My partner and I have been having a headache with house hunting lately. After finally finding a place we love, we got stuck on the issue of whose name to put on the title deed. After asking around and consulting our mortgage advisor at the bank, we finally got it all straight. I’m sharing our findings here, hoping to help others with the same question.
In Spain, when a married couple buys a property, the deed can be in one person’s name or in both names. These two options have significant legal, tax, and especially future implications for property division or inheritance. Many people assume that as long as you’re married, it doesn’t matter whose name is on the deed, but this is not entirely true in Spain!
The Key Factor: Your Marital Property Regime
In Spain, the core factor determining property ownership isn’t whose name is on the deed, but the marital property regime you chose when you got married. By default, in most regions of Spain, the “community property regime” (régimen de gananciales) automatically applies.
- Community Property (Régimen de Gananciales): Any income earned or property purchased by either spouse after marriage is considered joint marital property. Under this system, even if the title deed is in only one person’s name, the property is presumed to be owned 50/50 by the couple. However, if the funds used for the purchase were one spouse’s pre-marital assets and the source of funds for the Spanish property ownership can be proven at the notary’s office, it can be considered separate property.
- Separation of Property (Separación de Bienes): This is the default regime in regions like Catalonia, or it can be chosen by a couple through a prenuptial agreement. As the name suggests, each spouse manages their own assets after marriage, and any property purchased belongs solely to the buyer. If the title deed is in one person’s name, the property belongs entirely to that person.

Pros and Cons: One Name vs. Both Names on the Deed
With an understanding of these regimes, the pros and cons of each approach become much clearer. I’ve made a simple table to help illustrate:
| Scenario Analysis | Pros | Cons / Risks |
| Only One Name on the Deed | In theory, only one person needs to sign during the process, which might save some minor hassle. | Very high risk! Especially under the separation of property regime, the non-titled spouse has no protection. Even under community property, the non-titled spouse’s signature is still required for any future sale or mortgage, making the process more complicated. In the event of a divorce or death, proving ownership also requires extra legal steps. |
| Both Names on the Deed | Offers the clearest rights and most comprehensive protection. The legal ownership is clear, with each partner holding a 50% share. Any future sale, inheritance, or division will follow legal procedures, avoiding potential disputes and complications. |
Regardless of your marital property regime, the safest and most recommended approach is to put both of your names on the deed! This was the primary advice we received from every lawyer and bank manager. For those who are not married but are in a registered domestic partnership (Pareja de Hecho), it is even more crucial to have both names on the deed, as there is no default marital property regime governing your assets. In this case, the names on the title deed are the sole proof of ownership. I hope this information is helpful, and I welcome anyone with experience to add to the discussion!
