My husband and I have been house-hunting recently near Barcelona, mainly for investment purposes. The process has been a mix of excitement and stress, but we got a bit confused when a key question came up: whose name should be on the title deed? Just one of us, or both? I’m sure many couples have faced the same dilemma, so I’ve compiled some information I gathered from lawyers and real estate agents, hoping it can help you all.

Choosing the Form of Ownership
In Spain, there are two main forms of property ownership for married couples, and this choice is crucial as it directly affects future asset division and tax matters. In simple terms, these are the “community of property” and “separation of property” regimes.
Community of Property (Régimen de Gananciales): This is the default marital property regime in Spain. Under this system, property acquired after marriage is considered joint property, owned 50/50 by both spouses, regardless of whose name is on the title. The advantage is its simplicity, aligning with the common family concept of ’what’s mine is yours.' However, the disadvantage is that if one spouse incurs debt, the other may also be held jointly liable.
Separation of Property (Separación de Bienes): Under this regime, ownership is very clear. For a jointly purchased property, ownership is divided according to the contribution ratio. If the property is purchased solely by one spouse, even after marriage, it belongs exclusively to that person, which is relevant for the division of marital property. The drawback of this method is that it requires prior planning, but the benefit is that it effectively isolates each spouse’s personal debts from the other.
Comparison of Ownership Forms
To make it clearer, here is a simple table illustrating the differences:
| Feature | Community of Property (Gananciales) | Separation of Property (Separación de Bienes) |
| Default Regime | Yes | No |
| Property Ownership | Default joint ownership, 50% each | Owned by contribution or agreed ratio |
| Debt Liability | Joint liability | Each spouse bears their own personal debt |
| Asset Independence | Lower | Higher |
Tax and Legal Liabilities
Regardless of which regime you choose, the taxes due at the time of purchase are the same. However, the situation changes in the future, for instance, when it comes to inheritance or gifts. For example, under the Gananciales regime, if one spouse passes away, the surviving spouse automatically owns 50% of the property and only needs to handle the inheritance of the remaining 50%. In contrast, under Separación de Bienes, the inheritance process applies to the deceased’s entire share of the property. Furthermore, if you consider selling the property in the future, capital gains tax will also be calculated based on each spouse’s ownership share, which is a key part of transferring property between spouses. Therefore, this is not just a question of ‘whose name goes on the deed’ but a long-term financial planning issue. It is highly recommended to consult with a professional lawyer or tax advisor to make a decision based on your family’s specific circumstances.
