Entering into marriage in Finland creates immediate legal and economic ties. Under the Finnish Marriage Act (Avioliittolaki 234/1929), marriage automatically grants each spouse a marital right (avio-oikeus) to half of the net total property owned by the other spouse upon the dissolution of the marriage—whether through divorce or the death of a partner.
For international couples, expatriates, and cross-border families, relying on default statutory rules can unintentionally expose pre-owned wealth, family inheritances, business assets, or foreign real estate to division. To alter this statutory marital property regime, spouses must execute a formal, legally binding Prenuptial Agreement (Avioehtosopimus).
Drafting a prenuptial agreement requires rigorous adherence to statutory formal requirements. Flawed wording, missing witness signatures, or failure to properly register the deed with the Digital and Population Data Services Agency (DVV) can render the agreement completely invalid.
VNL Toimisto delivers expert legal advisory and drafting services for Prenuptial Agreements in Finland, ensuring your domestic contracts withstand both Finnish legal scrutiny and international cross-border enforcement.

Core Elements of Finnish Marital Property Law
Understanding how Finnish law regulates spousal assets highlights why a prenuptial agreement is essential:
1. Scope and Structure of a Finnish Prenuptial Agreement (Avioehto)
Under Chapter 9 and 10 of the Finnish Marriage Act, spouses possess broad contractual freedom to tailor their property rights, provided the agreement is explicit and unequivocal:
Total Exclusion of Marital Rights: A standard full prenuptial agreement dictates that neither spouse has any marital right to the other’s property, whether acquired before or during the marriage. Upon divorce, each partner keeps their own net assets without equalization payments (tasausmaksu).
Partial Exclusion: Spouses may draft custom clauses stipulating that specific assets—such as a pre-owned enterprise, inherited real estate, or foreign property holdings—are excluded from marital division while keeping general default rules applicable to other assets.
Inheritance & Testamentary Interaction: While a prenuptial agreement protects assets during a divorce, its interplay with inheritance law upon death requires careful coordination alongside a valid will (testamentti).
2. Mandatory Statutory Formalities for Validity
A prenuptial agreement is not valid simply because it is signed by both parties. Under Finnish law, it must strictly satisfy four formal criteria:
Written Instrument: The agreement must be drawn up in writing, clearly defining the intentions of both prospective or current spouses.
Dual Signatures: Both parties must sign the document in person or through a legally authorized representative holding a specific mandate.
Independent Witnesses: The agreement must be signed and dated in the presence of two fully independent, competent witnesses who are at least 18 years of age. (Close relatives, spouses, or direct heirs are legally disqualified from acting as witnesses).
Mandatory Registration with DVV: The executed prenuptial agreement must be submitted to the Digital and Population Data Services Agency (DVV) for official registration. An unregistered prenuptial agreement holds no legal validity against third parties or upon the dissolution of marriage.
3. Cross-Border Considerations & International Couples
For international couples residing in Finland—such as Vietnamese nationals or dual-citizens—determining which country’s law governs marital property rights can be complex:
Applicable Law: Under European Union regulations (EU Regulation 2016/1103 on enhanced cooperation in the area of jurisdiction, applicable law, and the recognition and enforcement of decisions in matters of matrimonial property regimes), a couple’s marital property is governed by the laws of their first common habitual residence upon marriage, unless they explicitly choose otherwise.
Cross-Border Recognition: If a couple owns real estate or investments in Vietnam alongside assets in Finland, a Finnish prenuptial agreement must be carefully structured and translated to ensure compliance or compatibility with Vietnamese civil law requirements.

Frequently Asked Questions (FAQ)
Can a prenuptial agreement be signed after getting married?
Yes. A prenuptial agreement (avioehtosopimus) can be concluded either before the wedding or at any time during the marriage. Post-nuptial agreements carry the exact same legal weight as prenuptial agreements, provided they are properly witnessed and registered with the DVV.
Does a prenuptial agreement eliminate the obligation to pay alimony or child support?
No. A prenuptial agreement regulates solely the division of property (ositussopimus / omaisuuden erottelu) upon divorce or death. It has no legal bearing on child custody, child maintenance payments, or spousal maintenance obligations (elatusapu), which are governed independently under family law.
What happens if we forget to register the prenuptial agreement with DVV?
An unregistered prenuptial agreement is legally void. If the agreement is kept in a drawer without being registered at the DVV, the default statutory marital right (avio-oikeus) remains fully active, meaning assets will be split equally upon divorce regardless of what the written document states.
