Private Client Tax Committee

The Committee focuses on inheritance rights, will making, lifetime giving, trusts, creditor claims, regulatory compliance, charities, taxation, property rights, and conflict of law rules, considering both domestic and cross-border implications. Members benefit from enhanced knowledge, expertise in cross-border issues, global networking, and access to leading experts. The committee addresses international planning, comparative law, and topics like individual tax in cross-border contexts, trusts for planning, international successions, and asset protection. It frequently holds joint sessions with the Taxes committee and other IBA sections, offering a valuable resource for practitioners in private client work.

Murphy’s law in estate planning: things will and have gone wrong

This panel session explored real-life scenarios where detailed planning of succession and wealth-holding strategies have not gone to plan. Cross-border examples were used to highlight situations where such plans have shifted due to the interplay between different legal systems, family structures and human error. Rather than adopting a pessimistic tone, the session positioned Murphy’s law, the adage that ‘anything that can go wrong, will go wrong’, as a practical discipline that is relevant to estate planners advising global families with cross-border assets. Indeed, during cross-border planning, ‘anything that can go wrong, will go wrong’.
