Monaco is barely two square kilometres, holds what is often called the world's highest concentration of millionaires and billionaires, and charges its residents no income tax. In June 2024 it was added to the FATF grey list. That collision — extreme private wealth against a watchdog's verdict that the controls weren't working — is the backdrop to every beneficial-ownership question you will ask about a Monaco entity.
01Why Monaco is different
Monaco's economy is built almost entirely on holding and managing wealth: private banking, family offices, real estate, yachts, and the legal structures that wrap them. Residents other than French nationals pay no income tax, and the principality recorded a GDP of around €10.24 billion in 2024 from a population of fewer than 40,000. That makes it a magnet for exactly the structures — civil property companies, foreign trusts, holding vehicles — that compliance teams find hardest to see through.
None of this means Monaco is opaque by intent in 2026. It now runs a central beneficial-owner register, a separate register of trusts, and one of Europe's more aggressive enforcement authorities. But the structures it specialises in — and the way access to the data is gated — mean that verifying a Monaco UBO from outside is a specific discipline, not a generic registry lookup.
02How the richest square mile got grey-listed
The story starts with MONEYVAL, the Council of Europe body that evaluates Monaco against the FATF standard. Its fifth-round mutual evaluation, published in December 2022, found the effectiveness of Monaco's system "uneven" and told the principality to step up its efforts — flagging weaknesses in how money-laundering cases were investigated and prosecuted, in the pursuit of proceeds from fraud committed abroad, and in the seizure and confiscation of criminal assets.
Despite a reform push, the FATF concluded on 28 June 2024 that the gaps were not yet closed and placed Monaco under increased monitoring — the grey list. The point worth holding onto: Monaco was not listed because its laws were missing. It was listed because the system was not yet demonstrably effective — the hardest thing for any jurisdiction to prove, and the thing a wealth centre with cross-border structures finds hardest of all.
03The reform sprint: SICCFIN becomes the AMSF
Monaco's response was unusually fast. Over roughly sixteen months it passed four major legislative packages totalling 481 articles, amending eleven laws, a sovereign ordinance and three legal codes. The structural centrepiece was the replacement of the old financial-circuits service, SICCFIN, with the AMSF (Autorité Monégasque de Sécurité Financière) — an independent authority that combines the financial-intelligence-unit and AML/CFT supervisory roles, with its own power to investigate and sanction. The AMSF became operational in 2023 and is a member of the Egmont Group of financial intelligence units.
For anyone verifying a Monaco entity, the AMSF is the centre of gravity. It supervises the banks, trustees, real-estate agents and other obliged entities that actually hold the beneficial-ownership data, and — as the penalties section shows — it has started using its sanctioning power in public.
04The framework: Law 1.362 and the register at the RCI
Monaco's beneficial-ownership regime sits in Law No. 1.362 of 3 August 2009 on the fight against money laundering, terrorist financing and corruption, as amended — in particular by Law No. 1.462 of 28 June 2018, which created the beneficial-owner register, and its implementing Sovereign Ordinances (notably No. 2.318). The register of beneficial owners is annexed to the RCI — the Répertoire du Commerce et de l'Industrie (Trade and Industry Directory) — and administered within the Department of Economic Development.
One structural point matters before anything else: Monaco is not in the EU or the EEA. Unlike Liechtenstein, it does not implement the EU Anti-Money Laundering Directives. It shares a customs and monetary union with France and uses the euro, but its AML framework is its own, built to the FATF standard and policed by MONEYVAL. So the rules below resemble the EU model — a 25% threshold, a central register — without being bound by it.
05Who counts as a beneficial owner
The definition follows the familiar cascade, set out in Law 1.362 and its ordinances.
06What the register records — and by when
Each entity must file a defined set of identifying data on every beneficial owner, and must name a designated officer responsible for keeping it current. The timing obligations are tight: the declaration is made when the entity registers with the RCI, or within fifteen days of the registration receipt, and any change must be updated within thirty days — independently of annual or tax filings. Pre-existing entities had to file by 28 June 2020.
| Field | Recorded? | Note |
|---|---|---|
| Surname and first name | Yes | The natural person identified as a beneficial owner |
| Date (and place) of birth | Yes | Place of birth is also captured for certain parties |
| Nationality | Yes | Including multiple nationalities where they apply |
| Personal address | Yes | Residential address of the beneficial owner |
| Nature and extent of control | Yes | Owner above 25%, controller, or legal representative |
| Designated information officer | Named to the RCI | The person responsible for the basic and beneficial-owner information |
07The entities in scope
The declaration obligation reaches further than trading companies. It covers commercial companies, economic interest groupings, and — critically — the non-trading civil companies that hold so much of Monaco's wealth.
| Entity | In scope? | Note |
|---|---|---|
| SAM (Société Anonyme Monégasque) | Yes | The Monegasque public limited company |
| SARL / SNC / SCS | Yes | Limited-liability and partnership forms |
| Economic interest groupings (GIE) | Yes | Registered with the RCI |
| Civil companies — incl. SCI | Yes | Non-trading companies in the RCI's special register — the real-estate vehicles |
| Trusts (Law 214 and foreign) | Separate register | Declared to the Register of Trusts, not the company BO register |
08Real estate and the SCI: Monaco's opacity vector
The SCI (Société Civile Immobilière) is a non-trading civil company used to hold real estate — a Monaco apartment, or property in France held by a Monaco resident. It is the classic way to own valuable real estate through a company rather than in a personal name, and in a market like Monaco's that is the default, not the exception.
For a verifier, the SCI is both the problem and the opportunity. The problem: the building you care about is owned by a company, and the people behind that company may sit at the end of a chain that runs through France, Luxembourg or an offshore holdco. The opportunity: because the SCI is registered with the RCI and falls within the beneficial-ownership obligation, there is a declared beneficial owner to find — and real estate is precisely where the AMSF is concentrating its enforcement. The structure that was built for privacy is now the structure most likely to draw a supervisory eye.
Two complications make the real-estate case harder than the rule suggests. First, much Monaco and French property is held not through a Monaco SCI but through a French SCI or a Luxembourg or offshore holding company — entities registered in their home jurisdiction, whose beneficial owner sits in the French or Luxembourg register, not Monaco's. Second, even where the SCI is Monegasque, its data is confidential: non-trading civil companies (the SCI and SCP) sit in a special register that is not openly accessible the way trading companies are. So the property-ownership question routes either out of Monaco entirely, or into a special register you cannot freely search — on top of the restricted beneficial-owner annex. Where a trust holds Monaco real estate, separate obligations apply under Law No. 1.381.
09Searching the RCI: what's actually reachable
Monaco's company register, the RCI, dates to 1955 and is run by the Department of Economic Development. For trading companies, it is genuinely usable: you can search the register and download a certified extract online, around the clock, through the official tele-service portal.
| What you want | Available? | How |
|---|---|---|
| Trading company exists, type, office, management, status | Yes | Search and certified extract via the official RCI tele-service, 24/7 |
| RCI registration number | Yes | Eight characters: year, P or S, then five digits |
| Civil company data (SCI / SCP) | Confidential | Non-trading companies sit in a special register, not openly accessible |
| Annual accounts | Not public | Filed with the RCI but not publicly available |
| Beneficial owners | Restricted | The annexed BO register is gated — see the access section |
10Trusts: the "trust 214" regime
Monaco is a civil-law country with no domestic concept of the trust — but it has recognised foreign trusts since Law No. 214 of 27 February 1936 (revising Law No. 207 of 1935). A "trust 214" lets a foreign national resident in Monaco, whose own national law recognises trusts, create an inter vivos or testamentary trust under that foreign law, or transfer an existing foreign trust into Monaco — a Jersey trust, for instance, can be moved to the principality under this law. Monaco also acceded to the Hague Trust Convention, in force there since 2008.
Trusts do not sit in the company BO register; they have their own Register of Trusts, held by the Department of Economic Development, with obligations reinforced by Law No. 1.559 of 29 February 2024, including an annual declaration confirming whether the beneficial owners have changed. The beneficial owners of a trust are the usual cast.
| Party | Beneficial owner? | Note |
|---|---|---|
| Settlor | Yes | The person who places assets in the trust |
| Trustee(s) | Yes | Holds and administers the trust property |
| Protector | Where applicable | Can direct or veto the trustee — a control hook |
| Beneficiaries / class | Yes | Including a defined class where individuals aren't yet named |
| Anyone with effective control | Yes | The catch-all that picks up hidden control |
11Access to the data: the court-authorisation model
Monaco's access regime has a distinctive feature you will not find in most of Europe: legitimate-interest access runs through a judge.
| Who | Access | Basis |
|---|---|---|
| Monegasque authorities | Full | The AMSF, judicial authorities and tax-services agents |
| Obliged entities | For due diligence | Banks, trustees, agents and others performing CDD under the Law |
| Legitimate-interest applicants | Court-authorised | Granted only on authorisation by the President of the Court of First Instance |
| The general public | No access | No open beneficial-ownership search |
When the register is gated behind a judge, resolve the chain around it
You will not run an open search of Monaco's beneficial-owner register, and a legitimate-interest application goes through a court. What you can do is map the structure — the SCI or SAM, the trust above it, the holding layers in France, Luxembourg or offshore — and resolve the natural person at the top from the jurisdictions where the data is reachable. Zavia.ai connects directly to government registries in 100+ countries, follows ownership across borders, and returns an auditable map to the UBO with sanctions and PEP overlays, flagging where a civil company or trust breaks the trail.
12The MONEYVAL verdict: 39/40, yet still listed
The reform effort produced a striking technical result. In its first follow-up report of December 2024, MONEYVAL re-rated fifteen Recommendations in Monaco's favour.
And yet, through the June 2026 plenary, Monaco remained on the grey list. That is the lesson of this jurisdiction in one data point: a near-perfect technical scorecard does not buy removal, because the FATF is judging whether the action plan is delivered in practice — more investigations, more prosecutions, more assets actually seized. For a compliance team, the read-across is direct: do not treat Monaco's strong ratings as a reason to relax. The supervisor itself is being told to prove effectiveness, and it is pushing that pressure straight onto obliged entities.
13Penalties and the AMSF Sanctions Commission
The enforcement edge is real and recent. Breaches of the Law 1.362 obligations — including failures around beneficial-ownership identification and record-keeping — can draw administrative fines of up to €200,000, escalating to criminal penalties where breaches persist. The AMSF's Sanctions Commission has begun publishing decisions: in November 2025 it issued sanctions involving a real-estate agent and a high-value-asset broker, and the records that must underpin a filing have to be kept for ten years.
Those November 2025 decisions are worth reading as a signal of where the pressure lands: real estate and high-value assets, the very sectors that define Monaco. The supervisor is not policing abstract paperwork — it is policing the SCIs, the brokers and the source-of-funds checks behind the principality's signature transactions.
14Yachts and high-value movable assets
Real estate is only half the picture. Monaco is one of the world's great yachting capitals; through the summer its marina and bay fill with superyachts, and the brokers who sell them, the agents who manage them and the dealers in art and other high-value goods are all obliged entities. Movable assets are a distinct verification problem because, unlike a building, there is no property register — a yacht or an artwork is usually held through an offshore company, and ownership can move quietly across borders.
The AMSF's published 2025 sanctions made the point concrete. The decisions singled out yacht sales, crypto-funded purchases and complex cross-border structures as high-risk, and treated documented source of funds — not notoriety or a banker's letter — as the decisive control. For a verifier, a yacht or high-value-asset purchase behind a Monaco intermediary is two problems at once: a structure to unwind to the natural person, and a source-of-funds question that has to be answered with documents.
15Sanctions exposure: the Russian wealth question
Monaco's exposure to sanctioned wealth is not theoretical. Its bay has long hosted oligarch superyachts and its property market drew foreign buyers, so the 2022 sanctions wave landed squarely on its core sectors. The principality aligned without delay, adopting asset freezes and economic sanctions "identical to those taken by most European States" and freezing Russian-linked assets in step with the EU and France.
Mechanically, Monaco implements United Nations, European Union and French measures through a National List of persons and entities subject to a freeze of funds and economic resources, maintained by the Budget and Treasury Department; only the binding decisions of the Minister of State give the freeze legal effect. The implication for beneficial-ownership work is direct: in Monaco, resolving the UBO and screening it are inseparable. Identifying the natural person behind an SCI, trust or yacht-holding company is step one; checking that person and the structure against the National List and the underlying UN, EU and French regimes is the control that actually protects you.
16Source of wealth: the decisive control
In Monaco, the hardest part of verifying a beneficial owner is often not the name — it is proving where the money came from. The AMSF's published sanctions make clear that source-of-wealth and source-of-funds checks are the decisive issue, and that the bar is documentary, not anecdotal. Verbal explanations, press notoriety, a bank "good standing" letter on its own, or "long-standing client" assumptions have been treated as insufficient; what the supervisor accepts is reliable documentation — bank statements, audited accounts, tax returns, asset-sale or loan agreements — tied to the specific funds in the transaction.
The practical implication for cross-border teams is that identifying the natural person is step one, not the finish line. Once you have resolved the UBO behind a Monaco SCI, trust or SAM, the defensible file is the one that documents how that person came by the wealth funding the structure — and screens them against sanctions, PEP and adverse-media sources.
17Multi-layer structures: Monaco at the apex
Monaco rarely sits at the bottom of a chain. It is where the wealth lands — the family's property company, the trust, the holding vehicle — above operating businesses and offshore layers elsewhere.
18Common failure modes
The mistakes that recur on Monaco files almost all come from treating it like an ordinary EU jurisdiction.
| The mistake | Why it fails |
|---|---|
| Expecting an open public register | There is none — legitimate-interest access needs authorisation from a judge of the Court of First Instance |
| Treating Monaco as an EU/EEA state | It is neither; it runs its own framework to the FATF standard, not the AML Directives |
| Searching the RCI for an SCI | Civil-company data is confidential — the property vehicle won't appear like a trading company |
| Assuming the SCI is Monegasque | Much property is held through a French SCI or offshore holdco, whose BO sits in another register |
| Looking for a trust in the company register | Trusts sit in a separate Register of Trusts at the Department of Economic Development |
| Stopping at the legal representative | A filed manager often means no 25% owner was found — a prompt to dig, not a conclusion |
| Reading the 39/40 score as low risk | Strong technical compliance did not lift the grey-listing; effectiveness is still under scrutiny |
| Proving identity but not source of wealth | The AMSF treats documented source of funds as the decisive control, not the name alone |
19How to verify a Monaco UBO: workflow
A practical sequence for resolving a Monaco beneficial owner from outside the principality:
- Identify the structure. Is it a SAM, an SARL, an SCI or other civil company, or a trust? Trusts route to the Register of Trusts; everything else to the company BO register at the RCI.
- Pull what the RCI exposes. For a trading company, search and download a certified extract from the official RCI tele-service for its details and management. For an SCI, expect the civil-company data to be confidential — capture the administering professional instead.
- Apply the cascade. Test for a 25% owner, then for control by other means, and treat a filed legal representative as a flag to look further, not an answer.
- Follow the chain. Resolve any SCI, trust or holding layer above and below the Monaco entity — often through France, Luxembourg or an offshore register that is more open than Monaco's.
- Use the right access route. An obliged entity relies on its own due-diligence access and counterparty disclosure; legitimate-interest access to the register requires court authorisation.
- Document source of wealth, then screen. Evidence how the resolved person came by the funds with reliable documents, screen against sanctions — including Monaco's National List — PEP and adverse-media sources, and keep an auditable trail.
20Practical takeaways
| Scenario | What you can rely on | What you must supplement |
|---|---|---|
| Monaco SAM / SARL | RCI registration, management, declared BO | The chain above if a trust or holdco sits at the apex |
| SCI (property company) | Little — civil-company data is confidential | Upstream owners, the administering professional, and documented source of funds |
| Trust 214 / foreign trust | Register of Trusts; the trustee's records | Settlor, protector and beneficiaries — private, via the trustee or court-authorised access |
| Yacht / high-value asset | Identity of the parties to the deal | The offshore holding chain and a documented source of funds |
Monaco is the jurisdiction where the controls and the wealth are pulling against each other in real time. The data exists — a beneficial-owner register, a register of trusts, a tough new supervisor — but access is gated behind due-diligence status or a judge, the signature vehicles are civil property companies and foreign trusts, and the regulator's own pressure point is whether any of it works in practice. Build the workflow around the structure type, the regulated professional behind it, and a documented source of wealth — not around a public search that does not exist.

22Frequently asked questions
Does Monaco have a public beneficial ownership register?
No. Monaco maintains a register of beneficial owners, annexed to the Trade and Industry Directory (RCI) under Law 1.362, but it is not open to the public. Access is limited to Monegasque authorities (including the AMSF, judicial authorities and tax services), to obliged entities performing customer due diligence, and to applicants with a legitimate interest in fighting money laundering — and that last route requires authorisation from the President of the Court of First Instance.
Why was Monaco added to the FATF grey list?
On 28 June 2024 the FATF placed Monaco under increased monitoring. The grey-listing followed MONEYVAL's December 2022 evaluation, which rated the effectiveness of Monaco's system "uneven" and flagged weaknesses in investigating and prosecuting money laundering, in pursuing the proceeds of fraud committed abroad, and in seizing and confiscating criminal assets. The issue was effectiveness in practice, not missing laws — which is why a strong technical scorecard has not, by itself, secured removal.
Is Monaco still on the FATF grey list in 2026?
Yes. As of the June 2026 plenary Monaco remained on the FATF list of jurisdictions under increased monitoring, while working through the action plan agreed in 2024 with the aim of removal. Its technical compliance is strong — MONEYVAL re-rated it to 39 of 40 Recommendations Compliant or Largely Compliant in December 2024 — but the FATF is assessing whether the reforms are delivering results in practice before lifting the listing.
What is the beneficial ownership threshold in Monaco?
25%. A beneficial owner is any natural person who ultimately owns, directly or indirectly, at least 25% of a company's capital or voting rights. If no one meets that test, it is whoever exercises effective control by other means — such as the power to appoint or dismiss the majority of the management bodies. If neither applies, the company's legal representative (the manager or managing director) is registered instead.
Can I search the Monaco company register online?
For trading companies, yes. The Trade and Industry Directory (RCI), run by the Department of Economic Development, offers an official tele-service where you can search and download a certified extract around the clock — covering the entity's name, RCI number, legal form, registered office, management and status. But the data of non-trading civil companies, including the SCI and SCP used to hold real estate, is confidential, and the annexed beneficial-owner register is restricted. Annual accounts are filed but not public.
Do Monaco real-estate companies have to declare beneficial owners?
Yes. The Société Civile Immobilière (SCI) and other non-trading civil companies registered in the RCI's special register fall within the beneficial-ownership obligation. Because so much Monaco real estate is held through SCIs — and often through a French SCI or offshore holdco whose owner sits in another register — and because civil-company data is confidential, the property vehicle is usually the hardest structure to resolve, even though a declared beneficial owner exists on file.
How are trusts treated in Monaco?
Monaco has no domestic trust law but recognises foreign trusts under Law No. 214 of 1936, available to foreign nationals resident in Monaco whose own national law allows trusts. A foreign trust — from Jersey, for example — can even be transferred into Monaco. Trusts are recorded in a separate Register of Trusts at the Department of Economic Development, and their beneficial owners are the settlor, trustee(s), any protector, the beneficiaries or class, and anyone exercising effective control.
What is the AMSF?
The Autorité Monégasque de Sécurité Financière is Monaco's independent financial-intelligence unit and AML/CFT supervisor, created as part of the reform sprint to replace the former SICCFIN. It supervises banks, trustees, real-estate agents and other obliged entities, and its Sanctions Commission can impose penalties — including the November 2025 decisions against a real-estate agent and a high-value-asset broker. It is a member of the Egmont Group of financial intelligence units.
What are the penalties for beneficial ownership breaches in Monaco?
Breaches of the Law 1.362 obligations, including failures around beneficial-ownership identification and record-keeping, can draw administrative fines of up to €200,000, escalating to criminal penalties where breaches persist. Beneficial-ownership records and supporting documents must be kept for ten years. The AMSF's Sanctions Commission enforces these obligations and has begun publishing sanction decisions, concentrated on the real-estate and high-value-asset sectors.
Does Monaco enforce sanctions against Russian wealth?
Yes. Although Monaco is not in the EU, it aligned without delay with EU and French measures after the 2022 invasion of Ukraine, freezing Russian-linked assets. It implements United Nations, EU and French sanctions through a National List of persons and entities subject to a freeze of funds and economic resources, maintained by the Budget and Treasury Department, with binding effect given by decisions of the Minister of State. For beneficial-ownership work, that makes screening the resolved UBO against the National List an essential control.
