The Civil Procedure Act is the procedural code on which all civil and commercial litigation in Spain rests. Every time a company claims an unpaid debt, a landlord initiates an eviction, a shareholder challenges a company resolution or a consumer seeks repayment of an overcharge, the channel is that established by Ley 1/2000, of 7 January. Understanding its structure and mechanisms is not just a matter for lawyers: it is a competitive advantage for any company that litigates or wants to litigate with knowledge of the rules.
This guide analyses the LEC as it stands in 2026: its structure, the stages of a typical proceeding, the articles with the greatest practical impact, and the questions most frequently raised by companies and individuals.
What is the Civil Procedure Act and what is its origin
Ley 1/2000, of 7 January, de Enjuiciamiento Civil (LEC) came into force on 8 January 2001, replacing the previous Civil Procedure Act of 1881, which had survived for one hundred and twenty years. The new statute radically modernised Spanish civil procedure: it replaced the written and dispersed instruction model with a system of oral proceedings and concentration, strengthened equality of arms between the parties, and aligned Spanish procedural law with European standards.
The LEC has subsidiary application to all other jurisdictions: wherever the labour procedure act (LRJS), the administrative (LJCA) or criminal procedure (LECrim) do not provide otherwise, the LEC applies. This makes it, in practice, the backbone of the Spanish procedural system.
Structure of the LEC: four books
The LEC is organised in four books with distinct content:
Book I: General provisions (arts. 1-280). Governs jurisdiction and competence (objective, territorial and functional), procedural capacity of the parties, representation and defence by solicitor and barrister, procedural acts (form, deadlines, communications), evidence in general and specific means of evidence (party interrogation, witnesses, expert opinion, documents, judicial inspection).
Book II: Declaratory proceedings (arts. 281-516). This is the practical core of the LEC. It governs the ordinary trial and the oral trial, with their respective stages of claim, defence, pre-trial hearing and trial. It also includes second-instance procedure and extraordinary appeals (procedural infringement and cassation).
Book III: Forced execution and interim measures (arts. 517-747). Governs enforcement titles, issuing of enforcement orders, attachments and forced realisation of assets, as well as the regime for civil interim measures.
Book IV: Special proceedings (arts. 748-827). Contains proceedings on capacity, parentage, marriage, minors; payment order proceedings; bill of exchange proceedings; and division of estates.
The ordinary trial: the main route for civil disputes
The ordinary trial is the standard procedure for disputes above €6,000 or involving certain matters specifically determined by law. It has four main stages:
The claim (art. 399 LEC)
Every ordinary trial begins with a written claim. Art. 399 LEC sets out its content: identification of the parties, ordered and numbered statement of facts, legal grounds and specific prayer for relief. The claim must be accompanied by the documents on which the claimant relies (contracts, invoices, prior demands) and the solicitor’s powers. A defective claim may be rectified, but substantive defects — lack of standing, limitation — are not cured merely by admission.
The defence (arts. 404-408 LEC)
The defendant has 20 working days from service to file a defence. In the defence, procedural objections (exceptions) and substantive defences may be raised, the facts denied, documents produced and a counterclaim brought (art. 406 LEC). If the counterclaim meets the connectivity requirements, the claimant must also respond to it within 20 days. A defendant who does not file a defence in time is declared in default, but may enter an appearance at any subsequent point.
The pre-trial hearing (arts. 414-430 LEC)
The pre-trial hearing is one of the most characteristic features of the LEC 1/2000. It takes place before the judge, with the parties or their representatives required to attend. It serves three purposes: first, to explore the possibility of agreement or settlement; second, to examine and resolve any procedural objections that might prevent continuation (art. 416 LEC: lis pendens, lack of capacity, improper procedure, formal defects in the claim); third, to identify precisely the disputed facts and to admit the relevant evidence. Evidence not proposed at the pre-trial hearing cannot, as a general rule, be adduced at trial.
The trial and judgment
The trial is the oral hearing at which the admitted means of evidence are adduced: party interrogation, witnesses, experts, documents and judicial inspection. After the trial, the judge delivers judgment within the statutory period of 20 days. The ordinary trial judgment may be appealed before the Provincial Court.
Civil procedural appeals: the chain of challenge
Appeal (arts. 455-467 LEC)
The appeal is the ordinary remedy against first-instance judgments. It is lodged with the court that delivered the judgment but resolved by the Provincial Court (or the Court of First Instance if the judgment comes from a magistrates’ court). The time limit for lodging is 20 working days from notification. The appellant must set out in writing the alleged errors in the judgment (art. 458 LEC). The Provincial Court may review both the facts and the law applied.
Extraordinary appeal on procedural infringement (art. 469 LEC)
This exceptional remedy only succeeds on the four specific grounds in art. 469 LEC: infringement of rules on jurisdiction and competence, infringement of procedural rules governing the judgment, infringement of rules on procedural acts and guarantees that have caused a denial of justice, and infringement of art. 24 CE (effective judicial protection). It lies before the Civil Chamber of the Supreme Court. Its admissibility is strict: the Supreme Court rejects appeals that, under the guise of a procedural infringement, conceal disagreement with the tribunal’s assessment of evidence.
Civil cassation (arts. 477-489 LEC)
Civil cassation lies when the judgment is subject to appeal on grounds of amount (exceeding €600,000), by reason of subject matter, or where casational interest exists. Casational interest is the most commonly used ground: it exists when the judgment conflicts with Supreme Court case law, or when there are contradictory judgments from different Provincial Courts on the same question of law. Cassation is not a third instance: it does not review the proven facts, only the law applied.
High-impact special proceedings
Payment order procedure (arts. 812-818 LEC)
The payment order procedure is the most agile mechanism in the LEC for recovering debts. It is for claiming monetary debts that are liquid, due and enforceable, of any amount, evidenced by documents. The application may be made without a barrister or solicitor for amounts below €2,000. The court notifies the debtor to pay or object within 20 days. If the debtor does not respond, enforcement is ordered directly. If there is an objection, the proceedings continue as an ordinary or oral trial. The effectiveness of the payment order procedure depends greatly on the quality of the documentary evidence: signed contracts, accepted invoices and prior payment demands are the basis of a robust application.
Bill of exchange proceedings (arts. 819-827 LEC)
Bill of exchange proceedings offer enhanced protection to holders of bills of exchange, cheques and promissory notes. Art. 821 LEC requires the court to issue a payment order and preventive attachment from the outset, without waiting for the debtor to be heard. Only after that may the debtor object on specific grounds. It is the reference procedure for recovering unpaid commercial paper.
Family proceedings (arts. 769-778 LEC)
Separation, divorce, annulment and proceedings relating to minors have their own rules in Book IV. The reform introduced by Ley 15/2015 on Voluntary Jurisdiction and successive modifications on joint custody have adapted these proceedings over time. The guiding principle is the best interests of the child, which the judge must safeguard of their own motion regardless of what the parties request.
Territorial jurisdiction: the fora in arts. 50 et seq. LEC
Territorial jurisdiction determines which court, among all courts of the same order and level, must hear a case. The general forum for natural persons is the defendant’s domicile (art. 50 LEC); for legal persons, it is their registered office. Special fora apply to certain matters: for real actions over immovables, the court of the place where the property is located (art. 52.1.1.º LEC); for contracts, the court of the place where the obligation was to be performed; for extra-contractual liability, the court of the place where the event occurred. Many contractual relationships include express submission clauses to a specific court, which the LEC accepts with certain limitations in consumer contracts.
Key procedural deadlines under the LEC
Failure to comply with procedural deadlines has serious consequences: preclusion of steps, declaration of default and, ultimately, finality of unfavourable decisions. The most important deadlines are:
- Defence in ordinary trial: 20 working days (art. 404).
- Defence to counterclaim: 20 working days (art. 407).
- Lodging of appeal: 20 working days from notification of judgment (art. 457).
- Objection in payment order proceedings: 20 days from notification (art. 815).
- Interlocutory appeal (recurso de reposición): 5 days (art. 452).
- Complaint (recurso de queja): 10 days (art. 495).
- Enforcement of judgment: The enforcement action prescribes 5 years after the decision becomes final (art. 518).
Deadlines are calculated in working days, excluding Saturdays, Sundays and public holidays. In August, procedural deadlines are suspended (art. 183.1 LOPJ), except in proceedings declared urgent.
Costs: the objective losing-party rule
Art. 394 LEC establishes the objective losing-party principle: whoever loses at first instance must pay the other party’s costs. However, the court may depart from this where there were serious doubts of fact or law. On appeal, the same principle applies: if the appeal is dismissed, costs are awarded against the appellant. Costs include the opposing party’s barrister and solicitor fees, expert fees and clerk’s charges, but not the party’s own legal fees. Assessment of costs is a post-judgment incident that can generate its own litigation.
Mediation and ADR: the alternative to litigation
Ley 5/2012 on mediation in civil and commercial matters introduced mediation as an alternative that parties are required to explore before certain disputes. Although mediation is not generally mandatory, courts may invite parties to attempt it (art. 414 LEC). Mediation agreements approved by the court have direct enforcement value. Mediation has clear advantages in disputes between companies with ongoing relationships, distribution contract disputes or corporate conflicts where a total break in the relationship is undesirable for both parties.
Practical implications for companies
For any company operating in the Spanish commercial market, the LEC has direct implications in several areas:
Contracting. Express submission clauses, agreements on evidence and the requirement of prior demand as a condition for litigation are tools the LEC allows that are worth including in contracts to optimise the position in potential litigation.
Debt collection. The payment order procedure and bill of exchange proceedings are the most efficient channels for recovering documented unpaid debts. A portfolio of debts with signed invoices, delivery notes and clear contracts is recovered faster and at lower cost than a portfolio with poor documentation.
Active litigation. A company that litigates regularly should have internal protocols for preserving documentary evidence (emails, meeting minutes, formal communications) because the LEC requires evidence to be produced at the pre-trial hearing. Late evidence is, as a general rule, not admitted.
Interim measures. In disputes over intellectual property, breach of contract or unfair competition, interim measures (preventive attachment, cease-of-activity orders, judicial deposit) may be strategically more relevant than the final judgment, which can take years to obtain.
The LEC and commercial civil litigation
The Commercial Courts hear disputes relating to companies, insolvency proceedings, industrial and intellectual property, unfair competition, advertising and other commercial matters (art. 86 ter LOPJ). The applicable procedure is that of the LEC, with certain specialties specific to commercial litigation: greater expert complexity, longer timescales given the sophistication of the matter, and a more commercially aware judicial practice.
Conclusion and BMC guidance
The LEC is a technically demanding statute. Its deadlines are peremptory, its formal requirements are not mere formalities, and its appeals have increasingly strict filters. For a Spanish company, knowing the rules of the civil procedural game is as important as knowing the rules of the market in which it operates.
At BMC we accompany companies at every stage of civil proceedings: from drafting contracts designed to provide a litigation advantage if needed, to procedural representation in ordinary trials, payment order procedures and appeals before the Provincial Courts. The team includes the specialist expertise of Raúl Herrera García (ICAM), with extensive experience in civil and commercial litigation, to advise on the viability and strategy of any claim or defence.
