Enforcing Foreign Court Judgments in Spain (2026): Exequatur Procedure, Timelines and Defences Explained

Enforcing foreign judgments Spain is a two-track exercise in 2026: judgments from European Union member states now circulate almost automatically, while judgments from outside the EU still require a formal recognition procedure known as exequatur. This guide sets out who can use each route, which documents a judgment creditor must assemble, how long recognition realistically takes as Spain’s judicial digitalisation reforms take effect, and the limited grounds on which a Spanish court may refuse to give a foreign decision effect. It is written for in-house counsel, foreign law firms and judgment creditors who need practical procedural steps rather than an academic overview.

The overriding message is simple: the legal basis of the judgment determines the route, the timetable and the defences available to the debtor.

Quick checklist, before you file for exequatur

Before starting any application for enforcing foreign judgments Spain, gather the core documentation. A well-prepared file shortens the timetable and reduces the risk of a procedural challenge by the debtor. The following checklist applies whether you are pursuing automatic EU enforcement or a full exequatur application:

• Judgment seat and legal basis. Identify the court and country that issued the judgment and confirm which framework applies, Brussels I Recast, the Hague Choice of Court Convention, a bilateral treaty, or the general regime under Spanish law on international judicial cooperation.
• Certified copy of the judgment. Obtain an authentic or certified copy from the originating court, together with any certificate of finality confirming the decision is enforceable in its country of origin.
• Certified translation. Arrange a sworn Spanish translation of the judgment and supporting documents, prepared by a translator authorised to produce sworn translations for use before Spanish courts.
• Apostille or legalisation. For non-EU judgments, ensure the documents carry an Apostille under the Hague Apostille Convention or, where that does not apply, consular legalisation.
• Power of attorney. Grant a Spanish procurador and lawyer authority to act, executed and legalised for use in Spain.
• Evidence of service. Prove the defendant was properly served in the original proceedings, a central point of attack in refusal applications.
• Enforceability certificate. For EU judgments, obtain the certificate issued by the originating court under Regulation (EU) No 1215/2012.
• Urgent measures. If dissipation of assets is a risk, prepare an application for interim measures (medidas cautelares) in parallel.

Which foreign judgments can be enforced in Spain?

Not every foreign decision travels the same road. Spanish law distinguishes between several categories, and choosing the correct category is the first strategic decision in any matter concerning the recognition of foreign judgments in Spain.

EU judgments. Civil and commercial judgments from EU member states fall under Regulation (EU) No 1215/2012, the Brussels I Recast Regulation. These are recognised without any special procedure and are enforceable in Spain without a declaration of enforceability. In practice, the exequatur step has been abolished for these judgments.

Hague Choice of Court judgments. Where the parties agreed an exclusive choice of court clause and both the originating and enforcing states are bound by the 2005 Hague Convention on Choice of Court Agreements, the Convention governs recognition and enforcement. This is particularly relevant for commercial contracts designating a court outside the EU.

Bilateral treaty judgments. Spain is party to a number of bilateral conventions on recognition and enforcement. Where such a treaty applies, its terms, rather than the general domestic regime, govern the procedure and the grounds for refusal.

Non-convention judgments. Judgments from countries with no applicable EU instrument or treaty, for example, most judgments from the United States, proceed under the general Spanish regime governing exequatur set out in Law 29/2015 on International Legal Cooperation in Civil Matters, combined with the review conditions applied by Spanish courts. This is the classic exequatur route, and it is where the great majority of the procedural detail below is relevant.

Legal bases, Brussels I Recast, Hague Convention, LEC and Law 29/2015

Understanding the legal foundation is essential because it dictates whether exequatur is required at all. The core distinction when enforcing foreign judgments Spain is between judgments that are recognised automatically and those that must first pass through a Spanish court’s recognition filter.

EU judgments (Brussels I Recast), recognition and enforcement mechanics

Under Regulation (EU) No 1215/2012, a judgment given in one member state and enforceable there is enforceable in Spain without any declaration of enforceability being required. There is no separate exequatur to obtain. The creditor applies directly to the competent Spanish enforcement court, producing a copy of the judgment satisfying the conditions necessary to establish its authenticity and the certificate issued by the originating court (under Article 53 of the Regulation) confirming the judgment is enforceable and setting out its key details.

The certificate is the practical linchpin of the process. It confirms the judgment’s enforceability at origin and provides the Spanish court with the information needed to proceed to enforcement, the identity of the parties, the sum due or the obligation ordered, and where relevant the rate of interest and costs. Once the certificate and a certified translation (where required) are lodged, the Spanish court can move to execution measures. The debtor retains the right to apply for refusal of enforcement on the limited grounds preserved by the Regulation, but the burden and the initiative shift to the debtor rather than the creditor.

This is a decisive practical advantage of the EU route: enforcement can begin without waiting for a preliminary recognition ruling.

Hague Choice of Court Convention

The 2005 Hague Convention on Choice of Court Agreements provides a treaty-based route to recognition and enforcement where the parties concluded an exclusive choice of court agreement and both states involved are bound by the Convention. A judgment given by the chosen court must in principle be recognised and enforced in other contracting states, subject to the specific refusal grounds set out in the Convention itself. These include situations where the agreement was null and void, where a party lacked capacity, or where recognition would be manifestly incompatible with public policy.

The Convention’s significance is growing as more states join, and it offers commercial parties a degree of predictability that the general regime cannot match. Where the Convention applies, it displaces the ordinary domestic exequatur analysis, and the Spanish court’s review is confined to the enumerated Convention grounds. For cross-border commercial contracts, drafting an exclusive jurisdiction clause in favour of a contracting state’s courts is therefore a valuable enforcement-planning tool.

Non-EU judgments (Law 29/2015 and LEC exequatur)

Where no EU instrument or treaty applies, recognition proceeds through exequatur under Law 29/2015 on International Legal Cooperation in Civil Matters, connected to the Ley de Enjuiciamiento Civil for the procedural mechanics of enforcement. The Spanish court does not re-hear the merits. Instead it verifies that certain conditions are satisfied: that the foreign court had jurisdiction on grounds compatible with Spanish rules, that the defendant was duly served and able to defend the claim, that the judgment is final and enforceable at origin, that it does not conflict with a Spanish judgment or pending Spanish proceedings, and that recognition would not offend Spanish public policy.

For US judgments, this is the applicable framework. There is no EU instrument or general bilateral treaty covering US civil and commercial judgments, so a judgment creditor must apply for exequatur and demonstrate that the conditions are met. Practically, US judgments are frequently recognised where due process was observed and there is no public policy objection, but each application turns on its facts.

For UK judgments, the position changed with Brexit. UK judgments no longer benefit from the Brussels I Recast regime. Depending on the circumstances, in particular whether an exclusive choice of court agreement engages the Hague Convention, a UK judgment will be recognised either under the Hague Convention or through the general exequatur route under Law 29/2015. Creditors seeking to enforce a UK judgment in Spain should analyse at the outset whether the underlying contract contained an exclusive jurisdiction clause, because that single fact can determine whether the faster Convention route is available.

Exequatur procedure, step-by-step for enforcing foreign judgments Spain

For any judgment requiring exequatur, the procedure follows a structured sequence. The steps below describe the practical path for enforcing foreign judgments Spain outside the automatic EU regime.

1. Determine the competent court. Exequatur applications are filed before the Juzgado de Primera Instancia of the party against whom recognition is sought, usually the debtor’s domicile, or the place where the judgment is to take effect. Where enforcement targets assets, the location of those assets is relevant to identifying the correct forum.
2. Assemble the documentary file. Lodge the authentic or certified copy of the foreign judgment, an Apostille or consular legalisation, a sworn Spanish translation, proof that the judgment is final and enforceable at origin, and evidence that the defendant was properly served.
3. Appoint representation. Grant power of attorney to a Spanish lawyer and procurador. The power must be legalised for use in Spain.
4. File the application. Submit the exequatur petition, increasingly through the electronic filing systems used across Spanish courts as the judiciary digitalises.
5. Service and response. The party against whom recognition is sought and the public prosecutor (Ministerio Fiscal) are given the opportunity to be heard, with opposition possible on the permitted grounds.
6. Court decision. The court issues a reasoned order (auto) granting or refusing recognition. If granted, the judgment becomes enforceable in Spain and the creditor can proceed to execution.
7. Execution. With recognition in place, the creditor applies for enforcement measures, attachment of bank accounts, seizure of property, garnishment of receivables, under the ordinary rules of the Ley de Enjuiciamiento Civil.

Two documentary points cause the most delay. The first is translation quality: a translation that does not accurately render the operative part of the judgment invites challenge. The second is proof of service: creditors should obtain, at the time of the original proceedings, clear documentary evidence that the defendant was served, because reconstructing that record years later is difficult. Preparing these elements before filing is the single most effective way to compress the timetable.

Timelines and realistic expectations (2026)

Realistic planning depends on the route. When enforcing foreign judgments Spain through the EU regime, the absence of a preliminary recognition step means creditors can move to enforcement measures relatively quickly, with straightforward matters concluding the recognition-and-execution phase in a matter of weeks to a few months, subject to any debtor challenge.

Exequatur for non-EU judgments takes considerably longer. Timeframes vary widely by court and complexity, and can commonly run from several months to well over a year from filing to a final recognition order, driven by service on the debtor, any opposition, translation and authentication issues, and local court caseloads. Contested applications, particularly those raising public policy or jurisdiction arguments, sit at the upper end of that range or beyond.

The judicial reforms and the wider digitalisation programme promoted by the Ministerio de Justicia are gradually improving these timetables. Electronic filing, digital case management and the digital submission of documents and evidence reduce the friction that previously came from paper-based procedures. The practical effect is expected to be modestly faster processing in courts that have fully adopted the new systems, though the benefit varies significantly between jurisdictions and creditors should plan conservatively rather than assume a uniform acceleration. Where speed matters, the answer is rarely to rely on faster court processing and almost always to secure the asset position early through interim measures.

Grounds for refusal and common defences

Spanish courts do not re-examine the merits of a foreign judgment. Refusal is confined to a defined set of grounds, and understanding them is essential both for creditors anticipating opposition and for debtors mounting a defence. The principal refusal grounds in exequatur applications are:

• Lack of jurisdiction of the original court. Where the foreign court assumed jurisdiction on a basis incompatible with Spanish rules, including Spain’s exclusive jurisdiction grounds, recognition may be refused.
• Denial of due process. If the defendant was not duly served in sufficient time to arrange a defence, or was otherwise deprived of a fair opportunity to be heard, recognition can be denied. This is among the most frequently invoked defences.
• Incompatibility with Spanish public policy (orden público). Recognition is refused where it would be manifestly contrary to fundamental principles of the Spanish legal order.
• Irreconcilable judgments. A foreign judgment that conflicts with a judgment given in Spain between the same parties, or with an earlier foreign judgment entitled to recognition, will not be recognised.
• Procedural defects and finality. A judgment that is not final and enforceable at origin, or that suffers from serious procedural irregularity, is vulnerable to challenge.
• Res judicata and pending Spanish proceedings. Prior Spanish decisions and ongoing Spanish litigation on the same matter can bar recognition.

Tactically, creditors should pre-empt the two most common attacks, due process and jurisdiction, by building a clean documentary record from the outset. Debtors, for their part, should focus resources on the grounds with the best factual support rather than raising every objection, since Spanish courts interpret the refusal grounds restrictively and are unsympathetic to attempts to relitigate the merits under the guise of a procedural defence.

Public policy (orden público), narrow application

Public policy is the ground most often argued and least often successful. Spanish courts apply orden público narrowly, reserving it for cases where recognition would offend genuinely fundamental principles of the domestic legal order, not mere differences between Spanish and foreign substantive law. A judgment is not contrary to public policy simply because a Spanish court might have decided the case differently or applied a different measure of damages.

The narrow construction has clear tactical consequences. A debtor who intends to rely on public policy needs a specific, principled objection, for example, a violation of fundamental procedural fairness or an outcome incompatible with core constitutional protections, rather than a general complaint about the foreign result. For creditors, the restrictive approach is reassuring: even judgments that look unusual by Spanish standards are frequently recognised. Where a public policy argument does have traction, a negotiated settlement may deliver a faster and more certain recovery than a contested defence with an uncertain outcome.

Practical enforcement steps after recognition (execution)

Recognition is the gateway; execution is where recovery actually happens. Once a judgment is recognised, or, for EU judgments, once the certificate is lodged, the creditor deploys the enforcement tools of the Ley de Enjuiciamiento Civil. The principal measures are attachment of bank accounts, seizure and sale of movable and immovable property, and garnishment of sums owed to the debtor by third parties such as customers or tenants.

Where the debtor owns real estate, the recognised judgment can support enforcement against property recorded in the Land Registry (Registro de la Propiedad), enabling the creditor to secure and ultimately realise the asset. Enforcement against third parties, for instance banks holding the debtor’s funds, is a routine and effective route, provided the creditor can identify the relevant institutions. Asset investigation therefore often runs in parallel with the recognition process, so that execution can proceed promptly once recognition is obtained.

Insolvency changes the picture significantly. If the debtor enters an insolvency process, individual enforcement is generally stayed and the creditor must pursue recovery within the collective proceeding governed by the Ley Concursal (Texto Refundido de la Ley Concursal). This makes timing critical: a creditor who secures interim measures and moves promptly to execution stands a far better chance of recovery than one who waits, particularly where the debtor’s solvency is deteriorating.

Costs, security and contingency planning

Costs vary with the route and the level of opposition. EU enforcement, involving no preliminary recognition step, is generally the most economical. Exequatur for non-EU judgments involves lawyer and procurador fees, sworn translation and authentication costs, and court-related expenses, with contested matters costing considerably more than uncontested ones. Creditors should also budget for asset investigation and for the execution phase itself.

Security may be relevant in two respects. First, an application for interim measures generally requires the applicant to provide security (caución) to cover potential damage to the debtor if the measure later proves unjustified. Second, a debtor who opposes recognition or appeals a recognition order may prolong the process, and creditors should plan for the possibility of appeals extending the timetable. Building a realistic contingency into any recovery plan, both on cost and on time to enforcement against actual assets, avoids unpleasant surprises and supports informed decisions about whether to litigate or settle.

Comparison table, EU vs Hague vs Non-EU exequatur

The table below summarises the three principal routes for enforcing foreign judgments Spain, allowing creditors to identify the applicable framework and its practical consequences at a glance.

When to seek interim measures in Spain (medidas cautelares)

Recognition takes time, and a debtor with notice of an incoming enforcement may move or dissipate assets. Interim measures, medidas cautelares, allow a creditor to secure the position before recognition concludes. The available measures include preventive attachment (embargo preventivo) of bank accounts and specific assets and, in appropriate cases, orders supporting asset disclosure.

To obtain interim measures a creditor generally needs to show a good arguable case on the underlying claim (fumus boni iuris), a real risk that delay will frustrate enforcement (periculum in mora), and a willingness to provide security. Where the risk of dissipation is acute, urgent applications can be made, including without prior hearing of the debtor in cases of urgency. For any creditor pursuing enforcement of a significant judgment, considering interim measures at the very start, not after recognition, is often the difference between a paper victory and actual recovery.

Practical checklist for counsel instructing Spanish lawyers

Foreign counsel can materially accelerate matters by providing Spanish lawyers with a complete, well-organised file at the outset. When instructing local counsel on enforcing foreign judgments Spain, provide the following and ask the questions below:

• The judgment and finality certificate. A certified copy of the judgment plus documentary proof that it is final and enforceable at origin.
• Service records. Full evidence of how and when the defendant was served in the original proceedings.
• EU certificate (if applicable). The Article 53 certificate for Brussels I Recast judgments.
• Asset information. Any known bank accounts, real estate, receivables or other assets in Spain.
• Contract documents. The underlying contract, especially any exclusive jurisdiction clause relevant to the Hague route.

Key questions to ask Spanish counsel include: which route applies and why; whether interim measures should be sought immediately; the realistic timetable and cost estimate for the specific court; the debtor’s likely defences; and the strategy for moving from recognition to execution against identified assets.

Key takeaways and next steps

• The legal basis determines everything: EU judgments enforce almost automatically, while non-EU judgments require exequatur under Law 29/2015.
• Prepare documents early, certified copies, sworn translations, Apostille and proof of service prevent the most common delays.
• Plan for a lengthy timetable on contested non-EU exequatur, and use interim measures to protect assets in the meantime.
• Refusal grounds are narrow and public policy is applied restrictively; Spanish courts do not re-hear the merits.
• Digitalisation reforms are improving timetables modestly, but conservative planning and early asset protection remain the safest strategy.

Conclusion

Enforcing foreign judgments Spain in 2026 rewards early preparation and an accurate reading of the applicable legal basis. EU creditors enjoy a fast, near-automatic route; non-EU creditors face a longer exequatur process under Law 29/2015 but can succeed where due process was observed and no genuine public policy objection arises. The most successful strategies combine a clean documentary file, prompt interim measures to protect assets, and realistic planning for the recognition and execution phases. For a case-specific assessment of the best route and timetable, professional guidance on Spanish enforcement strategy is strongly recommended.
