Monaco Presumes You Live There

A Monegasque residence card does not establish that its holder lives in Monaco. It raises a presumption, and the statute says so in terms.

Article 2 of the Code of Private International Law, enacted by Law No. 1.448 of 28 June 2017, defines a person's domicile for the purposes of that Code as the place of his principal establishment, and then provides that a foreign national holding a residence permit is presumed, in the absence of evidence to the contrary, to be domiciled in the Principality. One clause carries the whole of the arrangement: in the absence of evidence to the contrary.

That is an unusually candid drafting choice. Monaco is not asserting that the card is the fact. It is saying the card is the ordinary proof of the fact, and that the fact remains open to contradiction. Everything a family later encounters follows from that sentence, because the question of where a life actually sits is then put, separately and on different evidence, by a series of authorities who are not obliged to agree.

The first test is the renewal

Anyone aged sixteen or over intending to stay in the Principality for more than three months, or to take up residence, must hold a residence permit. The Monegasque public service publishes the sequence: a temporary card valid for one year, an ordinary card valid for three years after three years of residence, and a privilege card valid for ten years after ten years of genuine residence, with a five-year card for the spouse of a Monegasque national after one year.

The structure matters more than the durations. For the first years the state re-asks the question annually, against fresh documents. A jurisdiction that renews yearly is a jurisdiction that has reserved the right to look again.

The second test is the state that was left

For one nationality the presumption is beside the point. Article 7 of the Franco-Monegasque tax convention of 18 May 1963 provides that individuals of French nationality who transfer their domicile or residence to Monaco, or who cannot show five years of habitual residence in Monaco at 13 October 1962, are liable to income tax in France as though domiciled or resident there. The French tax administration's published doctrine on the convention states the rule and the two dates without qualification.

Read alongside article 2 of the Code, the position is stark. Monaco presumes domicile from the card. France, for its own nationals, declines to draw the inference at all and substitutes nationality. Two states, one person, one address, two answers, and neither is wrong on its own terms.

The third test is the estate, and it is the one nobody arrives expecting

Article 56 of the Code provides that a succession is governed by the law of the State in which the deceased was domiciled at death. A family that has moved therefore expects Monegasque law to govern, and in the ordinary case it does.

Article 63 is where the expectation breaks. Its second paragraph provides that the law so applicable cannot have the effect of depriving an heir of the reserved share assured to him by the law of the State of which the deceased was a national at death, nor of applying a reserved share to the estate of a person whose national law does not recognise that regime.

Residence moves almost every connecting factor a family has. It does not move that one. A principal who has spent a decade rearranging his affairs around a Monegasque address may find that the share his children can claim is still measured by the law of the passport he never changed, and that a child of a different nationality is measured differently again. Article 65 completes the point: where a person settles property on trust, the application to the trust of its own governing law does not displace the law governing the succession.

The fourth test is who is allowed a trust at all

Monaco has recognised trusts since Law No. 214 of 27 February 1936. Article 1 permits persons who, by virtue of their personal status, have the faculty to dispose of their property during life or on death under a regime of trusts to do so in the Principality. Access is a function of the settlor's personal law, not of his address. Article 3 reserves to Monegasque law alone the determination and designation of trustees, drawn from a list maintained by the First President of the Court of Appeal on the Attorney General's proposal. Article 5 sends disputes to the Monegasque courts, which apply the foreign law without being bound by Monegasque public policy.

A resident whose national law does not know the institution cannot use the 1936 law. The card does not help him. His nationality decides.

The fifth test is the file

Monaco made a high-level political commitment in June 2024 to work with the Financial Action Task Force and MONEYVAL on the effectiveness of its anti-money-laundering regime, and it remains a jurisdiction under increased monitoring. In its statement of 19 June 2026 the Task Force recorded an initial determination that Monaco has substantially completed its action plan and warrants an on-site assessment to verify that implementation has begun and is being sustained.

The first reform listed is the one that matters here: strengthening the understanding of risk in relation to money laundering and income tax fraud committed abroad. A jurisdiction that has undertaken, in an international instrument, to understand foreign tax risk has undertaken to notice the gap between where a resident says he lives and where his affairs suggest he does. The substance question has become a compliance question, which means it is now asked by a bank rather than only by a court.

Density is an information condition

The Monaco Statistics Institute recorded 38,857 residents at the 2025 census and 65,117 salaried employees, on a territory of a little over two square kilometres. The working population is larger than the resident population, and both occupy an area a person can cross on foot.

The consequence is not a crime rate, and we will not argue from one. It is that presence is legible. In a place of that size a pattern of movement is observable without any effort being made to observe it, by people who have no interest in the principal at all and who will nonetheless mention what they saw. That is an information condition, and it is the same condition whether the observer is a neighbour, a journalist or a counterparty's researcher. What follows from it is a set of decisions about routine, staff and household disclosure, and those decisions are not published here.

What we do, and where we do not do it

We act for families whose residence, succession and household arrangements are exposed to Monaco. The work is documentary and analytical, and it is done alongside Monegasque counsel and notaries rather than in place of them.

We keep no office in Monaco, hold no Monegasque licence and do not practise Monegasque law. Nothing above is legal or tax advice; structures are designed alongside independent counsel in each relevant territory, and a principal considering one should take advice from an adviser unrelated to Privy Consul.

The succession half of a Monaco question sits under Succession, Continuity & Legacy Governance, the household half under Residential & Family Security, and the visibility half under Reputation Safeguarding & Digital Footprint Management. The same connecting-factor problem, argued from a different statute, appears in Swiss Banking Secrecy Was Never Repealed and The Flat Tax Moved the Income, Not the Law; what a file cannot hold is the subject of What Filings Never Record.
