What does Monaco citizenship mean?
Monaco citizenship, or Monegasque nationality, is the legal bond between a person and the Principality. It is governed by Act no. 1.155 of 18 December 1992, amended since by later acts (no. 1.276 of 2003, no. 1.296 of 2005 and no. 1.387 of 2011).
The rule is based mainly on descent. Birth in Monaco gives no right to nationality, except for a child born to unknown parents. Many residents of the Principality hold a residence permit and keep their own nationality, so citizenship and residency are two separate topics.
Ways to acquire Monegasque nationality
The official public service portal of the Principality lists the routes below. None of them rests on an investment or on the purchase of a property.
| Route | Main condition | Nature of the decision |
|---|---|---|
| Descent from a Monegasque father | The child of a Monegasque father is Monegasque | By law |
| Descent from a Monegasque mother | The mother is Monegasque by birth, ancestry, naturalisation, reinstatement or declaration | By law, from birth |
| Marriage to a Monegasque national | Twenty years of marriage with a shared home; ten years for a marriage before 1 July 2022 | Declaration |
| Naturalisation | A minimum of ten years of ordinary residence after the age of 18, and renunciation of the previous nationality | Discretionary decision of the Sovereign Prince |
| Declaration after birth in Monaco | Birth in Monaco to a parent born Monegasque, with proof of residence in the Principality during childhood | Declaration after the age of 18 |
| Adoption | Plenary adoption gives the same rights as a biological child; simple adoption opens an option during minority | By law or by option |
| Reinstatement | A former Monegasque asks to recover nationality | Sovereign Ordinance |
Naturalisation in Monaco: conditions and procedure
Naturalisation is the route that concerns many foreign residents. The public service portal states that it is at the discretion of the Sovereign Prince: meeting the conditions opens the file but guarantees no result.
The residence requirement
The applicant has lived in Monaco for a minimum of ten years after the age of 18. One source specifies that the residence is continuous. The Sovereign Prince grants a dispensation from this duration for applicants he considers worthy of the favour.
Renunciation and military service
Before the Sovereign Ordinance is signed, the applicant is exempt from military service in the country of origin and renounces the previous nationality. One source indicates that the renunciation takes place within six months of a positive decision. The Department of Justice confirms the timing for your situation.
The decision and the procedure
The application is addressed to the Prince on stamped paper. The Department of Justice examines it and reports to the Sovereign Prince. The French authorities are consulted on applications that receive a favourable response, before publication.
The criteria usually applied are family ties with the Monegasque community, integration into economic, social or cultural life, and the favourable opinion of the Prince. Children under 18 are covered by the naturalisation of a parent.
The Department of Justice receives enquiries at the Palais de Justice, 5 rue Colonel Bellando de Castro, MC 98000 Monaco, telephone (+377) 98 98 88 11. The official page does not list language or criminal record requirements, so ask the department before you prepare a file.
Citizenship by marriage to a Monegasque national
Marriage does not change nationality on its own. The foreign spouse acquires nationality by declaration after twenty years of marriage, or ten years for a marriage celebrated before 1 July 2022. The rules require that:
- The couple still lives together, with an exception for the widowed spouse who has not remarried
- The spouse did not obtain nationality through an earlier marriage
- The acquisition causes no loss of the original nationality under foreign law or an international convention
- The Monegasque spouse still holds nationality on the day of the application
A declaration follows rules set by law and differs from the discretionary naturalisation. A person who obtains nationality by marriage keeps the original nationality.
Citizenship, residency and property: three separate statuses
Many questions mix three notions. The table separates them.
| Status | What it gives | How you obtain it | Link with property |
|---|---|---|---|
| Residence permit | The right to live in the Principality | Proof of housing, proof of means and a bank reference | A rental contract or a title deed serves as housing proof |
| Property ownership | The right to use and sell a property | A deed signed before a Monegasque notary | A purchase does not grant a residence permit by itself |
| Monegasque nationality | Legal bond with the Principality | Descent, marriage, naturalisation, adoption or reinstatement | No route is based on a purchase |
For a first residence permit, Monegasque banks commonly ask for around €500,000 held in a Monaco bank when the applicant has no professional income. No law sets this amount, and a salary, a professional income or the support of a resident relative also serve as proof of means. These conditions concern residency, not nationality.
The ten years required for naturalisation are years of ordinary residence. A stable home in the Principality, rented or owned, is the base of any later application.
Dual nationality and loss of nationality
Naturalisation requires the renunciation of foreign nationalities, so a naturalised citizen holds the Monegasque nationality alone. A person who acquires nationality by marriage keeps the original nationality.
Monegasque nationality is lost in three cases: the voluntary acquisition of a foreign nationality, foreign military service without the prior authorisation of the government, and acts deemed to harm the internal or external security of the Principality. A citizen is free to renounce nationality, and a former citizen asks the Prince for reinstatement.
The Monegasque passport
A 2026 passport ranking cited by encyclopaedic sources places the Monegasque passport in 12th position, with visa-free or visa-on-arrival access to 176 countries and territories. Rankings change from one year to the next, so check the current figure before you plan travel.
