The Prince

An independent sovereign state, the Principality of Monaco is governed by the Constitution of 17 December 1962, which defines its government as a Hereditary Constitutional Monarchy. The Prince is the Head of State and represents the Principality in its relationships with foreign powers. He signs and ratifies treaties. Succession to the throne proceeds via direct and legitimate descendance from the reigning Prince by order of primogeniture.


Priority is given, in the case of the same levels of kinship, to male descendants.  In the absence of legitimate descendance, an adopted child may accede to the throne. The Hereditary Prince may not exercise his powers until aged 21. Until his majority, power is assumed by a Regency. In certain matters, the Prince is assisted by purely consultative assemblies: Crown’s Counsel, the Council of State.

The Institutions

The Prinicipality’s political and institutional regime is governed by the Constitution of 17 December 1962 (modified by Law N° 1.249 passed on 2 April 2002). A cornerstone law of the State, it defines the nature of the Government,  the organisation of public authorities and their relationships. It also consecrates the public rights and liberties granted to Monegasques and foreigners.


The Principality is a hereditary and constitutional monarchy which attests to the supremacy of the law over all the institutions and ensures separation of powers.


Thus it is that executive power depends on the high authority of the Prince, with management of services being entrusted to the Minister of State, assisted by Government Counsellors who in turn answer to the Prince. Legislative and budgetary powers are exercised jointly by the Prince and the National Council. Finally, judiciary power, independent of the Government,  is exercised by the courts and tribunals.
