UBO

Definition

An Ultimate Beneficial Owner (UBO) is the natural person(s) who ultimately owns or controls a legal entity, trust, or other structure, regardless of how ownership is layered through companies, nominees, or other intermediaries.

A UBO may exercise control through direct or indirect shareholdings, voting rights, the right to appoint/remove management, or other means.

Why it matters

Identifying the UBO is a core requirement of anti-money laundering (AML) and counter-terrorist financing (CTF) regulations worldwide.

In the UK, UBO information must be disclosed on the People with Significant Control (PSC) register for companies and on the Trust Registration Service (TRS) for relevant trusts. This transparency helps prevent the misuse of legal entities for hiding assets or laundering money.

How UBO identification works in the UK

1. Ownership analysis – Trace direct and indirect shareholdings or control rights through corporate structures.
2. Threshold test – A UBO is generally anyone with more than 25% ownership or voting rights, or who otherwise exerts significant control.
3. Verification – Confirm identity using reliable, independent sources.
4. Documentation – Keep clear records of the ownership/control structure.
5. Ongoing monitoring – Update UBO records when ownership changes.

Examples and use cases

• Company formation – Declaring UBOs to Companies House via the PSC register.
• KYC/KYB onboarding – Identifying UBOs for all corporate and trust clients.
• High-risk transactions – Performing enhanced due diligence (EDD) on UBOs in sensitive jurisdictions.
• AML compliance audits – Ensuring complete, up-to-date UBO records.

Mini-FAQ

Q: What is the difference between a legal owner and a UBO?
A: A legal owner is the named holder of shares or assets; a UBO is the individual who truly benefits from or controls them. They may be the same person, or the UBO may be behind multiple layers of ownership.

Q: Is UBO disclosure public in the UK?
A: For companies, yes - via the PSC register at Companies House. For trusts, information is held in the TRS and is not publicly accessible except in limited circumstances.
