Ever wondered what would happen to your hard-earned assets if your marriage didn’t work out? If you’re living in Portugal or getting married here, this isn’t just a theoretical question – it’s a practical one that deserves serious attention.
Many couples are too confident that their foreign prenuptial agreements would automatically protect them in Portugal. Unfortunately, that’s not always the case. Portuguese matrimonial law has its own peculiarities that can catch many international couples off guard.

1. The Reality of Marriage in Portugal
In Portugal, when you say “I do” you’re not just committing to your partner – you’re entering into a legal framework that automatically determines how your assets and debts are handled. Without a prenuptial agreement, the default system (called “comunhão de adquiridos”) means that assets acquired during the marriage become joint property regardless of who paid for them.
Many of my international clients are shocked by this. Last month I had a client who had built a substantial cryptocurrency portfolio who was stunned to learn that his investments could be considered joint property without proper protection.
2. When to Consider a Prenuptial Agreement
A prenuptial agreement isn’t just for the wealthy. Consider one if:
- You own a business or professional practice
- You have significant investments (including cryptocurrency)
- You expect to receive an inheritance
- You have children from a previous relationship
- You have existing debts you don’t want to burden your partner with
- You own property in multiple countries
I recently worked with a client who had a trust fund who wanted to ensure his future wife would be financially supported even if they divorced. His priority wasn’t protecting his assets from her but rather establishing a formal mechanism to share his trust fund income for years after a potential divorce – a thoughtful approach that required careful legal structuring.
3. Key Elements of a Valid Portuguese Prenuptial Agreement
For your prenuptial agreement to stand up to legal scrutiny in Portugal, it must:
- Be signed before the marriage
- Be formalized by a notary
- Be registered with the Portuguese civil registry
- Clearly specify which matrimonial property regime you’re choosing
- Comply with Portuguese public policy rules
Many people don’t realize that timing is critical. Unlike in some countries, Portuguese prenuptial agreements cannot be modified after marriage. This inflexibility means getting it right the first time is essential.
4. The Three Main Property Regimes in Portugal
When creating a prenuptial agreement in Portugal, you’ll need to choose one of these property regimes:
Separation of Property (Separação de Bens)
This regime keeps all assets – both those acquired before and during the marriage – completely separate. Each spouse maintains sole ownership of their property and is responsible for their own debts.
This is the most popular choice among my entrepreneur clients, as it protects business assets from being divided in a divorce. It also provides clarity for international couples who own assets in different countries.
Community of Property (Comunhão Geral de Bens)
Under this regime almost all assets belonging to either spouse – whether acquired before or during the marriage – become joint property. This is the least common choice among my international clients due to its all-encompassing nature.
Community of Acquired Property (Comunhão de Adquiridos)
This is the default regime in Portugal if no prenuptial agreement exists. Assets acquired during the marriage become joint property, while pre-marriage assets remain separate.
5. International Considerations That Matter
For international couples, there are additional layers of complexity to consider:
- Recognition across borders: Will your Portuguese prenuptial agreement be recognized in your home country?
- Conflicts of law: Which country’s laws will apply if you divorce while living abroad?
- Tax implications: How does your chosen regime affect your tax situation?
6. Common Mistakes to Avoid
Based on my experience, here are the pitfalls to watch out for:
- Waiting until the last minute: I’ve seen couples rush into my office days before their wedding, which leaves little time for proper planning.
- Overlooking asset disclosure: Being transparent about your financial situation is essential for creating an enforceable agreement.
- DIY approach: Using generic templates or trying to adapt foreign agreements without legal advice specific to Portugal can create unenforceable documents.
- Ignoring future assets: Your agreement should address not just what you own now, but what you might acquire in the future.
- Forgetting about debts: A prenuptial agreement should protect you from your partner’s debts, as well as define how assets are handled.
7. The Process
Creating a prenuptial agreement in Portugal follows this process:
- Initial consultation: We discuss your situation, goals and concerns.
- Asset disclosure: Both parties must provide full information about their financial situation.
- Draft agreement: I prepare a document tailored to your specific circumstances.
- Review and revisions: Both parties review the draft with their respective lawyers.
- Notarization: The agreement must be formalized by a notary in Portugal.
- Civil registry: The agreement must be registered with the Portuguese civil registry before your marriage.
The whole process takes 2–4 weeks, so it’s essential to start well before your wedding date.
8. A Smart Investment
Discussing financial matters before marriage may seem unromantic, but I’ve found that it actually helps couples build trust through transparency. A prenuptial agreement isn’t planning for failure – it’s creating clarity that can prevent future misunderstandings.
The cost of a prenuptial agreement in Portugal is typically between €600-€800 plus VAT, depending on complexity. That’s a small price to pay compared to the financial implications of not having one.
9. Get Started
If you’re getting married in Portugal or as a Portuguese resident abroad, starting the conversation about a prenuptial agreement early is key. Marriage is both an emotional and legal commitment, and being informed about how Portuguese law affects your financial future is just good planning.
Remember, once you’re married it’s too late to create a prenuptial agreement in Portugal. The time to act is now, before you say “I do”.
A well drafted prenuptial agreement gives you and your partner the freedom to define your own financial future, rather than leaving it to the default rules of Portuguese law. It’s not about lack of trust – it’s about taking control of your life together on your own terms.
