Matrimonial Agreement Template for Switzerland

A Matrimonial Agreement under Swiss law allows you to define your property rights and financial arrangements during marriage, providing crucial legal clarity beyond the default statutory regime. This formal contract must comply with strict Swiss legal requirements and offers significant protection for couples with complex financial situations or international connections.

When do you need this document?

You need a Matrimonial Agreement when you want to deviate from Switzerland's default property regime of "participation in acquired property." This document is essential if you're entering marriage with substantial individual assets, own business interests, have children from previous relationships, or hold international property. The agreement is particularly valuable for entrepreneurs who want to protect their business from potential matrimonial claims, couples with significant wealth disparities, or those planning to acquire substantial assets during marriage. You can execute this agreement before marriage or at any time during your union, but it requires mutual consent and proper legal formalities.

Key legal considerations

Your Matrimonial Agreement must respect mandatory Swiss legal provisions, particularly forced heirship rights that protect children's inheritance claims. The document cannot completely exclude maintenance obligations between spouses or violate public policy principles. You can choose between three property regimes: separation of property (complete financial independence), community of property (shared ownership of most assets), or a modified participation regime with specific exclusions. The agreement should clearly define which assets remain individual property, how acquired assets are treated, debt responsibility allocation, and management powers for joint assets. Consider including provisions for international assets and potential future changes in circumstances, such as career changes or inheritance.

Legal requirements in Switzerland

Swiss Civil Code Article 184 mandates that Matrimonial Agreements must be executed as public deeds before a notary public, making simple private contracts legally insufficient. Both spouses must personally appear before the notary and sign the document, with proper identification and legal capacity verification. If either spouse doesn't speak the local language fluently, you'll need a certified translator present during execution. The notary will verify that both parties understand the agreement's implications and consequences. For international couples, Swiss Private International Law provisions may apply, particularly regarding choice of law and recognition in other jurisdictions. The agreement becomes effective immediately upon notarization and registration, though some cantons may have additional filing requirements. Consider that changes to your Matrimonial Agreement later also require the same formal notarial process, making careful initial drafting crucial for long-term effectiveness.
