Matrimonial Agreements in Spain: What Are Capitulaciones?

🇪🇸 Read the original in Spanish

When two people decide to get married in Spain, the excitement of the moment often eclipses one of the most important financial decisions of their lives: defining how their money, debts, and assets will be managed from the moment they say "I do." In the Spanish legal system, love and finances are closely linked, and failing to make an active decision in this regard means letting the law decide for you. Matrimonial agreements, known as capitulaciones matrimoniales, are precisely the legal tool designed for spouses to take control of their financial destiny, avoiding future conflicts and protecting each partner's individual assets.

What are capitulaciones matrimoniales and what are they for?

The capitulaciones matrimoniales (matrimonial agreements / prenuptial or postnuptial agreements) are a contract or public deed through which future spouses, or those who are already married, stipulate, modify, or replace the economic regime of their marriage. This document not only regulates how assets acquired during the union will be managed, but can also contain inheritance provisions, agreements in anticipation of a future breakdown, or the allocation of specific assets.

Its primary function is to provide legal certainty to the couple. By signing this agreement, you prevent the automatic application of the default economic marital regime imposed by law (the supplementary legal regime), allowing you to adapt the family finances to the actual needs of the spouses—especially when there are personal businesses, pre-existing family assets, or significant differences in each partner's income.

The regulatory framework in the Spanish Civil Code

Family law in Spain is governed by a fundamental principle: the free autonomy of the will of the parties, provided that the laws and equality between spouses are not violated. The reference regulatory framework is found in the *Code Civil (Código Civil, Book IV, Title III)*.

• The right to enter into agreements: *Article 1315 of the Código Civil** establishes that "the economic regime of the marriage shall be that which the spouses stipulate in the capitulaciones matrimoniales, with no other limitations than those established in this Code"*.
• Limits on freedom of contract: Article 1255 (on freedom of contract) and, specifically, *Article 1328 of the Código Civil** declare null and void any stipulation in the capitulaciones* that is contrary to the law or good customs, or that limits the equal rights corresponding to each spouse.
• Timing of the agreement: According to *Article 1326 of the Código Civil**, capitulaciones* can be executed before or after the marriage is celebrated. If they are executed before, the marriage must take place within a maximum period of 1 year for the document to be valid.
• Solemn form: *Article 1280.3º of the Código Civil** requires capitulaciones to be executed in a public deed before a Notario (Notary Public) for their legal validity (an ad solemnitatem* requirement).

Gender perspective and family protection

It is essential to note that Spanish family law has evolved to protect the most vulnerable members of the couple. Law 15/2005, of July 8, which modifies the Código Civil and the Ley de Enjuiciamiento Civil (Civil Procedure Act) regarding separation and divorce, streamlined the breakdown procedures (the so-called "express divorce") and reinforced the importance of agreements in anticipation of a breakdown that can be included in the capitulaciones.

Furthermore, Organic Law 1/2004, of December 28, on Integrated Protection Measures against Gender Violence, operates as an impassable limit in drafting these agreements. Any clause in the capitulaciones matrimoniales that attempts to limit the rights to assistance, maintenance, or custody in a context of gender violence, or that violates the dignity and safety of the woman and minors, will be radically null and void and will have no legal effect.

The three economic marital regimes in Spain

To understand what capitulaciones are for, it is essential to know the three main options offered by Spanish legislation:

1. Régimen de Sociedad de Gananciales (Community of Property Regime)

This is the default regime in most of the common Spanish territory (under the Código Civil). Under this system, any earnings or benefits obtained indistinctly by either spouse during the marriage become common to both. Upon dissolution (due to divorce or death), the common assets are split in half (50% for each). Assets acquired before the marriage, or those received afterwards by inheritance or donation, remain the private property (bienes privativos) of each spouse.

2. Régimen de Separación de Bienes (Separation of Property Regime)

This is the default regime in Catalonia and the Balearic Islands, and the most requested via capitulaciones in the rest of Spain. Under this system, each spouse retains the ownership, administration, and free disposal of all their assets, both those owned before the marriage and those acquired during it. Debts contracted by one spouse are their sole responsibility, protecting the assets of the other.

3. Régimen de Participación (Participation Regime)

This is a hybrid and rarely used regime. During the marriage, it functions like a separation of property (each manages their own assets), but at the time of dissolution, the spouse who has obtained a smaller increase in assets has the right to participate in the gains obtained by the other during the time the regime was active (generally 50% of the difference).

Practical examples with real figures

To understand the financial impact of choosing one regime over another through capitulaciones, let us analyze two everyday scenarios:

Example 1: Protection against debts and entrepreneurship

• The situation: Carlos and Sofía are getting married in Madrid. Carlos is going to open a dental clinic, for which he requests a loan of €80,000. Sofía works as an employee and owns a home valued at €220,000.
• Without capitulaciones matrimoniales (Gananciales): If they do not sign capitulaciones, they marry under the community property regime. If Carlos's business fails and he cannot pay the €80,000 loan, creditors can seize the common assets of the marriage, including the bank accounts where Sofía's salary is deposited. Even though Sofía's home is private property (purchased before marriage), the income she generates during the marriage is considered community property and is at risk.
• With capitulaciones (Separación de bienes): Carlos and Sofía sign capitulaciones before the wedding for a cost of €70 before a notary, opting for the separation of property. If Carlos's business fails, the €80,000 debt is exclusively his. Sofía's assets, her salary, and her home remain 100% protected from the clinic's creditors.

Example 2: Compensation for housework

• The situation: María and Javier marry under the separation of property regime via capitulaciones. They agree that María will reduce her working hours to care for their two common children, giving up income worth €1,200 per month for 6 years. Javier, thanks to María's dedication to the home, is promoted in his company, and his personal savings increase by €90,000.
• The application of the law: *Article 1438 of the Código Civil*** establishes that work for the home shall be computed as a contribution to the marriage expenses and shall give the right to obtain economic compensation when the separation of property regime is terminated.
• The resolution: Upon divorcing, María can legally claim (or agree in the regulatory agreement) a compensatory indemnity based on the minimum wage or the cost of hiring a third party during those 6 years. If they had agreed on a specific clause in their capitulaciones regulating this compensation (for example, setting an indemnity of €15,000 for each year of exclusive dedication), they would have avoided a long and costly judicial divorce process.

Step-by-step practical steps to execute capitulaciones

If you have decided that capitulaciones matrimoniales are the best option for your future, these are the steps you must follow in Spain:

1. Agree on the regime and terms: Both spouses (or future spouses) must agree on the clauses to be included. It is highly recommended to seek the advice of a family lawyer to draft the proposal.
2. *Choose a Notary's Office (Notaría): You can go to any Notario* in Spain. You must provide the personal details of the appearing parties and the draft agreement, if any.
3. Provide the required documentation:

• Valid National Identity Document (DNI), NIE (Número de Identidad de Extranjero), or Passport of both parties.
• If you are already married: The Libro de Familia (Family Book) or a Literal Marriage Certificate issued by the Registro Civil (Civil Registry) (no older than 3 months).
• If there are specific assets you wish to inventory: property deeds, notas simples (property registry extracts), or bank certificates.

1. Signing of the Public Deed: Both spouses must physically go to the notary's office to sign the deed of capitulaciones matrimoniales before the Notario, who will attest to the act and verify that there are no abusive or illegal clauses.
2. Registration in the Civil Registry: For the capitulaciones to have effect against third parties (for example, banks or creditors), it is mandatory to register them in the Registro Civil where the marriage is (or will be) registered. If they are executed before the wedding, the Notario usually sends the deed electronically to the Civil Registry after the wedding takes place.
3. Registration in other registries (optional but recommended): If the capitulaciones include the transfer of real estate or affect company shares, they must also be registered in the Registro de la Propiedad (Property Registry) or the Registro Mercantil (Mercantile Registry), respectively.

Deadlines, costs, and key figures

To plan this procedure properly, keep the following timeframes and financial figures in mind:

• 12 months: This is the maximum validity period for capitulaciones executed before marriage. If you do not marry within 1 year from signing before the notary, the document will become void (*Article 1326 of the Código Civil***).
• From €60 to €150: This is the average cost of notary fees (fees regulated by law) for a standard deed of capitulaciones matrimoniales without a complex inventory of assets.
• 30 days: This is the usual timeframe for the Registro Civil to process and register the deed of capitulaciones after its submission.
• €0 (Tax exemption): Executing capitulaciones matrimoniales that are limited to changing the economic regime (for example, from community property to separation of property) is subject to but exempt from the Impuesto sobre Transmisiones Patrimoniales y Actos Jurídicos Documentados (ITP-AJD / Transfer Tax and Stamp Duty), provided that no asset allocations are made that result in taxable excess allocations.

Mistakes you should avoid

• Not registering the capitulaciones in the Civil Registry: If you sign the separation of property before a notary but do not register it in the Registro Civil, the agreement will be valid between you, but it will not be opposable to third parties. This means that if your spouse incurs a debt with a bank, the bank can target your assets as if you were still under community property, as the change of regime is not publicly recorded.
• Letting the one-year deadline pass after signing prenuptially: If you execute capitulaciones before the wedding and, for any reason, you delay the wedding for more than 12 months, the document will automatically expire, and you will have to go back to the notary and pay the fees again.
• Including null or illegal clauses: Do not attempt to include agreements that violate the equality of the spouses, limit parental authority (patria potestad) over children, or waive the duty of maintenance. Clauses such as "in the event of divorce, the mother waives custody of the children" or "neither spouse may work outside the home" are radically null and void.
• *Ignoring regional law (Derecho Foral) specialities: If you reside in Catalonia, Aragon, the Balearic Islands, the Basque Country, Navarre, or Galicia, remember that there are specific regional civil laws (derecho foral) that regulate economic regimes differently from the common Código Civil. Failing to seek advice on the civil regional status (vecindad civil*) of the spouses can lead to unpleasant surprises.

Frequently Asked Questions (FAQ)

Can capitulaciones matrimoniales be changed multiple times?

Yes. *Article 1325 of the Código Civil** allows the economic marital regime to be modified as many times as the spouses wish during the marriage. The only requirement is that both agree, appear before a notary to execute a new deed, and register it in the Registro Civil*. However, modifying the economic marital regime will under no circumstances harm rights already acquired by third parties (creditors) prior to said modification.

What happens if one of the spouses is a foreigner?

Spain has a high rate of international marriages. If one or both spouses are foreigners, Regulation (EU) 2016/1103 on matrimonial property regimes applies. Through capitulaciones, the couple can expressly choose which law will govern their assets: the law of the State of the habitual residence of either spouse or the law of the State of nationality of either spouse at the time of signing. If they do not choose, the law of their first common habitual residence after marriage will apply.

Is it mandatory to make capitulaciones matrimoniales to get married?

No, not at all. If you decide not to execute capitulaciones, the marriage will be governed by the economic regime established by default by the applicable civil law. In most of Spanish territory (under the common Código Civil), this regime is the sociedad de gananciales. In Catalonia and the Balearic Islands, the default regime is separación de bienes.

Can community assets be liquidated in the same deed of capitulaciones?

Yes. If you are already married under community property and decide to change to separation of property, you can use the same notary deed to carry out the *liquidation of the sociedad de gananciales. This involves making an inventory of the common assets and debts and distributing them at 50%* between both. This procedure is more complex, and its notary and tax costs will depend on the value of the assets being allocated.

Summary

• The capitulaciones matrimoniales are a contract in a public deed before a Notario that defines the economic regime of the marriage.
• They can be executed before or after the wedding; if before, the marriage must be celebrated within a maximum period of 1 year.
• They primarily serve to choose the separación de bienes, protecting individual assets against the other spouse's debts and facilitating business management.
• They have a very accessible notary cost, usually ranging between €60 and €150 for simple deeds.
• For them to have full validity and effect against third parties (such as banks or creditors), it is mandatory to register them in the Civil Registry.
• They allow the inclusion of agreements in anticipation of a future breakdown, provided they respect the equality of the spouses and the best interests of minors.
