The UBO Investigation Handbook:
Finding the Real Owner

Checking a register isn't investigating an ownership structure.

Every AML guide defines a beneficial owner: a natural person who ultimately owns or controls an entity, usually above a 25% threshold. Almost none teach you how to actually find one when the paperwork is designed to obscure them. This guide covers the practical investigative technique, what the registers genuinely show you, where they mislead by default, and how nominee arrangements, layered structures, and trusts are actually unwound in practice.

One thing worth knowing before anything else: the landscape changed in a way a lot of existing AML content hasn't caught up with. On 22 November 2022, the Court of Justice of the European Union struck down the EU's requirement for unrestricted public access to beneficial ownership registers, ruling it violated fundamental privacy rights. Most EU member states closed or restricted public access within days. If your mental model is "just look up the foreign UBO register," that model is largely out of date, most EU registers now require demonstrating a legitimate interest, and some, like Italy's, remain suspended entirely pending further litigation.

Before going further, it's worth being precise about who actually qualifies as a UBO, because "more than 25%" isn't a universal rule the way a lot of training treats it. FATF itself doesn't mandate a specific percentage, its guidance mentions 25% only as an illustrative example of how a threshold could work, not a fixed international standard. The UK and the EU's AMLD6 both apply 25% as the default, though EU member states can lower it to as little as 15% for higher-risk sectors with European Commission approval. Plenty of jurisdictions set the bar meaningfully lower: India applies 10%, South Africa applies as low as 5% for certain financial institutions, Nigeria and Colombia apply 5%, Kenya applies 10%, and Ghana requires disclosure of all shareholders for domestic extractives companies regardless of stake size. The US Corporate Transparency Act uses 25% but adds a separate control prong entirely independent of ownership percentage, someone exercising substantial control over an entity qualifies as a beneficial owner regardless of how small their formal shareholding is. That control dimension matters everywhere, not just in the US, a shareholder sitting just under whatever the local threshold happens to be, deliberately structured at 24.9% rather than 25%, but holding board appointment rights or an effective veto, is still the beneficial owner in substance, and a UBO analysis that stops at the percentage figure on the cap table misses exactly the structuring pattern the threshold was designed to catch.

Four patterns, four visual memory cards

Most beneficial ownership misjudgments trace back to one of these four shapes. Learn to recognise them before the scenarios test them.

Four patterns, the trap that makes each one look routine, the tell that actually gives it away, and the response that fits.

The register is where an investigation starts, not where it ends.

Every pattern in this guide comes back to the same discipline: a register lookup is a data point, not a conclusion. FinCrimeRadar's screening tool lets you check each individual beneficial owner you actually identify against live sanctions and PEP data, free, no account required.
