Update of Monaco's code of International Private Law - Bill No. 272:

23/10/2025
Eight years after the entry into force of the 2017 Code of International Private Law, Bill No. 272 aims to update certain provisions in order to increase legal certainty and better harmonise Monegasque law with international standards. This text, supported by 20 members of the Conseil National, has not yet been adopted as law but reflects a desire to proactively adapt the Principality's law.
 

Main objectives

The reform has two objectives:
  • To enhance legal predictability for international families and professionals living in Monaco.
  • Ensure unilateral coordination of Monegasque law with international (particularly European) standards and case law.


1. International public policy: towards a more precise framework

The proposal clarifies the concept of "Monegasque international public policy". Until now, this expression appeared in the Code without a clear definition, leading to confusion with domestic public policy.
The text introduces the following concepts:
  • International public policy refers to the fundamental principles of Monegasque law.
  • Contradiction with these principles must be manifest in order to rule out the application of a foreign law.
  • Monegasque judges must take into account rights acquired abroad, unless their recognition would clearly violate these principles.
Monaco would thus enshrine the doctrine of mitigated public policy, already accepted in case law and in several European codes.


2. International successions: simplification and consistency

Two major measures are proposed:
  • Abolition of a rule on the reserved portion of an estate (Art. 63, paragraph 2), which is considered complex and a source of inconsistency. This would allow for the full application of a single law to the entire estate, as in European Regulation No. 650/2012.
  • Jurisdiction of the Monegasque court to issue certain documents necessary for the opening and administration of an estate when the applicable law is foreign. This measure addresses the difficulties posed by successions governed by common law, particularly where it is impossible to obtain probate for practical reasons.


3. International gifts: securing transfers

The text introduces clear conflict-of-law rules for gifts:
  • In the absence of a choice, the applicable law would be that of the donor's domicile.
  • For property donations relating to property located in Monaco, Monegasque law would apply without exception.
This clarification was eagerly awaited by practitioners in a context of increased wealth accumulation.


4. Transitional provisions: greater clarity

The draft introduces a new Title VI to the Code, setting out the following principles:
  • The Code applies from 8 July 2017, unless otherwise specified.
  • Procedures in progress on that date remain governed by the old law.
  • The specific dates of entry into force of certain provisions (adoption, consumption, succession) are also listed.

 

This proposal illustrates the desire of the Monegasque National Council to maintain a modern, stable and responsive private international law that is in tune with the diversity of international situations present in Monaco. If adopted, it will strengthen legal certainty for families in a globalised world. Certain points may require clarification as the bill progresses, such as its interaction with Law 214. For the time being, this is a proposed law.
If the law is adopted, families will need to review their estate planning and wills to ensure that they still meet their needs.
