Each year, thousands of couples formed by a Spanish citizen and a foreign national decide to take the step of formalising their relationship through marriage in Spain. This act, which represents an emotional milestone of great relevance, opens the door to a complex web of legal procedures that not only regulate the marital bond but also determine the administrative and residency status of the foreign spouse. Understanding the requirements of the Civil Code, passing the rigorous marriage file process to avoid suspicion of a "marriage of convenience", and processing the subsequent residence authorisation are crucial steps that require precision, patience, and a rigorous knowledge of Spanish regulations.

Marriage between a Spanish citizen and a foreigner (commonly referred to as a mixed marriage) is fully recognised and protected by the Spanish legal system. The fundamental premise is that the right to marry is a constitutional right that is not lost due to the foreign citizen being in an irregular administrative situation.

The Civil Code as the Fundamental Pillar

The substantive rules governing marriage capacity, consent, and the forms of celebration are detailed in the *Spanish Código Civil (Civil Code)*.

Law 15/2005 and the Streamlining of Divorce

Law 15/2005, of July 8, which modifies the Código Civil and the Ley de Enjuiciamiento Civil (Civil Procedure Act) regarding separation and divorce, brought about a radical change by eliminating the legal grounds required to request a separation or divorce. This is highly relevant for mixed marriages, as it stream-lines procedures in the event of a breakdown and redefines compensatory pensions, making it easier for foreign citizens who divorce in Spain to clearly understand their rights and obligations without needing to prove "fault".

Organic Law 1/2004 on Integrated Protection Measures against Gender Violence

Organic Law 1/2004, of December 28, on Integrated Protection Measures against Gender Violence, has a direct impact on the immigration status of foreign women married to Spanish citizens. In the event of suffering gender violence by their Spanish spouse, the law and the Reglamento de Extranjería (Immigration Regulations) protect the victim so that she does not lose her right to reside in Spain. Even if the marital bond or cohabitation is broken, the foreign woman has the right to apply for an independent residence and work permit under exceptional circumstances from the moment a protection order is issued or a report from the Public Prosecutor's Office exists.

Step 1: The Preliminary Marriage File (Mandatory Procedure)

Before the wedding can take place, it is mandatory to process a *preliminary expediente matrimonial (marriage file)*. The main objective of this procedure is to verify that both parties have the legal capacity to marry and that consent is not flawed (i.e., that it is not a marriage of convenience or "for papers").

Since the reform of the Ley del Registro Civil (Civil Registry Law), this file can be processed either at the "Registro Civil" of the municipality where either of the parties resides, or before a Notary. The notary route has drastically reduced waiting times.

Required Documentation for the Spanish Citizen:

  1. *Valid Documento Nacional de Identidad (DNI)* (original and copy).
  2. Literal certificate of birth, issued by the Registro Civil of their place of birth, no older than 3 months.
  3. **Certificado de empadronamiento (town-hall registration certificate) covering the last two years, issued by the corresponding Town Hall (expires after 3 months**).
  4. **Fe de vida y estado (certificate of life and marital status)* (proving single status), issued by the Registro Civil*.
  5. If divorced: Literal certificate of the previous marriage with the marginal note of divorce.

Required Documentation for the Foreign Citizen:

  1. Full valid passport (original and copy of all pages, including blank ones). If they hold a Tarjeta de Identidad de Extranjero (TIE - Foreigner Identity Card), this must also be provided.
  2. Birth certificate, duly legalised or apostilled (Hague Apostille) and, if not in Spanish, translated by a sworn translator authorised by the Ministry of Foreign Affairs, European Union and Cooperation.
  3. Certificate of single status or capacity to marry, issued by their country's consulate in Spain or by the authorities of their country of origin (also legalised and translated).
  4. **Certificado de empadronamiento (town-hall registration certificate)** covering the last two years. If they have resided abroad, they must provide a certificate issued by the competent authority of their country or by the corresponding consulate.
  5. If divorced: Divorce decree duly legalised, apostilled, and translated. If the divorce took place abroad and the previous spouse was Spanish, it may be necessary to first undergo the Exequátur (recognition of a foreign judgment in Spain) process.

The Private Interview (The Suitability Interview)

This is the step most feared by couples. The officer processing the file will summon the future spouses to a separate interview (audiencia reservada). The objective is to verify the authenticity of the relationship. Personal questions about each other's lives will be asked, such as:

If the officer considers that the answers are consistent and that a genuine emotional relationship exists, they will issue an approval decree (auto de aprobación) for the file, authorising the celebration of the marriage.

Step 2: Celebration and Registration of the Marriage

Once the file is approved, the couple has a period of 1 year to celebrate the marriage before their chosen authority (Judge, Mayor, Notary, etc.).

After the celebration, the marriage must be registered in the Spanish "Registro Civil".

Step 3: Residency Procedures for the Foreign Spouse

Once the marriage is registered in the Spanish Registro Civil, the foreign spouse acquires the right to reside and work in Spain on equal terms with Spanish citizens, under the protection of European Union regulations.

The Arraigo Familiar (Family Ties - General Regime)

Following recent reforms to the Reglamento de Extranjería (Real Decreto 629/2022), the pathway for the spouse of a Spanish citizen has preferentially become the **Arraigo Familiar (Family Ties)**, framed under exceptional circumstances.

This permit grants the foreign spouse:

Economic Requirements and Means of Subsistence

Unlike the old Tarjeta de Familiar de Ciudadano de la Unión (Union Citizen Family Member Card) (which required proving that the Spanish citizen had an employment contract or sufficient funds equivalent to 100% of the IPREM), the Arraigo Familiar for spouses of Spanish citizens is more flexible, although the Oficina de Extranjería (Immigration Office) will always assess that they do not become a burden on the state's social assistance.

Deadlines, Fees, and Key Figures

To plan this process successfully, it is essential to know the approximate waiting times and financial costs associated with each stage of the procedure:

Practical Examples of Costs and Feasibility

To realistically illustrate how these processes unfold, we analyse two common scenarios of couples initiating these procedures in Spain.

Example 1: Notarial procedure with a spouse in an irregular situation

Example 2: Marriage in the Registro Civil with a prior divorce

Mistakes You Must Avoid

Making a mistake during the document preparation phase or during the interview can result in the denial of the marriage or the archiving of the residency file, forcing the couple to start the entire process from scratch.

Frequently Asked Questions (FAQ)

Can a foreigner in an irregular situation marry a Spanish citizen in Spain?

Yes, absolutely. The right to marry is a fundamental human right enshrined in the Spanish Constitution. The irregular administrative situation of the foreign citizen is not a legal impediment to contracting marriage. The Registro Civil office or the Notary cannot report the irregular status of the applicant nor deny the file for this reason alone, provided it is proven that consent is genuine and not fraudulent.

How long does it take for the foreign spouse to be able to work legally?

The foreign spouse will be able to work legally in Spain once they are granted the residence permit through Arraigo Familiar. Although the right stems from the marriage itself, in order to be effectively registered with the Seguridad Social (Social Security) by an employer, a favorable resolution from the Extranjería office and the assignment of the definitive NIE number are required. This process usually takes between 2 and 4 months from the submission of the residency application.

What happens to the foreigner's residency if the marriage ends in divorce?

If the marriage is dissolved by divorce before 3 years have passed since the wedding, the foreign spouse could lose their Union citizen family member card or Arraigo Familiar residency, unless they meet certain stability requirements (such as having been married for at least three years, of which at least one year was spent in Spain, or having custody of shared children). Nevertheless, the foreigner always has the option to modify their residence permit to a general residence and work regime if they hold a valid employment contract.

Is it necessary to hire a lawyer to get married and obtain residency?

It is not mandatory by law, but it is highly recommended. Preparing foreign documentation, legalising prior divorce decrees, sworn translations, and preparing for the private interview are complex procedures. A formal error can delay the process for months or lead to a denial that negatively affects the immigration status of the foreign spouse.
