Monaco · Citizenship by naturalisation
Monégasque Naturalisation by Sovereign Ordinance
Open
Last verified July 2026
Legally open, practically closed. Roughly 20 naturalisations by Sovereign Ordinance in 2025 and 11 in 2024. No amount of money creates an entitlement — the decision is the Prince's personal prerogative.
We include this to close the question rather than to sell it. In 2025, about 20 people were naturalised out of a Monégasque population under 10,000. Around 55% of new Monégasques acquire it by filiation and 33% by marriage — naturalisation is a rounding error, and the mandatory renunciation of your existing citizenship makes it a bad trade even if offered.

What can go wrong
- You must renounce all other nationalities, typically within 6 months of approval.
- Purely discretionary. Meeting every published criterion creates no right and no appeal.
- Naturalisation rates collapsed after a domestic political backlash around 2009–2011 and have never recovered to the 40–64 per year seen in 2005–2008.
- Anyone marketing 'Monaco citizenship' as a product is selling something that does not exist.
