By Elena Giannattasio, International Family Lawyer in New York, Multi-Jurisdictional Divorce, PLLC
Prenuptial agreements are fully enforceable in Finland, and spouses may also elect in advance which jurisdiction’s law will govern their marriage, provided at least one spouse has a nationality or domicile connection with the chosen country.
Formal requirements are strict:
● The agreement must be in writing,
● Dated and signed by both parties,
● Witnessed by two disinterested individuals, and
● Submitted to the Local Register Office (Maistraatti).
The prenup does not become valid until formally registered. These procedural steps are essential for enforceability, particularly where international mobility is expected.
