The most important person in a fund structure may not be the investor with the biggest allocation.

That is the mistake a static unit-holder register invites. It gives a compliance team a neat percentage, a legal name and the satisfying feeling that the question has been answered. But a fund-of-funds, a family office investing through an SPV, an offshore trust, a nominee or a partnership can separate economic interest from the ability to set investment policy or control the fund's activity. A chart that stops at the unit-holder level may be tidy. It may still be incomplete.

That distinction matters under the new EU Anti-Money Laundering Regulation, or AMLR. From 10 July 2027, the Regulation applies directly across Member States. Its beneficial-ownership rules include a specific test for collective investment undertakings, recognising that funds do not look or operate like ordinary trading companies. Regulation (EU) 2024/1624 does not ask funds to create a more elaborate org chart. It asks them to understand where ownership and control actually sit.

Article 61 requires a fund-specific test

Article 61 identifies a beneficial owner of a collective investment undertaking as a natural person who satisfies one or more of three conditions:

1. Holds, directly or indirectly, 25% or more of the units in the collective investment undertaking.

2. Has the ability to define or influence its investment policy.

3. Controls the undertaking's activities through other means.

The first limb will be familiar. It is measurable, and in a straightforward vehicle it may be the most efficient place to start. The second and third limbs are what make the provision fund-specific. They require the team to consider governance rights, reserved matters, appointment rights, investment-committee powers and any other route through which a natural person can determine how the vehicle behaves.

The three conditions are alternatives, not a sequence of fallbacks. A person can therefore be relevant even where their direct or indirect holding is below 25%, if they can influence policy or control the activity by another means. Conversely, a person crossing the ownership threshold should not end the analysis. The file should still explain the ownership path, the identity of the individual and the evidence supporting the conclusion.

This is one reason that it helps to separate two questions which are often collapsed into one.

1. Who is the beneficial owner of the fund itself?

2. When a legal entity subscribes to the fund, who owns or controls that investor?

The second is an investor-onboarding question. The first is a fund-governance question. Both can involve the same people and documents, but they are not interchangeable. KYB is not simply KYC applied to a company for precisely this reason: ownership and control need to be followed through each layer rather than inferred from one document.

Why structure charts miss the real controller

A traditional chart tends to privilege legal ownership because it is visible. Cap-table exports, register extracts and subscription records are useful evidence. They are not always decisive evidence.

Consider a closed-ended vehicle with several institutional investors, no investor above the 25% threshold and an investment committee with a narrow group of decision-makers. The unit-holder calculation may identify no beneficial owner under the first limb. The next question is not whether the exercise is finished. It is whether any natural person can define or influence investment policy, or control the vehicle by other means.

The answer is found in the governing documents and the operating reality. A team may need to examine the limited-partnership agreement or articles, side letters, reserved-matters schedules, delegation arrangements, investment-advisory terms and appointment or removal rights. The right evidence depends on the structure. The discipline is consistent: connect each claimed source of control to the natural person who can exercise it, and record why it is or is not relevant to the Article 61 test.

That is a useful test of whether a process is genuinely risk-based. If an investment committee has policy influence, the process should be able to capture that role even when it is absent from the ownership register. If a large unit-holder cannot influence policy, the file should state why the percentage alone did not settle the wider analysis. A defensible conclusion is a conclusion another reviewer can retrace.

Build a fund control map, then maintain it

The practical output should be a control map, not a bundle of ownership documents. A good map makes five things visible.

The vehicle. Record the fund's legal form, jurisdiction and the governing documents that establish its framework. The form matters because the relevant routes to control may differ between, for example, a corporate fund, a limited partnership and a contractual arrangement.

The ownership path. Calculate direct and indirect unit holdings and show how each material interest is held. This is where feeder funds, SPVs, nominees, trusts and partnerships need to be traversed rather than represented as a single opaque box.

The policy path. Identify the bodies and individuals that can define or influence investment policy. The aim is not to label every director, adviser or service provider as a beneficial owner. It is to test the legal and practical powers that actually matter.

The other-control path. Record rights or relationships that can control the fund's activity without taking the form of unit ownership. The question should be documented against the vehicle's own constitutional documents and operating model, not answered from a generic template.

The evidence and decision. Attach the source document, relevant provision, date checked, reviewer, conclusion and any uncertainty. Article 62 requires beneficial-ownership information to be adequate, accurate and up to date. Where a particular fund vehicle is subject to the legal-entity obligations in that Article, it also sets expectations for prompt updates and annual verification. The operational lesson is broader: ownership intelligence must have a maintenance path, not a creation date.

That maintenance path should be triggered by events, not only a calendar. A new feeder, change of general partner, revised investment-advisory mandate, alteration to reserved matters or change of a controlling individual can all reopen the analysis. Europe's new AML regime for funds is moving the conversation towards more consistent controls across the Union. A fund's structure file needs to be capable of responding when the underlying facts change.

What an ownership-intelligence workflow looks like

The best ownership workflows do not begin by asking an analyst to redraw a structure from scratch. They begin by making each document and relationship usable as evidence.

First, intake should distinguish the documents that establish the vehicle, the documents that evidence ownership and the documents that allocate governance rights. That makes it easier to see whether an open question is really about a missing register extract, a missing side letter or an unreviewed delegation clause.

Second, the workflow should turn the legal test into explicit review questions. Does an individual meet the 25% unit-holding condition? Can they define or influence investment policy? Do they control the activity by another means? Each answer should have a route to evidence, a named reviewer and an escalation path where the documents conflict or leave a material gap.

Third, the map should remain connected to the wider compliance workflow. A change in an ownership record can create a company-verification task, require a new identity check, alter the risk assessment or prompt additional PEP and sanctions screening. The relationship should be visible in one case, rather than reconstructed from a shared drive, several inboxes and a spreadsheet that may already be out of date.

This is where purpose-built, AI-first systems can make the regulation operational. Steward's document-first workflow can extract structured entity information, map ownership and control across complex structures, and route exceptions to the right reviewer. Case management supports assigned company-verification and screening tasks during onboarding, then supports ongoing-monitoring and periodic-review work after approval. Human reviewers retain oversight of the conclusions, while the evidence and rationale remain part of the record.

The aim is not to make beneficial ownership a background data exercise. It is to make it a controlled decision that can survive a changed structure, a new reviewer or supervisory scrutiny. In a fund environment, the decisive control path is often the one a percentage-only chart cannot show.
