Régimen Económico Matrimonial (Marital Property Regime)

Understanding the marital property regime is critical for expats in Spain, particularly when buying property, making a will, or planning for inheritance. The regime determines whether property bought during the marriage belongs to both spouses jointly or to the purchasing spouse alone. It also affects what happens on death — the surviving spouse’s rights depend heavily on which regime applies. Many expats are unaware that getting married in Spain (or being habitually resident here) may change their property regime from what they expected.

Important: Spanish succession follows two distinct paths depending on whether the deceased left a valid will (testate) or not (intestate). The intestate path requires a Declaration of Intestate Heirs (Declaración de Herederos Abintestato) — a step not needed when a will exists. Learn more about the succession process →

The Three Main Regimes

• Sociedad de Gananciales (Community of Property): The default in most of Spain (except Catalonia, Balearic Islands, Valencia, Aragon, Navarra, Basque Country). All assets acquired during the marriage belong to both spouses equally, regardless of who earned the money. Pre-marital assets and inheritances remain separate.
• Separación de Bienes (Separation of Property): The default in Catalonia, Balearic Islands, and Valencia. Each spouse owns what they earn or acquire. There is no shared marital estate. This is similar to the English common-law position.
• Régimen de Participación (Participation Regime): Rarely used. During the marriage, each spouse manages their own assets independently. On dissolution, the spouse who gained less is entitled to half the difference between the two estates’ growth.

Key Facts About Marital Property Regimes

• The default regime depends on the spouses’ vecindad civil (civil domicile within Spain) or applicable national law
• Couples can choose a different regime through capitulaciones matrimoniales (prenuptial or postnuptial agreement) before a notary
• Under gananciales, BOTH spouses must consent to sell community property
• The regime affects inheritance: under gananciales, half the community estate belongs to the surviving spouse outright (it is not part of the inheritance)
• International couples should check which country’s law governs their regime — EU Regulation 2016/1103 provides rules
• Changing regime after marriage is possible via notarial deed (capitulaciones matrimoniales)
• The Property Registry records which regime applies to each property
