    Beneficial Ownership Verification

    Real estate agents, lawyers, property developers7 min readVersion 1.0Updated June 2026

    Why this matters

    Property is frequently used to hold or move value through corporate structures. Without identifying the real human beneficiaries, AML controls fail at the most important point.

    Spanish AML regulation requires obligated subjects to identify and verify the ultimate beneficial owner — not only the named client.

    Practical implementation

    Ownership chain

    Map the full ownership structure — every shareholding entity between the client and the ultimate natural person owners.

    Threshold

    Apply the 25% ownership or control threshold, while remaining alert to control exercised through other means.

    Verification

    Verify the identity of each beneficial owner using independent documents — not only declarations.

    Trusts and foundations

    Identify settlors, trustees, protectors and beneficiaries, applying additional scrutiny where structures lack transparency.

    How PropComply helps

    • Guided capture of ownership chains for legal entities.
    • Identification and screening of each beneficial owner.
    • Storage of corporate documents, shareholder registers and ownership declarations in one structured file.
    • Clear visualisation of the structure for inspection readiness.

    PropComply supports — but does not replace — professional judgement, and does not guarantee AML compliance. Each obligated subject remains responsible for its own AML decisions.

    Practical example

    A two-layer corporate buyer

    A Spanish SL is 100% owned by a Luxembourg holding company, which in turn is owned 60/40 by two individuals.

    PropComply captures the full chain, identifies both individuals as ultimate beneficial owners, screens them, and stores supporting corporate documents.

    The file clearly shows who ultimately benefits from the transaction.

    Best practice

    • ·Re-verify beneficial ownership at trigger events such as restructuring.
