Abstract Multi-jurisdictional wealth architectures are routinely optimised at the vehicle level but rarely analysed for structural vulnerabilities at the network level. This article applies graph theory to patrimonial structures, computing triangle counts for each relationship to identify structurally fragile links—those whose disruption isolates portions of the patrimony with no alternative path. An illustrative 19-entity structure spanning four jurisdictions reveals that 52% of relationships are structurally irreplaceable, with direct implications for fiduciary governance, succession planning, and foundation administration.
