UK SME with Spanish debtor: post-Brexit collection

A UK SME holding an unpaid invoice from a Spanish counterparty since Brexit faces a different procedural map than a German or French SME — Brussels I Recast no longer applies, Hague 2019 only entered force in the United Kingdom on 1 July 2025, and the cross-border enforcement step that EU peers take for granted has become a separate procedure with its own timeline and cost. For SME-sized invoices in the EUR 5,000 to EUR 100,000 range, the maths often points away from the High Court route and toward filing the monitorio directly in Spain. This page covers the route prioritisation for UK SMEs after Brexit, the documentary work required, and how the Spanish statutory framework supports the file.

What changed for UK SMEs collecting from Spain after Brexit

From 1 January 2021, the Brussels I Recast regulation stopped applying to UK creditors. A UK High Court or County Court judgment lost its automatic enforceability across the EU, including Spain. For four and a half years, UK creditors operating against Spanish debtors with a UK judgment in hand had to fall back on Spanish exequatur procedures under the Spanish Ley de Cooperación Jurídica Internacional (Ley 29/2015), which is a manageable route but adds three to nine months and a separate set of court fees. The Hague 2019 Convention entered force for the United Kingdom on 1 July 2025, providing a more uniform recognition framework, but the framework still requires a Spanish court application — it is not automatic.

For SME-sized invoices, the threshold question is whether to litigate in the United Kingdom at all. A UK High Court or County Court money judgment costs court fees, often involves solicitors, and produces a judgment that still needs Spanish recognition before any embargo on a Spanish bank account is possible. For invoice sizes under approximately EUR 50,000, the route that bypasses the UK litigation step entirely and files the Spanish monitorio directly typically delivers a faster recovery and lower total cost. The monitorio is open to non-Spanish creditors on identical terms — no UK judgment is required, the Spanish court issues a directly enforceable Spanish title, and the embargo runs against the debtor's Spanish assets without further recognition.

When a UK judgment route still makes sense — invoice size and jurisdiction clauses

There are cases where the UK litigation step adds value. Where the contract has an exclusive English jurisdiction clause and the debtor would credibly argue the Spanish court lacks competence, the UK proceedings produce the only enforceable judgment. Where the invoice value is large enough that the Spanish recognition step is a small marginal cost relative to the principal, the maths shifts in favour of UK litigation followed by Hague 2019 recognition in Spain. Companion analysis on the broader Brexit enforcement framework covers the trade-offs in more depth, and the procedural mechanics of enforcing an English judgment in Spain under Hague 2019 are addressed separately for cases where a UK judgment is already in hand.

For SMEs whose contracts contain non-exclusive jurisdiction clauses, generic governing-law-but-no-jurisdiction-clause language, or no contract at all beyond a purchase order, the Spanish monitorio is procedurally available and tends to dominate the cost-benefit. The Spanish court treats the foreign creditor identically to a Spanish creditor on monitorio standing — what matters is the documentary chain proving liquidated, due, demandable monetary debt under LEC Art.812, not the creditor's nationality.

Route comparison — UK SME creditor against Spanish debtor

For UK SMEs with smaller invoice values, faster route prioritisation typically means filing the monitorio direct ahead of any UK judgment exercise. The Spanish framework provides the same Ley 3/2004 ECB+8pp interest, the same EUR 40 per-invoice fixed compensation, and the same direct enforceability into Spanish bank accounts that an EU creditor would receive. The Brexit-related procedural friction sits on the UK-judgment-recognition side, and routing around it is usually the SME-rational choice. Larger UK creditors with high-value claims, exclusive English jurisdiction clauses, or specific commercial reasons to obtain a UK judgment first should run the full Hague 2019 framework — the route exists, it works, but it is not the SME default.

Should a UK SME hire a UK solicitor and pursue a UK judgment first, or file the monitorio directly in Spain?

For invoice values below approximately EUR 50,000 and in the absence of an exclusive English jurisdiction clause, file the monitorio directly in Spain. The Spanish procedure is open to UK SMEs on identical terms to Spanish creditors, runs in four to eight weeks uncontested, produces a directly enforceable Spanish title, and avoids the UK-judgment-then-recognition double step that Brexit imposed. UK solicitor involvement is rarely required for the Spanish file itself; the Spanish abogado and procurador handle the procedural lodgement. Where the invoice value justifies it, or where a UK judgment is already in hand, the Hague 2019 recognition route in Spain is the correct path and produces a workable timeline once the UK judgment exists. The threshold question is invoice size relative to combined route cost, not legal preference.
