Recognition and Enforcement of Foreign Titles in Spain

In an increasingly global legal environment, disputes, contracts, and court decisions often cross national borders. When a judgment or other enforceable document is issued abroad, it may need a recognition step (to be accepted as legally effective in Spain) and/or an enforcement step (to allow coercive execution against assets in Spain). Spain applies a structured system that prioritises EU rules, then international treaties, and finally Spanish domestic law (especially Law 29/2015 and the Civil Procedure Act).

Recognition and enforcement in practice

What recognition means

Recognition means Spain accepts the foreign decision as valid and capable of producing legal effects (for example, res judicata and declaratory effects). Under Spanish law, recognition can be sought as a main issue through an exequátur procedure or raised incidentally within another Spanish proceeding, with effects limited to that proceeding.

What enforcement means

Enforcement (execution) means compulsory measures to obtain compliance, such as attachments, garnishments, or auctions. Once a title is enforceable in Spain, execution follows the rules of Spain’s Ley de Enjuiciamiento Civil (LEC).

The legal framework for foreign titles in Spain

The importance of choosing the correct route

Spain applies a layered framework. The applicable route depends on the origin of the title and the subject matter. EU instruments apply first where relevant, followed by treaties, and then Law 29/2015.

EU titles and simplified enforcement

For many EU civil and commercial judgments, the key instrument is Regulation (EU) 1215/2012 (Brussels I bis). It provides that an enforceable judgment from one EU Member State is enforceable in another without a declaration of enforceability (no exequátur).

Other subject areas have separate EU regimes, including family and parental responsibility (Regulation (EU) 2019/1111) and maintenance (Regulation (EC) 4/2009).

Non-EU titles and the exequátur route

For judgments from non-EU states, Spain checks whether an international treaty applies. If not, the default route is Law 29/2015, which typically requires exequátur to recognise and, where necessary, enforce.

Enforcing EU judgments in Spain

Enforcement without exequátur under Brussels I bis

Under Brussels I bis, a judgment that is enforceable in the Member State of origin is enforceable in Spain without any declaration of enforceability.

The documents usually required

To enforce an EU judgment under Brussels I bis, the enforcing party typically produces:

• A copy of the judgment meeting authenticity conditions
• The certificate issued under Article 53 (Annex I)

Service requirements before enforcement measures

When enforcing in Spain, the Article 53 certificate must be served on the debtor before the first enforcement measure, and it must be accompanied by the judgment if the judgment has not yet been served.

Translations and practical filing strategy

Brussels I bis allows Spanish authorities to require translations where necessary to proceed, and the defendant may request translations in certain situations. In practice, filing a sworn Spanish translation of the operative part of the judgment and the Annex I certificate can reduce delays.

How to enforce a EU judgment in Spain

Confirm the applicable EU instrument

If the judgment concerns a civil or commercial matter and is not within an excluded area, enforcement will usually follow Brussels I bis.

Obtain the judgment enforcement documents

You normally need:

• An authentic copy of the judgment
• The Brussels I bis Article 53 certificate (Annex I) issued by the court

Prepare translations where necessary

If the Spanish court cannot proceed without understanding the documents, it may require translations. Preparing them in advance often avoids procedural friction.

Start enforcement proceedings in Spain

Enforcement is pursued through a Spanish execution proceeding under the LEC, requesting concrete measures such as bank attachment, wage garnishment, or property embargo, and providing any asset information available.

Comply with the service timing rules

Before the first enforcement measure, ensure service of the Article 53 certificate (and judgment where required).

Resistance and refusal grounds

Brussels I bis limits refusal to specific grounds such as public policy, serious defence or service issues in default cases, and irreconcilability with another judgment. Once Spanish execution is opened, the debtor may also raise certain LEC opposition grounds depending on the procedural stage.

Recognition and enforcement of non-EU judgments in Spain

Checking for an applicable international treaty

Before applying Law 29/2015, determine whether a treaty governs recognition and enforcement for the country of origin. Potentially relevant instruments include the Hague Judgments Convention, the Hague Choice of Court Convention, and the Lugano Convention, depending on the parties, the state of origin, and the subject matter. For arbitral awards, the New York Convention is typically relevant.

Exequátur under Law 29/2015

Law 29/2015 provides that exequátur is the procedure used to obtain recognition as a principal matter and, where appropriate, authorise enforcement. The law allows the exequátur request and the enforcement request to be combined in the same filing, but execution will not proceed until exequátur is granted.

Competent Spanish court

As a general rule, exequátur is filed with the Juzgado de Primera Instancia (currently still so named under Law 29/2015, although under the judicial reorganisation introduced by Organic Law 1/2025 these courts will be replaced by the Tribunales de Instancia, Sección Civil) of the respondent’s domicile, or subsidiarily the place of enforcement or where the judgment must produce its effects.

Representation by lawyer and procurador

The exequátur procedure begins by demanda filed by any person with a legitimate interest and requires procurador (mandatory court representative under Spanish civil procedure) representation and letrado (lawyer) assistance.

Required documents and common sources of delay

The demanda (application for exequatur) must be accompanied by:

• The original or authentic copy of the foreign judgment, duly legalised or apostilled
• Proof of proper service of the initiating document in default cases
• Proof that the judgment is final and, where relevant, enforceable in the state of origin
• Translations required under Spanish procedural rules

Protective measures while exequátur is pending

The applicant may request medidas cautelares under the LEC to preserve effectiveness during the exequátur process.

Opposition period, decision, and appeals

After service, the respondent has thirty business days to oppose and may file documents challenging authenticity, service, finality, or enforceability. The court decides by auto, and the Ministerio Fiscal (Public Prosecutor) intervenes. The auto is appealable and, in certain cases, extraordinary appeals may be available under the LEC framework.

Refusal grounds and limits of review

Spanish courts do not re-litigate the merits. Recognition or enforcement can be refused on limited grounds, including public policy, serious violations of defense rights, conflict with Spanish exclusive jurisdiction, irreconcilability with a Spanish judgment or an earlier recognizable foreign judgment, and lis pendens in Spain.

Enforcement after exequátur

Once exequátur is granted, enforcement proceeds under the LEC, including Spanish rules on expiry of enforcement actions, and Spain allows partial enforcement where appropriate.

Conclusion

Spain offers a reliable framework for cross-border enforcement, but selecting the correct route is decisive. EU civil and commercial judgments are generally enforceable directly under Brussels I bis, while non-EU judgments typically require exequátur under Law 29/2015 unless a treaty applies, and enforcement then follows the LEC execution system.
