Registers record legal ownership. Beneficial ownership is the question of who actually benefits and who actually decides. The two coincide in most companies and diverge in every structure built to conceal.
FATF and the Egmont Group examined 106 case studies of concealed ownership and found the same small set of devices recurring: nominee shareholders and directors, corporate directors, layered structures across multiple jurisdictions, bearer instruments, trusts and foundations, and the routine use of a professional intermediary who knows the client’s identity but does not disclose it. Almost every corporate technique documented on this site is a variation on one of those.
