UBO
A UBO, Ultimate Beneficial Owner, is the natural person who ultimately owns or controls a legal entity, directly or through a chain of other entities, even when that person’s name appears on no public register.
KYB checks a business itself, its registration, its authorised representatives, but establishing who ultimately stands behind it is a separate and often harder step: ownership can run through several holding companies or trusts before it reaches a person. A UBO credential lets that chain be proven once, by the register or notary that established it, and then presented instantly to every counterparty that needs it afterwards, instead of each one re-tracing the ownership structure from scratch.
