Spanish Customer Filed Concurso — Foreign Creditor Rights

A foreign supplier learning that a Spanish customer has filed for concurso de acreedores has roughly thirty days from the publication of the auto de declaración to file proof of claim, and somewhere between zero and fifteen percent recovery to play for if they file as an ordinary creditor and twice that if they secure privileged ranking. The TRLC RDL 1/2020, which consolidated Ley 22/2003 in 2020 and was reformed again by Ley 16/2022, governs the procedure. The window is short, the ranking rules are unforgiving, and creditors who file late or wrongly classified take the full discount of the procedure. This page covers what the foreign creditor must do in the first thirty days, how the ranking actually works, and where the leverage points sit.

What concurso means for the unpaid invoice

The auto de declaración del concurso is published in the BOE and in the Registro Público Concursal. The Spanish debtor remains in possession of its assets in the common case, supervised by an administrador concursal appointed by the Juzgado de lo Mercantil. From that moment, individual enforcement actions are stayed under TRLC Art.142, the monitorio file the creditor was about to launch is no longer available, and existing embargo preventivo orders are vacated. The only path to recovery becomes the proof of claim — comunicación de créditos — that every creditor must file within thirty days of the BOE publication.

For an overseas creditor, the practical consequence is that the procedural posture flips. Outside concurso, the creditor sets the pace: monitorio, embargo preventivo, enforcement. Inside concurso, the administrador concursal sets the pace, and the creditor's leverage is reduced to the quality of the proof of claim filed and the ranking it secures. The window to make this filing well is the first month. Files lodged on day forty-five or sixty are accepted, but ranked as subordinated under TRLC Art.281, which in practice means recovery of zero in most procedures.

Where the foreign creditor's claim ranks — and why ranking decides recovery

TRLC Articles 269 to 281 set the ranking. Privileged credits — those secured by mortgage, pledge, or by statutory operation such as wage and tax claims of recent vintage — are paid first, in full, against the assets to which the privilege attaches. Ordinary credits, which is where most unpaid commercial invoices sit, are paid pari passu from what remains after privileged claims. Subordinated credits — late-filed, related-party, contractually subordinated, or interest accrued post-declaration — are paid only if the ordinary class is fully satisfied, which in Spanish practice is exceedingly rare.

A foreign supplier with a routine commercial invoice and no in-rem security ranks as ordinary. The way to upgrade is rare and fact-specific: a retention-of-title clause properly notified before the auto date, a documented setoff right, or a credit secured by aval on a third party. Where none of these apply, the file should still claim ordinary ranking precisely and document the EUR 40 fixed compensation per invoice plus interest under Ley 3/2004 as part of the principal — accrued interest after the auto becomes subordinated, but pre-auto interest sits inside the ordinary credit position.

Recovery realities — what concurso actually pays out

The Ley 16/2022 reform introduced the plan de reestructuración with the cross-class cramdown mechanism transposed from EU Directive 2019/1023. A foreign creditor in the ordinary class can find their claim rewritten by majority vote of other classes, including pre-bankruptcy if the company files for the new pre-pack route. The procedural defence is to participate in the vote actively, not passively — the silence of an unrepresented foreign creditor often functions as acquiescence to the proposed discount.

My Spanish customer just filed concurso. What do I file and by when?

File a comunicación de créditos with the appointed administrador concursal within thirty calendar days of the auto de declaración being published in the BOE. The filing must identify the creditor, the principal sum claimed, the date and origin of the credit, the supporting documentation (invoices, contract, delivery proofs, burofax acknowledgements), the statutory interest calculated under Ley 3/2004 up to the auto date, and the ranking claimed — almost always ordinary for an unsecured commercial invoice. File by certified email to the administrador's listed address with PDF attachments of the documentary chain. Late filings are demoted to subordinated under TRLC Art.281 and recover effectively nothing. After filing, monitor the lista de acreedores published roughly two months in, and use the fifteen-day impugnación window to challenge any wrong classification of your credit.
