As global families increasingly hold assets, structures and family members across multiple jurisdictions, succession planning is becoming more vulnerable to conflicts between civil law and common law systems. This session will explore the practical challenges that arise when trusts, foundations, matrimonial regimes and forced-heirship rules intersect internationally. We will focus on pre-nuptial and succession agreements, the cross-border recognition of trusts and foundations, and the tensions between forced heirship and common law planning structures. Considering different jurisdictions, we will share practical approaches to making international estate plans more “dispute-proof,” including governance mechanisms, trustee selection, protectors and no-contest clauses designed to reduce future litigation risk.
