Marrying a Millionaire: What Your Prenup Should Cover

Reading time: 5 minutes
If you want to marry a millionaire, you can't avoid a topic many women would rather push aside: the prenuptial agreement. It sounds unromantic, but it's exactly the opposite. A good prenup doesn't just protect his assets, but also your future, your work and your dignity within the marriage. If you raise the topic clearly from the start, you negotiate from a stronger position than someone who only gets up the nerve to ask questions late in the game.
In this article you'll get a realistic overview of which points belong in such an agreement and what to pay particular attention to before you sign.
Marrying a Millionaire: Why the Prenup Protects Both Sides
Many women think a prenup only serves to protect the wealthy partner. That's only half true. If you want to marry a millionaire, you should know that a well-thought-out agreement also secures your own position, for instance when you give up a career, take on childcare or make joint investments.
Without clear arrangements, a divorce can turn into years of disputes, especially when business shares or real estate are involved. In Switzerland, the Civil Code (ZGB) governs the marital property regime and the consequences of divorce if there is no prenup, as you can read at the Federal Office of Justice at bj.admin.ch. A tailored agreement can adjust many of these default statutory rules in a targeted way.
The Difference Between Feelings and Legal Reality
Especially at the start of a relationship with a wealthy partner, a prenup can feel like distrust. In fact, it's more of a stress test for the relationship itself. If you can talk openly about money, expectations and protection, you lay the foundation for trust, not for doubt.
Marital Property Regimes in a Millionaire Marriage: Understanding the Three Basic Models
Before getting into details, the marital property regime has to be settled. It's the basis of every prenup and decides who owns what during and after the marriage.
- Separation of property: Each partner keeps their assets entirely separate, and any increase in value during the marriage remains individually assigned.
- Participation in acquired property: The statutory default in Switzerland, under which only the assets earned during the marriage are shared, not the assets each partner brought into it.
- Community of property: Almost all of both partners' assets become joint property, which is rarely chosen when assets are very unequal.
If you want to marry a millionaire and are thinking about long-term security, you should understand these three models thoroughly before a notary gets involved. The choice of marital property regime also has a considerable effect on inheritance questions later.
Why Separation of Property Is Often Preferred
When assets are very unequal, many wealthy men choose separation of property to protect their company or family fortune. That doesn't have to be a disadvantage for the partner, as long as the agreement also sets out additional compensation payments or maintenance arrangements.
Marrying a Millionaire: What Belongs in Every Prenup

A prenup is more than a list of assets. It should also cover life situations that can arise during the marriage.
- Rules on post-divorce maintenance if one partner scales back professionally
- Agreements on jointly owned property and who stays in the event of a separation
- A clear separation of business shares and business assets
- Rules on retirement provision, especially important if your career is interrupted
- How to handle gifts, jewelry or artworks during the marriage
If you plan to marry a millionaire, you shouldn't leave these points to your partner's lawyer alone. Independent legal advice of your own is not an option here, it's a must.
Clarify Your Own Interests Before Signing
Before you sign anything, it's worth talking through your own plans. Do you want to keep working, build assets of your own, or focus entirely on the family? This question directly affects what should go into the agreement. If you've already looked into building your own wealth alongside a rich partner, you'll negotiate with more clarity.
Marrying a Rich Man: Legal Protection Beyond the Contract
A prenup is the foundation, but it isn't everything. If you want to marry a rich man, you should also think about topics such as powers of attorney, a will and disclosure obligations under marital property law.
Especially with international assets, such as real estate abroad or business stakes in several countries, the legal situation becomes complex. A family law attorney experienced with wealthy clients is indispensable here. The State Secretariat for Economic Affairs SECO offers general information on commercial law topics in Switzerland at seco.admin.ch.
Your own identity should also be considered indirectly in the agreement. If you're wondering how to stay independent as a millionaire's partner, the article on independence as a millionaire's wife despite the luxury lifestyle offers valuable food for thought that can also be reflected in legal terms.
Finding a Wealthy Partner and Timing the Conversation About the Agreement

The right timing for the prenup conversation is almost as important as the content itself. Too early and it seems calculating, too late and there's no time for proper negotiations.
From experience, the moment after the engagement, but at least three months before the wedding, is a good time. That leaves enough room to negotiate without time pressure. If you want to find a wealthy partner and stay by his side for the long term, you shouldn't put off such conversations out of fear of conflict.
How the topic is raised also matters. A factual, calm conversation between equals signals maturity, not distrust. If you're already practiced at talking about expectations in your first serious conversation, this will come more easily. More on this in the article about clarifying expectations after the third date.
Avoiding Typical Negotiation Mistakes
Many women sign contracts presented by their partner's lawyer without getting advice of their own. That is the most common mistake. A second common mistake is mixing emotions and legal questions instead of keeping them clearly separate.
Conclusion: Marrying a Millionaire With Clarity Instead of Illusions
If you want to marry a millionaire, you should see the prenup as a tool, not an obstacle. It creates clarity for both sides and protects against nasty surprises if your paths part.
Take the time to get advice of your own, and talk openly about the marital property regime, maintenance and asset questions before you sign. If you also want to look at the realistic side of life alongside a wealthy partner, take a look at the article Marrying Rich: What Really Awaits You.
