad says.By contrast, strong governance creates a framework in which family members can discuss aspirations, responsibilities and expectations before tensions arise. These conversations can be emotionally charged, but Prasad says they are often surprisingly constructive and can help uncover assumptions that might otherwise lead to conflict.Families are encouraged to address questions such as how long the wealth should last, what values should shape investment decisions and what role each generation should play.The answers are then codified in documents such as family charters and investment policy statements, which act as a “north star” when difficult decisions arise.Generational change is also reshaping investment priorities within family offices globally, particularly as more wealth transitions to younger generations with different attitudes towards risk, impact and long-term stewardship.“The second generation, the risk appetite, or even the perception of risk, is very different,” says Chi-man Kwan, group chief executive officer and co-founder of Raffles Family Office.“The newer generation generally has a stronger sense of responsibility for impact investing and ESG. Biotech, renewable energy and health tech are the things they pay much more attention to.”The shift underscores the importance of governance structures that can adapt as family priorities evolve.Another common mistake is assuming that a family office must be fully staffed from the outset.Founders who built successful businesses are often accustomed to maintaining close control over every major decision. But managing a diversified investment structure requires different skills, ranging from asset allocation and manager selection to tax, reporting and succession planning.For many families, outsourcing key functions can be more effective than attempting to build a large internal team.This approach provides access to specialist expertise while preserving flexibility as the family’s needs evolve. It can also reduce the challenge of recruiting and retaining professionals in highly specialised roles.“The world is increasingly complex from an investment perspective,” says Matthew Tan, head of asset allocation at LGT Wealth Management Australia.Matthew Tan, head of asset allocation at LGT Wealth Management Australia. “It is really a trade-off between how much families want to do internally and how much they trust external providers.”The same principle applies to reporting. As portfolios expand to include private businesses, trusts, property and alternative investments, consolidated reporting becomes increasingly important. Institutional-grade systems can provide a single view across the family’s holdings, reducing blind spots and improving transparency.Above all, the most effective family offices are those that resist unnecessary complexity.“It should be as simple as possible,” Prasad says.To learn more, please visit LGT Wealth Management Australia.
