Brexit Unpaid Invoice Spain — UK Creditor Enforcement Routes

A UK creditor with an unpaid invoice from a Spanish counterparty post-Brexit has lost the simplest enforcement route in the EU and gained a more procedural one. Brussels I Recast no longer applies to UK judgments seeking recognition in Spain, which means the Mareva-style assumption that an English court order would be enforced almost mechanically across the Iberian peninsula is gone. What replaces it, since 1 July 2025, is the Hague 2019 Convention on Recognition and Enforcement of Foreign Judgments. The practical question for a UK exporter, distributor, or services firm with an overdue Spanish invoice is no longer whether enforcement is possible — it is which route is faster: route the dispute through an English court first and then enforce, or skip the English court entirely and file a Spanish proceso monitorio direct.

What changed at Brexit and what changed again on 1 July 2025

Between 31 December 2020 and 30 June 2025, UK creditors operated in a recognition vacuum for Spanish enforcement. Brussels I Recast (Reg 1215/2012) ceased to apply to UK judgments. The Lugano Convention application was blocked by the EU. Hague 2005 covered only exclusive choice-of-court agreements, which most B2B supply contracts do not have. UK judgments could still be enforced in Spain via the residual exequatur regime under LEC Art.41-46, but the procedure was slower, more discretionary, and required a separate Spanish recognition action before any embargo. Hague 2019, in force for the UK from 1 July 2025, restores a treaty-based recognition path for civil and commercial judgments — narrower than Brussels I Recast, with explicit exclusions for insolvency, employment, and consumer matters, but materially faster than common-law exequatur.

For a UK creditor today, the strategic choice is binary. Route one: obtain an English judgment under English procedure (CPR Part 7, default judgment if unopposed), then file a Hague 2019 recognition action in Spain, then enforce. Route two: skip the English court and file a Spanish proceso monitorio directly under LEC Art.812, which produces a Spanish enforceable title in four to eight weeks for uncontested files. Route two avoids the Hague 2019 recognition step entirely and is faster in the overwhelming majority of B2B invoice disputes where the Spanish debtor has no substantive defence.

Why most UK creditors should skip the English court entirely

The English-court-first instinct is doctrinally correct and strategically wrong for B2B invoice debt below GBP 250,000. The reason is procedural arithmetic. An English Part 7 claim with default judgment runs eight to sixteen weeks. Hague 2019 recognition in Spain adds two to four months on the optimistic end. Spanish enforcement then runs another four to eight weeks. The total is six to nine months from claim issue to bank levy. A direct Spanish monitorio runs four to eight weeks for uncontested files, ending in a Spanish enforceable title with no recognition step required. The English-court route is only the right answer when the creditor needs an English judgment for reasons unrelated to Spanish enforcement — for example, a global asset hunt, a parent guarantee triggered by an English judgment, or insurance subrogation that requires English court findings of fact.

The second reason to skip the English court is opposition risk. A Spanish monitorio that the debtor opposes converts to juicio verbal or juicio ordinario in the same court that issued the requerimiento de pago, which is the court of the debtor's Spanish domicile. The debtor cannot use Hague Convention recognition defences because there is no foreign judgment to recognise — the proceeding is Spanish from the start. An English judgment that the debtor opposes at recognition stage in Spain triggers Hague 2019 grounds for refusal review, which adds months and creates argument surface that does not exist in a direct monitorio.

Route comparison — UK creditor against Spanish debtor by total elapsed time

A UK exporter with a EUR 85,000 unpaid Madrid invoice and clean documentary chain reaches a Spanish enforceable title in roughly six weeks via direct monitorio. The same creditor pursuing the English-court-then-Hague route is still waiting for the Spanish recognition court to schedule a hearing at month four. The exception is a debtor who is already insolvent or about to be — in which case neither route reaches the assets in time, and the answer is a concurso claim communication under TRLC RDL 1/2020 plus a hard look at parent guarantees and trade credit insurance.

Should I hire a lawyer or a collection agency for a Spanish debtor?

For a UK creditor with a B2B invoice dispute, a collection agency that operates with in-house Spanish abogados and procuradores is the right starting point, not a UK law firm. The reason is structural. A Spanish monitorio requires filing in Spanish, by Spanish-qualified procurador, at the juzgado of the debtor's Spanish domicile. A UK solicitor cannot file the monitorio directly — they must instruct a Spanish lawyer, which adds a layer of cost and a coordination friction that frequently delays the file by weeks. A collection agency with Spanish litigation capacity files directly, manages the burofax stage, the documentary chain build, the petición inicial, and the post-judgment enforcement — typically on a success-fee basis with no upfront retainer. UK litigation counsel becomes the right answer only when the dispute requires an English judgment for reasons unrelated to Spanish enforcement, or when the matter has escalated into multi-jurisdictional asset tracing where common-law disclosure tools add real value.
