Having recently moved to Spain, my partner and I are looking to buy our first home together. A very practical question came up during our search: if we buy a house, who does it legally belong to? Should the deed be in one person’s name, or both? And what happens if our relationship changes in the future, concerning the property jurisdiction? I’m sure many of you have similar questions. I’ve done some research into Spanish law and wanted to share my findings. I also welcome any knowledgeable friends to add to or correct my understanding.
Understanding Spain’s Marital Property Regimes
First, it’s crucial to understand that Spain’s marital property system is not uniform across the country; different autonomous communities have different regulations. Most regions, like Madrid and Andalusia, default to the community of goods regime (régimen de gananciales). Simply put, any money earned or assets purchased after marriage belong to both spouses jointly. However, some regions, such as Catalonia and the Balearic Islands, default to the separation of property regime (separación de bienes), meaning each spouse manages their own money and owns what they purchase individually. Of course, regardless of the default system, couples can choose their preferred property regime through a public deed (capitulaciones matrimoniales) before or after the wedding.

Who Owns the Property? Two Key Factors
Setting aside complex legal jargon, I’ve summarized that property ownership hinges on two main factors: the time of purchase and the source of funds. The outcome varies completely depending on the situation.
Property Purchased Before Marriage: If a property was bought by one person with their own money before the marriage, it is unequivocally their separate property. Even if the other partner moves in after marriage and helps pay off part of the mortgage, the fundamental ownership of the property does not change. Of course, the contributions made towards the mortgage can be claimed as compensation if the relationship ends, but this does not alter the property’s ownership.
Property Purchased After Marriage: This depends on which property regime applies to you. Under the most common ‘community of goods’ regime, a house bought after marriage is considered joint marital property, regardless of whether the property deed is in one name or both, as long as the money used for the purchase comes from post-marital income. If you separate later, it will be divided equally. However, if the funds for the purchase were from one spouse’s pre-marital savings, an inheritance, or a gift, and the source can be clearly proven, the property might still be recognized by the Land Registry as separate property.
To make it clearer, I’ve created a simple table to illustrate property ownership under the default ‘community of goods’ regime in different scenarios:
| Purchase Scenario | Source of Funds | Property Ownership |
| Before marriage, purchased by Partner A | Partner A’s personal savings | Partner A’s separate property |
| After marriage, deed in Partner A’s name | Joint marital income | Joint marital property |
| After marriage, deed in both A & B’s names | One partner’s pre-marital funds | Divided by contribution ratio or agreement |
| After marriage, purchased by Partner A | Gift from parents to Partner A | Partner A’s separate property |
When buying property in Spain, ownership is a serious matter. Although talking about money can be uncomfortable, understanding the process at the Land Registry and planning ahead is a responsible way to protect both parties. This is especially true in regions that default to the ‘separation of property’ regime or when there’s a significant financial disparity between partners. It’s always better to discuss these things openly than to face disputes later on. How did you all handle this when buying your homes? Feel free to share your experiences!
