Ultimate Beneficial Ownership (UBO) Decoupling Protocols require corporate compliance teams to unpack multi-layered corporate structures across diverse offshore jurisdictions to trace control back to an active natural person holding a ≥ 10% to 25% ownership stake or exercising direct dominant corporate control. Investigations require mapping through sequential shell layers (e.g., Target operating asset → BVI Shell Company → Cook Islands Blind Trust → Nominee Proxy Trustee), systematically using local corporate filings and asset declarations to break hidden entity structures before authorizing trade credit limits.
