Significant beneficial owner rules require declaration, company filings, notices and permit tribunal orders and penalties. Individuals meeting the prescribed beneficial-interest threshold or exercising significant influence are significant beneficial owners and must declare particulars to the company; companies must maintain a register, allow prescribed inspection, and file returns with the Registrar. Companies may serve notices on persons believed to be significant beneficial owners or knowledgeable of them, requiring responses within thirty days; failure or unsatisfactory replies permits the company to apply to the Tribunal for restrictions on transfers and suspension of rights, and the Tribunal may order or later relax such measures. Penalties apply for non-declaration, register or filing defaults, denial of inspection, and for wilful falsehoods.
