Notaries: verifying beneficial owners before an authentic act
Notaries are on the front line to block money-laundering setups via companies. Incorporation, merger, share transfer, real estate sale: every act demands enhanced UBO due diligence. Here is the complete checklist to secure an authentic act without burdening practice.
In brief
Notaries are subject to the 18 September 2017 anti-money-laundering law (Article 5, 1°, point 28°). For every act involving a legal entity, they must verify the identity of beneficial owners, cross-check against sanctions and PEP lists, and preserve traceability. The FSMA and the National Chamber of Notaries have stepped up enforcement since 2024. Here is the practical checklist for 6 typical acts.
Why the notary is a critical checkpoint
Notaries execute acts that transfer or create wealth: that is precisely where fraudsters try to enter the system. Three typical schemes only a notary can block before they become legally enforceable:
The notary is the final safeguard before these operations become legally enforceable.
General UBO checklist before any act
For every act involving a legal entity:
| # | Check | Source |
|---|---|---|
| 1 | BCE identity (name, registered office, status, establishment units, age) | BCE / Company Belgium API |
| 2 | Current directors (board members, managers, daily management delegates) | BCE |
| 3 | Beneficial owners in the UBO register (consulted on the day of the act) | UBO register via professional access |
| 4 | Consistency of declared UBOs vs actual ownership cascade | Articles of association + share register |
| 5 | PEP screening on all UBOs and directors (FR/NL/EN/international source) | Official PEP lists + PEP screening tool |
| 6 | Sanctions screening (EU, UN, OFAC) on the company and all UBOs/directors | Official lists + AML sanctions tool |
| 7 | Documented source of funds (bank statements, notarial loan, inheritance, prior sale) | Documentation provided by the client |
| 8 | Consistency of BCE figures vs apparent wealth (signals of dormant company, negative equity, etc.) | NBB annual accounts |
If any of the 8 points fails, the act must not be executed as is — request additional documents, refuse, or file a suspicion report with the CFI.
Act 1 — Company incorporation
Specifics:
- UBO is determined by initial capital and shareholders' agreement
- For a BV/SRL 99% owned by an NV/SA parent, the UBO is to be sought above the parent (cascade)
- The notary verifies that the UBO will be declared in the UBO register within one month of incorporation (legal obligation)
Watch out for:
- Very low capital (€1) + very broad corporate purpose = clue of a shell being set up
- Contribution in kind not appraised by an auditor when the law requires it
- Non-Belgian directors with no economic presence in Belgium
Act 2 — Share transfer
Specifics:
- Change of ownership modifies UBOs → mandatory UBO register update within one month
- The notary must verify the identity of the transferee as if they were a new client (full KYC)
- If the transferee is a company, trace up to the natural persons
Watch out for:
- Atypically low transfer price relative to the value of the annual accounts — clue of an undeclared parallel payment
- Foreign transferee via screen company in a low-transparency jurisdiction
- Multiple rapid operations with the same transferor (the transferor cleaning their portfolio)
Act 3 — Capital increase
Specifics:
- A cash capital increase must be checked on source of funds
- A contribution-in-kind increase requires an auditor's report (Article 5:7 CSA)
- A majority change after the increase modifies the UBO → mandatory re-declaration
Watch out for:
- Cash contribution of a large round amount from a recently created foreign company
- Increase immediately followed by a dividend to the new majority holder (fund extraction)
- Strongly dilutive increase that changes the UBO without the client seeming aware
Act 4 — Real estate acquisition by a company
The most common Belgian money-laundering scheme. Maximum vigilance:
- Verify the buying company has a real economic activity consistent with the acquisition (signals of dormant company)
- Source of funds: bank statements over 6+ months minimum, clear link with documented activity
- Verify price / market consistency (abnormally high price suggests a setup)
- Enhanced UBO check: a real estate buyer via a company falls under enhanced due diligence
Act 5 — Merger or demerger
Specifics:
- A merger consolidates two UBO sets into one — check each before merger
- A demerger creates separate UBOs that must be declared within one month
- Special case: partial demerger of personal wealth via an interposed company is a forward transmission scheme sometimes used to avoid inheritance tax — check tax compliance
Watch out for:
- Merger with an old dormant company (seniority acquisition for a resurrected company)
- Notably unbalanced exchange ratio with no economic justification
- Companies with completely inconsistent activities being merged
Act 6 — Dissolution / liquidation
Specifics:
- In case of liquidation surplus, check consistency with the annual accounts
- If the company was dormant for a long time, ensure there is no hidden wealth
- The liquidator must be an identified, capable natural person
Watch out for:
- Dissolution immediately after a major real estate sale (proceeds not recycled into the company, indicator of extraction)
- Dissolution with a liquidation result very far from book equity
- Liquidator who is also liquidator of several other companies in a short period (nominee)
Documentation and traceability
For each act, the notary keeps in the file:
- A copy of the UBO consultation dated the day of the act
- A copy of PEP and sanctions screenings dated and with screenshots
- The bank statements proving source of funds (for wealth acts)
- The up-to-date articles and share register consulted
- The computed AML score and verdict
- Any CFI suspicion reports
This traceability is what protects the notary in case of FSMA review or subsequent judicial procedure. An "empty" AML file is a major disciplinary risk.
Practical automation
Many notarial offices now automate these checks:
- Enter the company's BCE number → the API returns identity + directors + UBO + financial scoring + AML score
- Automatic comparison of declared UBO vs ownership cascade
- Instant PEP/sanctions screening
- Generation of the PDF due diligence file ready to archive
The Company Belgium API exposes these functions in a single endpoint. For notaries already using eNotariat or sector-specific solutions, integration is done via REST with API key authentication. See also our article on AML risk assessment for the methodology applicable to regulated professions.
Frequently asked questions
Which notary is subject to AML obligations in Belgium?
All of them. The 18 September 2017 law (Article 5, 1°, point 28°) targets notaries without distinction. This covers titular notaries, associated notaries and notary candidates executing acts. The obligations apply to every act involving wealth transfer or creation of a legal entity — virtually all notarial activity. The FSMA and the National Chamber of Notaries exercise joint supervision.
What if the client refuses to provide source-of-funds documentation?
Refuse to execute the act. The 18 September 2017 law requires the notary to apply ongoing vigilance and not execute an operation if verification obligations have not been satisfied. The refusal must be documented in the client file. If the elements available to the notary constitute money-laundering suspicion, they must additionally file a suspicion report with the CFI (via the goAML portal), even if the act was not executed.
Is the UBO register reliable as the sole verification source?
No. The UBO register contains what companies have declared, not necessarily what is actually true. A false or outdated UBO declaration commits only the declarer — not the register. The notary must cross the UBO register with: the articles of association, the share register, any shareholders' agreements, and the physical identity of persons present at the act. If an inconsistency appears, that is a red flag warranting further investigation before execution.
How long must the due diligence file of an act be kept?
10 years from the end of the business relationship (Article 60 of the 18 September 2017 law). For a notary, the 'end of the relationship' with a client can be very late — a client sometimes returns 20 years later for an inheritance linked to a prior act. In practice, many notaries archive indefinitely in a structured archive. Digital traceability and time-stamped signing of AML documents make compliance much easier.
