In a world where family offices play a central role in managing ultra-high-net-worth wealth, the complexity of assets demands high-level legal and tax expertise to navigate investments, estate planning, and family governance.
Your strategic partner for secure and optimized wealth management.
Family offices are critical in managing the wealth of ultra-high-net-worth families, whose assets often exceed $100 million. These families, holding complex assets such as diversified investment portfolios, family businesses, and real estate holdings, face unique challenges in tax, legal, and estate management. Twin Lisbet positions itself as your strategic partner to successfully navigate these challenges and ensure the longevity of your wealth.
Managing wealth of this magnitude requires an integrated approach, combining business law, international taxation, regulatory compliance, and estate planning. In 2024, the uneven recovery of private markets, evolving legislation, and the lingering impact of the pandemic on family businesses have increased the complexity of these issues. In this context, our experts, Audrey Ann Dumont, CPA, a seasoned tax specialist, and Me Amal Sebti, LL.B., a lawyer in tax and business law, offer tailored solutions to help influential families in Canada and the United States protect and grow their wealth optimally.
The chart below illustrates the distribution of global infrastructure transactions by sector from 2015 to 2024, expressed as a percentage of the total transactionEAD transaction value. This chart highlights a key trend for family offices: the diversification of investments into resilient and high-potential sectors. The transportation sector, which dominated in 2015 at 46%, dropped to 22% in 2023 before rising to 29% in 2024. Conversely, the telecommunications sector saw significant growth, rising from 5% to 16% over the same period. This shift, coupled with a notable increase in social sector investments (from 9% to 16%) and a slight decline in energy (from 15% to 13%), underscores the growing interest of family offices in sectors with strong long-term growth and sustainability potential. For wealthy families, these trends emphasize the importance of optimizing investment allocation while addressing complex tax and legal requirements.
