Prenuptial Agreement (Capitulaciones Matrimoniales) Spain

A Prenuptial Agreement (Capitulaciones Matrimoniales) Spain is a formal notarial instrument executed by two persons intending to marry — or by married spouses — through which they establish, modify, or replace the matrimonial property regime (régimen económico matrimonial) that will govern the economic relationship between them during marriage and upon dissolution, as authorised by Código Civil Article 1325. The Código Civil, enacted by Real Decreto de 24 de julio de 1889 and substantially reformed by Ley 11/1981 de 13 de mayo and Ley 15/2005 de 8 de julio, establishes the framework for matrimonial property regimes in Spain and permits spouses full freedom to determine their property arrangements within the limits of the law, public order (orden público), and good customs (buenas costumbres).

Spain operates a system of legal default regimes that apply in the absence of capitulaciones matrimoniales. In most of Spain, the default regime is the sociedad de gananciales (community of acquisitions) governed by Código Civil Articles 1344–1410, under which property and income acquired by either spouse during the marriage forms part of the communal estate (bienes gananciales) and is divided equally upon dissolution. However, in the Comunidades Autónomas with their own civil law systems (Derechos Forales), different default regimes apply: in Catalunya, the default regime since Codi Civil de Catalunya (Llei 25/2010) is separació de béns (separation of property); in the Islas Baleares, the default regime under Compilació de Dret Civil Balear is also separation of property; in Aragón, the default under Código del Derecho Foral de Aragón (Decreto Legislativo 1/2011) is consorcio conyugal; in Navarra, the default is conquistas under Ley 1/1973 (Fuero Nuevo de Navarra); and in Euskadi, the default under Ley 5/2015 del Derecho Civil Vasco is comunicación de bienes.

Capitulaciones Matrimoniales in Spain may establish any of three principal regimes: (1) separación de bienes (separation of property) under Código Civil Articles 1435–1444, under which each spouse retains full ownership and management of their own property before and during marriage; (2) participación (participation regime) under Articles 1411–1434, under which each spouse manages their own property during marriage but, upon dissolution, participates in the gains obtained by the other; or (3) a modified sociedad de gananciales with specific provisions derogating from the statutory default — for example, excluding certain assets from the ganancial estate, modifying the rules for administration, or providing for unequal division upon dissolution.

Capitulaciones Matrimoniales must be executed in escritura pública (public deed) before a Notario inscribed in the Consejo General del Notariado, as required by Código Civil Article 1327. Without notarial execution, the capitulaciones are void. The escritura must then be notified to the Registro Civil where the marriage is or will be recorded (Registro Civil Central or local Juzgado de Paz) under Article 1333 CC, to be effective against third parties. Where the capitulaciones affect real property, the deed must also be presented to the Registro de la Propiedad of the relevant jurisdiction for annotation against the affected properties.

The capitulaciones matrimoniales may be executed before marriage — in which case they take effect from the date of the marriage ceremony (Article 1326 CC) — or during the marriage, in which case they take effect from the date of execution (Article 1331 CC). Modification of the régimen económico matrimonial during marriage requires agreement of both spouses, a new escritura pública, and compliance with the notification and registration requirements of Articles 1333 and 1334 CC. Third parties who contracted with the spouses in good faith reliance on the prior regime are protected under Article 1317 CC.

Capitulaciones Matrimoniales Spain are needed whenever two persons intending to marry, or already married, wish to regulate their matrimonial property regime in a manner that differs from the legal default applicable in their Comunidad Autónoma of residence, or wish to modify or confirm an existing regime with specific provisions tailored to their circumstances.

Capitulaciones are needed when the couple wishes to adopt the separación de bienes regime — the most commonly chosen alternative regime in Spain — to confirm that each spouse retains full ownership and management of their own assets and that no new ganancial estate is created. This is particularly important for spouses who each own significant personal or business assets, for entrepreneurs (autónomos) or company shareholders who wish to protect their business interest from claims arising from the other spouse's debts, and for professionals facing business liability risk.

The agreement is needed when a foreign national marrying a Spanish citizen wishes to establish a clear property regime — given that Reglamento (UE) 2016/1103 sobre regímenes económicos matrimoniales, applicable in Spain since 29 January 2019, determines the law applicable to the matrimonial property regime of international couples based on the spouses' first common habitual residence, their common nationality, or an express choice of law agreed in writing.

Capitulaciones are needed when the couple wishes to specify the treatment of pre-marital property (bienes privativos) and to exclude it expressly from any future ganancial claim — particularly relevant for inherited property (bienes heredados), property received by donation (donación), or property acquired before the marriage at a time when one spouse had significant assets.

The agreement is required when a married couple wishes to change their existing régimen económico matrimonial — for example, converting from sociedad de gananciales to separación de bienes — which requires a new escritura pública of capitulaciones and compliance with Código Civil Article 1333 notification obligations to protect the amendment against third-party creditors.

Capitulaciones matrimoniales are also needed when the couple wishes to make donations between spouses (donaciones por razón de matrimonio) under Código Civil Articles 1336–1343, or to establish specific provisions for the liquidation of the matrimonial property regime upon divorce, separation, or death — complementing the regime provisions with agreed liquidation procedures that reduce the risk of future disputes before the Juzgado de Primera Instancia Family Court.

Under Spanish law, the Código Civil governs marriage (Article 66), divorce (Article 81), custody (Article 92), and maintenance (Article 142). The Ley Orgánica 1/1996 (LOPJM) protects minors. The Registro Civil records births, marriages, and deaths. The Ley 15/2015 de Jurisdicción Voluntaria governs non-contentious proceedings. The Ley Orgánica 1/1982 protects fundamental rights including image and privacy.

Valid Capitulaciones Matrimoniales Spain under Código Civil Articles 1315–1444 must contain the following essential elements to be effective and enforceable against both parties and third parties.

Identification of Parties: Full legal names, DNI/NIE numbers, dates and places of birth, civil status (estado civil), and domicile of both parties. Where either party is represented by a legal representative (through a power of attorney — poder notarial — under Código Civil Article 1280), the representative's identity and the scope of the power must be identified. Both parties must have full legal capacity (capacidad de obrar plena) to execute capitulaciones — minors who are legally emancipated under Articles 323–324 CC may execute capitulaciones with the consent of their legal representative.

Declaration of Current Matrimonial Status: Whether the parties are about to marry (indicando la fecha prevista de la boda) or are already married — if married, the date and place of the civil ceremony and the Registro Civil where the marriage is recorded must be stated, to enable registration of the capitulaciones against the marriage record under Article 1333 CC.

Chosen Matrimonial Property Regime: Clear statement of the matrimonial property regime agreed — separación de bienes (Código Civil Articles 1435–1444), participación (Articles 1411–1434), modified sociedad de gananciales, or the applicable Foral regime where relevant. The key provisions of the chosen regime must be set out with sufficient detail — particularly any derogations from the statutory default provisions.

Inventory of Pre-Marital Assets (Optional but Recommended): A detailed inventory (inventario) of each spouse's existing assets — real property with cadastral reference and Registro de la Propiedad details, bank accounts, investment portfolios, business interests (participaciones sociales or acciones), vehicles, and significant personal property — to establish the private character (carácter privativo) of these assets from the date of the capitulaciones. This inventory is particularly important under a separación de bienes regime to prevent future disputes about the origin of specific assets.

Treatment of Family Home (Vivienda Habitual): Specific provisions addressing ownership and occupation rights in the vivienda habitual (family home) — particularly important for properties held jointly, subject to a mortgage, or contributed by one spouse — and the treatment of the vivienda upon separation, divorce, or death, taking into account the protections afforded by Código Civil Article 96 (assignment of family home use upon separation or divorce) and Article 1320 (prohibition on disposal of the family home without the other spouse's consent).

Debt and Liability Provisions: Agreement on which debts are private (privativos) and which are shared, particularly relevant for business owners and professionals — under sociedad de gananciales, ganancial assets may be liable for debts contracted by one spouse in the exercise of their ordinary household authority under Article 1365 CC, so the capitulaciones should clearly allocate liability to prevent unintended exposure.

Donations Between Spouses (Donaciones por Razón de Matrimonio): Any donations agreed in contemplation of marriage under Código Civil Articles 1336–1343 — subject to the limits of Ley del Impuesto sobre Sucesiones y Donaciones (Ley 29/1987) and the applicable Comunidad Autónoma donation tax rules, which vary significantly — must be formally executed in the escritura pública.

Notarial Execution and Registration: Confirmation that the escritura pública will be executed before a Notario, stamped by the Colegio Notarial, and submitted to the Registro Civil for annotation against the marriage record under Article 1333 CC, and to any relevant Registro de la Propiedad where real property is affected. Failure to register the capitulaciones in the Registro Civil means they are not effective against third parties who in good faith contracted with the spouses under the assumption of the legal default regime — Código Civil Article 1317.
