# List owners

> Retrieve the natural persons declared as ultimate beneficial owners of a merchant, with their ownership percentage and verification status.

Ultimate beneficial owners (UBOs) are the natural persons who ultimately own or control a merchant entity. Under EU anti-money laundering regulations, Tilta requires qualifying owners to be declared before a merchant can complete onboarding.

Use this endpoint to review the declared ownership structure and where each owner stands in verification.
