# Update a UBO

<Warning>
  **Caution – Legacy endpoints being superseded by the hosted KYC/KYB solution**

  Mangopay's [hosted KYC/KYB solution](/guides/users/verification/hosted) is becoming mandatory for all platforms, and allows Legal Users to declare and verify all beneficial owners in the same [IDV Session](/api-reference/idv-sessions/idv-session-object) object.

  The [criteria defining beneficial owners](/guides/glossary#beneficial-owner-ubo) remain the same.
