Property Separation or Community Property? The Ultimate Guide
Getting married and don't know which economic regime to choose? We explain in simple terms the differences between property separation and community property...

Congratulations on your engagement! This is a moment full of excitement, dreams, and plans for the future. While you're deciding on the perfect venue, your dream dress, and the guest list, there's an important conversation that's often left until the end: the matrimonial economic regime. The economic regime is independent of whether you choose civil or religious wedding, but must be legally formalized.
I know it can sound a bit intimidating and not at all romantic, but believe me, understanding what property separation and community property are is an act of love and responsibility. It's like building the foundations of your house: you want them to be solid so your life project together is strong and stable.
This post is designed to be that chat with a friend who's already been through this. I'll take you by the hand so you understand, without technicalities or complications, what each option means, what their advantages are, and how you can choose the one that best suits your life. Let's do this!
What Is Property Separation?
Imagine that each of you has your own piggy bank. In the property separation regime, each spouse maintains ownership, administration, and enjoyment of their own property, both what they had before marriage and what they acquire afterward.
In short: what's yours is yours and what's mine is mine.
This means that each person owns their salary, investments, properties, and, very importantly, also their debts. If one of you buys a car, that car is theirs. If they take out a personal loan, that debt is solely theirs.
Of course, this doesn't mean you can't have things in common. You can buy a house together, open a joint bank account, or invest together. In those cases, you'll be owners of those assets in the proportion you decide (normally 50%), as you would with any other person.
The key is that a common patrimony isn't automatically created by the fact of being married.
And What Is Community Property?
Community property is the regime that applies by default in most of Spain (except in Catalonia, the Balearic Islands, and the Valencian Community, where it's property separation). Think of it as if, when you get married, you create a third common piggy bank, in addition to the two individual ones.
In this system, three patrimonies coexist:
- Private patrimony of one spouse: These are the assets they had before marriage or those they receive afterward through inheritance or donation.
- Private patrimony of the other spouse: Same, but for the other member of the couple.
- Community patrimony: This is the "common piggy bank." Everything you earn or obtain during the marriage thanks to your work, income, or interest from your assets (even private ones) goes here.
For example, both salaries, profits from a business you set up, or rent from an apartment (even if the apartment was the private property of just one) are community property. Everything bought with that common money will also belong to both.
The Key Differences: Face to Face
To make it even clearer, let's put the two systems face to face.
| Aspect | Property Separation | Community Property |
|---|---|---|
| Ownership | Each person owns their assets and earnings. | A common patrimony is created with earnings from the marriage. Previous assets, inheritances, and donations are private. |
| Management | Each person manages their own with total freedom. | For important assets (like selling a community property house) consent from both is needed. |
| Debts | Each person is responsible for their debts with their own patrimony. | Debts incurred by one to meet family needs can affect community property assets. |
| Divorce | Each person keeps what's theirs. Only jointly purchased assets are divided. | The community is liquidated: common debts are paid and the remaining community patrimony is divided 50%. |
| Inheritance | The widowed spouse inherits according to what's established in the will and the law regarding the deceased's assets. | The widower receives their 50% of community property and, additionally, their inheritance rights over the deceased's half. |
Advantages and Disadvantages: Which One Is for Me?
There's no single answer. The best option depends on your personal, professional, and financial situation. Let's analyze the pros and cons of each to help you reflect.
Property Separation
Advantages:
- Independence and autonomy: You have total freedom to manage your patrimony without needing to ask permission.
- Protection against debts: If your partner has a business or profession with financial risk (for example, they're self-employed), your personal patrimony will be safe from their possible debts.
- Simplicity in case of divorce: Dissolution is much simpler, as there's no large common patrimony to liquidate. It avoids many conflicts.
Disadvantages:
- Lack of protection for the spouse with lower income: If one of you decides to stop working to care for children or the home, they'll find themselves at an economic disadvantage in case of divorce, as they won't have generated their own patrimony during those years. The law provides for economic compensation in these cases, but it can be a complicated process and fair compensation isn't always achieved.
Community Property
Advantages:
- Protection and solidarity: It's the most supportive system. It recognizes the value of both contributions to the marriage, both economic and home and family care. Both build a future together.
- Fosters a common project: Psychologically, it reinforces the idea that all effort goes into a common pot, strengthening the concept of team.
- Tax benefits: On some occasions, such as donations between spouses, it can have tax advantages.
Disadvantages:
- Complexity in management: For important acts regarding community property assets, you always need the other's signature.
- Complexity in case of divorce: The liquidation of community property can be a long, costly, and emotionally exhausting process, especially if there's no agreement on the value of assets.
The Risk of Debts in Community Property: A Key Point
This is one of the issues that worries most, and rightly so. In community property, if one of the spouses incurs a debt to cover the normal needs of the family (such as paying for children's school, buying food, or household expenses), community property assets are first responsible for that debt.
Practical example: María and Javier are married under community property. Javier is self-employed and his business is going badly. He takes out a bank loan of €30,000 to try to salvage it, but he doesn't succeed and can't pay it. The bank could seize community property assets to collect the debt, for example, money from a joint account or even the family car they bought together. María's private patrimony (like an apartment she inherited from her parents) would, in principle, be protected.
However, if it's proven that the debt benefited the entire family, responsibility could extend. That's why it's a point that requires a lot of attention if one of you has a risky economic activity.
How to Choose the Economic Regime for Your Marriage
Now that you have all the information, sit down with your partner and talk with total sincerity. Discussing the economic regime before the wedding helps have transparent financial conversations from the start. Here's a step-by-step guide to make the decision:
- Analyze your starting point: Do you have very different patrimonies? Does one already have a business? Are there previous debts?
- Project your future: Are you going to start a business? Is one of you planning to stop working to care for children? Do you have different investment plans?
- Talk about your life philosophy: Are you more of a "what's mine is yours" or do you prefer to maintain economic independence? Neither option is better than the other, it's just a matter of what makes you feel more comfortable.
It's a good idea to ask yourselves these questions:
- If one of you is a business owner or self-employed, property separation may be the safest option to protect the family patrimony.
- If your incomes are very unequal or one plans not to work outside the home, community property may be fairer and more protective for that person.
- If you both have stable careers and similar incomes and value independence, property separation may fit perfectly.
The Legal Process: How Is It Formalized?
The formalization of your economic regime is done through a document called prenuptial agreement.
- What are they? They're a contract signed before a notary where you specify the economic regime you want for your marriage (property separation, community property, or another).
- When can they be done? They can be signed before the wedding (they come into effect when you get married) or after the wedding, at any time. In civil weddings, you can declare the economic regime directly in the marriage act.
- If you do nothing: As we've mentioned, in most of Spain community property will apply by default. In Catalonia, the Balearic Islands, and the Valencian Community, it will be property separation.
- The process is simple: You just need to make an appointment at a notary's office with your IDs. The notary will advise you and draft the document according to your will. Then, it's registered in the Civil Registry so it has effects against third parties. Wedding witnesses don't sign prenuptial agreements, but they do sign the marriage certificate where the chosen regime is recorded.
Big sister advice: Don't see prenuptial agreements as a sign of distrust. On the contrary, it's a sign of maturity, communication, and that you care about leaving things clear to protect each other.
