Law n°1448 of 28 june 2017 regarding International Private Law was published last friday in the Monaco official gazette. This new law is quite complex and covers jurisdiction of the Monaco courts, recognition of foreign judgments and foreign public deeds, conflicts of laws, personal status, marriage (in particular matrimonial regime, divorce and separation…), filiation and adoption, alimony and financial compensation, estates, contractual and non contractual obligations, assets, trusts. Among other things the new law allows the parties to choose the law applicable to their matrimonial regime, their divorce, and their estate. It conveys substantial changes in Monaco practice. We now need to see how the courts will understand the new provisions.
